CHANGELOG.md

[0.2.0] - 2025-09-27

Added

• 🚀 MEV pipeline integration:
  • searcher.rs: detects arbitrage, sandwich, and liquidation opportunities from live txs
  • bundler.rs: builds MEV bundles and simulates submission to Flashbots, bloXroute, Eden
  • mempool.rs: orchestrates full detection-to-execution pipeline
• 🧪 --simulate mode for dry-run MEV testing (no actual bundle submission)
• 🎨 CLI enhancements:
  • --addr-style short|full for pretty address formatting
  • --color control for ANSI log output
  • --max-tx to cap number of txs processed
• 📦 Bundle tracking with UUIDs, gas estimates, and simulated inclusion probabilities
• 🔍 Transaction classification and decoding (Uniswap V2/V3, ERC20 transfers, etc.)
• 🧰 Scaffolding for configuration (types.rs::Config) and performance metrics (MEVMetrics)
• 🧱 Base structure for adding new DEXes, strategies, and real relay submission

Fixed

• 🐛 Compilation failure due to AddrStyle being moved in async logger
• 🧼 Clean startup flow with dotenv fallback and tracing initialization

Notes

• This release establishes the foundation for real MEV simulation and bundle orchestration.
• Future versions will include:
  • Integration test harness
  • Config + metrics usage
  • Live RPC interaction with relay APIs
  • Risk + profitability constraints
