Kyber Integration Plan
Overview
This document outlines the implementation plan for Kyber exchange support in the MEV bot, specifically focusing on Kyber Elastic (V3+) which uses concentrated liquidity similar to Uniswap V3 but with additional flexibility.
Contract Architecture
Core Contracts
- Router:
0x613a63565357403C0A62b93c3e5E2a19863c6720(placeholder) - Pool Factory:
0x5a2206a46A0C1958E3D7478959E6F9777A4A2b76(placeholder) - Pool Manager: Manages liquidity positions
Pool Types
- Elastic Pools (concentrated liquidity)
- Different fee tiers (400, 1000, 2000, 4000 bps)
- Configurable parameters per pool
Core Functions
Swap Functions
swap(single token swap)multiswap(multi-hop swap)swapWithPermit(swap with permit signature)
Liquidity Functions
mint(add liquidity to a range)burn(remove liquidity from a range)collect(collect fees)flash(flash loans)
Pool Management
getPool(get pool address by tokens and fee tier)getLiquidity(get liquidity at a tick)getPosition(get liquidity position details)
Implementation Steps
- Create Kyber struct implementing the Exchange interface
- Initialize connection to Kyber contracts
- Implement concentrated liquidity operations
- Implement swap functions with tick math
- Implement pricing functions using tick-based pricing
- Add support for different fee tiers
- Implement gas estimation for swap and liquidity operations
- Add error handling for common failure cases
Pricing Mechanisms
Tick-based Pricing
- Calculate price based on current tick and liquidity
- Consider tick range and liquidity distribution
- Implement dynamic fee calculations based on pool configuration
Fee Calculation
- Kyber uses different fee structures per pool
- Fees may vary based on volatility and utilization
- Fee growth tracking for position management
Testing Plan
- Unit tests for all swap functions
- Integration tests with mainnet fork
- Edge case testing (zero amounts, max amounts)
- Gas optimization verification
- Slippage tolerance testing
- Price accuracy verification
- Concentrated liquidity position tests
Performance Considerations
- Efficient tick math implementations
- Batch operations where possible to reduce gas costs
- Cache pool information to reduce external calls
- Optimize route selection for multi-hop swaps
- Implement efficient price impact calculations
Security Considerations
- Validate all input parameters
- Implement proper slippage protection
- Prevent sandwich attacks where possible
- Sanitize all external data
- Verify hook contracts (if applicable)
- Check for reentrancy vulnerabilities
Integration with MEV Bot
- Identify Kyber-specific arbitrage opportunities
- Monitor concentrated liquidity pools for profitable swaps
- Include position management in liquidity strategies
- Coordinate with other exchanges for cross-exchange arbitrage
- Account for Kyber's fee structures in profitability calculations
