MEV Bot Project Specification
🎯 Project Overview
The MEV Bot is a production-ready arbitrage detection and analysis system for the Arbitrum network. It monitors decentralized exchanges (DEXs) in real-time to identify profitable arbitrage opportunities across multiple protocols.
✅ Current Implementation Status
Core Features (Production Ready)
- Real-time Arbitrum Monitoring: Monitors sequencer with sub-second latency
- Multi-DEX Support: Uniswap V2/V3, SushiSwap, Camelot, Curve Finance, and more
- Advanced ABI Decoding: Comprehensive multicall transaction parsing
- Transaction Pipeline: High-throughput processing with 50,000 transaction buffer
- Connection Management: Automatic RPC failover and health monitoring
- Arbitrage Detection: Configurable threshold detection (0.1% minimum spread)
- Security Framework: AES-256-GCM encryption and secure key management
- Monitoring & Metrics: Prometheus integration with structured logging
