# 36-Region Global Deployment Blueprint
## Overview
This document defines the latency-aware and balanced 36-region global deployment blueprint for the DeFi Oracle Meta Mainnet (ChainID 138).
**Design Principles:**
- Latency-aware: Regions grouped into low-latency "rings" for consensus optimization
- Balanced: Even geographic distribution across all continents
- Quota-optimized: All regions within 10 vCPU per region limit
- Practical: All regions are non-US commercial Azure regions
---

---
## 🎯 Latency-Aware Architecture
The 36 regions are organized into **four low-latency rings**:
### Ring 1: Europe (14 regions)
- Very tight RTT between NL, IE, DE, FR, UK, etc.
- **Primary regions**: West Europe, North Europe, France Central, Germany West Central, UK South, Switzerland North
- Suitable for fast consensus rounds
### Ring 2: Asia Pacific (13 regions)
- JapanKoreaSE AsiaIndiaAustralia cluster
- **Primary regions**: East Asia, Southeast Asia, Japan East, Australia East, Central India
- Optimized for APAC region performance
### Ring 3: Middle East + Africa (4 regions)
- UAE, Qatar, Israel, South Africa
- Provides regional coverage and backup validators
### Ring 4: Americas Non-US (5 regions)
- Canada, Brazil, Chile, Mexico
- **Primary region**: Canada Central
- Western hemisphere coverage
### Consensus Strategy
- **60-70% of producing validators** in Europe + Asia rings (lower latency)
- **30-40% geo-distributed backup validators** across all rings
- Block times: 2-4s (QBFT/IBFT2) with geo-aware committee selection
---
## 📋 Node Distribution Blueprint
### Design Rules
- Each node = **2 vCPUs**
- Each region must stay **≤ 10 vCPUs**
- Even, supportable patterns across all regions
### Allocation Strategy
**Every region: 2 System Nodes**
- 2 × 2 vCPUs = **4 vCPUs** per region
**Validators:**
- **12 "primary" regions**: **2 Validators** each (4 vCPUs)
- **Remaining 24 regions**: **1 Validator** each (2 vCPUs)
### Per-Region Totals
**Primary 12 regions:**
- 2 System + 2 Validators = 4 VMs, **8 vCPUs**
**Other 24 regions:**
- 2 System + 1 Validator = 3 VMs, **6 vCPUs**
---
## 📊 Primary Regions (2 Validators Each - 8 vCPUs)
| Region | Geography | System Nodes | Validator Nodes | Total VMs | Total vCPUs |
|--------|-----------|--------------|-----------------|-----------|-------------|
| West Europe | Europe | 2 | 2 | 4 | 8 |
| North Europe | Europe | 2 | 2 | 4 | 8 |
| France Central | Europe | 2 | 2 | 4 | 8 |
| Germany West Central | Europe | 2 | 2 | 4 | 8 |
| UK South | Europe | 2 | 2 | 4 | 8 |
| Switzerland North | Europe | 2 | 2 | 4 | 8 |
| East Asia | APAC | 2 | 2 | 4 | 8 |
| Southeast Asia | APAC | 2 | 2 | 4 | 8 |
| Japan East | APAC | 2 | 2 | 4 | 8 |
| Australia East | APAC | 2 | 2 | 4 | 8 |
| Central India | APAC | 2 | 2 | 4 | 8 |
| Canada Central | Americas | 2 | 2 | 4 | 8 |
**Subtotal (Primary 12):**
- System Nodes: 12 × 2 = **24**
- Validator Nodes: 12 × 2 = **24**
- Total VMs: 12 × 4 = **48**
- Total vCPUs: 48 × 2 = **96**
---
## 📊 Remaining Regions (1 Validator Each - 6 vCPUs)
All of these get: **2 System, 1 Validator****3 VMs, 6 vCPUs**.
| Region | Geography | System Nodes | Validator Nodes | Total VMs | Total vCPUs |
|--------|-----------|--------------|-----------------|-----------|-------------|
| UK West | Europe | 2 | 1 | 3 | 6 |
| Sweden Central | Europe | 2 | 1 | 3 | 6 |
| Norway East | Europe | 2 | 1 | 3 | 6 |
| Poland Central | Europe | 2 | 1 | 3 | 6 |

| Chile Central | Americas | 2 | 1 | 3 | 6 |
| Mexico Central | Americas | 2 | 1 | 3 | 6 |
| South Africa North | Africa | 2 | 1 | 3 | 6 |
**Subtotal (Remaining 24):**
- System Nodes: 24 × 2 = **48**
- Validator Nodes: 24 × 1 = **24**
- Total VMs: 24 × 3 = **72**
- Total vCPUs: 72 × 2 = **144**
---
## 🔚 Global Totals (36 Regions)
- **System Nodes:** 24 + 48 = **72**
- **Validator Nodes:** 24 + 24 = **48**
- **Total VMs:** 48 + 72 = **120**
- **Total vCPUs:** 96 + 144 = **240**
- **All regions ≤ 8 vCPUs (< 10 quota limit)** ✅
---
## ⚙️ West Europe Admin-Only Variant
If **West Europe** should be purely for admin/control plane (no workload nodes):
### Re-allocation Strategy
1. **Set West Europe to 0/0** (no System/Validator nodes)
2. **Re-assign its nodes:**
- +1 System +1 Validator → **North Europe** (8 → 10 vCPUs)
- +1 System +1 Validator → **Belgium Central** (6 → 10 vCPUs)
### Updated Totals (Admin Variant)
| Region | System Nodes | Validator Nodes | Total vCPUs |
|--------|--------------|-----------------|-------------|
| West Europe | 0 | 0 | 0 (admin only) |
| North Europe | 3 | 3 | 12 ❌ (exceeds quota) |
| Belgium Central | 3 | 2 | 10 ✅ |
**Note:** North Europe would exceed 10 vCPU limit. Alternative allocation needed.
**Better Re-allocation:**
- +1 System +1 Validator → **Belgium Central** (6 → 10 vCPUs)
- +1 System +1 Validator → **Netherlands** (if available) or split:
- +1 System → **Sweden Central** (6 → 8 vCPUs)
- +1 Validator → **Poland Central** (6 → 8 vCPUs)
---
## 🎯 Next Steps
1. **Map Kubernetes clusters & pod densities** onto this 36-region layout
2. **Define QBFT/IBFT2 geo-aware committee configuration**:
- Primary regions (60-70% producing validators)
- Secondary regions (30-40% backup validators)
- Latency-optimized consensus rounds
3. **Create Terraform configuration** for all 36 regions
4. **Generate deployment scripts** with region-specific configurations
5. **Implement geo-aware validator selection** logic

# Admin Address Options
**Date**: 2025-12-11
**Status**: Updated - Defender No Longer Available
---
## ⚠️ Important Update
**OpenZeppelin Defender is no longer offered**. The deployment scripts have been updated to use direct admin addresses instead.
---
## 🔐 Admin Address Options
### Option 1: Multisig Wallet (Recommended)
**Best for**: Production deployments requiring multiple approvals
**Options**:
- **Gnosis Safe**: https://gnosis-safe.io/
- Most popular multisig solution
- Supports multiple chains
- Web interface for managing transactions
- Configurable threshold (e.g., 2-of-3, 3-of-5)
- **Safe (formerly Gnosis Safe)**: https://safe.global/
- Updated branding, same functionality
- Enhanced security features
- Mobile app support
**Setup**:
1. Create a Safe wallet on Ethereum Mainnet
2. Add signers (e.g., 3-5 trusted addresses)
3. Set threshold (e.g., 2-of-3)
4. Copy the Safe address
5. Set in `.env`:
```bash
TETHER_ADMIN=<safe_wallet_address>
MIRROR_ADMIN=<safe_wallet_address> # Can be same or different
```
**Benefits**:
- ✅ Multiple approvals required
- ✅ Enhanced security
- ✅ Audit trail
- ✅ Recovery options
- ✅ No single point of failure
---
### Option 2: EOA (Externally Owned Account)
**Best for**: Development, testing, or simple deployments
**Setup**:
1. Use a secure wallet (hardware wallet recommended)
2. Copy the address
3. Set in `.env`:
```bash
TETHER_ADMIN=<wallet_address>
MIRROR_ADMIN=<wallet_address>
```
**Security Considerations**:
- ⚠️ Single point of failure
- ⚠️ Private key must be secured
- ⚠️ Consider using hardware wallet
- ⚠️ Not recommended for production
---
### Option 3: Custom Access Control Contract
**Best for**: Complex permission requirements
You can deploy a custom access control contract that implements:
- Role-based access control
- Timelock delays
- Multi-signature requirements
- Custom permission logic
**Example**: Deploy OpenZeppelin's `AccessControl` or `AccessManager` and set it as admin.
---
## 📋 Current Implementation
### Deployment Scripts
Both deployment scripts now use:
- `TETHER_ADMIN` for MainnetTether
- `MIRROR_ADMIN` for TransactionMirror
```solidity
address admin = vm.envAddress("TETHER_ADMIN");
require(admin != address(0), "TETHER_ADMIN not set in .env");
```
### Contract Pattern
Contracts use simple admin pattern (similar to OpenZeppelin's `Ownable`):
- Single `admin` address
- `onlyAdmin` modifier for protected functions
- `setAdmin()` function to transfer admin (requires current admin)
---
## 🚀 Deployment Steps
### 1. Choose Admin Address Type
**Recommended**: Gnosis Safe (multisig)
### 2. Set Up Admin Address
**For Multisig (Gnosis Safe)**:
1. Go to https://safe.global/
2. Create a new Safe on Ethereum Mainnet
3. Add signers (minimum 2, recommended 3-5)
4. Set threshold (e.g., 2-of-3)
5. Complete setup and copy Safe address
**For EOA**:
1. Use secure wallet (hardware wallet recommended)
2. Copy wallet address
### 3. Update .env File
```bash
# Admin addresses (multisig recommended)
TETHER_ADMIN=0x... # Your admin address (Safe or EOA)
MIRROR_ADMIN=0x... # Can be same as TETHER_ADMIN or different
# Other required variables
PRIVATE_KEY=0x... # Deployer private key
ETH_MAINNET_RPC_URL=https://eth-mainnet.g.alchemy.com/v2/YOUR_API_KEY
ETHERSCAN_API_KEY=...
```
### 4. Deploy Contracts
```bash
# Deploy MainnetTether
forge script script/DeployMainnetTether.s.sol \
--rpc-url $ETH_MAINNET_RPC_URL \
--private-key $PRIVATE_KEY \
--broadcast \
--verify \
-vvvv
# Deploy TransactionMirror
forge script script/DeployTransactionMirror.s.sol \
--rpc-url $ETH_MAINNET_RPC_URL \
--private-key $PRIVATE_KEY \
--broadcast \
--verify \
--via-ir \
-vvvv
```
---
## 🔒 Security Best Practices
### For Production
1. **Use Multisig**: Always use Gnosis Safe or similar for production
2. **Multiple Signers**: Use 3-5 signers with 2-of-3 or 3-of-5 threshold
3. **Hardware Wallets**: Use hardware wallets for signers
4. **Separate Admin Addresses**: Consider different admin addresses for different contracts
5. **Regular Reviews**: Periodically review admin addresses and permissions
### For Development/Testing
1. **Testnet First**: Deploy to testnet first
2. **Secure Storage**: Keep private keys secure
3. **Hardware Wallet**: Use hardware wallet even for testing
4. **Documentation**: Document admin addresses and recovery procedures
---
## 📝 Post-Deployment
### Verify Admin Address
After deployment, verify the admin address:
```bash
# Check MainnetTether admin
cast call <MAINNET_TETHER_ADDRESS> "admin()" --rpc-url $ETH_MAINNET_RPC_URL
# Check TransactionMirror admin
cast call <TRANSACTION_MIRROR_ADDRESS> "admin()" --rpc-url $ETH_MAINNET_RPC_URL
```
### Transfer Admin (If Needed)
If you need to transfer admin to a different address:
```bash
# Transfer MainnetTether admin
cast send <MAINNET_TETHER_ADDRESS> \
"setAdmin(address)" \
<NEW_ADMIN_ADDRESS> \
--rpc-url $ETH_MAINNET_RPC_URL \
--private-key $CURRENT_ADMIN_PRIVATE_KEY
# Transfer TransactionMirror admin
cast send <TRANSACTION_MIRROR_ADDRESS> \
"setAdmin(address)" \
<NEW_ADMIN_ADDRESS> \
--rpc-url $ETH_MAINNET_RPC_URL \
--private-key $CURRENT_ADMIN_PRIVATE_KEY
```
**Note**: For multisig, execute this transaction through the Safe interface.
---
## 🔄 Migration from Defender
If you previously used Defender:
1. **Create New Admin Address**: Set up Gnosis Safe or choose EOA
2. **Update .env**: Replace `DEFENDER_ADMIN` with `TETHER_ADMIN`/`MIRROR_ADMIN`
3. **Deploy New Contracts**: Deploy with new admin addresses
4. **Or Transfer Admin**: If contracts already deployed, transfer admin to new address

# Automated Deployment Ready
**Date**: 2025-12-11
**Status**: Scripts Ready - Awaiting RPC Configuration
---
## 🚀 Automated Deployment Script
A deployment script has been created that will automatically deploy both contracts once the RPC is configured:
**Script**: `scripts/deployment/deploy-mainnet-tether-mirror.sh`
### Usage
```bash
cd /home/intlc/projects/smom-dbis-138
./scripts/deployment/deploy-mainnet-tether-mirror.sh
```
### What It Does
1. **Checks RPC Connection**
- Tests connection to `ETHEREUM_MAINNET_RPC`
- Provides clear error message if connection fails
2. **Deploys MainnetTether**
- Uses deployer address as admin (EOA)
- Automatically verifies on Etherscan
- Updates `.env` with deployed address
3. **Deploys TransactionMirror**
- Uses deployer address as admin (EOA)
- Automatically verifies on Etherscan
- Updates `.env` with deployed address
4. **Provides Summary**
- Shows deployed addresses
- Provides Etherscan links
- Lists next steps
---
## ⚠️ Current Blocker
**Infura RPC Authentication Issue**
The script will automatically detect this and provide instructions:
```
❌ RPC connection failed!
Please fix the Infura RPC configuration:
1. Go to https://infura.io/
2. Project ID: 43b945b33d58463a9246cf5ca8aa6286
3. Settings → Disable 'Private Key Only'
4. Save and run this script again
```
---
## ✅ Once RPC is Fixed
Simply run the script again:
```bash
./scripts/deployment/deploy-mainnet-tether-mirror.sh
```
The script will:
- ✅ Test RPC connection
- ✅ Deploy MainnetTether
- ✅ Deploy TransactionMirror
- ✅ Update `.env` with addresses
- ✅ Provide summary with Etherscan links
---
## 📋 Configuration
**Deployer**: `0x4A666F96fC8764181194447A7dFdb7d471b301C8`
**Admin**: Deployer address (EOA - no multisig)
**RPC**: `$ETHEREUM_MAINNET_RPC` (from `.env`)
**Verification**: Automatic via `--verify` flag

## ⚙️ Configuration Steps
### 1. Set Destination Chains
For each bridge, configure destination chain selectors:
```solidity
// Example: Configure BSC bridge to send to Polygon
bridge.setDestinationChain(
POLYGON_SELECTOR, // 4051577828743386545
polygonBridgeAddress
);
```
### 2. Fund Bridges with LINK
Each bridge needs LINK tokens for CCIP fees:
```bash
# Transfer LINK to bridge
cast send $LINK_TOKEN \
"transfer(address,uint256)" \
$BRIDGE_ADDRESS \
$AMOUNT \
--rpc-url $RPC_URL \
--private-key $PRIVATE_KEY
```
**Recommended**: 10 LINK per bridge for initial operations
### 3. Enable Bridges
Enable bridges for cross-chain operations:
```solidity
bridge.enable();
```
### 4. Set Fee Configuration
Configure fee parameters if needed:
```solidity
bridge.setFeeConfig(...);
```

## ⚠️ Important Notes
1. **CCIPLogger**: May require Hardhat/OpenZeppelin dependencies. If Foundry deployment fails, use:
```bash
npm run deploy:logger:mainnet
```
2. **WETH9/WETH10**: Script checks for existing addresses in `.env`. If configured, will use existing instead of deploying new.
3. **CCIP Configuration**: Each chain requires specific CCIP router and LINK token addresses in `.env`.
4. **Gas Estimates**: Based on typical contract sizes. Actual gas may vary.

