Krypto Kajun 850223a953 fix(multicall): resolve critical multicall parsing corruption issues
- Added comprehensive bounds checking to prevent buffer overruns in multicall parsing
- Implemented graduated validation system (Strict/Moderate/Permissive) to reduce false positives
- Added LRU caching system for address validation with 10-minute TTL
- Enhanced ABI decoder with missing Universal Router and Arbitrum-specific DEX signatures
- Fixed duplicate function declarations and import conflicts across multiple files
- Added error recovery mechanisms with multiple fallback strategies
- Updated tests to handle new validation behavior for suspicious addresses
- Fixed parser test expectations for improved validation system
- Applied gofmt formatting fixes to ensure code style compliance
- Fixed mutex copying issues in monitoring package by introducing MetricsSnapshot
- Resolved critical security vulnerabilities in heuristic address extraction
- Progress: Updated TODO audit from 10% to 35% complete

Code Audit Preparation Plan

The goal is to methodically review each package and replace any stubbed, simulated, or placeholder implementations with production-ready logic. Use this tracker to record progress.

Review Cadence

  1. Select a package or subsystem.
  2. Catalogue all functions/structs that appear mocked, simulated, or simplified.
  3. Link to the source and note what the true production behaviour should be.
  4. Outline remediation steps (implementation, tests, docs, runbooks).
  5. Mark the item complete once merged and verified.

Initial Focus Areas

  • Arbitrage Execution (pkg/arbitrage/executor.go, pkg/arbitrage/flash_executor.go)
    • Simulation-only sections (mock transactions, gas estimation defaults).
    • TODO: Replace with real contract calls, gas oracle integration, and error handling covering on-chain responses.
  • Detection Engine (pkg/arbitrage/detection_engine.go)
    • Placeholder logging and simplified opportunity scoring.
    • TODO: Reconcile with production heuristics and ensure confidence calculations align with live data.
  • Metrics Server (pkg/metrics/metrics.go)
    • Confirm metrics cover end-to-end profitability, latency and error scenarios.
    • TODO: Validate against Prometheus/Grafana expectations and add missing labels if required.
  • Simulation Paths (pkg/arbitrage/executor.go simulation routines, tools/simulation vectors)
    • Ensure replay harness mirrors live execution paths and uses realistic inputs.
    • TODO: Gather historical vector captures and remove hard-coded assumptions.
  • Security/Staging Scripts (scripts/run.sh, deployment scripts)
    • Identify mocked secrets, rate limits, and incomplete hardening steps.
    • TODO: Replace with secure secret management integrations and production checks.

Tracking Table

Package / Module Status Notes
Arbitrage Executor [ ] Simulation paths rely on mocked gas estimation, fake receipts, and do not call real flash swap contracts (simulateFlashSwapArbitrage, executeFlashSwapArbitrage). Replace with production integrations, add on-chain error handling, and move simulation-only helpers under tests/examples.
FlashSwap Executor [ ] submitTransaction, waitForConfirmation, and createSuccessfulResult operate entirely on mock transactions/receipts; replace with actual contract bindings, receipt polling, and error handling.
Detection Engine Audit scoring heuristics vs. spec, implement production priorities.
Metrics Validate Prometheus labels and dashboards with SRE team.
Tooling: Simulation Gather live vectors, validate profit calculations, hook into CI.
Scripts: Deployment Harden secrets handling, document rollback plans.
