(Blocking Production) + +### 1. **No Integration** ⚠️ HIGH PRIORITY +- ❌ Components exist in separate feature branches +- ❌ No main application that connects everything +- ❌ No end-to-end integration tests +- ❌ Branches not merged to master + +**Impact:** Cannot run the bot at all + +### 2. **No Sequencer Integration** ⚠️ CRITICAL +- ❌ No Arbitrum sequencer reader +- ❌ No WebSocket connection to pending transactions +- ❌ No real-time transaction stream processing +- ❌ Missing the **core competitive advantage** + +**Impact:** Bot will be too slow to be profitable + +### 3. **No Pool Discovery** ⚠️ HIGH PRIORITY +- ❌ Cache is empty at startup +- ❌ No mechanism to discover existing pools +- ❌ No pool state synchronization +- ❌ Cannot detect opportunities without pool data + +**Impact:** Bot has no pools to arbitrage + +### 4. **No Real Configuration** ⚠️ MEDIUM PRIORITY +- ❌ Hardcoded values in code +- ❌ No environment-based configuration +- ❌ No secrets management +- ❌ No RPC endpoint configuration + +**Impact:** Cannot deploy to production safely + +### 5. **No Monitoring/Alerting** ⚠️ MEDIUM PRIORITY +- ❌ Metrics defined but not exposed +- ❌ No Prometheus/Grafana integration +- ❌ No alerting on failures +- ❌ No profitability tracking + +**Impact:** Cannot monitor bot performance + +### 6. **No Wallet Management** ⚠️ HIGH PRIORITY +- ❌ No secure key storage +- ❌ No balance monitoring +- ❌ No gas reserve management +- ❌ Hardcoded private keys + +**Impact:** Security risk, cannot manage funds + +--- + +## 🎯 **MITIGATION PLAN** (Path to Production) + +###
