• ✅ Transaction confirmation waiting
• ✅ Balance checking (ETH and tokens)

Key Features:

• Uses ChainID 138 RPC endpoints
• Supports private key signing
• Retry logic for transient failures
• Metrics recording for all transactions

File: services/onchain/blockchain.service.ts

• ✅ Database persistence tests (structure ready)

File: __tests__/integration/deal-execution.integration.test.ts

Test Coverage:

• Complete arbitrage loop
• Error handling
• State persistence
• Metrics recording
• Risk monitoring

---

7. Monitoring Dashboards ✅

Grafana Dashboard:

• ✅ Complete dashboard JSON configuration
• ✅ 11 panels covering all key metrics
• ✅ LTV monitoring with thresholds
• ✅ USDTz exposure tracking
• ✅ Profit visualization
• ✅ Transaction success rates
• ✅ Risk violations table

File: monitoring/grafana-dashboard.json

Panels Included:

1. Deals Executed (rate)
2. Deal Status Distribution (pie chart)
3. Current LTV Ratio (gauge with thresholds)
4. USDTz Exposure (graph)
5. Deal Duration (histogram)
6. Profit Captured (stat)
7. Transaction Success Rate (graph)
8. Risk Violations (table)
9. Active Deals (stat)
10. Error Rate (stat)
11. Gas Used (graph)
