# Uniswap V4 Integration Plan
|
|
|
|
## Overview
|
|
|
|
This document outlines the implementation plan for Uniswap V4 exchange support in the MEV bot. Uniswap V4 introduces hooks and a new architecture with the PoolManager contract that allows for more flexible and customizable pool behavior.
|
|
|
|
## Contract Architecture
|
|
|
|
### Core Contracts
|
|
|
|
- PoolManager: `0x000000000022D473030F116dDEE9F6B7653f39281251` (placeholder)
|
|
- PositionManager: `0x000000000022D473030F116dDEE9F6B7653f39281252` (placeholder)
|
|
|
|
### Key Features
|
|
- Hooks: Custom contracts that can run before/after swaps and liquidity operations
|
|
- Concentrated Liquidity: Similar to V3 but with more flexibility
|
|
- Flexible Fees: Dynamic fee structures
|
|
- Position Management: More efficient position management
|
|
|
|
## Core Functions
|
|
|
|
### Swap Functions
|
|
- `exactInputSingle`
|
|
- `exactOutputSingle`
|
|
- `exactInput`
|
|
- `exactOutput`
|
|
|
|
### Liquidity Functions
|
|
- `mint` (add liquidity to a range)
|
|
- `burn` (remove liquidity from a range)
|
|
- `increaseLiquidity`
|
|
- `decreaseLiquidity`
|
|
- `collect` (collect fees and tokens)
|
|
|
|
### Pool Management
|
|
- `getPool` (get pool address by tokens and hooks)
|
|
- `getLiquidity` (get liquidity at a tick)
|
|
- `getPosition` (get liquidity position details)
|
|
|
|
## Implementation Steps
|
|
|
|
1. Create UniswapV4 struct implementing the Exchange interface
|
|
2. Initialize connection to Uniswap V4 PoolManager
|
|
3. Handle hook-based pool creation and management
|
|
4. Implement swap functions with hook integration
|
|
5. Implement liquidity functions with hook support
|
|
6. Implement pricing functions using concentrated liquidity
|
|
7. Add support for hook-specific parameters
|
|
8. Implement gas estimation for hook operations
|
|
9. Add error handling for hook failures
|
|
|
|
## Pricing Mechanisms
|
|
|
|
### Concentrated Liquidity Pricing
|
|
- Calculate price based on current tick and liquidity
|
|
- Consider tick range and liquidity distribution
|
|
- Implement dynamic fee calculations based on pool configuration
|
|
- Account for hook-specific pricing adjustments
|
|
|
|
### Hook Integration
|
|
- Support for pre-swap hooks
|
|
- Support for post-swap hooks
|
|
- Custom fee calculations based on hooks
|
|
- Position management with hooks
|
|
|
|
## Testing Plan
|
|
|
|
1. Unit tests for all swap functions
|
|
2. Integration tests with mainnet fork
|
|
3. Hook-specific functionality tests
|
|
4. Edge case testing (zero amounts, max amounts)
|
|
5. Gas optimization verification
|
|
6. Slippage tolerance testing
|
|
7. Price accuracy verification
|
|
8. Hook failure scenario testing
|
|
|
|
## Performance Considerations
|
|
|
|
- Efficient hook execution to minimize gas costs
|
|
- Batch operations where possible to reduce gas costs
|
|
- Cache pool and hook information to reduce external calls
|
|
- Optimize route selection for multi-hop swaps
|
|
- Implement efficient price impact calculations
|
|
- Consider hook-specific optimization strategies
|
|
|
|
## Security Considerations
|
|
|
|
- Validate all input parameters
|
|
- Implement proper slippage protection
|
|
- Verify hook contracts are legitimate
|
|
- Prevent malicious hook execution
|
|
- Check for reentrancy vulnerabilities in hook contracts
|
|
- Sanitize all external data from hooks
|
|
|
|
## Integration with MEV Bot
|
|
|
|
- Identify Uniswap V4-specific arbitrage opportunities
|
|
- Monitor hook-enabled pools for unique opportunities
|
|
- Account for hook-specific execution costs
|
|
- Coordinate with other exchanges for cross-exchange arbitrage
|
|
- Consider hook-based MEV protection or opportunities
|
|
- Optimize for V4's more flexible liquidity management |