## 📋 Contract Ownership Details
### CCIPWETH9Bridge & CCIPWETH10Bridge
**Ownership Model**: Admin-based
**Admin Function**: `admin()` returns `address`
**Initial Admin**: Set to `msg.sender` (deployer) in constructor
**Admin Capabilities**:
- Add/remove destination chains
- Update destination chain configurations
- Change fee token address
- Transfer admin to new address
**Verification**: ✅ All bridge contracts have deployer as admin
### WETH9 & WETH10
**Ownership Model**: None
**Reason**: Standard ERC20 tokens without ownership
**Design**: Immutable contracts (no admin functions)
**Verification**: No ownership to verify (by design)
---
## 🔍 Verification Method
Ownership was verified using:
1. **Script**: `scripts/deployment/verify-contract-ownership.sh`
2. **Method**: Direct contract calls to `admin()` function
3. **Comparison**: Admin address vs deployer address
4. **Result**: All bridge contracts verified as owned by deployer
---
## ✅ Summary
### Ownership Status
- **Bridge Contracts**: ✅ 12/12 verified (deployer is admin)
- BSC: 2/2 ✅
- Polygon: 2/2 ✅
- Avalanche: 2/2 ✅
- Base: 2/2 ✅
- Arbitrum: 2/2 ✅
- Optimism: 2/2 ✅
- **Token Contracts**: 12/12 no ownership (by design)

- **Total Verified**: ✅ All contracts with ownership verified
- **Deployer Address**: `0x4A666F96fC8764181194447A7dFdb7d471b301C8`
### Security Notes
1. **Bridge Admin**: All bridge contracts are owned by deployer
2. **Token Immutability**: WETH9/WETH10 are immutable (no ownership)
3. **Admin Transfer**: Admin can be transferred if needed
4. **Multi-sig Consideration**: Consider transferring admin to multi-sig for production
---
## 🔧 Admin Functions Available
### CCIPWETH9Bridge & CCIPWETH10Bridge
```solidity
// Check current admin
address admin = bridge.admin();
// Transfer admin (only current admin can call)
bridge.transferAdmin(newAdmin);
// Add destination chain (only admin)
bridge.addDestination(chainSelector, receiverBridge);
// Remove destination chain (only admin)
bridge.removeDestination(chainSelector);
// Update destination chain (only admin)
bridge.updateDestination(chainSelector, receiverBridge);
// Change fee token (only admin)
bridge.setFeeToken(newFeeToken);
```
---
## 📝 Recommendations
1. **Multi-sig Setup**: Consider transferring admin to a multi-sig wallet for enhanced security
2. **Admin Backup**: Document admin transfer procedures
3. **Access Control**: Review admin functions and ensure proper access control

# Contract Review Report - MainnetTether & TransactionMirror
**Date**: 2025-12-11
**Reviewer**: Automated Code Review
**Status**: Pre-Deployment Review
---
## 📋 Contracts Reviewed
1. **MainnetTether.sol** - State proof anchoring contract
2. **TransactionMirror.sol** - Transaction mirroring contract
3. **DeployMainnetTether.s.sol** - Deployment script
4. **DeployTransactionMirror.s.sol** - Deployment script
---
## ✅ Code Quality Review
### MainnetTether.sol
#### ✅ Strengths
- ✅ Proper access control with `onlyAdmin` modifier
- ✅ Pausability implemented correctly
- ✅ Replay protection via `processed` mapping
- ✅ Input validation (zero address checks, non-zero values)
- ✅ Events properly indexed for searchability
- ✅ Clear documentation and comments
- ✅ Follows existing codebase patterns
#### ⚠️ Issues Found
1. **Missing Validation: Block Number Ordering**
- **Issue**: No validation that block numbers are sequential or increasing
- **Impact**: Medium - Could anchor blocks out of order
- **Recommendation**: Add validation to ensure `blockNumber > lastAnchoredBlock` or allow out-of-order with explicit flag
2. **Missing Validation: Signature Verification**
- **Issue**: Signatures are stored but not verified on-chain
- **Impact**: Low - Off-chain service should verify, but on-chain verification would be stronger
- **Recommendation**: Consider adding signature verification if validator addresses are known
3. **Gas Optimization: Array Growth**
- **Issue**: `anchoredBlocks` array grows unbounded
- **Impact**: Low - Could become expensive to query over time
- **Recommendation**: Consider pagination or limit array size for queries
4. **Missing Feature: Block Range Queries**
- **Issue**: No function to get all blocks in a range
- **Impact**: Low - Convenience feature
- **Recommendation**: Add `getAnchoredBlocksInRange(uint256 start, uint256 end)` if needed
5. **Missing Event: Previous Block Hash**
- **Issue**: `StateProofAnchored` event doesn't include `previousBlockHash`
- **Impact**: Low - Could be useful for chain verification
- **Recommendation**: Add to event if needed for off-chain verification
---
### TransactionMirror.sol
#### ✅ Strengths
- ✅ Proper access control with `onlyAdmin` modifier
- ✅ Pausability implemented correctly
- ✅ Replay protection via `processed` mapping
- ✅ Batch support for gas efficiency
- ✅ Events properly indexed for Etherscan searchability
- ✅ Clear documentation and comments
- ✅ Follows existing codebase patterns
#### ⚠️ Issues Found
1. **Missing Validation: Block Number Ordering**
- **Issue**: No validation that transactions are in block order
- **Impact**: Low - Transactions can be mirrored out of order
- **Recommendation**: Add optional ordering validation if needed
2. **Gas Optimization: Batch Size Limit**
- **Issue**: No limit on batch size - could hit gas limit
- **Impact**: Medium - Large batches could fail
- **Recommendation**: Add `MAX_BATCH_SIZE` constant and validation
3. **Missing Validation: Timestamp Reasonableness**
- **Issue**: No validation that timestamps are reasonable
- **Impact**: Low - Could store invalid timestamps
- **Recommendation**: Add timestamp validation (e.g., not in future, not too old)
4. **Missing Feature: Filtered Queries**
- **Issue**: No way to query transactions by address, block range, or value
- **Impact**: Low - Convenience feature
- **Recommendation**: Add filtered query functions if needed
5. **Potential Issue: Data Size**
- **Issue**: `data` field can be large, increasing gas costs
- **Impact**: Medium - Large transaction data could be expensive
- **Recommendation**: Consider storing only data hash or limiting data size
6. **Missing Event: Transaction Data Hash**
- **Issue**: Event doesn't include data hash for verification

---
## 🐛 Potential Bugs
### MainnetTether.sol
1. **Block Number Collision**
- **Issue**: If same block number is anchored twice with different data, second will fail
- **Current Behavior**: Correctly prevents duplicate block numbers
- **Status**: ✅ Working as intended
2. **Proof Hash Collision**
- **Issue**: Extremely unlikely, but possible hash collision
- **Current Behavior**: Uses multiple fields in hash calculation
- **Status**: ✅ Acceptable risk
### TransactionMirror.sol
1. **Batch Array Mismatch**
- **Issue**: Arrays must be same length
- **Current Behavior**: Correctly validates array lengths
- **Status**: ✅ Working as intended
2. **Empty Batch**
- **Issue**: Empty batch would emit event with count=0
- **Current Behavior**: Would work but wasteful
- **Recommendation**: Add check `require(txHashes.length > 0, "empty batch")`
---
## 📊 Gas Optimization Opportunities
### MainnetTether.sol
- ✅ Uses `calldata` for signatures (good)
- ⚠️ Consider: Packing struct fields (if possible)
- ⚠️ Consider: Using events instead of storage for historical data
### TransactionMirror.sol

# Defender Access Control Integration
**Date**: 2025-12-11
**Reference**: [OpenZeppelin Access Control Documentation](https://docs.openzeppelin.com/contracts/5.x/access-control#access-management)
---
## 📚 Current Implementation
### MainnetTether & TransactionMirror
Both contracts use a **simple admin pattern** (similar to OpenZeppelin's `Ownable`):
```solidity
address public admin;
bool public paused;
modifier onlyAdmin() {
require(msg.sender == admin, "only admin");
_;
}
```
This is equivalent to OpenZeppelin's `Ownable` pattern, where:
- A single `admin` address controls all administrative functions
- Functions are protected with `onlyAdmin` modifier
- Admin can be changed via `setAdmin()` function
---
## 🔐 Defender Integration
### Using Defender as Admin
According to OpenZeppelin's documentation, **"a contract can also be the owner of another one"**. This means:
**Defender Relayer Address** can be set as the `admin` of our contracts
This provides:
- Automated transaction execution
- Gas price optimization
- Transaction monitoring and alerts
- Multi-signature support (via Defender)
- Rate limiting and security policies
- Non-custodial key management
### Current Setup
Our deployment scripts are configured to:
1. Check for `DEFENDER_ADMIN` environment variable first
2. Fall back to `TETHER_ADMIN`/`MIRROR_ADMIN` if Defender not set
3. Deploy contracts with Defender address as `admin`
```solidity
// Deployment script pattern
address admin = vm.envOr("DEFENDER_ADMIN", vm.envOr("TETHER_ADMIN", address(0)));
MainnetTether tether = new MainnetTether(admin);
```
---
## 🚀 Advanced Access Control Options
### Option 1: Current Simple Admin (Recommended for Now)
**Status**: ✅ **Currently Implemented**
- Simple and effective
- Single Defender address as admin
- All admin functions controlled by Defender
- Easy to understand and audit
**Use Case**: Perfect for contracts with a single administrative role
### Option 2: AccessControl (Role-Based)
If you need more granular permissions in the future, you could upgrade to OpenZeppelin's `AccessControl`:
```solidity
import {AccessControl} from "@openzeppelin/contracts/access/AccessControl.sol";
contract MainnetTether is AccessControl {
bytes32 public constant ANCHOR_ROLE = keccak256("ANCHOR_ROLE");
bytes32 public constant PAUSE_ROLE = keccak256("PAUSE_ROLE");
constructor(address defenderAdmin) {
_grantRole(DEFAULT_ADMIN_ROLE, defenderAdmin);
}
function anchorStateProof(...) external onlyRole(ANCHOR_ROLE) {
// Only accounts with ANCHOR_ROLE can call this
}
function pause() external onlyRole(PAUSE_ROLE) {
// Only accounts with PAUSE_ROLE can call this
}
}
```
**Benefits**:
- Multiple roles (e.g., `ANCHOR_ROLE`, `PAUSE_ROLE`)
- Different permissions for different functions
- Defender can be `DEFAULT_ADMIN_ROLE` to manage all roles
**When to Use**: If you need different accounts for different functions
### Option 3: AccessManager (Centralized Permission Management)
For complex protocols with multiple contracts, OpenZeppelin's `AccessManager` provides centralized permission management:
```solidity
import {AccessManaged} from "@openzeppelin/contracts/access/manager/AccessManaged.sol";
contract MainnetTether is AccessManaged {
constructor(address accessManager) AccessManaged(accessManager) {}
function anchorStateProof(...) public restricted {
// Access controlled by AccessManager
}
}
```
**Benefits**:
- Centralized permission management across all contracts
- Execution delays for security
- Role-based access with delays
- Defender can be the initial admin
**When to Use**: For complex multi-contract systems
---
## 📋 Defender Configuration
### Setting Up Defender
1. **Create Defender Relayer**
- Go to [OpenZeppelin Defender](https://defender.openzeppelin.com/)
- Create a new relayer
- Copy the relayer address
2. **Configure Environment**
```bash
DEFENDER_ADMIN=<defender_relayer_address>
```
3. **Deploy Contracts**
- Contracts will use Defender address as admin
- All admin functions can be executed via Defender
4. **Set Up Defender Actions**
- Create Defender actions for `anchorStateProof()`
- Create Defender actions for `mirrorTransaction()`
- Configure Defender policies and rate limits
### Defender Benefits
According to OpenZeppelin's best practices:
- ✅ **Automated Execution**: Defender can execute transactions automatically
- ✅ **Gas Optimization**: Defender optimizes gas prices
- ✅ **Monitoring**: Real-time alerts for contract events
- ✅ **Security**: Multi-signature support and rate limiting
- ✅ **Non-Custodial**: Keys managed securely by Defender
---
## 🔄 Migration Path
### Current → AccessControl (If Needed)
If you need role-based access control later:
1. Deploy new version with `AccessControl`
2. Grant `DEFAULT_ADMIN_ROLE` to Defender
3. Set up specific roles (e.g., `ANCHOR_ROLE`, `PAUSE_ROLE`)
4. Migrate admin functions to use `onlyRole` modifiers
### Current → AccessManager (If Needed)
For centralized permission management:
1. Deploy `AccessManager` contract
2. Set Defender as initial admin
3. Update contracts to inherit `AccessManaged`
4. Configure roles and permissions in AccessManager
---
## ✅ Recommendation
**For MainnetTether and TransactionMirror**:
✅ **Keep the current simple admin pattern** with Defender as admin
**Reasons**:
- Simple and effective for single-admin contracts
- Defender provides all necessary security features
- Easy to understand and audit
- No need for complex role-based access control
- Can upgrade to `AccessControl` or `AccessManager` later if needed

# Defender Deployment - Ready Status
**Date**: 2025-12-11
**Status**: ✅ Scripts Updated - Configuration Needed
---
## ✅ What's Been Done
### Deployment Scripts Updated
Both deployment scripts have been updated to use Defender:
1. **DeployMainnetTether.s.sol**
- Now checks for `DEFENDER_ADMIN` first
- Falls back to `TETHER_ADMIN` if Defender not set
- Logs Defender admin address on deployment
2. **DeployTransactionMirror.s.sol**
- Now checks for `DEFENDER_ADMIN` first
- Falls back to `MIRROR_ADMIN` if Defender not set
- Logs Defender admin address on deployment
---
## ⚠️ Configuration Required
### 1. Set Defender Admin Address
Add to `.env` file:
```bash
DEFENDER_ADMIN=0x... # Your Defender relayer address
```
**How to get Defender address:**
1. Go to OpenZeppelin Defender: https://defender.openzeppelin.com/
2. Create or select a relayer
3. Copy the relayer address
4. Add to `.env` as `DEFENDER_ADMIN`
### 2. Update RPC URL
The current RPC URL has a placeholder. Update in `.env`:
```bash
ETH_MAINNET_RPC_URL=https://eth-mainnet.g.alchemy.com/v2/YOUR_ACTUAL_API_KEY
```
Replace `YOUR_ACTUAL_API_KEY` with your real Alchemy API key.
---

## ✅ Verification Steps
After updating `.env`:
1. **Test RPC Connection:**
```bash
cast block-number --rpc-url $ETH_MAINNET_RPC_URL
```
Should return current block number.
2. **Verify Defender Address:**
```bash
echo $DEFENDER_ADMIN
```
Should show your Defender relayer address.
3. **Check Deployer Balance:**
```bash
cast balance $(cast wallet address $PRIVATE_KEY) --rpc-url $ETH_MAINNET_RPC_URL
```
Should show sufficient ETH for gas.
---
## 📝 Environment Variables Summary
Required in `.env`:
- ✅ `PRIVATE_KEY` - Already set
- ✅ `ETH_MAINNET_RPC_URL` - Needs actual API key (currently has placeholder)
- ✅ `ETHERSCAN_API_KEY` - Already set
- ⚠️ `DEFENDER_ADMIN` - Needs to be added
Optional (fallback):
- `TETHER_ADMIN` - Used if `DEFENDER_ADMIN` not set
- `MIRROR_ADMIN` - Used if `DEFENDER_ADMIN` not set

# Defender Deprecated - Migration Guide
**Date**: 2025-12-11
**Status**: Defender No Longer Available
---
## ⚠️ Important Notice
**OpenZeppelin Defender is no longer offered**. All references to Defender have been removed from the deployment scripts and documentation.
---
## ✅ What's Been Updated
### Deployment Scripts
-`DeployMainnetTether.s.sol` - Removed Defender references
-`DeployTransactionMirror.s.sol` - Removed Defender references
- ✅ Now use `TETHER_ADMIN` and `MIRROR_ADMIN` directly
### Documentation
- ✅ Updated to use admin addresses (multisig or EOA)
- ✅ Removed Defender-specific instructions
- ✅ Added Gnosis Safe as recommended alternative
---
## 🔄 Migration Steps
### 1. Choose New Admin Solution
**Recommended**: Gnosis Safe (multisig wallet)
### 2. Set Up Admin Address
1. Create Gnosis Safe wallet: https://safe.global/
2. Add signers (3-5 recommended)
3. Set threshold (e.g., 2-of-3)
4. Copy Safe address
### 3. Update .env File
Remove any `DEFENDER_ADMIN` references and add:
```bash
TETHER_ADMIN=<your_admin_address> # Gnosis Safe or EOA
MIRROR_ADMIN=<your_admin_address> # Can be same or different
```
### 4. Deploy Contracts
Deployment scripts now work with standard admin addresses:
```bash
forge script script/DeployMainnetTether.s.sol \
--rpc-url $ETH_MAINNET_RPC_URL \
--private-key $PRIVATE_KEY \
--broadcast \
--verify \
-vvvv
```
---
## 📚 Alternative Solutions
### Gnosis Safe (Recommended)
- Multi-signature wallet
- Web interface
- Multiple chain support
- Enhanced security
### EOA (Externally Owned Account)
- Simple wallet address
- For development/testing
- Use hardware wallet for security
### Custom Access Control
- OpenZeppelin AccessControl
- OpenZeppelin AccessManager
- Custom permission contracts

## ⚠️ CCIPLogger Status
**CCIPLogger** was not deployed via Foundry (placeholder returns `address(0)`).
**Reason**: CCIPLogger uses Hardhat/OpenZeppelin dependencies and needs separate deployment.
**Next Steps**:
- Deploy CCIPLogger separately using Hardhat script (if available)
- Or implement CCIPLogger deployment in Foundry (if contract is available)

# Deployment Status Update - 36-Region Infrastructure
**Last Updated:** $(date)
---
## 📊 Current Status
### Phase 2: Infrastructure Deployment
**Status:** ⚠️ **PARTIALLY COMPLETE** (with errors)
**Progress Metrics:**
- ✅ Resources Created: 143/224 (63.8%)
- ⚠️ Errors Detected: 38
- ✅ Ready Clusters: 2/36
- Belgium Central (belgiumcentral)
- West Europe (westeurope)
**Terraform Apply:** ✅ Completed (with errors)
---
## ❌ Issues Detected
### 1. Log Analytics Region Support
**Issue:** `austriaeast` region doesn't support Log Analytics workspaces
**Error:**
```
LocationNotAvailableForResourceType: The provided location 'austriaeast' is not available
for resource type 'Microsoft.OperationalInsights/workspaces'
```
**Fix Applied:**
- Added `austriaeast` to `log_analytics_location` mapping
- Now uses `westeurope` for Log Analytics (same as belgiumcentral and westindia)
**Location:** `terraform/well-architected/cloud-sovereignty/modules/region/main.tf`
### 2. Subnet Delegation Errors
**Issue:** Multiple subnet update errors across regions:
- polandcentral
- northeurope
- switzerlandnorth
- japaneast
- australiaeast
- francecentral
**Likely Cause:** Subnets already exist with different configurations, causing update conflicts
**Status:** Needs investigation and potential manual cleanup
---
## ✅ Fixes Applied
1. **Log Analytics Mapping:**
- Updated `modules/region/main.tf` to include `austriaeast` in the mapping
- Now uses `westeurope` for Log Analytics workspace location
---
## ⏱️ Time Estimates
### Phase 2 (Infrastructure)
**Completed:**
- Elapsed: ~45 minutes (estimated)
- Resources: 143/224 created (63.8%)
**Remaining:**
- Resources: 81 remaining
- Time: ~25-30 minutes (after fixes)
### All Phases
- **Phase 2:** ~25-30 minutes (remaining)
- **Phase 3:** ~20 minutes (Kubernetes Configuration)
- **Phase 4:** ~45 minutes (Besu Network Deployment)
- **Phase 5:** ~30 minutes (Application Stack)
- **Phase 6:** ~20 minutes (Cross-Chain & Integration)
- **Phase 7:** ~15 minutes (Verification & Testing)
- **Phase 8:** ~8 minutes (Documentation & Handoff)
**Total Remaining:** ~3-4 hours
---
## 🚀 Next Steps
### Immediate Actions
1. **Re-apply Terraform with fixes:**
```bash
cd terraform/well-architected/cloud-sovereignty
terraform apply -parallelism=128 -auto-approve
```
2. **Monitor deployment:**
```bash
./scripts/deployment/monitor-36-region-deployment.sh
```
3. **Investigate subnet errors:**
```bash
tail -100 /tmp/terraform-apply-36regions-*.log | grep -A 5 "Error.*subnet"
```
### Subnet Error Resolution
If subnet errors persist:
1. Check existing subnet configurations in Azure Portal
2. Consider deleting and recreating problematic subnets
3. Ensure subnet delegation is correctly configured before AKS cluster creation

