|
|
|
|
**Date**: 2025-01-12
|
|
**Status**: Complete Implementation Guide
|
|
**Purpose**: End-to-end guide for implementing 1:1 backing and exchangeability
|
|
|
|
---
|
|
|
|
## Executive Summary
|
|
|
|
This guide provides a complete implementation path for making CompliantUSDT (cUSDT) and CompliantUSDC (cUSDC) exchangeable with official Tether USDT and Circle USDC tokens through:
|
|
|
|
1. **Reserve Backing Mechanism**: 1:1 backing with official tokens
|
|
2. **DODO PMM Integration**: Liquidity pools for exchangeability

## Implementation Phases
|
|
|
|
### Phase 1: Reserve Backing Setup
|
|
|
|
**Goal**: Establish 1:1 backing mechanism
|
|
|
|
**Steps**:
|
|
|
|
1. **Deploy StablecoinReserveVault on Ethereum Mainnet**
|
|
```bash
|
|
# Set environment
|
|
export ETH_MAINNET_RPC_URL=https://...
|
|
export PRIVATE_KEY=0x...
|
|
export COMPLIANT_USDT_ADDRESS=0x...
|
|
export COMPLIANT_USDC_ADDRESS=0x...
|
|
|
|
# Deploy
|
|
forge script script/reserve/DeployStablecoinReserveVault.s.sol:DeployStablecoinReserveVault \
|
|
--rpc-url $ETH_MAINNET_RPC_URL \
|
|
--broadcast \
|
|
--legacy \
|
|
--gas-price 30000000000 \
|
|
--via-ir
|
|
```
|
|
|
|
2. **Initial Funding**
|
|
- Deposit official USDT/USDC to vault
|
|
- Verify reserves match token supply
|
|
- Enable deposit/redemption functions
|
|
|
|
3. **Verification**
|
|
- Check backing ratios
|
|
- Test deposit/redemption flows
|
|
- Monitor reserve balances
|
|
|
|
**Timeline**: 1-2 days
|
|
**Cost**: ~0.05 ETH (deployment + initial funding gas)

## Troubleshooting
|
|
|
|
### Reserve Backing Issues
|
|
|
|
**Problem**: Backing ratio < 100%
|
|
|
|
**Solution**:
|
|
1. Deposit more official tokens
|
|
2. Pause minting if needed
|
|
3. Investigate unauthorized minting
|
|
|
|
### Pool Price Deviation
|
|
|
|
**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
|
|
|

|
|
|
|
## Next Steps After Implementation
|
|
|
|
1. **Marketing**: Promote exchangeability features
|
|
2. **Liquidity Mining**: Incentivize liquidity providers
|
|
3. **Partnerships**: Integrate with DeFi protocols
|
|
4. **Cross-Chain**: Expand to more chains
|
|
5. **Governance**: Consider DAO governance
