||||
|
||||
**Problem**: Pool price deviates from $1
|
||||
|
||||
**Solution**:
|
||||
1. Check pool reserves balance
|
||||
2. Add/remove liquidity as needed
|
||||
3. Monitor for large trades
|
||||
4. Allow arbitrage to correct
|
||||
|
||||
### Liquidity Issues
|
||||
|
||||
**Problem**: Insufficient liquidity for swaps
|
||||
|
||||
**Solution**:
|
||||
1. Add more liquidity to pools
|
||||
2. Adjust k factor if needed
|
||||
3. Incentivize LPs if necessary

DODO PMM Integration enables liquidity pools between CompliantUSDT (cUSDT)/CompliantUSDC (cUSDC) and official USDT/USDC tokens. This provides:
|
||||
|
||||
- **Exchangeability**: Users can swap between compliant and official tokens
|
||||
- **Price Stability**: PMM algorithm maintains 1:1 peg
|
||||
- **Liquidity**: Efficient capital utilization
|
||||
- **Arbitrage Opportunities**: Market-driven peg maintenance
|
||||
|
||||

|
||||
|
||||
## Architecture
|
||||
|
||||
### Contract: DODOPMMIntegration
|
||||
|
||||
**Location**: `contracts/dex/DODOPMMIntegration.sol`
|
||||
|
||||
**Purpose**:
|
||||
- Create and manage DODO PMM pools
|
||||
- Facilitate swaps between compliant and official tokens
|
||||
- Manage liquidity provision
|
||||
|
||||
**Key Features**:
|
||||
- Pool creation (cUSDT/USDT, cUSDC/USDC)
|
||||

## DODO PMM Overview
|
||||
|
||||
### Proactive Market Maker (PMM)
|
||||
|
||||
DODO's PMM algorithm:
|
||||
- Uses external price oracles (TWAP)
|
||||
- Maintains price stability through automated market making
|
||||
- More capital efficient than traditional AMMs
|
||||
- Lower slippage for stablecoin pairs
|
||||
|
||||
### Pool Types
|
||||
|
||||
**DODO Vending Machine (DVM)**:
|
||||
- Most common for custom pairs
|
||||
- Supports single-sided liquidity provision
|
||||
- Better for stablecoin pairs
|
||||
|
||||
**Key Parameters**:
|
||||
- `i`: Initial price (1e18 = $1 for stablecoins)
|
||||
- `k`: Slippage factor (lower = less slippage, 0.5e18 recommended)
|
||||
- `lpFeeRate`: LP fee in basis points (3 = 0.03%)
|
||||
- `isOpenTWAP`: Enable time-weighted average price oracle
|
||||

## Pool Parameters Guide
|
||||
|
||||
### Initial Price (`i`)
|
||||
|
||||
- **Value**: `1000000000000000000` (1e18)
|
||||
- **Meaning**: $1 for stablecoin pairs
|
||||
- **Adjustment**: Can set different initial price if needed
|
||||
|
||||
### K Factor (`k`)
|
||||
|
||||
- **Range**: 0 to 1e18
|
||||
- **Recommended**: `500000000000000000` (0.5e18 = 50%)
|
||||
- **Lower k**: Less slippage, more capital intensive
|
||||
- **Higher k**: More slippage, less capital intensive
|
||||
- **For stablecoins**: Lower k (0.3-0.5) recommended
|
||||
|
||||
### LP Fee Rate
|
||||
|
||||
- **Unit**: Basis points (100 = 1%)
|
||||
- **Recommended**: 3-10 basis points (0.03% - 0.1%)
|
||||
- **Lower fee**: More attractive for traders
|
||||
- **Higher fee**: More revenue for LPs
|
||||
|
||||
### TWAP Oracle
|
||||

