- Implement proper transaction waiting and confirmation handling.
- Use TypedDataEncoder for EIP-712 structured data.
- Implement proper ABI handling and contract interfaces.
- Use proper BigNumber operations for precise calculations.
- Handle events and logs efficiently.
- Implement proper ENS resolution when needed.
- Use proper network management and chain ID validation.
## Hyperliquid Integration
- Implement proper market data handling and order book management.
- Use correct position management and margin calculations.
- Implement proper perpetual contract interactions.
- Handle oracle price feeds correctly.
- Use proper order types and execution parameters.
- Implement proper fee calculations and management.
- Handle proper liquidation prevention measures.
- Use proper risk management techniques.
## Security
- Implement proper private key and signature management.
- Use secure RPC endpoints and provider configuration.
- Implement proper nonce management.
- Handle transaction reversion properly.

- Implement proper caching strategies.
- Use efficient event filtering and subscription patterns.
- Optimize contract calls and state reads.
- Implement proper websocket connection management.
- Use proper memory management for large datasets.
## Testing
- Implement comprehensive unit tests for contract interactions.
- Test different network conditions and error states.
- Validate transaction formatting and signing.
- Test different order types and execution scenarios.
- Implement proper integration tests.
- Test different market conditions and edge cases.
## Error Handling
- Implement proper try-catch blocks for async operations.
- Handle network errors and timeouts properly.
- Implement proper fallback mechanisms.
- Handle proper transaction replacement strategies.
- Implement robust error reporting and logging.
## Documentation
- Document all function parameters and return types clearly.
