# Curve Integration Plan
|
|
|
|
## Overview
|
|
|
|
This document outlines the implementation plan for Curve exchange support in the MEV bot. Curve specializes in stablecoin and pegged-asset swaps with low slippage and low fees.
|
|
|
|
## Contract Architecture
|
|
|
|
### Core Contracts
|
|
- Main Registry: `0x7D86446dDb609eD0F5f8684AcF3037Ffb6149cC6`
|
|
- Factory Registry: `0xF1815bdCbcC67D79Cbb7B3C7b2E6d9992E6C1e86`
|
|
- Router: `0x8474DdbE98F5aC77e0C38b3C97ad441436D69d2C`
|
|
- Exchange Proxy: `0xD152CC3E6A9Ca3Cd5085767eD16a8921152B6867`
|
|
|
|
### Pool Types
|
|
- StableSwap pools (3pool, 4pool, etc.)
|
|
- CryptoSwap pools (tricrypto, etc.)
|
|
- MetaStable pools
|
|
- Lending pools
|
|
- Factory pools
|
|
|
|
## Core Functions
|
|
|
|
### Swap Functions
|
|
- `exchange` (basic swap)
|
|
- `exchange_underlying` (swap underlying assets)
|
|
- `get_dy` (calculate output without executing)
|
|
- `get_dx` (calculate input without executing)
|
|
- `exchange_extra` (swap with additional features)
|
|
|
|
### Pool Management
|
|
- `add_liquidity`
|
|
- `remove_liquidity`
|
|
- `remove_liquidity_one_coin`
|
|
- `calc_token_amount` (estimate LP token amount)
|
|
- `calc_withdraw_one_coin` (estimate withdrawal amount)
|
|
|
|
### Pool-Specific Functions
|
|
- Pool-specific swap functions for different curve types
|
|
- Virtual price calculations
|
|
- Fee distribution functions
|
|
- Pool parameter modifications
|
|
|
|
## Implementation Steps
|
|
|
|
1. Create Curve struct implementing the Exchange interface
|
|
2. Implement adapter for different pool types
|
|
3. Handle curve's unique pricing mechanism (constant function AMM optimized for similar assets)
|
|
4. Implement multi-hop swaps between different pool types
|
|
5. Add support for underlying asset swaps
|
|
6. Implement virtual price calculations
|
|
7. Add support for factory-deployed pools
|
|
8. Create pool discovery and indexing functions
|
|
|
|
## Pricing Mechanisms
|
|
|
|
### Curve-Specific Pricing
|
|
- Use Curve's mathematical formula for stablecoin swaps
|
|
- Account for amplification coefficient (A)
|
|
- Consider fee structure (dynamic based on trade size)
|
|
- Handle different pool types with varying parameters
|
|
- Calculate virtual price for accurate pricing
|
|
|
|
### Multi-Asset Pools
|
|
- Support for pools with 2, 3, 4+ assets
|
|
- Handle asymmetric deposits/withdrawals
|
|
- Calculate effective rates between different asset pairs
|
|
|
|
## Testing Plan
|
|
|
|
1. Unit tests for stablecoin swap functions
|
|
2. Testing with different amplification coefficients
|
|
3. Virtual price calculation verification
|
|
4. Multi-asset pool testing
|
|
5. Factory pool integration tests
|
|
6. Edge case testing (extreme amounts, pool imbalance)
|
|
7. Price accuracy verification across different pool types
|
|
8. Gas optimization testing
|
|
|
|
## Performance Considerations
|
|
|
|
- Optimize for low slippage stablecoin swaps
|
|
- Cache pool parameters to reduce external calls
|
|
- Implement efficient multi-hop routing
|
|
- Consider pool liquidity depth for trade execution
|
|
- Batch operations where possible
|
|
|
|
## Security Considerations
|
|
|
|
- Validate curve pool addresses and parameters
|
|
- Implement proper slippage protection despite low slippage
|
|
- Handle emergency pause functions
|
|
- Verify gauge contracts for liquidity mining
|
|
- Sanitize data from external curve contracts
|
|
|
|
## Integration with MEV Bot
|
|
|
|
- Identify curve-specific arbitrage opportunities
|
|
- Monitor stablecoin pools for profitable swaps
|
|
- Track meta-stable pools for cross-chain opportunities
|
|
- Include lending pools in yield farming strategies
|
|
- Coordinate with other exchanges for maximum profit |