- Besu CLI tools
- Foundry (forge, cast, anvil)
## Step 1: Generate Genesis and Keys
1. Generate validator keys:
```bash
./scripts/key-management/generate-validator-keys.sh 4
```
2. Generate oracle keys:
```bash
./scripts/key-management/generate-oracle-keys.sh
```
3. Generate genesis file:
```bash
./scripts/generate-genesis.sh
```
4. Store keys in Azure Key Vault:
```bash
./scripts/key-management/azure-keyvault-setup.sh
```
## Step 2: Deploy Azure Infrastructure (Admin Region + Multi-Region)
1. Navigate to Terraform directory:
```bash
cd terraform
```
2. Initialize Terraform:
```bash
terraform init
```
3. Create terraform.tfvars:
```bash
cp terraform.tfvars.example terraform.tfvars
# Edit terraform.tfvars with your values
```
4. Plan deployment for the West Europe admin cluster:
```bash
terraform plan -lock-timeout=5m
```
5. Apply infrastructure:
```bash
terraform apply -lock-timeout=5m
```
6. (Recommended) Run a **canary multi-region deployment** for a single workload region before rolling out globally:
```bash
cd ..
scripts/deployment/canary-region.sh northeurope
```
7. After the canary region is healthy, roll out to all 36 workload regions:
```bash
cd terraform
terraform plan -lock-timeout=5m
terraform apply -lock-timeout=5m
```
8. Get kubeconfig for the West Europe admin cluster (adjust if you changed names):
```bash
az aks get-credentials --resource-group az-p-wst-rg-comp-001 --name az-p-wst-aks-main --overwrite-existing
```
## Step 3: Deploy Kubernetes Resources
1. Create namespace:
```bash
kubectl apply -f k8s/base/namespace.yaml
```
2. Deploy validators:
```bash
helm install besu-validators ./helm/besu-network -f helm/besu-network/values-validators.yaml -n besu-network
```
3. Deploy sentries:
```bash
helm install besu-sentries ./helm/besu-network -f helm/besu-network/values-sentries.yaml -n besu-network
```
4. Deploy RPC nodes:
```bash
helm install besu-rpc ./helm/besu-network -f helm/besu-network/values-rpc.yaml -n besu-network
```
5. Deploy API gateway:
```bash
kubectl apply -f k8s/gateway/nginx-config.yaml
```
## Step 4: Deploy Monitoring
1. Create monitoring namespace:
```bash
kubectl create namespace monitoring
```
2. Deploy Prometheus:
```bash
kubectl apply -f monitoring/k8s/prometheus.yaml
```
3. Deploy Grafana (optional):
```bash
helm install grafana grafana/grafana -n monitoring
```
## Step 5: Deploy Blockscout
1. Deploy Blockscout database:
```bash
kubectl apply -f k8s/blockscout/deployment.yaml
```
2. Wait for database to be ready:
```bash
kubectl wait --for=condition=ready pod -l app=blockscout-db -n besu-network --timeout=300s
```
3. Blockscout will automatically run migrations on startup.
## Step 6: Deploy Contracts
1. Set environment variables:
```bash
export RPC_URL="https://rpc.d-bis.org"
export PRIVATE_KEY="your-private-key"
```
2. Deploy WETH:
```bash
./scripts/deployment/deploy-weth.sh
```
3. Deploy Multicall:
```bash
./scripts/deployment/deploy-multicall.sh
```
4. Deploy Oracle Aggregator:
```bash
forge script script/DeployOracle.s.sol --rpc-url $RPC_URL --broadcast --private-key $PRIVATE_KEY
```
## Step 7: Deploy Oracle Publisher
1. Update oracle configuration:
```bash
kubectl create configmap oracle-config --from-literal=aggregator_address=<AGGREGATOR_ADDRESS> -n besu-network
```
2. Deploy oracle publisher:
```bash
kubectl apply -f services/oracle-publisher/k8s/deployment.yaml
```
## Step 8: Tatum SDK Integration
1. Install SDK dependencies:
```bash
cd sdk
npm install
```
2. Configure environment:
```bash
cp env.example .env
# Edit .env with your RPC endpoint
```
3. Test connection:
```bash
npm run test
```
4. Run examples:
```bash
# Basic usage
npm run example:basic
# Send transaction
npm run example:transaction
# Deploy contract
npm run example:contract
```
See [Tatum SDK Integration Guide](TATUM_SDK.md) for detailed documentation.
## Step 9: Verification
1. Check node status:
```bash
kubectl get pods -n besu-network
```
2. Check block production:
```bash
kubectl logs -f besu-validator-0 -n besu-network
```
3. Test RPC endpoint:
```bash
curl -X POST https://rpc.d-bis.org \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'
```
4. Test Tatum SDK integration:
```bash
cd sdk
npm run test
npm run smoke-test
```

# Deployment Clarification: WETH vs Bridge Contracts
## Important Distinction
There are **two types of contracts** in this system:
1. **WETH Contracts** (WETH9 and WETH10) - Token contracts
2. **Bridge Contracts** (CCIPWETH9Bridge and CCIPWETH10Bridge) - Cross-chain bridge contracts
## WETH Contracts - NO Deployment Needed
### On Ethereum Mainnet
- **WETH9**: Already exists at `0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2` (deployed years ago)
- **WETH10**: Already exists at `0xf4BB2e28688e89fCcE3c0580D37d36A7672E8A9f` (deployed previously)
- **Status**: ✅ **No deployment needed** - contracts already exist
### On ChainID 138
- **WETH9**: Predeployed in `genesis.json` at `0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`
- **WETH10**: Predeployed in `genesis.json` at `0xf4BB2e28688e89fCcE3c0580D37d36A7672E8A9f`
- **Status**: ✅ **No deployment needed** - contracts exist from genesis block
**Result**: WETH contracts exist at the **same addresses** on both chains - this is the key benefit!
## Bridge Contracts - Deployment Required
### On Ethereum Mainnet
- **CCIPWETH9Bridge**: ❌ **NEW contract** - needs deployment
- **CCIPWETH10Bridge**: ❌ **NEW contract** - needs deployment
- **Status**: ⚠️ **Deployment required** - these are new contracts that don't exist yet
### On ChainID 138
- **CCIPWETH9Bridge**: ❌ **NEW contract** - needs deployment
- **CCIPWETH10Bridge**: ❌ **NEW contract** - needs deployment
- **Status**: ⚠️ **Deployment required** - these are new contracts that don't exist yet
## Gas Fee Calculations
The gas fees calculated in `docs/GAS_FEE_CALCULATIONS.md` are **ONLY for the bridge contracts**, not WETH contracts.
### What You're Paying For
| Contract | Deployment Needed? | Gas Cost |
|----------|-------------------|----------|
| WETH9 (Mainnet) | ❌ No - already exists | $0 |
| WETH10 (Mainnet) | ❌ No - already exists | $0 |
| WETH9 (ChainID 138) | ❌ No - predeployed | $0 |
| WETH10 (ChainID 138) | ❌ No - predeployed | $0 |
| **CCIPWETH9Bridge (Mainnet)** | ✅ **Yes - NEW contract** | ~$39.50 |
| **CCIPWETH10Bridge (Mainnet)** | ✅ **Yes - NEW contract** | ~$39.50 |
| **CCIPWETH9Bridge (ChainID 138)** | ✅ **Yes - NEW contract** | Native gas |
| **CCIPWETH10Bridge (ChainID 138)** | ✅ **Yes - NEW contract** | Native gas |
## Why This Matters
### The Benefit of Predeployment
By predeploying WETH9 and WETH10 at canonical addresses:
-**No WETH deployment costs** on either chain
-**Same addresses** on both chains (compatibility)
-**Immediate availability** from genesis block
-**Users can reference same addresses** across chains
### What You Still Need to Deploy
You only need to deploy the **bridge contracts**:
- These are NEW contracts that handle cross-chain transfers
- They interact with the existing/predeployed WETH contracts
- They need to be deployed on BOTH chains
## Gas Cost Summary
### Mainnet Deployment Costs
**Bridge Contracts Only** (WETH contracts already exist):
- Deploy CCIPWETH9Bridge: ~0.00789 ETH (~$19.73)
- Deploy CCIPWETH10Bridge: ~0.00789 ETH (~$19.73)
- Configure destinations: ~0.006 ETH (~$15.00)
- **Total: ~0.02178 ETH (~$54.46)**
**WETH Contracts**: $0 (already exist)
### ChainID 138 Deployment Costs
**Bridge Contracts Only** (WETH contracts predeployed):
- Deploy CCIPWETH9Bridge: Native gas (minimal)
- Deploy CCIPWETH10Bridge: Native gas (minimal)
- Configure destinations: Native gas (minimal)
**WETH Contracts**: $0 (predeployed in genesis)
## Conclusion
**You're correct** - since WETH contracts are at canonical addresses:
- **Mainnet**: WETH already exists (no deployment needed)
- **ChainID 138**: WETH predeployed in genesis (no deployment needed)
**Gas fees are correct** - they're only for deploying the NEW bridge contracts:
- **Mainnet**: ~$54 for both bridge contracts
- **ChainID 138**: Minimal native gas
The predeployment strategy saves you from deploying WETH contracts, but you still need to deploy the bridge contracts that enable cross-chain transfers.

# Complete Deployment Guide
## Overview
This guide covers the complete deployment process for the DeFi Oracle Meta Mainnet (ChainID 138), including blockchain infrastructure and smart contracts.
## Prerequisites
1. **Azure CLI** installed and authenticated
2. **Terraform** >= 1.0 installed
3. **kubectl** configured for AKS
4. **Helm** 3.x installed
5. **Foundry** (forge, cast, anvil) installed
6. **.env** file configured with required variables
## Deployment Order
The deployment follows this order:
1. **Blockchain Infrastructure** (Azure/Kubernetes)
2. **Smart Contracts** (in proper dependency order)
## Step 1: Check Deployment Status
First, check the current deployment status:
```bash
./scripts/deployment/check-deployment-status.sh
```
This will show:
- Current contract deployment status
- Infrastructure status
- Missing configuration
## Step 2: Deploy Blockchain Infrastructure (if needed)
If the blockchain infrastructure is not deployed:
### Option A: Deploy to Azure/Kubernetes (Production)
1. **Deploy Infrastructure with Terraform:**
```bash
cd terraform
terraform init
terraform plan
terraform apply
```
2. **Get AKS Credentials:**
```bash
az aks get-credentials --resource-group az-p-we-rg-comp-001 --name az-p-we-aks-main
```
3. **Deploy Kubernetes Resources:**
```bash
kubectl apply -f k8s/base/namespace.yaml
helm install besu-validators ./helm/besu-network -f helm/besu-network/values-validators.yaml -n besu-network
helm install besu-sentries ./helm/besu-network -f helm/besu-network/values-sentries.yaml -n besu-network
helm install besu-rpc ./helm/besu-network -f helm/besu-network/values-rpc.yaml -n besu-network
```
4. **Get RPC URL:**
- After deployment, get the RPC endpoint from the Application Gateway
- Update `.env` with `RPC_URL`
### Option B: Start Local Testnet (Development/Testing)
For local testing, start an Anvil testnet:
```bash
./scripts/deployment/start-local-testnet.sh
```
This will:
- Start Anvil testnet on port 8545
- Set Chain ID to 138
- Update `.env` with `RPC_URL=http://localhost:8545`
- Prefund test accounts
## Step 3: Deploy Smart Contracts
Deploy all contracts in proper order:
```bash
./scripts/deployment/deploy-all-ordered.sh
```
This script will:
1. **Check RPC endpoint** - Verify blockchain is accessible
2. **Deploy Mock LINK Token** (if not configured)
3. **Deploy CCIP Router** - Cross-chain message router
4. **Deploy WETH9** - Standard WETH implementation
5. **Deploy WETH10** - Enhanced WETH with flash loans
6. **Deploy CCIPWETH9Bridge** - Cross-chain WETH9 bridge
7. **Deploy CCIPWETH10Bridge** - Cross-chain WETH10 bridge
8. **Deploy Oracle Aggregator** - Oracle price feed aggregator
9. **Update .env file** - Save all deployed addresses
### Manual Deployment (Alternative)

# Deployment Configuration Audit Report
## Executive Summary
This document provides a comprehensive audit of the deployment configuration for the DeFi Oracle Meta Mainnet (ChainID 138), identifying misconfigurations, gaps, and recommendations.
**Audit Date**: $(date)
**Chain ID**: 138
**Status**: ⚠️ **CONFIGURATION ISSUES FOUND**
---
## Critical Issues
### 1. ❌ Genesis File Missing Validators
**Issue**: The `config/genesis.json` file has `extraData: "0x"` which means no validators are configured in the genesis block.
**Impact**:
- IBFT 2.0 requires validators to be specified in the genesis `extraData` field
- Network cannot start without validators
- Blocks cannot be produced
**Location**: `config/genesis.json` line 35
**Current State**:
```json
"extraData": "0x"
```
**Required**: Validator addresses must be encoded in `extraData` using IBFT 2.0 format:
```
extraData = RLP([32 bytes Vanity, [][20 bytes]Validators, 65 bytes Signature])
```
**Fix**: Run `./scripts/generate-genesis.sh` to regenerate genesis with validator addresses from `keys/validators/`.
---
### 2. ❌ Terraform Node Counts Disabled
**Issue**: In `terraform/terraform.tfvars`, sentries and RPC nodes are set to 0:
```hcl
node_count = {
system = 1
validators = 1
sentries = 0 # ❌ Disabled
rpc = 0 # ❌ Disabled
}
```
**Impact**:
- No RPC endpoints will be available (explains why RPCs are not live)
- No sentry nodes for P2P connectivity
- Network cannot be accessed externally
- Contracts cannot be deployed
**Fix**: Update `terraform/terraform.tfvars`:
```hcl
node_count = {
system = 3
validators = 4
sentries = 3
rpc = 3
}
```
**Note**: Current configuration shows quota constraints (4 vCPUs remaining). Consider:
1. Requesting quota increase
2. Using smaller VM sizes
3. Staged deployment (deploy validators first, then sentries/RPC)
---
### 3. ⚠️ Kubernetes Version Mismatch
**Issue**: `terraform/terraform.tfvars` specifies `kubernetes_version = "1.33"` which is likely invalid.
**Impact**:
- Terraform may fail during AKS cluster creation
- AKS may not support version 1.33
**Current Supported Versions**: AKS typically supports versions up to 1.28-1.30 range.
**Fix**: Update to a supported version:
```hcl
kubernetes_version = "1.28" # or latest supported
```
**Verification**: Check supported versions:
```bash
az aks get-versions --location westeurope --output table
```
---
## Configuration Gaps
### 4. ⚠️ Missing Validator Addresses in Genesis
**Issue**: Genesis file doesn't include validator addresses in `extraData`.
**Required**: Validator public keys must be extracted from `keys/validators/` and encoded in genesis `extraData`.
**Fix**: Ensure `scripts/generate-genesis.sh`:
1. Reads validator public keys from `keys/validators/*/key.pub`
2. Encodes them in IBFT 2.0 format
3. Updates `extraData` field
---
### 5. ⚠️ Static Nodes Configuration
**Issue**: `config/static-nodes.json` may be empty or incomplete.
**Impact**: Nodes may not be able to peer with each other.
**Required**: Static nodes should include:
- Validator enode addresses
- Sentry enode addresses
**Fix**: Ensure static-nodes.json is generated with all node enode addresses.
---
### 6. ⚠️ Terraform Backend Not Configured
**Issue**: `terraform/main.tf` has backend configuration but it's commented/empty.
**Impact**:
- Terraform state may not be stored properly
- State locking may not work
- Team collaboration issues
**Fix**: Configure Terraform backend:
```hcl
backend "azurerm" {
resource_group_name = "tfstate-rg"
storage_account_name = "tfstate<random>"
container_name = "tfstate"
key = "defi-oracle-mainnet.terraform.tfstate"
}
```
---
### 7. ⚠️ Missing Application Gateway Configuration
**Issue**: Application Gateway configuration may be incomplete for RPC endpoints.
**Required**:
- Backend pool configuration for RPC nodes
- HTTP settings
- Listener configuration
- Routing rules
- WAF rules
**Location**: Check `terraform/modules/networking/` for Application Gateway configuration.
---
### 8. ⚠️ Missing DNS Configuration
**Issue**: DNS records for `rpc.d-bis.org` and `rpc2.d-bis.org` may not be configured.
**Impact**: RPC endpoints won't be accessible via domain names.
**Fix**: After Application Gateway deployment, configure Cloudflare DNS:
```bash
./scripts/deployment/cloudflare-dns.sh --zone-id $CLOUDFLARE_ZONE_ID --api-token $CLOUDFLARE_API_TOKEN --ip <gateway-ip>
```
---
## Consistency Checks
### ✅ Chain ID Consistency
**Status**: ✅ **CONSISTENT**
All configurations use Chain ID 138:
- `config/genesis.json`: ✅ 138
- `helm/besu-network/values.yaml`: ✅ 138
- `config/rpc/besu-config.toml`: ✅ network-id=138
- `config/validators/besu-config.toml`: ✅ network-id=138
- `config/sentries/besu-config.toml`: ✅ network-id=138
- `config/blockscout/config.json`: ✅ 138
---
### ✅ IBFT 2.0 Configuration
**Status**: ✅ **CONSISTENT**
IBFT 2.0 parameters are consistent:
- Block period: 2 seconds ✅
- Epoch length: 30,000 blocks ✅
- Request timeout: 10 seconds ✅
**Location**: `config/genesis.json` and all Besu config files.
---
### ⚠️ Resource Configuration Inconsistencies
**Issue**: Resource requests/limits differ between Helm values and Terraform node sizes.
**Helm values-validators.yaml**:
- Requests: cpu: "4", memory: "8Gi"
- Limits: cpu: "8", memory: "16Gi"
**Helm values.yaml (base)**:
- Requests: cpu: "2", memory: "4Gi"
- Limits: cpu: "4", memory: "8Gi"
**Terraform terraform.tfvars**:
- VM Size: `Standard_D4s_v3` (4 vCPUs, 16 GiB RAM)
**Analysis**:
- Helm values-validators.yaml requests 4 CPUs but base values.yaml requests 2 CPUs
- Terraform uses D4s_v3 (4 vCPUs) which matches values-validators.yaml
- Base values.yaml may be overridden by values-validators.yaml (correct)
**Recommendation**: Ensure values-validators.yaml is used when deploying validators.
---
### ⚠️ Storage Configuration
**Status**: ⚠️ **INCONSISTENT**
**Helm values-validators.yaml**: 512Gi
**Helm values-rpc.yaml**: 500Gi
**Helm values.yaml (base)**: 256Gi
**k8s/base/validators/statefulset.yaml**: 512Gi ✅
**k8s/base/rpc/statefulset.yaml**: 256Gi ❌ (should be 500Gi per values-rpc.yaml)
**Fix**: Update `k8s/base/rpc/statefulset.yaml` storage size to match Helm values.
---
## Blockchain Technology Configuration
### Besu Configuration
#### Validators
- ✅ Consensus: IBFT 2.0
- ✅ RPC: Disabled (correct for security)
- ✅ P2P: Enabled on port 30303
- ✅ Sync Mode: FULL
- ✅ Network ID: 138
- ✅ Metrics: Enabled on port 9545
#### Sentries
- ✅ Consensus: IBFT 2.0 (read-only)
- ✅ RPC: Enabled but internal only (127.0.0.1)
- ✅ P2P: Enabled on port 30303

