## Daily Operations

### 1. System Health Checks

```bash
# Check all services
./scripts/verify-deployment.sh

# Check service logs
docker logs liquidity-engine-service --tail 100
docker logs market-reporting-service --tail 100

# Check contract status
cast call $LIQUIDITY_POOL "totalLiquidity()" --rpc-url $ETHEREUM_MAINNET_RPC
```

### 2. Monitor Bridge Activity

```bash
# Check recent deposits
cast logs --from-block latest-1000 \
  --address $LOCKBOX_138 \
  "DepositCreated(uint256,address,uint256)" \
  --rpc-url $RPC_URL_138

# Check recent claims
cast logs --from-block latest-1000 \
  --address $INBOX_ETH \
  "ClaimSubmitted(uint256,address,uint256)" \
  --rpc-url $ETHEREUM_MAINNET_RPC
```

### 3. Monitor Peg Status

```bash
# Check USD peg
cast call $STABLECOIN_PEG_MANAGER \
  "checkUSDpeg(address)" \
  $USDT \
  --rpc-url $ETHEREUM_MAINNET_RPC

# Check ETH peg
cast call $STABLECOIN_PEG_MANAGER \
  "checkETHpeg(address)" \
  $WETH \
  --rpc-url $ETHEREUM_MAINNET_RPC
```

## Monitoring

### Key Metrics to Monitor

1. **Liquidity Pool Balance**
   - Minimum: 100 ETH
   - Alert threshold: 50 ETH

2. **Reserve Ratio**
   - Target: 110%+
   - Alert threshold: 105%

3. **Peg Deviations**
   - USD stablecoins: ±0.5%
   - ETH/WETH: ±0.1%
   - Commodities: ±1.0%

4. **Bridge Volume**
   - Daily volume tracking
   - Average transaction size
   - Peak usage times

5. **Service Health**
   - API response times
   - Error rates
   - Service uptime

### Setting Up Alerts

```bash
# Example: Monitor liquidity pool
watch -n 60 'cast call $LIQUIDITY_POOL "totalLiquidity()" --rpc-url $ETHEREUM_MAINNET_RPC'
```

## Maintenance Tasks

### Weekly Tasks

1. **Review Bridge Metrics**
   - Analyze transaction patterns
   - Check for anomalies
   - Review service logs

2. **Update Price Feeds**
   - Verify oracle prices
   - Update commodity rates if needed
   - Check ISO currency rates

3. **Liquidity Management**
   - Assess liquidity needs
   - Add/remove liquidity as needed
   - Rebalance if necessary

### Monthly Tasks

1. **Security Audit**
   - Review access control
   - Check for unauthorized access
   - Verify contract permissions

2. **Performance Review**
   - Analyze gas costs
   - Optimize routing if needed
   - Review service performance

3. **Documentation Update**
   - Update operational procedures
   - Document incidents
   - Review and update runbooks

## Emergency Procedures

### 1. Pause Bridge Operations

```bash
# Pause liquidity pool (if pause function exists)
cast send $LIQUIDITY_POOL \
  "pause()" \
  --rpc-url $ETHEREUM_MAINNET_RPC \
  --private-key $PRIVATE_KEY
```

### 2. Emergency Withdrawal

```bash
# Withdraw liquidity (if emergency withdrawal exists)
cast send $LIQUIDITY_POOL \
  "emergencyWithdraw()" \
  --rpc-url $ETHEREUM_MAINNET_RPC \
  --private-key $PRIVATE_KEY
```

### 3. Update Configuration

```bash
# Update routing configuration
cast send $ENHANCED_SWAP_ROUTER \
  "setRoutingConfig(uint256,uint8[])" \
  0 \
  "[0,2]" \
  --rpc-url $ETHEREUM_MAINNET_RPC \
  --private-key $PRIVATE_KEY
```

## Troubleshooting

### Common Issues

1. **Service Not Responding**
   ```bash
   # Restart service
   docker restart liquidity-engine-service
   
   # Check logs
   docker logs liquidity-engine-service --tail 100
   ```

2. **High Gas Costs**
   - Review routing configuration
   - Consider using different DEX protocols
   - Optimize swap routes

3. **Peg Deviation**
   - Check oracle prices
   - Trigger rebalancing if needed
   - Review reserve status

4. **Insufficient Liquidity**
   - Add liquidity to pool
   - Check reserve system
   - Review bridge volume

### Getting Help

1. Check logs: `docker logs <service-name>`
2. Review documentation: `docs/bridge/trustless/`
3. Check contract status: `./scripts/verify-deployment.sh`
4. Contact support team

## Next Steps

- Set up automated monitoring
- Configure alerting system
- Train operations team
- Establish incident response procedures
