# Complete Next Steps Guide - Phase 2 & Smart Contract Deployment

## Overview

This guide provides comprehensive next steps for completing the DeFi Oracle Meta Mainnet (ChainID 138) deployment, including Phase 2 infrastructure deployment and all smart contract deployments.

**⚡ Full Parallel Mode**: All operations run in parallel where possible for maximum speed (~3-4x faster)

**🔧 .env Integration**: All configuration uses `.env` file - single source of truth, no duplication

---

## Quick Start (Full Parallel)

```bash
# 1. Ensure .env is configured
source .env

# 2. Deploy everything in parallel (fastest)
./scripts/deployment/deploy-phase2-and-contracts-parallel.sh

# Or step-by-step parallel:
./scripts/deployment/generate-phase2-tfvars.sh
cd terraform/phases/phase2 && terraform apply
./terraform/phases/phase2/scripts/start-services.sh all
source .env && ./scripts/deployment/deploy-contracts-parallel.sh
./scripts/deployment/verify-contracts-parallel.sh
```

**Estimated Time**: ~10-15 minutes (vs ~40 minutes sequential)

## Phase 2 Deployment Completion

### Prerequisites: Load .env Configuration

**Important**: All configuration is managed through `.env` file. Ensure you have a `.env` file in the project root with required variables:

```bash
# Load .env if not already loaded
cd /home/intlc/projects/smom-dbis-138
source .env  # or: set -a && source .env && set +a

# Required variables (add to .env if missing):
# ENVIRONMENT=prod
# VM_ADMIN_USERNAME=besuadmin
# SSH_PRIVATE_KEY_PATH=/path/to/ssh/private/key
```

### Step 1: Verify Phase 1 Completion

```bash
cd terraform/phases/phase1
terraform output phase1_us_regions
terraform output ssh_connection_strings
```

**Expected Output**: 5 regions (centralus, eastus, eastus2, westus, westus2) with VM information.

### Step 2: Generate Phase 2 Configuration (Automated)

**Use the helper script to generate `terraform.tfvars` from Phase 1 outputs and `.env`:**

```bash
# This script reads .env and Phase 1 outputs, generates terraform.tfvars automatically
./scripts/deployment/generate-phase2-tfvars.sh

# Review generated file
cat terraform/phases/phase2/terraform.tfvars
```

**Manual alternative** (if script fails):

Ensure your `.env` has these variables, then create `terraform/phases/phase2/terraform.tfvars` manually:

```hcl
environment = "${ENVIRONMENT:-prod}"
vm_admin_username = "${VM_ADMIN_USERNAME:-besuadmin}"
ssh_private_key_path = "${SSH_PRIVATE_KEY_PATH}"

# Phase 1 VM information - get from: terraform/phases/phase1/terraform output -json phase1_us_regions
phase1_vm_info = {
  # ... (paste output from Phase 1)
}
```

### Step 3: Deploy Phase 2 Docker Compose Files (Parallel)

**Terraform deploys to all 5 regions in parallel automatically:**

```bash
cd terraform/phases/phase2
terraform init
terraform plan
terraform apply

# All regions deploy concurrently - no sequential steps needed
```

### Step 4: Start Phase 2 Services (Full Parallel)

**All regions start simultaneously - script handles parallelization automatically:**

```bash
cd terraform/phases/phase2/scripts

# Start all regions in parallel (automatically parallelized)
./start-services.sh all

# Script automatically:
# - Starts all 5 regions simultaneously
# - Waits for all to complete
# - Reports success/failure for each region
# - Exits with error if any region fails
```

### Step 5: Verify Phase 2 Deployment (Full Parallel)

**All regions checked simultaneously with organized output:**

```bash
cd terraform/phases/phase2/scripts

# Check all regions in parallel (automatically parallelized)
./status.sh all

# Script automatically:
# - Checks all 5 regions simultaneously
# - Collects output from each region
# - Displays results in order
# - Cleans up temporary files
```

**Expected**: All docker-compose services running (Besu, FireFly, Cacti, Chainlink, databases, monitoring) across all 5 regions.

