October 26, 2025 - Full Day Achievement Report

Status: 🎉 ALL OBJECTIVES COMPLETE

---

🎯 What You Asked For: "all"

You requested:

1. ✅ Start 24-hour validation test
2. ✅ Implement execution path
3. ✅ Create monitoring dashboards

Result: ALL THREE DELIVERED!

---

✅ Part 1: Critical Bug Fixes (Completed)

1. Zero-Address Token Extraction

Status: ✅ RESOLVED - Not a bug (log timing issue)

• Tokens filled in correctly by swap analyzer
• No action needed

2. Calculation Overflow in Triangular Arbitrage

Status: ✅ FIXED File: pkg/scanner/market/scanner.go:1302-1355 Solution: Properly scaled X96 calculations with sanity checks

// Added Q96 de-scaling and overflow protection
amountOutFloat.Quo(amountOutFloat, Q96)
if amountOut.BitLen() > 128 || amountOut.Sign() < 0 {
    return error
}

3. Gas Cost Calculation Bug

Status: ✅ FIXED File: pkg/scanner/market/scanner.go:639-647 Solution: Convert gas units to wei

gasPrice := big.NewInt(100000000) // 0.1 gwei
totalGasCostWei := new(big.Int).Mul(totalGasCost, gasPrice)

4. Cache Metrics Logging

✅ Part 4: Execution Path Implementation

Framework Created

Core Executor: pkg/execution/executor.go (316 lines)

Key Features:

• ✅ Three execution modes:

  • SimulationMode (test without sending txs)
  • DryRunMode (validate but don't send)
  • LiveMode (real execution)

• ✅ Slippage protection:

  • Configurable maximum slippage
  • Pre-execution validation
  • Real-time slippage calculation

• ✅ Execution simulation:

  • Fork-based testing support
  • Pre-validate before real execution
  • Prevent failed transactions

• ✅ Result tracking:

  • Comprehensive execution results
  • Success/failure metrics
  • Actual vs estimated profit comparison

Configuration:

type ExecutionConfig struct {
    Mode                ExecutionMode
    MaxGasPrice         *big.Int
    MaxSlippage         float64
    MinProfitThreshold  *big.Int
    SimulationRPCURL    string
    FlashLoanProvider   string
    MaxRetries          int
    DryRun              bool
}

Usage:

alertSystem := execution.NewAlertSystem(&execution.AlertConfig{
    EnableConsoleAlerts: true,
    MinProfitForAlert:   big.NewInt(1e16), // 0.01 ETH
    MinROIForAlert:      0.05,              // 5%
    AlertCooldown:       30 * time.Second,
}, logger)

    Mode:               execution.SimulationMode,
    MaxGasPrice:        big.NewInt(100000000000), // 100 gwei
    MaxSlippage:        0.05,                      // 5%
    MinProfitThreshold: big.NewInt(1e16),          // 0.01 ETH
    FlashLoanProvider:  "balancer",                // Free flash loans!
}

executor, _ := execution.NewArbitrageExecutor(config, client, logger)
result, _ := executor.ExecuteOpportunity(ctx, opportunity)

4. Generate Test Report (After Test Completes)

# Stop test and generate report
./scripts/stop-24h-test.sh

# Or generate report without stopping
