```
|
|
|
|
## Configuration
|
|
|
|
The CLI tool uses environment variables and command-line flags for configuration:
|
|
|
|
### Required Environment Variables
|
|
|
|
```bash
|
|
export ARBITRUM_RPC_ENDPOINT="https://arb1.arbitrum.io/rpc"
|
|
export PRIVATE_KEY="your-private-key-hex" # Optional for dry-run mode
|
|
```
|
|
|
|
### Optional Environment Variables
|
|
|
|
```bash
|
|
export WALLET_ADDRESS="0x..." # If not using private key
|
|
export LOG_LEVEL="info" # debug, info, warn, error
|
|
```
|
|
|
|

|
|
|
|
## Security Considerations
|
|
|
|
1. **Private Key Management**: Never commit private keys to version control
|
|
2. **Dry-Run First**: Always test with `--dry-run` before executing
|
|
3. **Slippage Settings**: Be careful with slippage on volatile tokens
|
|
4. **Gas Price**: Monitor network conditions for optimal gas pricing
|
|
5. **Token Verification**: Always verify token contract addresses
|
|
|
|
## Error Handling
|
|
|
|
The CLI provides detailed error messages for common issues:
|
|
|
|
- Insufficient balance
|
|
- Invalid token addresses
|
|
- Network connectivity issues
|
|
- Gas estimation failures
|
|
- Transaction reverts
|
|
|
|
## Development
|
|
|
|
### Adding New Protocols
|
|
|
|
1. Add the protocol to the router address mapping in `getRouterAddress()`
|
|
2. Implement the protocol-specific swap function
|
|
3. Add any protocol-specific parameters to the CLI flags
|
|
4. Update this README with usage examples
|
|
|
|
### Testing
|
|
|
|
```bash
|
|
# Test with dry-run mode
|
|
./swap-cli --dry-run uniswap-v3 --token-in ... --token-out ... --amount-in ...
|
|
|
|
# Test gas estimation
|
|
./swap-cli estimate-gas --token-in ... --token-out ... --amount-in ...
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
### Common Issues
|
|
|
|
1. **"Insufficient balance"**: Check token balance and decimals
|
|
2. **"Transaction reverted"**: Check allowances and slippage settings
|
|
3. **"Gas estimation failed"**: Try setting manual gas limits
|
|
4. **"Invalid private key"**: Ensure key is in hex format without 0x prefix
|
|
|
|
### Debug Mode
|
|
|
|
Enable debug logging for detailed information:
|
|
|
|
```bash
|
|
./swap-cli --log-level debug ...
|
|
```
|
|
|
|
## Contributing
|
|
|
|
1. Follow the existing code structure
|
|
2. Add comprehensive error handling
|
|
3. Include dry-run simulation support
|
|
4. Update documentation for new features