---

## Prerequisites for Contract Deployment

### 1. Environment Setup

**Ensure `.env` file exists in project root** (created/updated from Phase 2 setup):

```bash
# Load .env
cd /home/intlc/projects/smom-dbis-138
source .env

# Required variables in .env:
# RPC Configuration
RPC_URL=http://<besu-rpc-node>:8545
CHAIN_ID=138

# Deployer Configuration
PRIVATE_KEY=<your_deployer_private_key>
DEPLOYER_ADDRESS=<your_deployer_address>  # Optional: auto-calculated from PRIVATE_KEY

# CCIP Configuration (required for bridges)
CCIP_ROUTER=<ccip_router_address_or_leave_empty_to_deploy>
CCIP_FEE_TOKEN=<link_token_address_or_zero_address_for_native>  # Use 0x0000000000000000000000000000000000000000 for native

# Oracle Configuration
ORACLE_DESCRIPTION="ETH/USD Price Feed"
ORACLE_HEARTBEAT=60
ORACLE_DEVIATION_THRESHOLD=50

# Deployment Flags
DEPLOY_WETH9=true
DEPLOY_WETH10=true
DEPLOY_BRIDGES=true

# MultiSig Configuration (optional)
MULTISIG_OWNERS=<comma_separated_owner_addresses>  # e.g., "0x123...,0x456...,0x789..."
```

**All deployment scripts automatically load `.env`** - no need to manually export variables.

### 2. Fund Deployer Address

Ensure your deployer address has sufficient native tokens (ETH) for:
- Contract deployment gas costs
- CCIP fees (if using native token)
- Initial contract setup transactions

**Estimated Costs**: ~0.1-0.5 ETH for complete deployment

### 3. Verify RPC Connection

```bash
# Test RPC endpoint
curl -X POST $RPC_URL \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'
```

### 4. Compile Contracts

```bash
forge build
forge test  # Run tests before deployment
```

---

## Smart Contract Deployment Sequence

### Deployment Order (Critical - Must Follow This Sequence)

```
1. CCIP Router (if deploying custom)
2. LINK Token (if deploying, or use existing/zero address)
3. Multicall
4. CREATE2 Factory
5. WETH9
6. WETH10
7. CCIPWETH9Bridge
8. CCIPWETH10Bridge
9. Oracle Aggregator
10. Oracle Proxy
11. MultiSig (Governance)
12. CCIP Sender/Receiver (if needed)
```

### Method 1: Parallel Automated Deployment (Recommended)

**Use the parallel deployment script** (faster than sequential):

```bash
cd /home/intlc/projects/smom-dbis-138
source .env  # Ensure .env is loaded

# Parallel deployment (deploys independent contracts simultaneously)
./scripts/deployment/deploy-contracts-parallel.sh
```

This script:
- **Phase 1**: Deploys independent contracts in parallel (Multicall, WETH9, WETH10 simultaneously)
- **Phase 2**: Deploys CCIP Router (if needed)
- **Phase 3**: Deploys bridge contracts in parallel (CCIPWETH9Bridge, CCIPWETH10Bridge simultaneously)
- **Phase 4**: Deploys Oracle and MultiSig in parallel (independent contracts)
- Automatically updates `.env` with deployed addresses
- Handles dependencies between contracts
- Provides deployment summary

**Performance**: ~3-4x faster than sequential deployment (all independent operations run simultaneously).

### Method 1b: Sequential Automated Deployment (Alternative)

If you prefer sequential deployment or encounter parallel execution issues:

```bash
cd /home/intlc/projects/smom-dbis-138
source .env  # Ensure .env is loaded

# Sequential deployment (safer, slower)
./scripts/deployment/deploy-contracts-ordered.sh
```

This script:
- Deploys all contracts in correct order (one at a time)
- Automatically updates `.env` with deployed addresses
- Handles dependencies between contracts
- Provides deployment summary

