# SushiSwap Integration Plan
|
|
|
|
## Overview
|
|
|
|
This document outlines the implementation plan for SushiSwap exchange support in the MEV bot. SushiSwap is largely compatible with Uniswap V2 but has its own contracts and features.
|
|
|
|
## Contract Addresses
|
|
|
|
### Ethereum Mainnet
|
|
- Router: `0xd9e1cE17f2641f24aE83637ab66a2cca9C378B9F`
|
|
- Factory: `0xC0AEe478e3658e2610c5F7A4A2E1777cE9e4f2Ac`
|
|
|
|
### Other Networks
|
|
- Polygon: Router `0x1b02dA8Cb0d097eB8D57A175b88c7D8b47997506`
|
|
- Arbitrum: Router `0x1b02dA8Cb0d097eB8D57A175b88c7D8b47997506`
|
|
- Avalanche: Router `0x1b02dA8Cb0d097eB8D57A175b88c7D8b47997506`
|
|
|
|
## Core Functions
|
|
|
|
### Swap Functions
|
|
- `swapExactTokensForTokens`
|
|
- `swapTokensForExactTokens`
|
|
- `swapExactETHForTokens`
|
|
- `swapTokensForExactETH`
|
|
- `getAmountsOut`
|
|
- `getAmountsIn`
|
|
|
|
### Liquidity Functions
|
|
- `addLiquidity`
|
|
- `addLiquidityETH`
|
|
- `removeLiquidity`
|
|
- `removeLiquidityETH`
|
|
|
|
### Sushi-specific Features
|
|
- Onsen (yield farming) integration
|
|
- Kashi (lending) integration
|
|
- SushiBar (staking) integration
|
|
- MasterChef (liquidity mining) integration
|
|
- BentoBox (yield aggregator)
|
|
- Kashi V3 (next-gen lending)
|
|
|
|
## Implementation Steps
|
|
|
|
1. Create SushiSwap struct implementing the Exchange interface
|
|
2. Configure multiple network support
|
|
3. Implement standard Uniswap V2 compatible functions
|
|
4. Add Sushi-specific reward tracking
|
|
5. Implement SushiBar staking functions
|
|
6. Add MasterChef integration for liquidity mining
|
|
7. Implement cross-chain liquidity tracking
|
|
|
|
## Pricing Mechanisms
|
|
|
|
### Standard AMM Pricing
|
|
- Use reserves to calculate price impact
|
|
- Apply standard constant product formula: x * y = k
|
|
- Consider 0.3% swap fee in calculations
|
|
|
|
### Special Considerations
|
|
- Handle Sushi reward calculations
|
|
- Consider MasterChef incentive effects on liquidity
|
|
- Track special pools with additional rewards
|
|
|
|
## Testing Plan
|
|
|
|
1. Unit tests for all swap functions
|
|
2. Cross-network functionality verification
|
|
3. Sushi reward tracking validation
|
|
4. Liquidity mining calculations
|
|
5. Integration tests with mainnet fork
|
|
6. Edge case testing (zero amounts, max amounts)
|
|
7. Price accuracy verification
|
|
|
|
## Performance Considerations
|
|
|
|
- Leverage existing Uniswap V2 knowledge for faster implementation
|
|
- Optimize for multi-chain deployment
|
|
- Cache frequently accessed pool information
|
|
- Batch operations to reduce transaction costs
|
|
- Consider SushiBar staking as liquidity source
|
|
|
|
## Security Considerations
|
|
|
|
- Validate all input parameters
|
|
- Implement proper slippage protection
|
|
- Sanitize data from external contracts
|
|
- Verify contract addresses on different chains
|
|
- Handle chain-specific security requirements
|
|
|
|
## Integration with MEV Bot
|
|
|
|
- Identify SushiSwap-specific arbitrage opportunities
|
|
- Monitor Onsen pools for profitable swaps
|
|
- Track Sushi rewards in opportunity evaluation
|
|
- Include MasterChef incentives in profitability calculations
|
|
- Coordinate with other exchanges for cross-exchange arbitrage |