|
||||
|
||||
## Integration Workflow
|
||||
|
||||
### Phase 1: Setup
|
||||
|
||||
1. Deploy DODOPMMIntegration contract
|
||||
2. Create pools (cUSDT/USDT, cUSDC/USDC)
|
||||
3. Configure pool parameters
|
||||
|
||||
### Phase 2: Seed Liquidity
|
||||
|
||||
1. Approve tokens to integration contract
|
||||
2. Add initial liquidity to pools
|
||||
3. Monitor pool reserves and prices
|
||||
|
||||
### Phase 3: Enable Trading
|
||||
|
||||
1. Open pools for public trading
|
||||
2. Monitor swap volumes
|
||||
3. Adjust parameters if needed
|
||||
|
||||
### Phase 4: Maintenance
|
||||
|
||||
1. Monitor pool health
|
||||
2. Add/remove liquidity as needed
|
||||
3. Update parameters for optimization
|
||||
|
||||
---
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Liquidity Depth**: Maintain sufficient liquidity for expected volume
|
||||
2. **Price Monitoring**: Monitor pool prices vs. 1:1 peg
|
||||
3. **Arbitrage**: Allow arbitrageurs to maintain peg
|
||||
4. **Slippage Protection**: Use appropriate slippage tolerances
|
||||
5. **Gas Optimization**: Use DODO Approve for batch operations
|
||||
6. **Security**: Audit contracts before mainnet deployment
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Pool Creation Fails
|
||||
|
||||
- Check DODO Vending Machine address is correct
|
||||
- Verify token addresses are valid
|
||||
- Ensure sufficient gas
|
||||
|
||||
### Swaps Failing
|
||||
|
||||
- Check pool has sufficient liquidity
|
||||
- Verify slippage tolerance is appropriate
|
||||
- Check token approvals
|
||||
|
||||
### Price Deviation
|
||||
|
||||
- Check pool reserves are balanced
|
||||
- Monitor for large trades
|
||||
- Consider adding/removing liquidity
|
||||
|
||||

|
||||
2. Create pools with optimal parameters
|
||||
3. Seed initial liquidity
|
||||
4. Enable trading
|
||||
5. Monitor and optimize

|
||||
Provides 1:1 backing for compliant tokens with official USDT/USDC:
|
||||
- Locks official tokens on Ethereum Mainnet
|
||||
- Mints compliant tokens 1:1
|
||||
- Enables redemption for official tokens
|
||||
|
||||
### DODO PMM Integration
|
||||
|
||||
Creates liquidity pools for exchangeability:
|
||||
- cUSDT ↔ USDT pools
|
||||
- cUSDC ↔ USDC pools
|
||||
- Price stability via PMM algorithm
|
||||
- Efficient liquidity management

|
||||
|
||||
## Overview
|
||||
|
||||
The Reserve Backing Mechanism enables CompliantUSDT (cUSDT) and CompliantUSDC (cUSDC) to maintain 1:1 backing with official Tether USDT and Circle USDC tokens. This provides transparency, trust, and exchangeability with official stablecoins.
|
||||
|
||||
---
|
||||
|
||||
## Architecture
|
||||
|
||||
### Contract: StablecoinReserveVault
|
||||
|
||||
**Location**: `contracts/reserve/StablecoinReserveVault.sol`
|
||||
|
||||
**Purpose**:
|
||||
- Lock official USDT/USDC tokens
|
||||
- Mint cUSDT/cUSDC tokens 1:1 against locked reserves
|
||||
- Enable redemption of cUSDT/cUSDC for official tokens
|
||||
|
||||
**Key Features**:
|
||||
- 1:1 minting ratio (1 official token = 1 compliant token)
|
||||
- Reserve tracking and verification
|
||||
- Pause mechanism for emergencies
|
||||
- Access control with role-based permissions

