DEX Aggregator Integration Plan
Overview
This document outlines the implementation plan for integrating with DEX aggregators in the MEV bot. DEX aggregators source liquidity from multiple exchanges to provide better prices and lower slippage.
Major DEX Aggregators
1inch
- Contract:
0x1111111254fb6c44bAC0beD2854e76F90643097d(mainnet) - Features: Multi-chain support, gas estimation, complex routing
ParaSwap
- Contract:
0xDEF171Fe48CF0115B1d80b88dc8eAB59176FEe57 - Features: Open-source API, multiple DEX support, price optimization
Matcha (0x)
- Contract: Various proxy contracts
- Features: Multi-DEX integration, API support, MEV protection
OpenOcean
- Features: Cross-chain aggregation, gasless swaps
- Contract: Multiple chain-specific contracts
Core Functions
Swap Functions
swap(executing trades)unoswap(1inch specific)multiswap(multi-hop routing)buy(for reverse trades)
Quote Functions
getRate(price estimation)getAmountsOut(with multi-DEX routing)getSwapCalldata(for simulation)
Aggregation Functions
- Route optimization across multiple DEXs
- Gas cost comparison
- Price impact minimization
Implementation Steps
- Create Aggregator struct implementing the Exchange interface
- Implement 1inch aggregation functionality
- Add ParaSwap integration
- Integrate Matcha/0x
- Add OpenOcean support
- Implement routing optimization algorithm
- Create gas estimation functions
- Add multi-chain support
Pricing Mechanisms
Multi-DEX Routing
- Compare prices across multiple exchanges
- Consider gas costs in profitability
- Account for slippage across different platforms
- Optimize route based on total cost (swap + gas)
Aggregation-Specific Considerations
- Split trades across multiple DEXs to reduce slippage
- Consider front-running protection
- Account for different fee structures
- Evaluate MEV protection mechanisms
Testing Plan
- Unit tests for each aggregator integration
- Price comparison accuracy testing
- Route optimization verification
- Gas estimation accuracy testing
- Multi-hop trade execution testing
- Edge case testing (large trades, multiple splits)
- Cross-chain functionality testing
- Performance comparison with direct DEX swaps
Performance Considerations
- Optimize for lowest possible slippage
- Minimize gas costs across all operations
- Efficient routing algorithms
- Cache commonly used routes
- Batch operations where possible
- Consider transaction complexity limits
Security Considerations
- Validate aggregator contract addresses
- Implement proper slippage protection
- Verify routing safety
- Consider MEV risks in aggregation
- Sanitize data from multiple DEX sources
Integration with MEV Bot
- Compare aggregator routes with direct swaps
- Include gas costs in profitability calculations
- Monitor aggregator-specific MEV opportunities
- Track split trades as potential MEV targets
- Consider front-running protection for aggregated trades
- Optimize for different trade sizes and market conditions
