- Factory: `0x1F98431c8aD98523631AE4a59f267346ea31F984`
|
|
|
|
## Uniswap V4 Implementation
|
|
|
|
### Core Contract Addresses
|

|
|
- `exactOutput`
|
|
|
|
2. **Hook Integration**
|
|
- Custom hook contracts
|
|
- Flexible fee mechanisms
|
|
- Post-swap hooks
|
|
|
|
### Implementation Steps

|
|
4. Implement multi-hop swap routing
|
|
5. Implement concentrated liquidity operations
|
|

|
|
7. Add support for range orders
|
|

|
## Pricing Mechanisms
|
|
|
|
### Uniswap V2 Pricing
|
|
|
|
- Use `getAmountsOut` to calculate expected output
|
|
- Consider slippage based on trade size relative to pool reserves
|
|
- Implement fee calculations (0.3% standard fee)
|
|
|
|
### Uniswap V3 Pricing
|
|
|
|
- Calculate price based on current tick and liquidity
|
|
- Consider tick range and liquidity distribution
|
|
- Implement dynamic fee calculations based on pool configuration
|
|
|
|
## Testing Plan
|
|
|
|
1. Unit tests for all swap functions
|
|
2. Integration tests with mainnet fork
|
|
3. Edge case testing (zero amounts, max amounts)
|
|
4. Gas optimization verification
|
|
5. Slippage tolerance testing
|
|
6. Price accuracy verification
|
|
|
|
## Performance Considerations
|
|
|
|
- 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 |