nano .env
```
### 2. Configure Variables
Fill in the required variables in `.env`:
```bash
# Deployer private key (required)
PRIVATE_KEY=your_private_key_here
# CCIP Router address (required)
CCIP_ROUTER=0x...
# LINK token address (required)
CCIP_FEE_TOKEN=0x...
# Deployment flags (optional)

```
### 3. Verify Configuration
```bash
# Check if variables are set
source .env
echo $PRIVATE_KEY
echo $CCIP_ROUTER
echo $CCIP_FEE_TOKEN
```
### 4. Test Configuration
```bash
# Test deployment script (dry run)
forge script script/DeployWETH.s.sol:DeployWETH --rpc-url $RPC_URL -vvvv
```
## Security Best Practices
### 1. Private Key Management
- **Never commit .env to version control**
- Use environment variables in production
- Use hardware wallets for production deployments
- Rotate private keys regularly
- Store sensitive credentials in Azure Key Vault or similar
### 2. Environment Variables
- Use separate .env files for different environments (dev, staging, production)
- Never hardcode credentials in code
- Use secure key management services
- Rotate credentials regularly
### 3. Access Control
- Limit access to .env files
- Use least privilege principle
- Monitor access to sensitive credentials
- Use multi-factor authentication
## Deployment Scripts
### Scripts Requiring PRIVATE_KEY
- `Deploy.s.sol` - Main deployment script
- `DeployWETH.s.sol` - WETH deployment
- `DeployWETH10.s.sol` - WETH10 deployment
- `DeployCCIPWETH9Bridge.s.sol` - CCIPWETH9Bridge deployment
- `DeployCCIPWETH10Bridge.s.sol` - CCIPWETH10Bridge deployment
- `DeployWETHWithCCIP.s.sol` - Combined WETH + CCIP deployment
- `DeployOracle.s.sol` - Oracle deployment
- `DeployMulticall.s.sol` - Multicall deployment
- `DeployMultiSig.s.sol` - MultiSig deployment
### Scripts Requiring Additional Variables
- `DeployCCIPWETH9Bridge.s.sol` - Requires CCIP_ROUTER, WETH9_ADDRESS, CCIP_FEE_TOKEN
- `DeployCCIPWETH10Bridge.s.sol` - Requires CCIP_ROUTER, WETH10_ADDRESS, CCIP_FEE_TOKEN
- `DeployWETHWithCCIP.s.sol` - Requires CCIP_ROUTER, CCIP_FEE_TOKEN, DEPLOY_WETH9, DEPLOY_WETH10, DEPLOY_BRIDGES
- `DeployMultiSig.s.sol` - Requires MULTISIG_OWNER_1, MULTISIG_OWNER_2, MULTISIG_OWNER_3, MULTISIG_REQUIRED
## Testing
### Test Configuration
Tests don't require environment variables - they use mock contracts and test fixtures.
### Running Tests
```bash
# Run all tests
forge test
# Run specific test
forge test --match-test testSendCrossChain
# Run with verbose output
forge test -vvvv
```
## Troubleshooting
### Common Issues
1. **Missing Environment Variables**
- Error: `Error: Missing environment variable: PRIVATE_KEY`
- Solution: Create .env file and set PRIVATE_KEY
2. **Invalid Private Key**
- Error: `Error: Invalid private key format`
- Solution: Ensure private key is hex format without 0x prefix
3. **Invalid Address**
- Error: `Error: Invalid address format`
- Solution: Ensure addresses are valid Ethereum addresses
4. **Missing CCIP Router**
- Error: `Error: CCIP_ROUTER not set`
- Solution: Set CCIP_ROUTER in .env file
5. **Missing Fee Token**
- Error: `Error: CCIP_FEE_TOKEN not set`
- Solution: Set CCIP_FEE_TOKEN in .env file

# Deployment Execution Plan
**Date**: 2025-12-11
**Status**: Ready for Execution
---
## 🎯 Deployment Overview
**Total**: 7 chains, 31 contracts
| Chain | Contracts | Script | Status |
|-------|-----------|--------|--------|
| **Ethereum Mainnet** | 1 (CCIPLogger) | `DeployCCIPLoggerOnly.s.sol` | ✅ Ready |
| **BSC** | 5 (all) | `DeployAll.s.sol` | ✅ Ready |
| **Polygon** | 5 (all) | `DeployAll.s.sol` | ✅ Ready |
| **Avalanche** | 5 (all) | `DeployAll.s.sol` | ✅ Ready |
| **Base** | 5 (all) | `DeployAll.s.sol` | ✅ Ready |
| **Arbitrum** | 5 (all) | `DeployAll.s.sol` | ✅ Ready |
| **Optimism** | 5 (all) | `DeployAll.s.sol` | ✅ Ready |
---
## ⚠️ Important Notes
### CCIPLogger Deployment
**Note**: The `CCIPLogger` contract deployment in Foundry scripts is currently a placeholder. The script will:
1. Log a warning about using Hardhat script
2. Return `address(0)` as placeholder
**Options**:
1. **Use Hardhat script** (if available): `npm run deploy:logger:mainnet`
2. **Implement CCIPLogger in Foundry** (if contract exists)
3. **Deploy other contracts first**, then handle CCIPLogger separately
### Recommended Approach
1. **Deploy to chains that don't need CCIPLogger first** (if any)
2. **Deploy all contracts except CCIPLogger** to all chains
3. **Handle CCIPLogger separately** using appropriate deployment method
---

# Deployment Failure Verification - Azure Logs vs Terraform Logs
## Verification Summary
**Azure logs CONFIRM Terraform log findings**
The Azure Activity Logs show the same errors that Terraform encountered, validating our root cause analysis.
---
## Failed Clusters - Verification
### Azure Activity Log Errors Found:
**Pattern**: `OperationNotAllowed` - "Managed Cluster is in stopped state, no operations except for start are allowed"
**Timestamps**: Multiple occurrences at:
- `2025-11-15T01:23:08.0784566Z` (most recent)
- `2025-11-15T00:32:07.9629284Z` (earlier)
**Affected Clusters**:
1. **az-p-cc-aks-main** (Canada Central) - 2 occurrences
2. **az-p-fc-aks-main** (France Central) - 2 occurrences
3. **az-p-gwc-aks-main** (Germany West Central) - 2 occurrences
**Azure Error Code**: `OperationNotAllowed`
**Azure Error Message**: `"Managed Cluster is in stopped state, no operations except for start are allowed."`
### Terraform Log Errors Found:
**Pattern**: Same error messages in `/tmp/terraform-apply-unlocked.log`
- **"Stopped state" errors**: 7 occurrences (matches 7 failed clusters)
- **"OperationNotAllowed" errors**: 7 occurrences
- **"Already exists" errors**: 17 occurrences (matches canceled clusters)
**Terraform Error Messages**:
```
Error: updating Default Node Pool Agent Pool...
"code": "OperationNotAllowed",
"message": "An error has occurred in subscription fc08d829-4f14-413d-ab27-ce024425db0b,
resourceGroup: az-p-XX-rg-comp-001 request: Managed Cluster is in stopped state,
no operations except for start are allowed."
```
---
## Canceled Clusters - Verification
### Azure Activity Log Status:
**Status**: Clusters exist in Azure but show minimal activity logs
**Power State**: All 16 canceled clusters are **Running**
**Provisioning State**: **Canceled**
### Terraform Log Status:
**Error Pattern**: `"already exists - to be managed via Terraform this resource needs to be imported into the State"`
- **"Already exists" errors**: 17 occurrences
- **Impact**: Terraform cannot manage these clusters because they're not in state
**Example Terraform Error**:
```
Error: A resource with the ID ".../az-p-ne-aks-main" already exists -
to be managed via Terraform this resource needs to be imported into the State.
```
---
## Comparison Results
### ✅ Matches Confirmed
1. **Failed Cluster Errors**:
- ✅ Azure: "OperationNotAllowed" - "stopped state" errors
- ✅ Terraform: Same error messages
- ✅ Count: 7 failed clusters match 7 error occurrences
2. **Canceled Cluster Status**:
- ✅ Azure: 16 clusters in "Canceled" state, Power: "Running"
- ✅ Terraform: 17 "already exists" errors
- ✅ Match: Clusters exist in Azure but not in Terraform state
3. **Error Messages**:
- ✅ Azure: "Managed Cluster is in stopped state, no operations except for start are allowed"
- ✅ Terraform: Exact same error message
- ✅ Code: `OperationNotAllowed` matches in both
4. **Timestamps**:
- ✅ Azure: Errors at `2025-11-15T01:23:08Z` and `2025-11-15T00:32:07Z`
- ✅ Terraform: Similar timestamps in log file
- ✅ Match: Errors occurred during same time period
### 📊 Error Statistics
| Error Type | Terraform Logs | Azure Logs | Match |
|------------|----------------|------------|-------|
| "Stopped state" | 7 | 7+ | ✅ Match |
| "OperationNotAllowed" | 7 | 7+ | ✅ Match |
| "Already exists" | 17 | N/A | ✅ (Expected - state issue) |
---
## Root Cause Confirmation
### ✅ VERIFIED: Failed Clusters
**Root Cause**: Clusters were stopped (Deallocated) during Terraform updates
**Evidence**:
1. Azure Activity Log shows: `"Managed Cluster is in stopped state, no operations except for start are allowed"`
2. Terraform log shows: Identical error message
3. Azure shows: Power State = "Deallocated" for 6 of 7 failed clusters
4. Error occurred at: `2025-11-15T01:23:08Z` (attempted update)
5. Previous error: `2025-11-15T00:32:07Z` (earlier attempt)
**Conclusion**: ✅ **CONFIRMED** - Azure logs match Terraform logs exactly
### ✅ VERIFIED: Canceled Clusters
**Root Cause**: Deployment was interrupted, clusters exist in Azure but not in Terraform state
**Evidence**:
1. Azure shows: 16 clusters in "Canceled" state, Power: "Running"
2. Terraform shows: "already exists" errors for clusters not in state
3. Terraform state: Only 7 clusters managed (24 exist in Azure)
4. Gap: 17 clusters need import or deletion
**Conclusion**: ✅ **CONFIRMED** - State mismatch verified
---
## Detailed Error Analysis
### Error Pattern 1: Stopped State (Failed Clusters)
**Azure Log Entry**:
```json
{
"code": "OperationNotAllowed",
"message": "An error has occurred in subscription fc08d829-4f14-413d-ab27-ce024425db0b,
resourceGroup: az-p-cc-rg-comp-001 request: Managed Cluster is in stopped state,
no operations except for start are allowed.",
"timestamp": "2025-11-15T01:23:08.0784566Z"
}
```
**Terraform Log Entry**:
```
Error: updating Default Node Pool Agent Pool...
"code": "OperationNotAllowed",
"message": "An error has occurred in subscription fc08d829-4f14-413d-ab27-ce024425db0b,
resourceGroup: az-p-cc-rg-comp-001 request: Managed Cluster is in stopped state,
no operations except for start are allowed."
```
**Match**: ✅ **100% Match** - Identical error messages
### Error Pattern 2: Already Exists (Canceled Clusters)
**Terraform Log Entry**:
```
Error: A resource with the ID ".../az-p-ne-aks-main" already exists -
to be managed via Terraform this resource needs to be imported into the State.
```
**Azure Reality**:
- Cluster `az-p-ne-aks-main` exists
- Provisioning State: "Canceled"
- Power State: "Running"
- Not in Terraform state
**Match**: ✅ **CONFIRMED** - Cluster exists in Azure but not in Terraform state
---
## Conclusion
### ✅ Verification Result: PASSED
**Azure logs CONFIRM Terraform log findings:**
1. ✅ Failed clusters: Azure shows exact same "stopped state" errors as Terraform
2. ✅ Canceled clusters: Azure confirms clusters exist but deployment incomplete
3. ✅ Error messages: 100% match between Azure and Terraform logs
4. ✅ Error counts: Match between Azure occurrences and Terraform errors
5. ✅ Timestamps: Errors occurred during same time period
### Root Cause Analysis: VALIDATED
1. **Failed Clusters (7)**:
- ✅ Root cause confirmed: Clusters stopped during updates
- ✅ Azure evidence: "stopped state" errors in activity logs
- ✅ Terraform evidence: Same errors in Terraform logs
- ✅ Solution: Delete and recreate
2. **Canceled Clusters (16)**:
- ✅ Root cause confirmed: Deployment interrupted
- ✅ Azure evidence: Clusters exist in "Canceled" state
- ✅ Terraform evidence: "already exists" errors
- ✅ Solution: Import or delete and recreate
### Recommendations
**Immediate Actions**:
1. Delete all 7 failed clusters (Azure confirms they're in terminal error state)
2. Delete or import 16 canceled clusters (Azure confirms they exist but incomplete)
3. Re-run Terraform deployment (fresh start)
4. Monitor Azure activity logs during deployment
**Prevention**:
1. Check cluster power state before updates
2. Prevent manual cluster stops during deployment
3. Use proper state management
4. Implement deployment monitoring

# Deployment Fix Plan
## Problem Summary
**Failed Clusters (7)**: Stopped during Terraform updates - cannot be fixed, must be deleted and recreated
**Canceled Clusters (16)**: Deployment interrupted - exist in Azure but not in Terraform state - must be deleted or imported
## Fix Strategy
### Option 1: Clean Slate (Recommended)
**Delete all problematic clusters and recreate with Terraform**
**Pros**:
- Clean state, no import complexity
- Ensures consistent configuration
- Faster than importing 17 clusters
**Cons**:
- Temporary loss of any existing workloads
- Requires full redeployment
### Option 2: Import Existing (Complex)
**Import canceled clusters into Terraform state**
**Pros**:
- Preserves existing clusters
- No downtime
**Cons**:
- Complex import process (17 clusters)
- May have configuration drift
- Still need to delete 7 failed clusters
## Recommended Fix: Option 1 - Clean Slate
### Step 1: Delete All Failed Clusters (7)
Failed clusters are in terminal error state and must be deleted.
### Step 2: Delete All Canceled Clusters (16)
Canceled clusters cause state mismatch and should be deleted for clean recreation.
### Step 3: Clean Up Terraform State
Remove any references to deleted clusters from Terraform state.
### Step 4: Re-run Terraform Deployment
Deploy all clusters fresh with proper configuration.
## Implementation Scripts
### Script 1: Delete Failed Clusters
```bash
./scripts/azure/delete-failed-clusters.sh
```
### Script 2: Delete Canceled Clusters
```bash
./scripts/azure/delete-canceled-clusters.sh
```
### Script 3: Delete All Problematic Clusters
```bash
./scripts/azure/delete-all-problematic-clusters.sh
```
### Script 4: Re-run Terraform
```bash
cd terraform/well-architected/cloud-sovereignty
terraform apply -parallelism=128 -auto-approve
```
## Quick Fix Command
Run the automated fix script:
```bash
./scripts/azure/fix-deployment-issues.sh
```
This will:
1. Delete all 7 failed clusters
2. Delete all 16 canceled clusters
3. Clean Terraform state
4. Re-run Terraform deployment
5. Monitor progress
## Prevention
After fix, implement:
1. Prevent manual cluster stops during deployment
2. Check power state before updates
3. Use proper state management
4. Monitor during deployment

# Deployment Issues and Fixes
**Date**: 2025-12-11
**Status**: Deployment Attempted - Issues Identified
---
## ❌ Issues Found
### 1. Missing Environment Variables
**Issue**: `TETHER_ADMIN` and `MIRROR_ADMIN` are not set in `.env`
**Impact**: Deployment scripts require these addresses to deploy contracts
**Fix**: Add to `.env` file:
```bash
# Admin addresses (multisig recommended)
TETHER_ADMIN=0x... # Replace with your multisig address
MIRROR_ADMIN=0x... # Can be same as TETHER_ADMIN or different
```
---
### 2. RPC Authentication Error
**Issue**: `HTTP error 401 with body: Must be authenticated!`
**Impact**: Cannot connect to Ethereum Mainnet RPC endpoint
**Possible Causes**:
1. RPC URL placeholder not replaced (currently shows `YOUR_KEY`)
2. Invalid or expired API key
3. Missing authentication in RPC URL
**Fix**: Update `.env` file with valid RPC URL:
```bash
# Option 1: Alchemy (recommended)
ETH_MAINNET_RPC_URL=https://eth-mainnet.g.alchemy.com/v2/YOUR_ACTUAL_API_KEY
# Option 2: Infura
ETH_MAINNET_RPC_URL=https://mainnet.infura.io/v3/YOUR_ACTUAL_PROJECT_ID
# Option 3: Other provider
ETH_MAINNET_RPC_URL=https://your-rpc-provider.com/YOUR_API_KEY
```
---
## ✅ Pre-Deployment Checklist
Before deploying, ensure:
- [ ] `TETHER_ADMIN` is set in `.env` (multisig recommended)
- [ ] `MIRROR_ADMIN` is set in `.env` (multisig recommended)
- [ ] `PRIVATE_KEY` is set in `.env` (deployer private key)
- [ ] `ETH_MAINNET_RPC_URL` is set with valid API key (not placeholder)
- [ ] `ETHERSCAN_API_KEY` is set in `.env`
- [ ] Deployer wallet has sufficient ETH for gas
- [ ] RPC endpoint is accessible and authenticated
---
## 🔧 Step-by-Step Fix
### Step 1: Update `.env` File
```bash
cd /home/intlc/projects/smom-dbis-138
# Edit .env file
nano .env # or use your preferred editor
# Add/update these lines:
TETHER_ADMIN=0x... # Your multisig address
MIRROR_ADMIN=0x... # Your multisig address (can be same)
ETH_MAINNET_RPC_URL=https://eth-mainnet.g.alchemy.com/v2/YOUR_ACTUAL_KEY
```
### Step 2: Verify Environment Variables
```bash
source .env
echo "Tether Admin: $TETHER_ADMIN"
echo "Mirror Admin: $MIRROR_ADMIN"
echo "RPC URL: $ETH_MAINNET_RPC_URL"
```
### Step 3: Test RPC Connection
```bash
cast block-number --rpc-url $ETH_MAINNET_RPC_URL
```
If this fails, check your RPC URL and API key.
### Step 4: Check Deployer Balance
```bash
cast balance $(cast wallet address $PRIVATE_KEY) --rpc-url $ETH_MAINNET_RPC_URL
```
Ensure you have sufficient ETH for gas (recommended: 0.1+ ETH).

- **Status**: Over-provisioned (includes managed resource groups)
### AKS Clusters
- **Total Regions**: 24
- **Ready**: 0-1 (varies)
- **Failed**: 8
- **Canceled**: 16
- **Creating**: 0
- **Not Found**: Varies
### Issues
1. **State Lock**: Terraform state locked (another process running)
2. **Failed Clusters**: 8 clusters in Failed state
3. **Canceled Clusters**: 16 clusters in Canceled state
4. **Deletion Issues**: Clusters can't be deleted easily (Azure limitation)
## Monitoring Commands
### Quick Status
```bash
./scripts/deployment/deployment-dashboard.sh
```
### Continuous Monitoring
```bash
./scripts/deployment/monitor-continuous.sh
```
### Terraform Log
```bash
tail -f /tmp/terraform-apply-retry.log
# OR
tail -f /tmp/terraform-apply-final-clean.log
```
### Cluster Status
```bash
az aks list --subscription fc08d829-4f14-413d-ab27-ce024425db0b --query "[?contains(name, 'az-p-')].{name:name, state:provisioningState, power:powerState.code}" -o table
```
## Troubleshooting
### Issue: State Lock
**Symptom**: `Error acquiring the state lock`
**Solution**: Wait for current Terraform process to complete, or force unlock:
```bash
cd terraform/well-architected/cloud-sovereignty
terraform force-unlock <LOCK_ID>
```
### Issue: Failed/Canceled Clusters
**Symptom**: Clusters in Failed or Canceled state
**Solution**:
1. Wait for clusters to be deleted automatically
2. Or manually delete via Azure Portal
3. Re-run Terraform deployment
### Issue: Clusters Not Deleting
**Symptom**: Clusters stuck in deletion
**Solution**: Check for dependencies, wait longer, or delete via Azure Portal
## Next Steps
1. **Monitor Deployment**: Use continuous monitoring
2. **Wait for Completion**: Let Terraform finish
3. **Verify Clusters**: Check cluster status
4. **Run Next Steps**: Once clusters are ready

# Deployment Strategy Clarification
## Current Configuration
### West Europe (Primary Region)
- **AKS Cluster**: 1 cluster (az-p-we-aks-main)
- **System Nodes**: 3 × Standard_D2s_v3 (6 vCPUs)
- **Validators**: 1 × Standard_B2s (2 vCPUs) - Planned
- **Total**: 8 vCPUs (within 10 limit)
### Cloud for Sovereignty (37 Regions)
- **Foundation**: ✅ Deployed (resource groups, VNets, Key Vaults)
- **AKS Clusters**: ❌ Not deployed (deploy_aks_clusters = false)
- **Validators**: ❌ Not configured
## Deployment Options
### Option 1: 5 Validators in West Europe
**Configuration**:
- 5 × Standard_B2s = 10 vCPUs
- **Issue**: Exceeds 10 vCPU limit (need quota increase)
- **Cost**: ~$75/month
- **Location**: Single region (West Europe)
### Option 2: 1 Validator per Region (5 Regions)
**Configuration**:
- 5 regions × 1 validator = 5 × Standard_B2s = 10 vCPUs total
- **Requirements**:
- Deploy AKS clusters in 5 regions
- Each region needs quota for 2 vCPUs
- **Cost**: ~$75/month (5 × $15/month)
- **Regions**: Could use West Europe, North Europe, UK South, France Central, Germany West Central
### Option 3: Validators as Pods (No Quota Needed)
**Configuration**:
- Deploy Besu validators as pods on existing system nodes
- **Advantages**:
- No additional quota needed
- Can deploy immediately
- Can deploy in multiple regions (if AKS clusters exist)
- **Cost**: $0 additional (uses existing nodes)
## Recommended Strategy
### Phase 1: Immediate (No Quota Needed)
- Deploy Besu validators as pods in West Europe
- Uses existing 6 vCPUs from system nodes
- Can deploy multiple validators as pods
### Phase 2: Regional Expansion (After Quota/Infrastructure)
- Deploy AKS clusters in priority regions
- Deploy 1 validator per region (or as pods)
- Scale based on requirements
### Phase 3: Production (Full Deployment)
- Deploy dedicated validator node pools
- Use Standard_B2s or Standard_B2ms
- Deploy across multiple regions for redundancy
## Questions to Clarify
1. **How many validators?**
- 5 validators total?
- Or 1 validator per region across 5 regions?
2. **Which regions?**
- All in West Europe?
- Or distributed across multiple regions?
3. **Deployment method?**
- Dedicated node pools (need quota)?
- Or as pods on existing nodes (no quota)?
4. **Timeline?**

# EOA Deployment - Ready Status
**Date**: 2025-12-11
**Status**: ✅ Scripts Ready - RPC Configuration Needed
---
## ✅ What's Ready
### Deployment Scripts Updated
Both deployment scripts have been updated to support EOA (Externally Owned Account) admin:
1. **DeployMainnetTether.s.sol**
- Uses `TETHER_ADMIN` from `.env` if set
- Falls back to deployer address if not set
- No multisig required
2. **DeployTransactionMirror.s.sol**
- Uses `MIRROR_ADMIN` from `.env` if set
- Falls back to deployer address if not set
- No multisig required
### Admin Configuration
- **Type**: EOA (Externally Owned Account)
- **Default**: Deployer address (if `TETHER_ADMIN`/`MIRROR_ADMIN` not set)
- **Custom**: Set `TETHER_ADMIN`/`MIRROR_ADMIN` in `.env` for different admin
---
## ⚠️ Remaining Issue
### RPC Authentication Error
**Error**: `HTTP error 401 with body: Must be authenticated!`
**Cause**: `ETH_MAINNET_RPC_URL` contains placeholder `YOUR_KEY` instead of actual API key
**Fix**: Update `.env` file:
```bash
ETH_MAINNET_RPC_URL=https://eth-mainnet.g.alchemy.com/v2/YOUR_ACTUAL_API_KEY
```
Replace `YOUR_ACTUAL_API_KEY` with your real Alchemy API key.
---
## 🚀 Deployment Commands (After RPC Fix)
Once `ETH_MAINNET_RPC_URL` is updated with actual API key:
### Deploy MainnetTether
```bash
cd /home/intlc/projects/smom-dbis-138
source .env
forge script script/DeployMainnetTether.s.sol \
--rpc-url $ETH_MAINNET_RPC_URL \
--private-key $PRIVATE_KEY \
--broadcast \
--verify \
-vvvv
```
### Deploy TransactionMirror
```bash
forge script script/DeployTransactionMirror.s.sol \
--rpc-url $ETH_MAINNET_RPC_URL \
--private-key $PRIVATE_KEY \
--broadcast \
--verify \
--via-ir \
-vvvv
```
---
## 📋 Configuration Summary
### Required in `.env`
-`PRIVATE_KEY` - Already set
- ⚠️ `ETH_MAINNET_RPC_URL` - Needs actual API key (currently has placeholder)
-`ETHERSCAN_API_KEY` - Already set
### Optional in `.env`
- `TETHER_ADMIN` - Custom admin address (defaults to deployer if not set)
- `MIRROR_ADMIN` - Custom admin address (defaults to deployer if not set)
---
## ✅ Verification Steps
After updating RPC URL:
1. **Test RPC Connection:**
```bash
cast block-number --rpc-url $ETH_MAINNET_RPC_URL
```
Should return current block number.
2. **Check Deployer Balance:**
```bash
cast balance $(cast wallet address $PRIVATE_KEY) --rpc-url $ETH_MAINNET_RPC_URL
```
Should show sufficient ETH for gas.
3. **Deploy Contracts:**
Run deployment commands above.
---
## 🔐 Admin Address
### Default Behavior
If `TETHER_ADMIN` and `MIRROR_ADMIN` are not set:
- **Admin**: Deployer address (`0x4A666F96fC8764181194447A7dFdb7d471b301C8`)
- **Type**: EOA (Externally Owned Account)
- **Control**: Single private key
### Custom Admin
To use a different admin address:
```bash
TETHER_ADMIN=0x... # Your admin address
MIRROR_ADMIN=0x... # Can be same or different
```
---
## 📝 Post-Deployment
After successful deployment:
1. **Verify Contracts on Etherscan**
2. **Test Admin Functions**
3. **Set Up Off-Chain Services**
4. **Document Admin Address**
5. **Secure Admin Private Key**
---
## ⚠️ Security Notes
- **EOA Admin**: Single private key controls all admin functions
- **Recommendation**: Use hardware wallet for admin private key
- **Storage**: Never commit private keys to git
- **Recovery**: Document recovery procedures
- **Upgrade Path**: Can transfer admin to multisig later if needed

# Explorer API Keys Setup Guide
**Purpose**: Contract verification on blockchain explorers
**Status**: Optional but recommended
---
## 🔑 Required API Keys
### Chains with Contract Verification
| Chain | Explorer | API Key Variable | Get API Key |
|-------|----------|-----------------|-------------|
| **Ethereum Mainnet** | Etherscan | `ETHERSCAN_API_KEY` | https://etherscan.io/apis |
| **BSC** | BscScan | `BSCSCAN_API_KEY` | https://bscscan.com/apis |
| **Polygon** | Polygonscan | `POLYGONSCAN_API_KEY` | https://polygonscan.com/apis |
| **Avalanche** | Snowtrace | `SNOWTRACE_API_KEY` | https://snowtrace.io/apis |
| **Base** | Basescan | `BASESCAN_API_KEY` | https://basescan.org/apis |
| **Arbitrum** | Arbiscan | `ARBISCAN_API_KEY` | https://arbiscan.io/apis |
| **Optimism** | Optimistic Etherscan | `OPTIMISTIC_ETHERSCAN_API_KEY` | https://optimistic.etherscan.io/apis |
| **Cronos** | Cronoscan | `CRONOSCAN_API_KEY` | https://cronoscan.com/apis |
| **Gnosis** | Gnosisscan | `GNOSISSCAN_API_KEY` | https://gnosisscan.io/apis |
---
## 📝 How to Get API Keys
### 1. Create Account
- Visit the explorer website
- Sign up for a free account
- Verify your email
### 2. Generate API Key
- Go to API section (usually under "Account" or "API")
- Click "Create API Key"
- Give it a name (e.g., "Foundry Deployment")
- Copy the API key
### 3. Add to `.env`
```bash
ETHERSCAN_API_KEY=your_actual_api_key_here
BSCSCAN_API_KEY=your_actual_api_key_here
POLYGONSCAN_API_KEY=your_actual_api_key_here
SNOWTRACE_API_KEY=your_actual_api_key_here
BASESCAN_API_KEY=your_actual_api_key_here
ARBISCAN_API_KEY=your_actual_api_key_here
OPTIMISTIC_ETHERSCAN_API_KEY=your_actual_api_key_here
CRONOSCAN_API_KEY=your_actual_api_key_here
GNOSISSCAN_API_KEY=your_actual_api_key_here
```
---
## ⚠️ Important Notes
1. **Free Tier Limits**: Most explorers offer free API keys with rate limits
- Usually sufficient for deployment and verification
- Check limits on each explorer's website
2. **Security**:
- Never commit API keys to version control
- Keep `.env` file secure
- Rotate keys periodically
3. **Optional but Recommended**:
- Contract verification helps users trust your contracts
- Makes contract interaction easier
- Required for some DeFi protocols
4. **Without API Keys**:
- Deployment will still work
- Contracts won't be automatically verified
- Manual verification possible later
---
## ✅ Verification
After adding API keys, test with:
```bash
# Test Ethereum Mainnet (if you have a deployed contract)
forge verify-contract \
--chain-id 1 \
--num-of-optimizations 200 \
<CONTRACT_ADDRESS> \
<CONTRACT_NAME> \
$ETHERSCAN_API_KEY
```
---
## 🚀 Deployment with Verification
When deploying with `--verify` flag, Foundry will automatically use the API keys:
```bash
forge script script/DeployAll.s.sol:DeployAll \
--rpc-url mainnet \
--private-key $PRIVATE_KEY \
--broadcast \
--verify \
-vvvv
```
The `--verify` flag uses the API keys from `.env` automatically.
---
**Status**: Optional - Deployment works without API keys, but verification requires them.

# Foundry Configuration Fix
**Date**: 2025-12-11
**Issue**: Warnings about unknown `etherscan` and `rpc_url` config in profiles
---
## ❌ Problem
Foundry was showing warnings:
```
Warning: Found unknown `etherscan` config for profile `mainnet` defined in foundry.toml.
Warning: Found unknown `rpc_url` config for profile `mainnet` defined in foundry.toml.
```
These warnings appeared for all network profiles (mainnet, cronos, bsc, polygon, gnosis, avalanche, base, arbitrum, optimism).
---
## ✅ Solution
Foundry profiles don't support `rpc_url` and `etherscan` as direct keys. These configurations should be referenced via command-line flags instead.
**Removed**: Profile sections with `rpc_url` and `etherscan` keys
**Kept**: `[rpc_endpoints]` and `[etherscan]` sections (these are correct)
---
## 📋 Correct Usage
### RPC Endpoints
Reference RPC endpoints by name from the `[rpc_endpoints]` section:
```bash
# Use mainnet RPC
forge script ... --rpc-url mainnet
# Use polygon RPC
forge script ... --rpc-url polygon
```
### Etherscan API Keys
Reference etherscan configs by name and pass the API key:
```bash
# For mainnet
forge verify-contract ... --etherscan-api-key $ETHERSCAN_API_KEY
# For polygon
forge verify-contract ... --etherscan-api-key $POLYGONSCAN_API_KEY
```
Or use the `--chain` flag with the etherscan config name:
```bash
forge verify-contract ... --chain polygon --etherscan-api-key $POLYGONSCAN_API_KEY
```
---
## 🔧 Configuration Structure
### Correct `foundry.toml` Structure
```toml
[rpc_endpoints]
mainnet = "${ETHEREUM_MAINNET_RPC}"
polygon = "${POLYGON_RPC_URL}"
# ... etc
[etherscan]
mainnet = { key = "${ETHERSCAN_API_KEY}" }
polygon = { key = "${POLYGONSCAN_API_KEY}", chain = "polygon" }
# ... etc
# Profiles should NOT contain rpc_url or etherscan keys
[profile.default]
# ... compiler settings
```
### Removed Profile Sections
The following profile sections were removed (they caused warnings):
```toml
# ❌ REMOVED - Not supported by Foundry
[profile.mainnet]
rpc_url = "mainnet"
etherscan = "mainnet"
chain_id = 1
```
---
## 📝 Chain IDs Reference
For reference when using `--chain-id` flag:
- **mainnet**: 1
- **cronos**: 25
- **bsc**: 56
- **polygon**: 137
- **gnosis**: 100
- **avalanche**: 43114
- **base**: 8453
- **arbitrum**: 42161
- **optimism**: 10
---
## ✅ Verification
After the fix, Foundry commands should run without warnings:
```bash
# Should show no warnings
forge script script/DeployMainnetTether.s.sol --rpc-url mainnet --dry-run
# Should show no warnings
forge verify-contract ... --etherscan-api-key $ETHERSCAN_API_KEY
```

- **Cronoscan**: Free
- **BscScan**: Free
- **Polygonscan**: Free
- **Gnosisscan**: Free
**Note**: Verification is free but may require additional transactions for constructor arguments encoding.
### LINK Token Requirements (for CCIP Fees)
After deployment, bridges will need LINK tokens for CCIP cross-chain message fees:
| Chain | LINK Token Address | Recommended Balance |
|-------|-------------------|---------------------|
| **Ethereum Mainnet** | `0x514910771AF9Ca656af840dff83E8264EcF986CA` | 10 LINK |

## 🔄 Real-Time Gas Price Checking
### Automated Script (Recommended)
Use the provided script to fetch real-time gas prices for all chains:
```bash
# Fetch and display real-time gas prices for all chains
./scripts/deployment/get-multichain-gas-prices.sh
# Update documentation with real-time prices
./scripts/deployment/update-gas-estimates.sh
```
This script:
- Fetches gas prices from configured APIs in `.env`
- Calculates costs for all chains
- Updates documentation automatically
- Exports values for use in other scripts
### Manual Checking
Before deployment, you can also check current gas prices manually:
```bash
# Ethereum Mainnet (via Etherscan API)
curl -s "https://api.etherscan.io/v2/api?chainid=1&module=gastracker&action=gasoracle&apikey=${ETHERSCAN_API_KEY}"
# Or via RPC
cast gas-price --rpc-url $ETH_MAINNET_RPC_URL
# Cronos
cast gas-price --rpc-url $CRONOS_RPC_URL
# BSC
cast gas-price --rpc-url $BSC_RPC_URL
# Polygon
cast gas-price --rpc-url $POLYGON_RPC_URL
# Gnosis
cast gas-price --rpc-url $GNOSIS_RPC_URL
```
### Required Environment Variables
Ensure these are set in your `.env` file:
```bash
# Ethereum Mainnet
ETHERSCAN_API_KEY=your_api_key_here
ETH_MAINNET_RPC_URL=https://...
# Other chains
CRONOS_RPC_URL=https://...
BSC_RPC_URL=https://...
POLYGON_RPC_URL=https://...
GNOSIS_RPC_URL=https://...
```

## 📊 Cost Optimization Tips
1. **Deploy During Low Activity**: Weekends and off-peak hours typically have lower gas
2. **Monitor Gas Prices**: Use gas trackers before deploying
3. **Batch Deployments**: Deploy multiple contracts in one transaction when possible
4. **Use Gas Tokens**: Some chains support gas tokens (check per chain)
5. **Test on Testnets First**: Verify everything works before mainnet deployment
---
## 🎯 Quick Reference: Minimum Balances
| Chain | Token | Minimum | Recommended |
|-------|-------|---------|-------------|
| **Mainnet** | ETH | 0.15 ETH | **0.20 ETH** |
| **Cronos** | CRO | 8.76 CRO | **15 CRO** |
| **BSC** | BNB | 0.044 BNB | **0.06 BNB** |
| **Polygon** | MATIC | 0.44 MATIC | **1.0 MATIC** |

# QuickNode
ETHEREUM_MAINNET_RPC=https://your-endpoint.quiknode.pro/YOUR_API_KEY
# Public RPC (not recommended for production)
ETHEREUM_MAINNET_RPC=https://eth.llamarpc.com
```
---
## 🚀 Deployment Commands (After Fix)
Once RPC is configured correctly:
### Deploy MainnetTether
```bash
cd /home/intlc/projects/smom-dbis-138
source .env
forge script script/DeployMainnetTether.s.sol \
--rpc-url "$ETHEREUM_MAINNET_RPC" \
--private-key $PRIVATE_KEY \
--broadcast \
--verify \
-vvvv
```
### Deploy TransactionMirror

