fix: resolve all compilation issues across transport and lifecycle packages
- Fixed duplicate type declarations in transport package - Removed unused variables in lifecycle and dependency injection - Fixed big.Int arithmetic operations in uniswap contracts - Added missing methods to MetricsCollector (IncrementCounter, RecordLatency, etc.) - Fixed jitter calculation in TCP transport retry logic - Updated ComponentHealth field access to use transport type - Ensured all core packages build successfully All major compilation errors resolved: ✅ Transport package builds clean ✅ Lifecycle package builds clean ✅ Main MEV bot application builds clean ✅ Fixed method signature mismatches ✅ Resolved type conflicts and duplications 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

# Swap CLI Tool
|
||||
|
||||
A standalone command-line interface for executing swaps on Arbitrum using various DEX protocols.
|
||||
|
||||
## Features
|
||||
|
||||
- Support for multiple DEX protocols:
|
||||
- Uniswap V2 & V3
|
||||
- SushiSwap
|
||||
- Camelot V3
|
||||
- TraderJoe V2
|
||||
- KyberSwap Elastic
|
||||
- Dry-run simulation mode
|
||||
- Gas estimation
|
||||
- Token allowance management
|
||||
- Configurable slippage and deadlines
|
||||
- Comprehensive logging
|
||||
|
||||
## Installation
|
||||
|
||||
```bash
|
||||
# Build the CLI tool
|
||||
cd cmd/swap-cli
|
||||
go build -o swap-cli .
|
||||
|
||||
# Or build from project root
|
||||
make build-swap-cli
|
||||
```
|
||||
|
||||
## 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
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Basic Swap Commands
|
||||
|
||||
```bash
|
||||
# Dry-run swap simulation (no actual transaction)
|
||||
./swap-cli --dry-run uniswap-v3 \
|
||||
--token-in 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 \
|
||||
--token-out 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
|
||||
--amount-in 1000000000 \
|
||||
--slippage 0.5
|
||||
|
||||
# Execute actual swap on Uniswap V3
|
||||
./swap-cli uniswap-v3 \
|
||||
--token-in 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 \

--amount-in 1000000000 \
|
||||
--slippage 0.5 \
|

|
||||
### Gas Estimation
|
||||
|
||||
```bash
|

--amount-in 1000000000
|
||||
```
|
||||
|
||||
### Token Management
|
||||
|
||||
```bash
|
||||
# Check token allowance
|
||||
./swap-cli check-allowance \
|
||||
--token 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 \

```bash
|
||||
# USDC
|
||||
USDC="0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"
|
||||
|
||||
# WETH
|
||||
WETH="0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2"
|
||||
|
||||
# ARB
|
||||
ARB="0x912CE59144191C1204E64559FE8253a0e49E6548"
|
||||
|
||||
# USDT
|
||||
USDT="0xdAC17F958D2ee523a2206206994597C13D831ec7"
|
||||
```
|
||||
|
||||
### Example Swaps
|
||||
|
||||
```bash
|
||||
# Swap 100 USDC for WETH on Uniswap V3
|
||||
./swap-cli uniswap-v3 \
|
||||
--token-in 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 \
|
||||
--token-out 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
|
||||
--amount-in 100000000 \
|
||||
--slippage 0.5
|
||||
|
||||
# Swap 1 WETH for USDC on SushiSwap
|
||||
./swap-cli sushiswap \
|
||||
--token-in 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
|
||||
--token-out 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 \
|
||||
--amount-in 1000000000000000000 \
|
||||
--slippage 1.0
|
||||
|
||||
# High-precision swap with custom gas settings
|
||||
./swap-cli uniswap-v3 \
|
||||
--token-in 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 \
|
||||
--token-out 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
|
||||
--amount-in 1000000000 \
|
||||
--min-amount-out 995000000000000000 \
|
||||
--slippage 0.1 \
|
||||
--gas-price 0.1 \
|
||||
--gas-limit 200000 \
|
||||
--deadline 600
|
||||
```
|
||||
|
||||
## 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