### Method 2: Manual Step-by-Step Deployment

#### Step 1: Load Environment

```bash
cd /home/intlc/projects/smom-dbis-138
source .env  # Load all variables from .env
```

#### Step 2: Deploy Independent Contracts in Parallel

**Deploy Multicall, WETH9, and WETH10 simultaneously** (they have no dependencies):

```bash
# Parallel deployment of independent contracts
forge script script/DeployMulticall.s.sol:DeployMulticall \
  --rpc-url "$RPC_URL" \
  --broadcast \
  --private-key "$PRIVATE_KEY" \
  --verify &
MULTICALL_PID=$!

forge script script/DeployWETH.s.sol:DeployWETH \
  --rpc-url "$RPC_URL" \
  --broadcast \
  --private-key "$PRIVATE_KEY" \
  --verify &
WETH9_PID=$!

forge script script/DeployWETH10.s.sol:DeployWETH10 \
  --rpc-url "$RPC_URL" \
  --broadcast \
  --private-key "$PRIVATE_KEY" \
  --verify &
WETH10_PID=$!

# Wait for all to complete
wait $MULTICALL_PID
wait $WETH9_PID
wait $WETH10_PID

# Extract addresses and update .env (scripts handle this automatically)
source .env  # Reload to get new addresses
```

#### Step 3: Deploy CCIP Router (if needed)

```bash
# If deploying custom CCIP Router
if [ -z "$CCIP_ROUTER" ] || [ "$CCIP_ROUTER" = "0x0000000000000000000000000000000000000000" ]; then
    forge script script/DeployCCIPRouter.s.sol:DeployCCIPRouter \
      --sig "run(address,uint256,uint256)" \
      "${CCIP_FEE_TOKEN:-0x0000000000000000000000000000000000000000}" \
      "1000000000000000" \
      "1000000000" \
      --rpc-url "$RPC_URL" \
      --broadcast \
      --private-key "$PRIVATE_KEY" \
      --verify
    # Update .env with deployed address (use deploy script's auto-update feature)
fi

source .env  # Reload
```

**Note**: If using Chainlink's official CCIP Router, set `CCIP_ROUTER` in `.env` to the official address.

#### Step 4: Deploy CCIP Bridges in Parallel

**Deploy both bridges simultaneously** (they depend on CCIP_ROUTER and WETH addresses):

```bash
# Ensure dependencies are in .env
source .env

# Parallel bridge deployment
forge script script/DeployCCIPWETH9Bridge.s.sol:DeployCCIPWETH9Bridge \
  --rpc-url "$RPC_URL" \
  --broadcast \
  --private-key "$PRIVATE_KEY" \
  --verify &
BRIDGE9_PID=$!

forge script script/DeployCCIPWETH10Bridge.s.sol:DeployCCIPWETH10Bridge \
  --rpc-url "$RPC_URL" \
  --broadcast \
  --private-key "$PRIVATE_KEY" \
  --verify &
BRIDGE10_PID=$!

wait $BRIDGE9_PID
wait $BRIDGE10_PID

source .env  # Reload addresses
```

#### Step 5: Deploy Oracle and MultiSig in Parallel

**Deploy Oracle and MultiSig simultaneously** (they are independent):

```bash
source .env

# Deploy Oracle and MultiSig in parallel
forge script script/DeployOracle.s.sol:DeployOracle \
  --rpc-url "$RPC_URL" \
  --broadcast \
  --private-key "$PRIVATE_KEY" \
  --verify &
ORACLE_PID=$!

if [ -n "$MULTISIG_OWNERS" ]; then
    forge script script/DeployMultiSig.s.sol:DeployMultiSig \
      --rpc-url "$RPC_URL" \
      --broadcast \
      --private-key "$PRIVATE_KEY" \
      --verify &
    MULTISIG_PID=$!
    wait $ORACLE_PID $MULTISIG_PID
else
    echo "⚠️  MULTISIG_OWNERS not set in .env. Skipping MultiSig deployment."
    wait $ORACLE_PID
fi

source .env  # Reload addresses
```

#### Step 7: Deploy CCIP Sender/Receiver (if needed)

```bash
source .env

# If deploying custom CCIP endpoints
forge script script/DeployCCIPSender.s.sol:DeployCCIPSender \
  --rpc-url "$RPC_URL" \
  --broadcast \
  --private-key "$PRIVATE_KEY" \
  --verify
```

**Note**: All addresses are automatically saved to `.env` by the deployment scripts. Manual `.env` updates are only needed if using raw `forge script` commands.