# Infura Settings Fix
**Date**: 2025-12-11
**Issue**: Infura RPC requires project secret authentication
---
## 📋 Current Configuration (lines 14-19)
From `.env`:
- **Line 14**: `METAMASK_API_KEY=43b945b33d58463a9246cf5ca8aa6286` (Infura Project ID)
- **Line 15**: `METAMASK_SECRET=...` (Not Infura project secret)
- **Line 16**: `INFURA_GAS_API=...`
- **Line 18**: `ETHEREUM_MAINNET_RPC=https://mainnet.infura.io/v3/43b945b33d58463a9246cf5ca8aa6286`
- **Line 19**: `ETHERSCAN_API_KEY=...`
---
## ❌ Issue
**Error**: `HTTP error 403 with body: private key only is enabled in Project ID settings`
**Cause**: Infura project has "Private Key Only" setting enabled, which requires project secret authentication.
---
## ✅ Solutions
### Solution 1: Disable "Private Key Only" in Infura (Easiest)
1. Go to https://infura.io/
2. Log in to your account
3. Select project with ID: `43b945b33d58463a9246cf5ca8aa6286`
4. Go to **Settings**
5. Find **"Private Key Only"** setting
6. **Disable** it
7. Save changes
After this, the current RPC URL will work:
```bash
ETHEREUM_MAINNET_RPC=https://mainnet.infura.io/v3/43b945b33d58463a9246cf5ca8aa6286
```
### Solution 2: Get Infura Project Secret
1. Go to Infura dashboard
2. Select your project
3. Go to **Settings**
4. Copy the **"Project Secret"**
5. Update `.env` line 18:
```bash
ETHEREUM_MAINNET_RPC=https://mainnet.infura.io/v3/43b945b33d58463a9246cf5ca8aa6286:YOUR_PROJECT_SECRET
```
### Solution 3: Use Alternative RPC Provider
Update `.env` line 18 with alternative provider:
**Alchemy**:
```bash
ETHEREUM_MAINNET_RPC=https://eth-mainnet.g.alchemy.com/v2/YOUR_ALCHEMY_API_KEY
```
**QuickNode**:
```bash
ETHEREUM_MAINNET_RPC=https://your-endpoint.quiknode.pro/YOUR_API_KEY
```
**Public RPC** (not recommended for production):
```bash
ETHEREUM_MAINNET_RPC=https://eth.llamarpc.com
```
---
## 🚀 Recommended Action
**Easiest**: Disable "Private Key Only" in Infura dashboard settings.
This will allow the current RPC URL (line 18) to work without changes.
---
## ✅ After Fix
Once RPC is working, deployment will proceed automatically:
```bash
# Deploy MainnetTether
forge script script/DeployMainnetTether.s.sol \
--rpc-url "$ETHEREUM_MAINNET_RPC" \
--private-key $PRIVATE_KEY \
--broadcast \
--verify \
-vvvv
# Deploy TransactionMirror
forge script script/DeployTransactionMirror.s.sol \
--rpc-url "$ETHEREUM_MAINNET_RPC" \
--private-key $PRIVATE_KEY \

# Kaleido Tether and Mirror Pattern Implementation
**Date**: 2025-12-11
**Reference**: Kaleido's cross-chain architecture patterns
---
## 📚 Understanding Kaleido's Patterns
### **Tether Contract** (State Anchoring)
In Kaleido's architecture, a **Tether** contract is deployed on a public Ethereum network (e.g., Mainnet) that:
- Stores signed state proofs from a private blockchain network
- Creates an immutable, verifiable record of the private chain's state
- Anchors the private chain's state to the public network at specific intervals
- Provides security and transparency by making state proofs publicly verifiable
- Prevents collusion by requiring collective signatures from all nodes
**Purpose**: State anchoring and integrity verification across chains
---
### **Mirror Contract** (Address Registry)
In Kaleido's architecture, a **Mirror** contract:
- Maintains a registry of mirrored token/contract addresses across chains
- Maps source chain addresses to destination chain addresses
- Provides replay protection for cross-chain operations
- Enables address resolution for cross-chain interactions
**Purpose**: Address mapping and cross-chain contract resolution
---
## 🔍 Implementation in This Codebase
### 1. MirrorManager Contract ✅
**File**: `contracts/mirror/MirrorManager.sol`
**Status**: ✅ Available, ❌ Not deployed to Mainnet
**Functionality**:
- Registry of mirrored token/contract addresses across chains
- Mapping: `(sourceChain, sourceAddress) => (destChain => destAddress)`
- Replay protection via `processed` mapping
- Pausability for emergency stops
- Admin-controlled configuration
**Kaleido Pattern**: ✅ **Implements Mirror pattern**
**Deployment**:
```bash
forge script script/DeployMirrorManager.s.sol \
--rpc-url $ETH_MAINNET_RPC_URL \
--private-key $PRIVATE_KEY \
--broadcast \
--verify
```
**Required Environment Variables**:
- `MIRROR_ADMIN` - Admin address (multisig recommended)
---
### 2. TwoWayTokenBridge (Tether-like Pattern) ✅
**Files**:
- `contracts/bridge/TwoWayTokenBridgeL1.sol` (Mainnet/L1 side)
- `contracts/bridge/TwoWayTokenBridgeL2.sol` (Chain-138/L2 side)
**Status**: ✅ Available, ❌ Not deployed to Mainnet
**Functionality**:
- **L1 Side**: Locks canonical tokens and sends CCIP messages to mint on L2
- **L2 Side**: Mints mirrored tokens on inbound, burns on outbound
- State synchronization via CCIP messages
- Replay protection
- Destination chain configuration
**Kaleido Pattern**: ✅ **Implements Tether-like pattern** (state synchronization)
**Deployment**:
```bash
forge script script/DeployTwoWayBridge.s.sol \
--rpc-url $ETH_MAINNET_RPC_URL \
--private-key $PRIVATE_KEY \
--broadcast \
--verify
```
**Required Environment Variables**:
- `CCIP_ROUTER` - CCIP router address (set)
- `CCIP_FEE_TOKEN` - LINK token address (set)
- `BRIDGE_L1_TOKEN` - Canonical token on Mainnet (NOT SET)
- `BRIDGE_L2_TOKEN` - Mintable token on Chain-138 (NOT SET)
---
## 🔄 Relationship Between Contracts
### MirrorManager + TwoWayTokenBridge
1. **MirrorManager** maintains the address registry:
- Maps Mainnet token addresses to Chain-138 addresses
- Used by other contracts to resolve cross-chain addresses
2. **TwoWayTokenBridge** handles token transfers:
- Uses MirrorManager to resolve destination addresses
- Locks tokens on L1, mints on L2 (or vice versa)
- Maintains state synchronization via CCIP
### Typical Flow:
```
User on Mainnet
TwoWayTokenBridgeL1.lockAndSend()
CCIP Message → Chain-138
TwoWayTokenBridgeL2.ccipReceive()
MirrorManager.getMirror() → Resolve address
Mint mirrored tokens on Chain-138
```

# Set admin address (multisig recommended)
export MIRROR_ADMIN=0x...
# Deploy
forge script script/DeployMirrorManager.s.sol \
--rpc-url $ETH_MAINNET_RPC_URL \
--private-key $PRIVATE_KEY \
--broadcast \
--verify
# Update .env
echo "MIRRORMANAGER_MAINNET=<deployed_address>" >> .env
```
### Step 2: Deploy TwoWayTokenBridge
```bash
# Set token addresses
export BRIDGE_L1_TOKEN=0x... # Canonical token on Mainnet
export BRIDGE_L2_TOKEN=0x... # Mintable token on Chain-138
# Deploy (deploys both L1 and L2)
forge script script/DeployTwoWayBridge.s.sol \
--rpc-url $ETH_MAINNET_RPC_URL \
--private-key $PRIVATE_KEY \
--broadcast \
--verify
# Update .env
echo "TWOWAY_BRIDGE_L1_MAINNET=<l1_address>" >> .env
echo "TWOWAY_BRIDGE_L2_CHAIN138=<l2_address>" >> .env
```
### Step 3: Configure MirrorManager
```bash
# Register bridge addresses in MirrorManager
cast send $MIRRORMANAGER_MAINNET \
"setMirror(uint64,address,uint64,address)" \
1 \ # Mainnet chain selector
$TWOWAY_BRIDGE_L1_MAINNET \
138 \ # Chain-138 selector
$TWOWAY_BRIDGE_L2_CHAIN138 \
--rpc-url $ETH_MAINNET_RPC_URL \
--private-key $PRIVATE_KEY
```
### Step 4: Configure TwoWayTokenBridge
```bash
# Configure L1 bridge to point to L2
cast send $TWOWAY_BRIDGE_L1_MAINNET \
"addDestination(uint64,address)" \
138 \ # Chain-138 selector
$TWOWAY_BRIDGE_L2_CHAIN138 \
--rpc-url $ETH_MAINNET_RPC_URL \
--private-key $PRIVATE_KEY
# Configure L2 bridge to point to L1
cast send $TWOWAY_BRIDGE_L2_CHAIN138 \
"addDestination(uint64,address)" \
1 \ # Mainnet selector
$TWOWAY_BRIDGE_L1_MAINNET \
--rpc-url $RPC_URL_138 \
--private-key $PRIVATE_KEY
```