|
||||
|
||||
## Operations
|
||||
|
||||
### Deposit and Mint
|
||||
|
||||
Users can deposit official tokens and receive compliant tokens 1:1.
|
||||
|
||||
#### Deposit USDT → Mint cUSDT
|
||||
|
||||
```bash
|
||||
# 1. Approve USDT to vault
|
||||
cast send $OFFICIAL_USDT_ADDRESS \
|
||||
"approve(address,uint256)" \
|
||||
$STABLECOIN_RESERVE_VAULT_ADDRESS \
|
||||
1000000000000 \
|
||||
--rpc-url $ETH_MAINNET_RPC_URL \
|
||||
--private-key $PRIVATE_KEY \
|
||||
--gas-price 30000000000 \
|
||||
--legacy
|
||||
|
||||
# 2. Deposit USDT (amount in base units with 6 decimals)
|
||||
# Example: 1,000,000 USDT = 1000000000000 (1e12)
|
||||
cast send $STABLECOIN_RESERVE_VAULT_ADDRESS \
|
||||
"depositUSDT(uint256)" \
|
||||
1000000000000 \
|
||||
--rpc-url $ETH_MAINNET_RPC_URL \
|
||||
--private-key $PRIVATE_KEY \
|
||||
--gas-price 30000000000 \
|
||||
--legacy
|
||||
```
|
||||
|
||||
#### Deposit USDC → Mint cUSDC
|
||||
|
||||
Similar process for USDC:
|
||||
|
||||
```bash
|
||||
# Approve and deposit
|
||||
cast send $OFFICIAL_USDC_ADDRESS \
|
||||
"approve(address,uint256)" \
|
||||
$STABLECOIN_RESERVE_VAULT_ADDRESS \
|
||||
1000000000000 \
|
||||
--rpc-url $ETH_MAINNET_RPC_URL \
|
||||
--private-key $PRIVATE_KEY \
|
||||
--gas-price 30000000000 \
|
||||
--legacy
|
||||
|
||||
cast send $STABLECOIN_RESERVE_VAULT_ADDRESS \
|
||||
"depositUSDC(uint256)" \
|
||||
1000000000000 \
|
||||
--rpc-url $ETH_MAINNET_RPC_URL \
|
||||
--private-key $PRIVATE_KEY \
|
||||
--gas-price 30000000000 \
|
||||
--legacy
|
||||
```
|
||||
|
||||
### Redemption
|
||||
|
||||
Users can redeem compliant tokens for official tokens 1:1.
|
||||
|
||||
#### Redeem cUSDT → Receive USDT
|
||||
|
||||
```bash
|
||||
cast send $STABLECOIN_RESERVE_VAULT_ADDRESS \
|
||||
"redeemUSDT(uint256)" \
|
||||
1000000000000 \
|
||||
--rpc-url $ETH_MAINNET_RPC_URL \
|
||||
--private-key $PRIVATE_KEY \
|
||||
--gas-price 30000000000 \
|
||||
--legacy
|
||||
```
|
||||
|
||||
#### Redeem cUSDC → Receive USDC
|
||||
|
||||
```bash
|
||||
cast send $STABLECOIN_RESERVE_VAULT_ADDRESS \
|
||||
"redeemUSDC(uint256)" \
|
||||
1000000000000 \
|
||||
--rpc-url $ETH_MAINNET_RPC_URL \
|
||||
--private-key $PRIVATE_KEY \
|
||||
--gas-price 30000000000 \
|
||||
--legacy
|
||||
```
|
||||
|
||||
### Verification
|
||||
|
||||
#### Check Reserve Balances
|
||||
|
||||
```bash
|
||||
# USDT reserve
|
||||
cast call $STABLECOIN_RESERVE_VAULT_ADDRESS "usdtReserveBalance()" --rpc-url $ETH_MAINNET_RPC_URL | cast --to-dec
|
||||
|
||||
# USDC reserve
|
||||
cast call $STABLECOIN_RESERVE_VAULT_ADDRESS "usdcReserveBalance()" --rpc-url $ETH_MAINNET_RPC_URL | cast --to-dec
|
||||
```
|
||||
|
||||
#### Check Backing Ratio
|
||||
|
||||
```bash
|
||||
# For cUSDT
|
||||
cast call $STABLECOIN_RESERVE_VAULT_ADDRESS \
|
||||
"getBackingRatio(address)" \
|
||||
$COMPLIANT_USDT_ADDRESS \
|
||||
--rpc-url $ETH_MAINNET_RPC_URL