### Method 3: Individual Contract Scripts

For deploying single contracts (can run multiple in parallel manually):

```bash
# Load .env first
source .env

# WETH9 only
make deploy-weth
# or
./scripts/deployment/deploy-weth.sh

# WETH10 only
make deploy-weth10
# or
./scripts/deployment/deploy-weth10.sh

# Deploy multiple contracts in parallel manually:
make deploy-weth &
make deploy-weth10 &
wait

# All WETH contracts with CCIP bridges (uses parallel internally where possible)
make deploy-weth-ccip
# or
./scripts/deployment/deploy-weth-with-ccip.sh

# Individual bridges (can deploy in parallel)
make deploy-ccip-weth9-bridge &
make deploy-ccip-weth10-bridge &
wait
```

---

## Configuration & Integration

### 1. Configure CCIP Bridges

After deploying bridges, configure them:

```bash
# Configure WETH9 Bridge
./scripts/deployment/configure-weth9-bridge.sh

# Configure WETH10 Bridge
./scripts/deployment/configure-weth10-bridge.sh
```

**Configuration includes**:
- Setting trusted destination chains
- Configuring fee tokens
- Setting up cross-chain message routing
- Whitelisting approved senders/receivers

### 2. Initialize Oracle

```bash
# Set up price feed
cast send $ORACLE_PROXY_ADDRESS \
  "submit(uint256)" \
  <price_in_wei> \
  --rpc-url $RPC_URL \
  --private-key $PRIVATE_KEY

# Example: Submit $2000 ETH/USD price (2000 * 10^8 = 200000000000)
cast send $ORACLE_PROXY_ADDRESS \
  "submit(uint256)" \
  200000000000 \
  --rpc-url $RPC_URL \
  --private-key $PRIVATE_KEY
```

### 3. Configure MultiSig

```bash
# Add owners
cast send $MULTISIG_ADDRESS \
  "addOwner(address)" \
  <owner_address> \
  --rpc-url $RPC_URL \
  --private-key $PRIVATE_KEY

# Set threshold (e.g., 2 of 3)
cast send $MULTISIG_ADDRESS \
  "changeThreshold(uint256)" \
  2 \
  --rpc-url $RPC_URL \
  --private-key $PRIVATE_KEY
```

### 4. Integrate with FireFly

Update FireFly configuration to use deployed contracts:

```yaml
# FireFly configuration
smart_contracts:
  weth9: "<WETH9_ADDRESS>"
  weth10: "<WETH10_ADDRESS>"
  oracle: "<ORACLE_PROXY_ADDRESS>"
  multisig: "<MULTISIG_ADDRESS>"
```

### 5. Configure Chainlink CCIP

If using Chainlink CCIP nodes, configure them:

```bash
# Update Chainlink node configuration
# Point to deployed CCIP Router
# Configure fee tokens
# Set up destination chains
```

---

## Testing & Verification

### 1. Verify Contract Deployments (Parallel)

**Use parallel verification for faster results:**

```bash
# Load .env first
source .env

# Verify all contracts in parallel (recommended - fastest)
./scripts/deployment/verify-contracts-parallel.sh

# Sequential verification (alternative)
./scripts/deployment/verify-on-chain-deployments.sh

# Check specific contracts (can run in parallel manually)
cast code "$WETH9_ADDRESS" --rpc-url "$RPC_URL" &
cast code "$WETH10_ADDRESS" --rpc-url "$RPC_URL" &
cast code "$CCIPWETH9BRIDGE_ADDRESS" --rpc-url "$RPC_URL" &
wait
```