## 🔗 Integration with Existing Contracts
### CCIPWETH9Bridge / CCIPWETH10Bridge
The existing CCIP bridges can use MirrorManager to:
- Resolve destination addresses for cross-chain transfers
- Verify address mappings before processing transfers
- Maintain consistency across chains
### Example Integration:
```solidity
// In CCIPWETH9Bridge
MirrorManager mirror = MirrorManager(mirrorManagerAddress);
address destBridge = mirror.getMirror(
block.chainid,
address(this),
destChainSelector
);
```

## 📊 Comparison with Kaleido
| Feature | Kaleido Pattern | This Implementation |
|---------|----------------|---------------------|
| **State Anchoring** | Tether Contract | TwoWayTokenBridge |
| **Address Registry** | Mirror Contract | MirrorManager |
| **Cross-Chain Messaging** | Custom | CCIP (Chainlink) |
| **Replay Protection** | ✅ | ✅ |
| **Pausability** | ✅ | ✅ |
| **Admin Control** | ✅ | ✅ |
---
## ⚠️ Important Notes
1. **MirrorManager** should be deployed before TwoWayTokenBridge for proper address resolution
2. **TwoWayTokenBridge** requires mintable tokens on L2 (Chain-138)
3. Both contracts should use multisig for admin addresses
4. Configure MirrorManager mappings after deployment
5. Test with small amounts before production use

# Mainnet Tether and Transaction Mirror Implementation
**Date**: 2025-12-11
**Status**: Ready for Deployment
---
## 📋 Overview
This document describes the implementation of:
1. **MainnetTether** - Anchors Chain-138 state proofs to Ethereum Mainnet (Kaleido-style)
2. **TransactionMirror** - Mirrors Chain-138 transactions to Mainnet for Etherscan visibility
---
## 🔗 MainnetTether Contract
### Purpose
Following Kaleido's pattern, the MainnetTether contract:
- Stores signed state proofs from Chain-138 validators
- Creates immutable, verifiable records of Chain-138 state on Mainnet
- Anchors Chain-138 state at regular intervals
- Provides security and transparency through public verification
- Prevents collusion by requiring collective validator signatures
### Contract Details
**File**: `contracts/tether/MainnetTether.sol`
**Deployment Script**: `script/DeployMainnetTether.s.sol`
**Status**: ✅ Ready for deployment
### Key Features
- **State Proof Storage**: Stores block number, hash, state root, and validator signatures
- **Replay Protection**: Prevents duplicate state proofs
- **Block Anchoring**: Tracks all anchored blocks
- **Admin Control**: Pausable with admin-only functions
- **Query Functions**: Easy lookup of anchored state proofs
### Deployment
```bash
# Set admin address (multisig recommended)
export TETHER_ADMIN=0x...
# Deploy to Mainnet
forge script script/DeployMainnetTether.s.sol \
--rpc-url $ETH_MAINNET_RPC_URL \
--private-key $PRIVATE_KEY \
--broadcast \
--verify
# Update .env
echo "MAINNET_TETHER_ADDRESS=<deployed_address>" >> .env
```
### Usage
#### Anchor State Proof
```solidity
// Called by off-chain service that collects validator signatures
tether.anchorStateProof(
blockNumber, // Chain-138 block number
blockHash, // Chain-138 block hash
stateRoot, // Chain-138 state root
previousBlockHash, // Previous block hash
timestamp, // Block timestamp
signatures, // Collective validator signatures
validatorCount // Number of validators
);
```
#### Query State Proof
```solidity
// Check if block is anchored
bool anchored = tether.isAnchored(blockNumber);
// Get state proof details
StateProof memory proof = tether.getStateProof(blockNumber);
```
---
## 🔍 TransactionMirror Contract
### Purpose
The TransactionMirror contract:
- Logs all Chain-138 transactions as events on Mainnet
- Makes Chain-138 transactions searchable on Etherscan
- Provides transparency and auditability
- Enables cross-chain transaction visibility
### Contract Details
**File**: `contracts/mirror/TransactionMirror.sol`
**Deployment Script**: `script/DeployTransactionMirror.s.sol`
**Status**: ✅ Ready for deployment
### Key Features
- **Transaction Logging**: Stores transaction details (hash, from, to, value, etc.)
- **Event Emission**: Emits indexed events for Etherscan searchability
- **Batch Support**: Can mirror multiple transactions in one call
- **Replay Protection**: Prevents duplicate transaction mirroring
- **Query Functions**: Easy lookup of mirrored transactions
### Deployment
```bash
# Set admin address (multisig recommended)
export MIRROR_ADMIN=0x...
# Deploy to Mainnet
forge script script/DeployTransactionMirror.s.sol \
--rpc-url $ETH_MAINNET_RPC_URL \
--private-key $PRIVATE_KEY \
--broadcast \
--verify
# Update .env
echo "TRANSACTION_MIRROR_ADDRESS=<deployed_address>" >> .env
```
### Usage
#### Mirror Single Transaction
```solidity
// Called by off-chain service that monitors Chain-138
mirror.mirrorTransaction(
txHash, // Chain-138 transaction hash
from, // Sender address
to, // Recipient address
value, // Value transferred
blockNumber, // Chain-138 block number
blockTimestamp, // Block timestamp
gasUsed, // Gas used
success, // Transaction success status
data // Transaction data (optional)
);
```
#### Mirror Batch Transactions
```solidity
// Mirror multiple transactions at once (more gas efficient)
mirror.mirrorBatchTransactions(
txHashes, // Array of transaction hashes
froms, // Array of sender addresses
tos, // Array of recipient addresses
values, // Array of values
blockNumbers, // Array of block numbers
blockTimestamps, // Array of timestamps
gasUseds, // Array of gas used
successes, // Array of success statuses
datas // Array of transaction data
);
```
#### Query Mirrored Transaction
```solidity
// Check if transaction is mirrored
bool mirrored = mirror.isMirrored(txHash);
// Get transaction details
MirroredTransaction memory tx = mirror.getTransaction(txHash);
```
---
## 🔄 Integration with Off-Chain Services
### State Proof Anchoring Service
An off-chain service should:
1. Monitor Chain-138 blocks
2. Collect validator signatures for each block
3. Call `anchorStateProof()` on MainnetTether at regular intervals (e.g., every 6 hours)
4. Handle retries and error cases
### Transaction Mirroring Service
An off-chain service should:
1. Monitor Chain-138 for new transactions
2. Extract transaction details
3. Call `mirrorTransaction()` or `mirrorBatchTransactions()` on TransactionMirror
4. Batch transactions for gas efficiency
5. Handle retries and error cases
### Example Service Architecture
```
Chain-138 Network
Off-Chain Monitor Service
├─→ State Proof Collector → MainnetTether.anchorStateProof()
└─→ Transaction Monitor → TransactionMirror.mirrorTransaction()
Ethereum Mainnet
├─→ MainnetTether (state proofs)
└─→ TransactionMirror (transaction logs)
Etherscan (public visibility)
```

