### Security & Configuration
- [ ] Identify authorized wallet addresses for production
- [ ] Add wallet addresses to WALLET_ALLOWLIST in .env files
- [ ] Update Vault configuration if using dynamic allowlist
- [ ] Test transactions from allowed addresses (verify success)

## 🟢 Low Priority (Long-term)

### Metrics Collection
- [ ] Set up metrics collection system (Prometheus/Grafana recommended)
- [ ] Track RPC request rates by method (eth_chainId, eth_sendTransaction, etc.)
- [ ] Monitor response times (p50, p95, p99 percentiles)
- [ ] Track error rates by type (502, timeout, validation errors)
- [ ] Monitor transaction success rates for eth_sendTransaction
- [ ] Track nonce management metrics (locks, conflicts, retries)
- [ ] Monitor Web3Signer signing times and success rates
- [ ] Track Redis connection health and operation metrics

### Log Aggregation
- [ ] Set up centralized log aggregation system
- [ ] Configure log rotation and retention policies
- [ ] Implement structured logging (JSON format)
- [ ] Add log correlation IDs for request tracing