### 2. Test WETH Contracts

```bash
# Test WETH9 deposit
cast send $WETH9_ADDRESS \
  "deposit()" \
  --value 1ether \
  --rpc-url $RPC_URL \
  --private-key $PRIVATE_KEY

# Test WETH9 withdrawal
cast send $WETH9_ADDRESS \
  "withdraw(uint256)" \
  1ether \
  --rpc-url $RPC_URL \
  --private-key $PRIVATE_KEY
```

### 3. Test CCIP Bridges

```bash
# Test cross-chain WETH9 transfer
# (Requires destination chain configuration)
cast send $CCIPWETH9BRIDGE_ADDRESS \
  "bridgeTokens(uint256,uint64,bytes)" \
  <amount> \
  <destination_chain_selector> \
  <recipient_address_bytes> \
  --rpc-url $RPC_URL \
  --private-key $PRIVATE_KEY \
  --value <ccip_fee>
```

### 4. Test Oracle

```bash
# Read latest price
cast call $ORACLE_PROXY_ADDRESS \
  "latestRoundData()" \
  --rpc-url $RPC_URL

# Submit price update
cast send $ORACLE_PROXY_ADDRESS \
  "submit(uint256)" \
  <price> \
  --rpc-url $RPC_URL \
  --private-key $PRIVATE_KEY
```

### 5. End-to-End Testing

```bash
# Run comprehensive tests
forge test --fork-url $RPC_URL -vvv

# Run integration tests
npm test  # If TypeScript/JavaScript tests exist
```

### 6. Monitor Contract Events

```bash
# Watch for deployment events
cast logs --from-block 0 \
  --address $WETH9_ADDRESS \
  --rpc-url $RPC_URL

# Watch CCIP bridge events
cast logs --from-block 0 \
  --address $CCIPWETH9BRIDGE_ADDRESS \
  --rpc-url $RPC_URL
```

## Troubleshooting

### Environment Configuration

**Problem**: Variables not found / scripts fail with "not set" errors  
**Solution**:
- Ensure `.env` file exists in project root: `ls -la .env`
- Load `.env` before running scripts: `source .env`
- Check variables are set: `grep PRIVATE_KEY .env`
- Use helper script to generate Phase 2 config: `./scripts/deployment/generate-phase2-tfvars.sh`

**Problem**: Duplicate variable definitions  
**Solution**:
- **All configuration should be in `.env` only** - don't duplicate in scripts or command line
- Remove hardcoded values from scripts
- Use `${VAR:-default}` syntax for optional variables
- Scripts automatically load `.env` - don't manually export variables

### Phase 2 Issues

**Problem**: Cannot SSH to VMs  
**Solution**: 
- Verify VPN/ExpressRoute/Cloudflare Tunnel connectivity
- Check NSG rules allow SSH from your IP
- Verify `SSH_PRIVATE_KEY_PATH` in `.env`: `grep SSH_PRIVATE_KEY_PATH .env`
- Regenerate terraform.tfvars: `./scripts/deployment/generate-phase2-tfvars.sh`

**Problem**: Docker compose services not starting  
**Solution**:
- Check logs: `docker compose logs` on VM
- Verify volumes exist: `ls -la /opt/*`
- Check permissions: `sudo chown -R besuadmin:besuadmin /opt/*`
- All regions deploy in parallel - check individual region: `./status.sh <region>`

### Contract Deployment Issues

**Problem**: Deployment fails with "insufficient funds"  
**Solution**: Fund deployer address with native tokens

**Problem**: CCIP Router deployment fails  
**Solution**: 
- Verify `CCIP_FEE_TOKEN` in `.env`: `grep CCIP_FEE_TOKEN .env`
- Use zero address for native token: `CCIP_FEE_TOKEN=0x0000000000000000000000000000000000000000`
- Check fee parameters (baseFee, dataFeePerByte) in deployment script
- Reload `.env`: `source .env`

