MEV Bot Production Audit & Remediation Plan

Date: November 6, 2025 Status: IN PROGRESS - Comprehensive Audit Priority: CRITICAL - Ensure 100% production readiness

---

Audit Scope

1. Test Coverage & Quality 🧪

• Run full test suite: podman compose up test-unit
• Generate coverage report: podman compose up test-coverage
• Identify failing tests
• Identify uncovered code paths
• Ensure 100% coverage target
• Fix all failing tests

2. Code Quality & Security 🔒

• Run security scan: podman compose up test-security
• Run linting: podman compose up test-lint
• Check for hardcoded secrets
• Verify error handling completeness
• Review input validation
• Check for SQL injection/code injection

3. Profitability & Trading Logic 💰

Files to audit:

• pkg/arbitrage/detection_engine.go - Opportunity detection
• pkg/profitcalc/profit_calc.go - Profit calculation
• pkg/scanner/swap/analyzer.go - Swap analysis
• pkg/tokens/metadata_cache.go - Token metadata handling
• cmd/mev-bot/main.go - Main bot entry point

Key checks:

• Threshold configuration (0.1% minimum)
• Profit calculation accuracy
• Gas estimation correctness
• Slippage handling
• Flash loan integration
• Multi-hop detection
• Price impact calculations

4. Integration & Production Config ⚙️

• RPC endpoint configuration
• Rate limiting settings
• Connection pooling
• Error recovery mechanisms
• Health checks
• Logging completeness
• Monitoring setup

5. Make Commands Optimization 🔨

• Verify all make commands work
• Check Podman integration in all CI/CD targets
• Ensure caching is optimized
• Test incremental builds

6. Dockerfile & Container Optimization 📦

• Multi-stage build efficiency
• Layer caching optimization
• Image size optimization
• Security: non-root user
• Base image selection

Audit Checklist

Phase 1: Testing (Current)

# Run all test suites
podman compose -f docker-compose.test.yml up test-unit
podman compose -f docker-compose.test.yml up test-coverage
podman compose -f docker-compose.test.yml up test-security
podman compose -f docker-compose.test.yml up test-lint

# Generate reports
make test-coverage
make audit-full

Phase 2: Code Review

• Review trading logic for correctness
• Verify mathematical precision (no floating point errors)
• Check edge case handling
• Validate RPC error handling
• Review goroutine management
• Check memory leaks potential

Phase 3: Integration Testing

• Test with mock RPC endpoints
• Verify transaction building
• Test error scenarios
• Validate recovery mechanisms
• Check connection stability

Phase 4: Performance Testing

• Measure transaction processing latency
• Check memory usage under load
• Verify CPU usage
• Test concurrent request handling
• Measure opportunity detection speed

Critical Issues to Investigate

1. Test Failures

• Current: Status unknown (tests running)
• Action: Analyze and fix all failures

2. Code Coverage

• Target: 100%
• Current: Unknown
• Action: Identify and test uncovered paths

3. Trading Logic Issues

Key concerns:

• Is opportunity detection working?
• Are we correctly calculating profits?
• Are gas costs properly estimated?
• Is slippage being handled?
• Are flash loans integrated?

4. Production Configuration

• RPC rate limiting
• Connection pooling
• Error recovery
• Health checks
• Monitoring

5. Make Commands

Verify these work with Podman:

• make build ✅
• make test ⏳
• make test-coverage ⏳
• make ci-container ⏳
• make audit-full ⏳

---

Remediation Plan (If Issues Found)

For Failing Tests:

1. Analyze failure root cause
2. Create minimal test case
3. Fix underlying code issue
4. Add regression test
5. Verify fix passes all related tests

For Coverage Gaps:

1. Identify uncovered code paths
2. Create test case for path
3. Add edge case tests
4. Verify coverage increases to 100%

For Trading Logic Issues:

1. Review algorithm correctness
2. Add unit tests for calculations
3. Add integration tests with mock data
4. Validate against expected outputs
5. Test edge cases (zero amounts, extreme prices, etc.)

For Production Config Issues:

1. Review configuration files
2. Add validation logic
3. Create integration tests
4. Document all settings
5. Create example configs