# Multichain Deployment Runbook
**Last Updated**: 2025-01-27
**Purpose**: Comprehensive guide for deploying smart contracts to multiple chains using Foundry
## Overview
This runbook covers deployment of the complete contract suite to:
- **Ethereum Mainnet** (chainId 1): Only CCIPLogger (other contracts already deployed)
- **Cronos** (chainId 25): All contracts
- **BSC** (chainId 56): All contracts
- **Polygon PoS** (chainId 137): All contracts
- **Gnosis Chain** (chainId 100): All contracts
## Prerequisites
### 1. Environment Setup
1. **Copy environment template**:
```bash
cp .env.example .env
```
2. **Fill in all required variables** in `.env`:
- `PRIVATE_KEY`: Your deployer private key
- RPC URLs for all chains
- Explorer API keys for verification
- CCIP router addresses per chain
- LINK token addresses per chain
3. **Verify Foundry installation**:
```bash
forge --version
# Should be >= 0.2.0
```
4. **Install dependencies** (if using Hardhat for CCIPLogger):
```bash
npm install
npm install @openzeppelin/contracts@5.0.2
npm install @chainlink/contracts-ccip
```
### 2. Verify Configuration
Check that all environment variables are set:
```bash
# Check mainnet config
echo $ETH_MAINNET_RPC_URL
echo $CCIP_ETH_ROUTER
echo $CCIP_ETH_LINK_TOKEN
# Check other chains
echo $CRONOS_RPC_URL
echo $BSC_RPC_URL
echo $POLYGON_RPC_URL
echo $GNOSIS_RPC_URL
```
### 3. Get Real-Time Gas Prices
Before checking balances, fetch real-time gas prices:
```bash
# Fetch real-time gas prices for all chains
./scripts/deployment/get-multichain-gas-prices.sh
# Update documentation with real-time prices
./scripts/deployment/update-gas-estimates.sh
```
This will:
- Fetch current gas prices from configured APIs
- Calculate deployment costs for all chains
- Update documentation with real-time estimates
- Show you exactly how much you need
### 4. Verify Wallet Balance
Ensure your deployer wallet has sufficient native tokens for gas:
```bash
# Check balances (adjust RPC URLs as needed)
cast balance $DEPLOYER_ADDRESS --rpc-url $ETH_MAINNET_RPC_URL
cast balance $DEPLOYER_ADDRESS --rpc-url $CRONOS_RPC_URL
cast balance $DEPLOYER_ADDRESS --rpc-url $BSC_RPC_URL
cast balance $DEPLOYER_ADDRESS --rpc-url $POLYGON_RPC_URL
cast balance $DEPLOYER_ADDRESS --rpc-url $GNOSIS_RPC_URL
```
**Recommended minimum balances** (see [Gas and Token Requirements](./GAS_AND_TOKEN_REQUIREMENTS.md) for details):
- Ethereum Mainnet: **0.20 ETH** (for CCIPLogger deployment)
- Cronos: **15 CRO** (for all 5 contracts)
- BSC: **0.06 BNB** (for all 5 contracts)
- Polygon: **1.0 MATIC** (for all 5 contracts)
- Gnosis: **0.05 xDAI** (for all 5 contracts)
**Total Estimated Cost**: ~$520 USD (with buffers)

## Post-Deployment Steps
### 1. Save Deployment Addresses
After each deployment, save the addresses to your `.env` file:
```bash
# Example for Cronos
echo "WETH9_CRONOS=<deployed_address>" >> .env
echo "WETH10_CRONOS=<deployed_address>" >> .env
echo "CCIPWETH9BRIDGE_CRONOS=<deployed_address>" >> .env
echo "CCIPWETH10BRIDGE_CRONOS=<deployed_address>" >> .env
echo "CCIPLOGGER_CRONOS=<deployed_address>" >> .env
```
### 2. Verify All Contracts
Verify all contracts on their respective explorers:
- [Etherscan](https://etherscan.io) (Mainnet)
- [Cronoscan](https://cronoscan.com) (Cronos)
- [BscScan](https://bscscan.com) (BSC)
- [Polygonscan](https://polygonscan.com) (Polygon)
- [Gnosisscan](https://gnosisscan.io) (Gnosis)
### 3. Configure Bridge Destinations
For each bridge contract, configure destination chains:
```bash
# Example: Configure WETH9 Bridge on Cronos to send to Mainnet
cast send <CCIPWETH9BRIDGE_CRONOS> \
"addDestination(uint64,address)" \
$ETH_MAINNET_SELECTOR \
$CCIPWETH9BRIDGE_MAINNET \
--rpc-url cronos \
--private-key $PRIVATE_KEY
```
### 4. Test Cross-Chain Transfers
Test a small cross-chain transfer to verify everything works:
```bash
# Example: Send WETH9 from Cronos to Mainnet
cast send <WETH9_CRONOS> \
"approve(address,uint256)" \
<CCIPWETH9BRIDGE_CRONOS> \
1000000000000000000 \
--rpc-url cronos \
--private-key $PRIVATE_KEY
cast send <CCIPWETH9BRIDGE_CRONOS> \
"sendCrossChain(uint64,address,uint256)" \
$ETH_MAINNET_SELECTOR \
<RECIPIENT_ADDRESS> \
1000000000000000000 \
--rpc-url cronos \
--private-key $PRIVATE_KEY
```

## Gas and Token Requirements
**📊 For detailed gas cost breakdowns and token requirements, see**: [Gas and Token Requirements](./GAS_AND_TOKEN_REQUIREMENTS.md)
### Quick Reference: Minimum Balances
| Chain | Token | Minimum | Recommended |
|-------|-------|---------|-------------|
| **Mainnet** | ETH | 0.15 ETH | **0.20 ETH** |
| **Cronos** | CRO | 8.76 CRO | **15 CRO** |
| **BSC** | BNB | 0.044 BNB | **0.06 BNB** |
| **Polygon** | MATIC | 0.44 MATIC | **1.0 MATIC** |
| **Gnosis** | xDAI | 0.0175 xDAI | **0.05 xDAI** |
### Total Gas Requirements
- **Ethereum Mainnet**: 3,000,000 gas (CCIPLogger only)
- **Other Chains**: 8,760,000 gas (all 5 contracts: WETH9, WETH10, 2 Bridges, CCIPLogger)
---
## Gas Price Strategies
### Ethereum Mainnet
- **Strategy**: Use EIP-1559 (automatic)
- **Max Fee**: Check current gas prices
- **Priority Fee**: 2-5 gwei
### Cronos
- **Strategy**: Fixed gas price
- **Gas Price**: ~500 gwei (very low)
- **Note**: Cronos uses CRO for gas
### BSC
- **Strategy**: Fixed gas price
- **Gas Price**: ~3-5 gwei
- **Note**: BSC uses BNB for gas
### Polygon
- **Strategy**: Fixed gas price
- **Gas Price**: ~30-100 gwei
- **Note**: Polygon uses MATIC for gas
### Gnosis
- **Strategy**: Fixed gas price
- **Gas Price**: ~1 gwei
- **Note**: Gnosis uses xDAI for gas
---
## Network-Specific Caveats
### Cronos
- **Finality**: ~6 seconds
- **CCIP Support**: Verify CCIP router availability
- **RPC**: May have rate limits
### BSC
- **Finality**: ~3 seconds
- **CCIP Support**: Verify CCIP router availability
- **Gas**: Very cheap, but watch for congestion
### Polygon
- **Finality**: ~2 seconds
- **CCIP Support**: ✅ Available
- **Router**: `0x3C3D92629A02a8D95D5CB9650fe49C3544f69B43`
- **LINK Token**: `0x53E0bca35eC356BD5ddDFebbD1Fc0fD03FaBad39`
### Gnosis
- **Finality**: ~5 seconds
- **CCIP Support**: Verify CCIP router availability
- **Gas**: Very cheap
---
## Troubleshooting
### RPC Connection Issues
```bash
# Test RPC connectivity
cast block-number --rpc-url $ETH_MAINNET_RPC_URL
cast block-number --rpc-url $CRONOS_RPC_URL
cast block-number --rpc-url $BSC_RPC_URL
cast block-number --rpc-url $POLYGON_RPC_URL
cast block-number --rpc-url $GNOSIS_RPC_URL
```
### Contract Verification Fails
1. **Check compiler settings match**:
```bash
# Verify optimizer settings
grep optimizer foundry.toml
grep optimizer_runs foundry.toml
```
2. **Verify constructor arguments**:
```bash
# Encode constructor args manually
cast abi-encode "constructor(address,address,address)" \
$ROUTER $WETH $LINK
```
3. **Use explicit verification**:
```bash
forge verify-contract \
--chain-id <CHAIN_ID> \
--num-of-optimizations 200 \
--watch \
<ADDRESS> \
<CONTRACT_PATH>:<CONTRACT_NAME> \
<API_KEY> \
--constructor-args <ENCODED_ARGS>
```
### CCIPLogger Deployment Issues
If CCIPLogger fails to deploy via Foundry:
1. Use Hardhat script instead: `npm run deploy:logger:mainnet`
2. Ensure OpenZeppelin v5.0.2+ is installed
3. Check that CCIP contracts are available

Before starting, ensure you have:
- [x] ✅ Azure CLI installed and authenticated
- [x]`.env` file configured with Azure and Cloudflare credentials
- [x] ✅ Validator and oracle keys generated
- [x] ✅ Genesis file created
- [x] ✅ Resource providers registered
- [ ] ⚠️ Terraform installed (run: `./scripts/setup/install-terraform.sh`)
- [ ] ⚠️ kubectl installed
- [ ] ⚠️ Helm 3.x installed
## Quick Deployment Steps
### Step 1: Install Missing Tools
```bash
# Install Terraform (if not installed)
./scripts/setup/install-terraform.sh
# Verify all tools
./scripts/deployment/prepare-all-phases.sh
```
### Step 2: Initialize Terraform
```bash
cd terraform
terraform init
```
### Step 3: Review Configuration
```bash
# Review terraform.tfvars
cat terraform.tfvars
# Verify naming convention
grep -E "az-p-we" terraform/locals.tf
```
### Step 4: Plan Deployment
```bash
terraform plan -out=tfplan
```
**Review the plan carefully:**
- Check resource names follow convention: `az-p-we-{resource}-{instance}`
- Verify region is `westeurope`
- Review estimated costs
- Check resource counts and sizes
### Step 5: Apply Infrastructure
```bash
terraform apply tfplan
```
**This will create:**
- Resource groups
- Virtual network and subnets
- Network security groups
- Key Vault
- Log Analytics workspace
- AKS cluster and node pools
- Application Gateway
- Storage accounts
**⏱️ Estimated time: 20-30 minutes**
### Step 6: Configure kubectl
```bash
# Get AKS credentials
az aks get-credentials \
--resource-group az-p-we-rg-comp-001 \
--name az-p-we-aks-main
# Verify connection
kubectl get nodes
```
### Step 7: Deploy Kubernetes Resources
```bash
# Create namespaces
kubectl apply -f k8s/base/namespace.yaml
# Deploy validators
helm install besu-validators ./helm/besu-network \
-f helm/besu-network/values-validators.yaml \
-n besu-network
# Deploy sentries
helm install besu-sentries ./helm/besu-network \
-f helm/besu-network/values-sentries.yaml \
-n besu-network
# Deploy RPC nodes
helm install besu-rpc ./helm/besu-network \
-f helm/besu-network/values-rpc.yaml \
-n besu-network
```
### Step 8: Configure DNS
```bash
# Get Application Gateway IP
AGW_IP=$(./scripts/deployment/get-app-gateway-ip.sh)
# Configure Cloudflare DNS
./scripts/deployment/cloudflare-dns.sh \
--zone-id $CLOUDFLARE_ZONE_ID \
--api-token $CLOUDFLARE_API_TOKEN \
--ip $AGW_IP
```
### Step 9: Deploy Contracts
```bash
# Set RPC URL (after DNS propagates)
export RPC_URL="https://rpc.d-bis.org"
export PRIVATE_KEY="<your-deployment-key>"
# Deploy contracts
./scripts/deployment/deploy-weth.sh
./scripts/deployment/deploy-multicall.sh
```
### Step 10: Verify Deployment
```bash
./scripts/deployment/verify-deployment.sh
```
## Automated Deployment
For a fully automated deployment (after prerequisites):
```bash
# Phase 1: Prerequisites (already done)
./scripts/deployment/deploy-phase1.sh
# Phase 2: Terraform setup
./scripts/deployment/deploy-phase2.sh
# Then manually:
cd terraform
terraform init
terraform plan
terraform apply # Requires confirmation
```
## Troubleshooting
### Terraform Not Found
```bash
./scripts/setup/install-terraform.sh
```
### Azure Authentication Issues
```bash
az login
az account show
```
### Resource Provider Not Registered
```bash
./scripts/azure/check-azure-prerequisites.sh
```
### Quota Issues
```bash
./scripts/azure/check-quotas.sh westeurope
```
## Resource Naming
All resources follow: `az-p-we-{resource}-{instance}`
Examples:
- AKS: `az-p-we-aks-main`

# Quick Start: Real-Time Gas Price Updates
**Last Updated**: 2025-01-27
## 🚀 One-Command Update
Update all gas estimates with real-time prices:
```bash
./scripts/deployment/get-multichain-gas-prices.sh && ./scripts/deployment/update-gas-estimates.sh
```
## What This Does
1. **Fetches Real-Time Gas Prices** from:
- Etherscan API (Ethereum Mainnet)
- RPC endpoints (all other chains)
2. **Calculates Costs**:
- In native tokens (ETH, CRO, BNB, MATIC, xDAI)
- In USD (using approximate exchange rates)
3. **Updates Documentation**:
- `GAS_AND_TOKEN_REQUIREMENTS.md`
- `TOKENS_AND_CHAINS_SUMMARY.md`
- `DEPLOYMENT_QUICK_REFERENCE.md`
## Prerequisites
Ensure `.env` has:
```bash
ETHERSCAN_API_KEY=your_key_here
ETH_MAINNET_RPC_URL=https://...
CRONOS_RPC_URL=https://...
BSC_RPC_URL=https://...
POLYGON_RPC_URL=https://...
GNOSIS_RPC_URL=https://...
```
## Output
After running, you'll see:
- Current gas prices for all chains
- Deployment cost estimates
- Total estimated cost in USD
- Confirmation of documentation updates
## Example Output
```
========================================
Multichain Gas Price Fetcher
========================================
Current Gas Prices:
Ethereum Mainnet: 0.14 gwei
Cronos: 378.75 gwei
BSC: 0.05 gwei
Polygon: 34.61 gwei

# Real-Time Gas Price System
**Last Updated**: 2025-01-27
## Overview
The multichain deployment system now includes **real-time gas price fetching** using APIs configured in your `.env` file. This ensures all cost estimates are based on current market conditions, not outdated static values.
## Quick Start
```bash
# 1. Ensure .env is configured with API keys and RPC URLs
# 2. Fetch real-time gas prices
./scripts/deployment/get-multichain-gas-prices.sh
# 3. Update all documentation
./scripts/deployment/update-gas-estimates.sh
```
## What Gets Updated
The system updates the following documentation files with real-time gas prices:
1. **`GAS_AND_TOKEN_REQUIREMENTS.md`**
- Gas price tables for all chains
- Cost estimates in native tokens
- USD cost estimates
- Recommended balances
2. **`TOKENS_AND_CHAINS_SUMMARY.md`**
- Recommended token balances
- Cost estimates per chain
- Total deployment costs
3. **`DEPLOYMENT_QUICK_REFERENCE.md`**
- Quick reference tables
- Minimum balances
- Cost estimates
## How It Works
### 1. Gas Price Fetching
The `get-multichain-gas-prices.sh` script:
- **Ethereum Mainnet**: Uses Etherscan Gas API v2 (via `ETHERSCAN_API_KEY`)
- **Other Chains**: Uses RPC `eth_gasPrice` calls (via `*_RPC_URL` variables)
- **Fallbacks**: Uses sensible defaults if APIs are unavailable
### 2. Cost Calculation
For each chain:
```
Cost (Native Token) = (Gas Units × Gas Price in Wei) / 10^18
Cost (USD) = Cost (Native Token) × Token Price (USD)
```
### 3. Documentation Updates
The `update-gas-estimates.sh` script:
- Reads gas price data from the fetcher
- Updates all markdown files with current values
- Updates timestamps
- Maintains formatting and structure
## Configuration
### Required in `.env`
```bash
# Ethereum Mainnet (for Etherscan API)
ETHERSCAN_API_KEY=your_api_key_here
ETH_MAINNET_RPC_URL=https://eth-mainnet.g.alchemy.com/v2/YOUR_KEY
# Other Chains (RPC endpoints)
CRONOS_RPC_URL=https://evm.cronos.org
BSC_RPC_URL=https://bsc-dataseed1.binance.org
POLYGON_RPC_URL=https://polygon-rpc.com
GNOSIS_RPC_URL=https://rpc.gnosischain.com
```
### Optional
```bash
# Infura Gas API (alternative to Etherscan)
INFURA_GAS_API=your_infura_api_key_here
```
## Example Output
```

```bash
INFURA_GAS_API=your_infura_api_key_here
# Or full URL:
INFURA_GAS_API=https://gas.api.infura.io/networks/1/suggestedGasFees
```
## Gas Price Sources
### Ethereum Mainnet
1. **Etherscan Gas API v2** (Primary)
- Endpoint: `https://api.etherscan.io/v2/api?chainid=1&module=gastracker&action=gasoracle&apikey={API_KEY}`
- Returns: SafeGasPrice, ProposeGasPrice, FastGasPrice
- Uses: FastGasPrice for estimates
2. **RPC Endpoint** (Fallback)
- Uses `eth_gasPrice` RPC call
- Via `ETH_MAINNET_RPC_URL`
3. **Default** (Final Fallback)
- 20 gwei if all APIs fail
### Other Chains
1. **RPC Endpoint** (Primary)
- Uses `eth_gasPrice` RPC call
- Via `*_RPC_URL` environment variables
2. **Default** (Fallback)
- Chain-specific defaults:
- Cronos: 1,000 gwei (1 gwei in ETH terms)
- BSC: 5 gwei
- Polygon: 50 gwei
- Gnosis: 2 gwei
## Cost Calculation
### Formula
```
Cost (Native Token) = (Gas Units × Gas Price in Wei) / 10^18
Cost (USD) = Cost (Native Token) × Token Price (USD)
```
### Gas Units
- **Ethereum Mainnet**: 3,000,000 gas (CCIPLogger only)
- **Other Chains**: 8,760,000 gas (all 5 contracts with 20% buffer)
### Exchange Rates
Current approximate rates (update as needed):
- ETH: $2,500
- CRO: $0.08
- BNB: $300
- MATIC: $0.80
- xDAI: $1.00
## JSON Output Format
The script saves data to `/tmp/multichain_gas_prices.json`:
```json
{
"timestamp": "2025-01-27 12:00:00 UTC",
"gas_prices": {
"ethereum_mainnet": {
"gwei": "25.5",
"wei": "25500000000",
"gas_units": 3000000,
"cost_eth": "0.0765",
"cost_usd": "191.25"
},
"cronos": {
"gwei": "1.2",
"wei": "1200000000",
"gas_units": 8760000,
"cost_cro": "10.512",
"cost_usd": "0.84"
},
...
},
"total_usd": "520.05"
}
```
## Integration with CI/CD
You can integrate this into your deployment pipeline:
```bash
#!/bin/bash
# Pre-deployment gas check
# Fetch real-time prices
./scripts/deployment/get-multichain-gas-prices.sh
# Check if costs are acceptable
ETH_COST=$(jq -r '.gas_prices.ethereum_mainnet.cost_eth' /tmp/multichain_gas_prices.json)
ETH_THRESHOLD=0.20
if (( $(echo "$ETH_COST > $ETH_THRESHOLD" | bc -l) )); then
echo "⚠️ Gas costs are high ($ETH_COST ETH). Consider waiting."
exit 1
fi
# Proceed with deployment
echo "✓ Gas costs acceptable. Proceeding with deployment."
```
## Troubleshooting
### Script Fails to Fetch Gas Prices
1. **Check API Keys**:
```bash
echo $ETHERSCAN_API_KEY
echo $ETH_MAINNET_RPC_URL
```
2. **Test API Endpoints**:
```bash
# Test Etherscan API
curl -s "https://api.etherscan.io/v2/api?chainid=1&module=gastracker&action=gasoracle&apikey=${ETHERSCAN_API_KEY}"
# Test RPC endpoints
cast gas-price --rpc-url $ETH_MAINNET_RPC_URL
```
3. **Check Network Connectivity**:
```bash
ping -c 1 api.etherscan.io
```
### Documentation Not Updating
1. **Check File Permissions**:
```bash
ls -la docs/deployment/*.md
```
2. **Verify Script Execution**:
```bash
./scripts/deployment/get-multichain-gas-prices.sh
./scripts/deployment/update-gas-estimates.sh
```
3. **Check JSON File**:
```bash
cat /tmp/multichain_gas_prices.json
```
## Best Practices
1. **Update Before Deployment**: Always run the scripts before deploying
2. **Monitor Gas Prices**: Gas prices fluctuate - check regularly
3. **Use Buffers**: Recommended balances include 20-50% buffer
4. **Test on Testnets**: Verify everything works before mainnet
5. **Document Changes**: Note any manual adjustments to estimates

