MEV Bot Master Plan Summary & Roadmap
Project Summary
This master plan outlines the comprehensive implementation of exchange-specific helper libraries for the MEV bot. The project encompasses support for multiple DEX protocols including Uniswap, SushiSwap, Curve, Balancer, PancakeSwap, and DEX aggregators, with advanced cross-exchange arbitrage capabilities.
Project Scope
Core Components
- Common interface definitions for all exchanges
- Exchange-specific implementation modules
- Cross-exchange arbitrage detection
- Pricing and liquidity management
- Testing and deployment infrastructure
Supported Exchanges
- Uniswap (V2/V3)
- SushiSwap
- Curve Finance
- Balancer
- PancakeSwap
- DEX Aggregators (1inch, ParaSwap, etc.)
Implementation Roadmap
Phase 1: Foundation (Weeks 1-2)
- Define common interfaces
- Set up project structure in
docs/master-plan/ - Create core documentation
- Implement base exchange module
Phase 2: Core Exchange Support (Weeks 3-6)
- Implement Uniswap V2/V3/V4 modules
- Implement SushiSwap module
- Basic Curve integration
- Unit tests for core exchanges
Phase 3: Advanced Exchanges (Weeks 7-9)
- Implement Balancer module
- Implement PancakeSwap module
- Implement Kyber module
- DEX aggregator integration
- Cross-chain functionality
Phase 4: Arbitrage & Optimization (Weeks 10-12)
- Cross-exchange arbitrage implementation
- Performance optimization
- Security hardening
- Documentation completion
Phase 5: Deployment & Operations (Weeks 13-14)
- Staging deployment
- Production deployment
- Monitoring setup
- Final testing and validation