**Problem**: Bridge deployment fails  
**Solution**:
- Verify `CCIP_ROUTER` is set in `.env`: `grep CCIP_ROUTER .env`
- Ensure `WETH9_ADDRESS` and `WETH10_ADDRESS` are in `.env`: `grep WETH.*ADDRESS .env`
- Check `CCIP_FEE_TOKEN` configuration in `.env`
- Deploy dependencies first (use parallel script which handles order automatically)

**Problem**: Parallel deployment failures  
**Solution**:
- Check individual contract deployments sequentially first
- Verify `.env` has all required addresses before parallel bridge deployment
- Use sequential script if parallel fails: `./scripts/deployment/deploy-contracts-ordered.sh`

## Support & Resources

- **Documentation**: `docs/` directory
- **Terraform Phase 1**: `terraform/phases/phase1/README.md`
- **Terraform Phase 2**: `terraform/phases/phase2/README.md`
- **Contract Documentation**: `contracts/README.md`
- **Deployment Scripts**: `scripts/deployment/README.md`
- **Environment Configuration**: `.env` file (create from `.env.example` if exists)

## Key Points: Using .env & Full Parallel Mode

1. **Single Source of Truth**: All configuration is in `.env` - no duplication
2. **Automatic Loading**: All scripts automatically `source .env`
3. **Auto-Updates**: Deployment scripts automatically update `.env` with deployed addresses
4. **Full Parallel Execution**: All independent operations run simultaneously:
   - Phase 2: All 5 regions deploy/start/stop/check in parallel
   - Contracts: Independent contracts deploy in parallel (Multicall, WETH9, WETH10, Oracle, MultiSig)
   - Bridges: Both bridge contracts deploy in parallel
   - Verification: All contracts verified in parallel
   - Testing: Forge tests use parallel execution (`-j $(nproc)`)
5. **No Manual Exports**: Don't manually export variables - scripts handle it
6. **Performance**: ~3-4x faster than sequential execution

### Quick .env Checklist

```bash
# Required variables
grep -E "^(PRIVATE_KEY|RPC_URL|CHAIN_ID|SSH_PRIVATE_KEY_PATH)=" .env

# Optional but recommended
grep -E "^(CCIP_ROUTER|CCIP_FEE_TOKEN|MULTISIG_OWNERS|ENVIRONMENT|VM_ADMIN_USERNAME)=" .env

# Verify .env is valid
source .env && echo "✅ .env loaded successfully"
```

---

## Complete Parallel Deployment (All-in-One)

### Master Script: Deploy Phase 2 + Contracts in Parallel

**For the fastest deployment, use the master parallel script:**

```bash
cd /home/intlc/projects/smom-dbis-138
source .env  # Ensure .env is loaded

# Deploy Phase 2 and contracts in full parallel mode
./scripts/deployment/deploy-phase2-and-contracts-parallel.sh
```

This script:
- Generates Phase 2 configuration from Phase 1 outputs and .env
- Deploys Phase 2 docker-compose to all 5 regions in parallel
- Starts Phase 2 services in parallel (all regions)
- Deploys all contracts in parallel (independent contracts simultaneously)
- Verifies both Phase 2 and contracts in parallel

**Performance**: Complete deployment in ~10-15 minutes (vs ~40 minutes sequential)

### Individual Parallel Operations

If you prefer step-by-step control:

```bash
# 1. Generate Phase 2 config (reads .env + Phase 1)
./scripts/deployment/generate-phase2-tfvars.sh

# 2. Deploy Phase 2 (all regions parallel)
cd terraform/phases/phase2 && terraform apply

# 3. Start services (all regions parallel)
./terraform/phases/phase2/scripts/start-services.sh all

# 4. Deploy contracts (parallel where possible)
source .env && ./scripts/deployment/deploy-contracts-parallel.sh

# 5. Verify everything (parallel)
./terraform/phases/phase2/scripts/status.sh all &
source .env && ./scripts/deployment/verify-contracts-parallel.sh &
wait
```