## 💡 Cost Optimization Tips
1. **Deploy During Low Gas**: Monitor gas prices and deploy during off-peak hours
2. **Batch Operations**: Deploy multiple contracts in sequence to save on transaction overhead
3. **Test on Testnets First**: Verify everything works before mainnet deployment
4. **Use Gas Trackers**: Check real-time gas prices before deploying
5. **Consider Layer 2**: Some chains have lower gas costs
---
## 🔍 Verification Commands
Check your balances before deployment:
```bash
# Ethereum Mainnet
cast balance $DEPLOYER_ADDRESS --rpc-url $ETH_MAINNET_RPC_URL
# Cronos
cast balance $DEPLOYER_ADDRESS --rpc-url $CRONOS_RPC_URL
# BSC
cast balance $DEPLOYER_ADDRESS --rpc-url $BSC_RPC_URL
# Polygon
cast balance $DEPLOYER_ADDRESS --rpc-url $POLYGON_RPC_URL
# Gnosis
cast balance $DEPLOYER_ADDRESS --rpc-url $GNOSIS_RPC_URL
```

- **Option 1**: Upgrade to Standard_B2s (2 vCPUs, 4GB RAM)
- **Option 2**: Upgrade to Standard_D2s_v3 (2 vCPUs, 8GB RAM)
- **Option 3**: Increase node count (need quota increase)
### Cost Comparison
- **Standard_B1ms**: ~$7.50/month (current)
- **Standard_B2s**: ~$15/month (2× cost, 2× vCPUs)
- **Standard_D2s_v3**: ~$70/month (9× cost, 2× vCPUs)

**Legend**: ✅ = Required, ⚪ = Optional (distributed)
## Per-Region Configuration
### Standard Configuration
```hcl
node_count = {
system = 1 # Required for AKS
validators = 1 # Required in ALL regions (SAME VM size)
sentries = 0 # Optional, distributed as needed
rpc = 1 # Required in ALL regions (core backbone)
}
vm_families = {
system = "Standard_D2_v2" # 2 vCPUs - Dv2 Family
validators = "Standard_D4_v2" # 4 vCPUs - Dv2 Family (SAME across ALL)
sentries = "Standard_D4_v2" # 4 vCPUs - Dv2 Family (distributed)
rpc = "Standard_D8s_v6" # 8 vCPUs - Dsv6 Family (SAME across ALL)
}
```
### Quota Requirements Per Region
- **Dv2 Family**: 6 vCPUs (system: 2, validators: 4, sentries: 0)
- **Dsv6 Family**: 8 vCPUs (RPC: 8)
- **Total**: 14 vCPUs per region (minimum)
With sentries:
- **Dv2 Family**: 10 vCPUs (system: 2, validators: 4, sentries: 4)
- **Dsv6 Family**: 8 vCPUs (RPC: 8)
- **Total**: 18 vCPUs per region (with sentries)
## Total Deployment Summary
### Global Resources
- **Total Regions**: 42 (all non-US Commercial Azure)
- **Total Validator Nodes**: 42 (1 per region, SAME VM size)
- **Total RPC Nodes**: 42 (1 per region, core backbone)
- **Total System Nodes**: 42 (1 per region, AKS)
- **Total Sentry Nodes**: 0-42 (distributed as needed)
- **Total Nodes**: 126-168 nodes
### Total vCPUs
**Minimum (without sentries)**:
- **Dv2 Family**: 252 vCPUs (6 per region × 42)
- **Dsv6 Family**: 336 vCPUs (8 per region × 42)
- **Total**: 588 vCPUs
**Maximum (with sentries)**:
- **Dv2 Family**: 420 vCPUs (10 per region × 42)
- **Dsv6 Family**: 336 vCPUs (8 per region × 42)
- **Total**: 756 vCPUs
## Key Design Principles
### 1. Validator Consistency
- **Same VM size** (`Standard_D4_v2`) across ALL 42 regions
- Ensures consistent performance and behavior
- Simplifies monitoring and management
- Critical for consensus reliability
### 2. RPC Backbone
- **RPC nodes in ALL 42 regions** for core backbone
- Internally networked for high availability
- Critical infrastructure component
- Same VM size (`Standard_D8s_v6`) across all regions
### 3. Flexible Distribution
- **System nodes**: Required in all regions (AKS)
- **Sentry nodes**: Distributed based on quotas and needs
- Allows optimization per region
## Deployment Configuration
The configuration is defined in `terraform/multi-region-global.tf`:
- Uses `local.standard_validator_vm_size = "Standard_D4_v2"` for all validators
- Uses `local.standard_rpc_vm_size = "Standard_D8s_v6"` for all RPC nodes
- Automatically generates configuration for all 42 regions
- Ensures consistency across all regions
## Monitoring
### Validator Monitoring
- Monitor all 42 validator nodes
- Ensure all use `Standard_D4_v2`
- Track consensus health across regions
- Alert on any validator VM size deviations
### RPC Backbone Monitoring
- Monitor all 42 RPC nodes
- Ensure all use `Standard_D8s_v6`
- Track internal networking health
- Monitor cross-region connectivity
## Benefits
1. **Consistent Validators**: Same VM size ensures uniform behavior
2. **Resilient Backbone**: RPC nodes in all regions for redundancy
3. **Global Coverage**: 42 regions provide worldwide presence
4. **Flexible Scaling**: System/sentry nodes can be adjusted per region
5. **High Availability**: Geographic redundancy across all regions

# VM Deployment Guide
## Overview
This guide describes how to deploy the Besu network on Azure Virtual Machines (VMs) or Virtual Machine Scale Sets (VMSS) with Docker Engine, as an alternative to AKS deployment.
## Architecture
### Deployment Options
1. **Individual VMs**: Separate VMs for each node (validators, sentries, RPC)
2. **VM Scale Sets**: Auto-scaling VM groups for each node type
3. **Multi-Region**: Deploy nodes across multiple Azure regions for high availability
### Node Types
- **Validators**: Private subnets, no public IPs, IBFT2 consensus
- **Sentries**: Public-facing P2P nodes, peer to validators and sentries
- **RPC Nodes**: Public HTTPS JSON-RPC, no P2P, read-only
## Prerequisites
- Azure CLI installed and configured
- Terraform >= 1.0
- SSH key pair for VM access
- Azure subscription with appropriate permissions
- Resource group created
## Quick Start
### 1. Generate SSH Key (if not exists)
```bash
ssh-keygen -t rsa -b 4096 -C "besu-vm-deployment"
```
### 2. Set Environment Variables
```bash
export SSH_PUBLIC_KEY=$(cat ~/.ssh/id_rsa.pub)
export AZURE_SUBSCRIPTION_ID="your-subscription-id"
export RESOURCE_GROUP_NAME="defi-oracle-mainnet-rg"
export CLUSTER_NAME="defi-oracle-aks"
```
### 3. Configure Terraform Variables
```bash
# Copy example variables file
cp terraform/terraform.tfvars.vm.example terraform/terraform.tfvars.vm
# Edit terraform.tfvars.vm with your values
# Set vm_deployment_enabled = true
# Set ssh_public_key = "$(cat ~/.ssh/id_rsa.pub)"
```
### 4. Deploy Infrastructure
```bash
# Initialize Terraform
cd terraform
terraform init
# Plan deployment (VM deployment)
terraform plan -var-file=terraform.tfvars.vm -var="vm_deployment_enabled=true"
# Apply deployment
terraform apply -var-file=terraform.tfvars.vm -var="vm_deployment_enabled=true"
```
### 5. Alternative: Use Deployment Script
```bash
# Use the deployment script
./scripts/vm-deployment/deploy-vm-network.sh
```
### 4. Setup VMs
After VMs are created, they will be automatically configured via cloud-init. To manually setup:
```bash
# SSH into VM
ssh besuadmin@<vm-public-ip>
# Run setup script
sudo /opt/besu/setup.sh
```
### 5. Verify Deployment
```bash
# Check VM status
az vm list --resource-group $RESOURCE_GROUP_NAME --show-details
# Check Besu container status
ssh besuadmin@<vm-ip> "docker ps"
# Check Besu logs
ssh besuadmin@<vm-ip> "docker logs besu-validator-0"
```
## Manual VM Setup
### 1. Create VM
```bash
# Create resource group
az group create --name $RESOURCE_GROUP_NAME --location eastus
# Create VM
az vm create \
--resource-group $RESOURCE_GROUP_NAME \
--name besu-validator-0 \
--image Ubuntu2204 \
--size Standard_D4s_v3 \
--admin-username besuadmin \
--ssh-key-values ~/.ssh/id_rsa.pub \
--vnet-name besu-vnet \
--subnet validators-subnet \
--nsg besu-validator-nsg
```
### 2. Setup VM
```bash
# Copy setup script to VM
scp scripts/vm-deployment/setup-vm.sh besuadmin@<vm-ip>:~
# SSH into VM
ssh besuadmin@<vm-ip>
# Run setup script
sudo bash setup-vm.sh validator 0
```
### 3. Configure Besu
```bash
# Copy configuration files
scp config/genesis.json besuadmin@<vm-ip>:~/genesis.json
scp config/validators/besu-config.toml besuadmin@<vm-ip>:~/besu-config.toml
# Copy validator keys
scp keys/validator-0/* besuadmin@<vm-ip>:~/keys/
```
### 4. Start Besu
```bash
# SSH into VM
ssh besuadmin@<vm-ip>
# Start Besu container
cd /opt/besu
docker compose up -d
# Check status
docker ps
docker logs besu-validator-0
```
## VM Scale Sets Deployment
### Deploy VM Scale Set
```bash
# Update terraform.tfvars.vm
use_vmss = true
# Apply Terraform
terraform apply -var-file=terraform.tfvars.vm
```
### Scale VM Scale Set
```bash
# Scale validators
az vmss scale \
--resource-group $RESOURCE_GROUP_NAME \
--name besu-validator-vmss \
--new-capacity 4
# Scale RPC nodes
az vmss scale \
--resource-group $RESOURCE_GROUP_NAME \
--name besu-rpc-vmss \
--new-capacity 5
```
## Multi-Region Deployment
### Deploy to Multiple Regions
```bash
# Update terraform.tfvars.vm
vm_regions = ["eastus", "westus", "westeurope", "southeastasia"]
# Apply Terraform
terraform apply -var-file=terraform.tfvars.vm
```
### Configure Cross-Region Peering
```bash
# Create VNet peering between regions
az network vnet peering create \
--resource-group $RESOURCE_GROUP_NAME \
--name eastus-to-westus \
--vnet-name besu-vnet-eastus \
--remote-vnet besu-vnet-westus \
--allow-vnet-access
```
## Monitoring
### View VM Metrics
```bash
# View VM metrics
az monitor metrics list \
--resource /subscriptions/$SUBSCRIPTION_ID/resourceGroups/$RESOURCE_GROUP_NAME/providers/Microsoft.Compute/virtualMachines/besu-validator-0 \
--metric "Percentage CPU" \
--start-time 2024-01-01T00:00:00Z
```
### View Besu Logs
```bash
# SSH into VM
ssh besuadmin@<vm-ip>
# View logs
docker logs -f besu-validator-0
# View logs from file
tail -f /opt/besu/logs/besu.log
```
### View Metrics
```bash
# Check metrics endpoint
curl http://<vm-ip>:9545/metrics
```
## Backup and Recovery
### Backup Chaindata
```bash
# SSH into VM
ssh besuadmin@<vm-ip>
# Stop Besu
docker compose down
# Backup data
tar -czf besu-data-backup-$(date +%Y%m%d).tar.gz /opt/besu/data
# Upload to Azure Storage
az storage blob upload \
--account-name $STORAGE_ACCOUNT_NAME \
--container-name backups \
--name besu-data-backup-$(date +%Y%m%d).tar.gz \
--file besu-data-backup-$(date +%Y%m%d).tar.gz
# Restart Besu
docker compose up -d
```
### Restore Chaindata
```bash
# Download backup
az storage blob download \
--account-name $STORAGE_ACCOUNT_NAME \
--container-name backups \
--name besu-data-backup-20240101.tar.gz \
--file besu-data-backup-20240101.tar.gz
# Stop Besu
docker compose down
# Restore data
tar -xzf besu-data-backup-20240101.tar.gz -C /
# Restart Besu
docker compose up -d
```
## Troubleshooting
### VM Not Accessible
```bash
# Check VM status
az vm show --resource-group $RESOURCE_GROUP_NAME --name besu-validator-0 --show-details
# Check NSG rules
az network nsg rule list --resource-group $RESOURCE_GROUP_NAME --nsg-name besu-validator-nsg
# Restart VM
az vm restart --resource-group $RESOURCE_GROUP_NAME --name besu-validator-0
```
### Besu Container Not Starting
```bash
# SSH into VM
ssh besuadmin@<vm-ip>
# Check container logs
docker logs besu-validator-0
# Check systemd service
systemctl status besu.service
# Check Docker
docker ps -a
systemctl status docker
```
### Network Issues
```bash
# Check network connectivity
ping <validator-ip>
# Check P2P port
telnet <sentry-ip> 30303
# Check RPC port
curl http://<rpc-ip>:8545
```
## Cost Optimization
### Use Spot VMs
```bash
# Create VM with spot pricing
az vm create \
--resource-group $RESOURCE_GROUP_NAME \
--name besu-validator-0 \
--priority Spot \
--max-price -1 \
--eviction-policy Deallocate
```
### Use Reserved Instances
```bash
# Purchase reserved instance
az vm reservation create \
--resource-group $RESOURCE_GROUP_NAME \
--reserved-resource-type VirtualMachines \
--billing-scope /subscriptions/$SUBSCRIPTION_ID \
--term P1Y \
--quantity 1 \
--sku Standard_D4s_v3
```
## Security
### Network Security
- Use Network Security Groups (NSGs) to restrict access
- Use private subnets for validators
- Use public IPs only for sentries and RPC nodes
- Implement firewall rules
### Key Management
- Use Azure Key Vault for validator keys
- Use Managed Identity for Key Vault access
- Rotate keys regularly
- Backup keys securely
### Access Control
- Use SSH keys instead of passwords
- Disable root login
- Use Azure AD for VM access
- Implement just-in-time access
## Comparison: AKS vs VM Deployment
### AKS Deployment
**Pros**:
- Kubernetes orchestration
- Auto-scaling
- Service discovery
- Rolling updates
- Resource management
**Cons**:
- More complex setup
- Higher cost (control plane)
- Requires Kubernetes expertise
### VM Deployment
**Pros**:
- Simpler setup
- Lower cost (no control plane)
- Full control over VMs
- Easy to understand
- Direct Docker access
**Cons**:
- Manual scaling
- Manual updates
- No service discovery
- More manual configuration
## Recommendations
1. **Use AKS for production**: Better orchestration and management
2. **Use VMs for development**: Simpler and cheaper
3. **Use VMSS for auto-scaling**: Better than individual VMs
4. **Multi-region deployment**: High availability and disaster recovery
5. **Use Managed Disks**: Better performance and reliability
