Krypto Kajun 850223a953 fix(multicall): resolve critical multicall parsing corruption issues

- Added comprehensive bounds checking to prevent buffer overruns in multicall parsing
- Implemented graduated validation system (Strict/Moderate/Permissive) to reduce false positives
- Added LRU caching system for address validation with 10-minute TTL
- Enhanced ABI decoder with missing Universal Router and Arbitrum-specific DEX signatures
- Fixed duplicate function declarations and import conflicts across multiple files
- Added error recovery mechanisms with multiple fallback strategies
- Updated tests to handle new validation behavior for suspicious addresses
- Fixed parser test expectations for improved validation system
- Applied gofmt formatting fixes to ensure code style compliance
- Fixed mutex copying issues in monitoring package by introducing MetricsSnapshot
- Resolved critical security vulnerabilities in heuristic address extraction
- Progress: Updated TODO audit from 10% to 35% complete

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

Create SushiSwap struct implementing the Exchange interface
Configure multiple network support
Implement standard Uniswap V2 compatible functions
Add Sushi-specific reward tracking
Implement SushiBar staking functions
Add MasterChef integration for liquidity mining
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

Unit tests for all swap functions
Cross-network functionality verification
Sushi reward tracking validation
Liquidity mining calculations
Integration tests with mainnet fork
Edge case testing (zero amounts, max amounts)
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