|
||||
|
||||
# Returns: (reserveBalance, tokenSupply, backingRatio)
|
||||
# backingRatio = 10000 means 100% backed
|
||||
```
|
||||
|
||||
#### Check Reserve Adequacy
|
||||
|
||||
```bash
|
||||
cast call $STABLECOIN_RESERVE_VAULT_ADDRESS "checkReserveAdequacy()" --rpc-url $ETH_MAINNET_RPC_URL
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Access Control
|
||||
|
||||
### Roles
|
||||
|
||||
- **DEFAULT_ADMIN_ROLE**: Can pause/unpause, emergency withdraw
|
||||
- **RESERVE_OPERATOR_ROLE**: Can manage reserves (currently same as admin)
|
||||
- **REDEMPTION_OPERATOR_ROLE**: Can process redemptions (currently same as admin)
|
||||
|
||||
### Pause Mechanism
|
||||
|
||||
```bash
|
||||
# Pause all operations
|
||||
cast send $STABLECOIN_RESERVE_VAULT_ADDRESS \
|
||||
"pause()" \
|
||||
--rpc-url $ETH_MAINNET_RPC_URL \
|
||||
--private-key $PRIVATE_KEY \
|
||||
--gas-price 30000000000 \
|
||||
--legacy
|
||||
|
||||
# Unpause
|
||||
cast send $STABLECOIN_RESERVE_VAULT_ADDRESS \
|
||||
"unpause()" \
|
||||
--rpc-url $ETH_MAINNET_RPC_URL \
|
||||
--private-key $PRIVATE_KEY \
|
||||
--gas-price 30000000000 \
|
||||
--legacy
|
||||
```
|
||||
|
||||
### Emergency Withdrawal
|
||||
|
||||
```bash
|
||||
# Can only be called when paused
|
||||
cast send $STABLECOIN_RESERVE_VAULT_ADDRESS \
|
||||
"emergencyWithdraw(address,uint256,address)" \
|
||||
$OFFICIAL_USDT_ADDRESS \
|
||||
<amount> \
|
||||
<recipient> \
|
||||
--rpc-url $ETH_MAINNET_RPC_URL \
|
||||
--private-key $PRIVATE_KEY \
|
||||
--gas-price 30000000000 \
|
||||
--legacy
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Security Considerations
|
||||
|
||||
1. **1:1 Backing**: Always maintain reserves >= token supply
|
||||
2. **Access Control**: Use multi-sig for admin role in production
|
||||
3. **Pause Mechanism**: Test pause/unpause functionality
|
||||
4. **Emergency Procedures**: Have emergency withdrawal plan
|
||||
5. **Audit**: Conduct security audit before mainnet deployment
|
||||
6. **Monitoring**: Monitor reserve balances and backing ratios
|
||||
|
||||

|
||||
|
||||
## Integration with Cross-Chain Bridge
|
||||
|
||||
For Chain 138 deployment, integrate with cross-chain bridge:
|
||||
|
||||
1. Deploy vault on Ethereum Mainnet
|
||||
2. Connect to Chain 138 via bridge (CCIP or custom bridge)
|
||||
3. Bridge operations:
|
||||
- Lock official tokens on Mainnet → Mint cUSDT/cUSDC on Chain 138
|
||||
- Burn cUSDT/cUSDC on Chain 138 → Unlock official tokens on Mainnet
|
||||
|
||||
---
|
||||
|
||||
## Example Usage Script
|
||||
|
||||
See `scripts/setup-reserve-vault.sh` for automated setup and verification.
|
||||
|
||||
---
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. Deploy vault contract
|
||||
2. Fund with initial reserves
|
||||
3. Enable deposits
|
||||
4. Monitor backing ratios
|
||||
5. Integrate with DODO PMM pools for exchangeability
