- Deployment checklist

## Extensibility (Never Box In)

7 mechanisms to prevent architectural lock-in:
1. Plugin Architecture - Add asset types without core changes
2. Upgradeable Contracts - UUPS proxies
3. Registry-Based Config - No hardcoded addresses
4. Modular Bridges - Asset-specific contracts
5. Composable Compliance - Stackable modules
6. Multi-Source Liquidity - Pluggable providers
7. Event-Driven - Loose coupling

## Statistics

- Contracts: 30+ created (~5,000+ LOC)
- Asset Types: 10+ supported (infinitely extensible)
- Tests: 5+ files (integration, security, fuzzing)
- Documentation: 8+ files (architecture, guides, security)
- Deployment Scripts: 5 files
- Extensibility Mechanisms: 7

## Result

A future-proof system supporting:
- ANY asset type (tokens, GRU, eMoney, CBDCs, securities, commodities, RWAs)
- ANY chain (EVM + future non-EVM via CCIP)
- WITH governance (hybrid risk-based approval)
- WITH liquidity (PMM integrated)
- WITH compliance (built-in modules)
- WITHOUT architectural limitations

Add carbon credits, real estate, tokenized bonds, insurance products,
or any future asset class via plugins. No redesign ever needed.

K Factor 0.3e18 - 0.5e18 Lower = less slippage
LP Fee Rate 3-10 bps 0.03% - 0.1%
TWAP Enabled Price stability
Initial Liquidity 1M+ tokens For each pool

Security Considerations

Reserve Vault

  1. Multi-sig Admin: Use multi-sig wallet for admin role
  2. Access Control: Limit operator roles
  3. Pause Mechanism: Test emergency pause
  4. Audit: Professional security audit
  5. Monitoring: Real-time reserve monitoring

DODO Pools

  1. Pool Parameters: Carefully set k and fees
  2. Liquidity Depth: Maintain sufficient liquidity
  3. Price Monitoring: Monitor for manipulation
  4. Slippage Protection: Use appropriate limits
  5. Emergency Procedures: Plan for pool issues

Monitoring & Maintenance

Key Metrics

    • Token supply (cUSDT/cUSDC)
    • Backing ratio (target: 100%+)
    • Deposit/redemption volumes
  2. DODO Pools:

    • Pool reserves (base/quote)
    • Pool price vs. peg
    • Swap volumes
    • LP fee accumulation
    • Slippage rates

Monitoring Tools

  • Custom dashboards (Grafana, etc.)
  • On-chain monitoring (The Graph, etc.)
  • Alert systems (PagerDuty, etc.)
  • Automated scripts (check reserves, etc.)

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
