|
5 | | -## Quick Start |
| 5 | +## Architecture |
| 6 | + |
| 7 | +Three staking contracts for different yield farming scenarios: |
| 8 | + |
| 9 | +1. **MigrationYieldFarm** - Epoch-based staking with migration incentives |
| 10 | +2. **RewardSeasonsYieldFarm** - Seasonal staking with snapshot-based rewards |
| 11 | +3. **LPYield/UniswapV3Staker** - LP position staking for Uniswap V3 |
| 12 | + |

| 129 | +forge test --match-test "*Security*" |
| 130 | +``` |
| 131 | + |
| 132 | +### Fork Testing |
| 133 | +LPYield tests use real Push Chain testnet fork and take longer due to network interaction. |

| 184 | +## Production Deployment |
| 185 | + |
| 186 | +### Pre-Deployment Checklist |
| 187 | +- [ ] Update merkle root in deployment scripts |
| 188 | +- [ ] Set correct owner address |
| 189 | +- [ ] Verify RPC endpoint and network |
| 190 | +- [ ] Test deployment on testnet first |
| 191 | +- [ ] Verify contract addresses on explorer |
| 192 | +- [ ] Test all admin functions |
| 193 | +- [ ] Verify merkle proof verification |
| 194 | + |
| 195 | +### Post-Deployment |
| 196 | +- [ ] Verify contract initialization |
| 197 | +- [ ] Test staking with valid merkle proofs |
| 198 | +- [ ] Test reward distribution |
| 199 | +- [ ] Test admin functions |
| 200 | +- [ ] Monitor for any issues |
| 201 | +- [ ] Document deployed addresses |
