# Development Environment Setup
## Overview
This project enforces **containerized development** for consistency and adherence to SPEC.md requirements.
## Key Documents
- **SPEC.md** - Technical specification and architecture requirements
- **CLAUDE.md** - Development guidelines and workflow
- **bindings/README.md** - Contract bindings usage and generation
## Quick Start
```bash
# 1. Start development containers
./scripts/dev.sh up
# 2. Build contracts
./scripts/dev.sh forge-build
# 3. Generate Go bindings
./scripts/dev.sh bindings
# 4. Build Go application
./scripts/dev.sh build
# 5. Run tests
./scripts/dev.sh test
```
## Development Workflow
### 1. Container-Based Development
**NEVER run builds or tests outside of containers.**
All commands use `./scripts/dev.sh` which ensures:
- Consistent build environment
- Proper dependency management
- Compliance with SPEC.md
- Reproducible builds
### 2. Contract Development
```bash
# Build all Solidity contracts
./scripts/dev.sh forge-build
# Run contract tests
./scripts/dev.sh forge-test
# Generate Go bindings from ABIs
./scripts/dev.sh bindings
```
**Contract Structure:**
```
contracts/
├── lib/ # Foundry dependencies (official DEX contracts)
│ ├── v2-core/ # Uniswap V2
│ ├── v3-core/ # Uniswap V3
│ ├── v3-periphery/ # Uniswap V3 Router
│ └── openzeppelin/ # OpenZeppelin contracts
├── src/ # Custom contracts and interfaces
│ ├── interfaces/ # Interface definitions
│ ├── libraries/ # Utility libraries
│ └── utils/ # Helper contracts
├── out/ # Build artifacts (ABIs, bytecode)
└── foundry.toml # Foundry configuration
```
### 3. Go Development
```bash
# Build application
./scripts/dev.sh build
# Run tests
./scripts/dev.sh test
# Enter Go container for interactive development
./scripts/dev.sh go
# Inside container:
# go test ./pkg/sequencer/... -v
# go run ./cmd/mev-bot/main.go
```
### 4. Binding Generation
**IMPORTANT**: Use official contract ABIs from Foundry builds, NOT manual JSON files.
```bash
# 1. Build contracts first
./scripts/dev.sh forge-build
# 2. Generate bindings
./scripts/dev.sh bindings
# Generated bindings appear in:
bindings/
├── uniswap_v2/
│ ├── router.go # UniswapV2Router02
│ └── pair.go # UniswapV2Pair
├── uniswap_v3/
│ ├── router.go # SwapRouter
│ └── pool.go # UniswapV3Pool
└── README.md # Usage documentation
```

## Container Reference
### mev-go-dev
- **Image**: `golang:1.21-alpine`
- **Purpose**: Go development, testing, building
- **Tools**: go, abigen, gcc, git
- **Working Dir**: `/workspace`
- **Access**: `./scripts/dev.sh go`
### mev-foundry
- **Image**: `ghcr.io/foundry-rs/foundry:latest`
- **Purpose**: Solidity contract development
- **Tools**: forge, cast, anvil
- **Working Dir**: `/workspace`
- **Access**: `./scripts/dev.sh foundry`
### mev-python-dev
- **Image**: `python:3.11-slim`
- **Purpose**: Analysis scripts, data processing
- **Tools**: python, pip
- **Working Dir**: `/workspace`
- **Access**: `./scripts/dev.sh python`
## Common Tasks
### Adding New DEX Contract
```bash
# 1. Enter Foundry container
./scripts/dev.sh foundry
# 2. Install official contract
cd /workspace/contracts
forge install <org>/<repo>
# 3. Exit container and rebuild
exit
./scripts/dev.sh forge-build
# 4. Generate Go bindings
./scripts/dev.sh bindings
```
### Debugging Build Issues
```bash
# Check container status
./scripts/dev.sh ps
# View logs
./scripts/dev.sh logs go-dev
# Clean and rebuild
./scripts/dev.sh clean
./scripts/dev.sh forge-build
./scripts/dev.sh build
```
### Running Specific Tests
```bash
# Enter Go container
./scripts/dev.sh go
# Inside container, run specific tests
go test ./pkg/sequencer/... -v -run TestSwapFilter
go test ./pkg/pools/... -v -run TestPoolCache
```
## Development Rules (from SPEC.md)
### MUST DO ✅
- Use `./scripts/dev.sh` for all operations
- Use Arbitrum sequencer feed as primary data source
- Derive contract ABIs from official sources via Foundry
- Generate Go bindings with `abigen`
- Use channels for ALL inter-component communication
- Validate ALL parsed data before propagation
- Emit comprehensive metrics and structured logs
### MUST NOT DO ❌
- Run builds outside of containers
- Use HTTP RPC as primary data source
- Write manual ABI JSON files
- Hardcode function selectors
- Allow zero addresses or zero amounts to propagate
- Use blocking operations in hot paths
## Troubleshooting
### Container Won't Start
```bash
# Check Podman status
podman ps -a
# Check logs
podman logs mev-go-dev
# Force restart
./scripts/dev.sh down
./scripts/dev.sh up
```
### Build Failures
```bash
# Clean artifacts
./scripts/dev.sh clean
# Restart containers
./scripts/dev.sh restart
# Rebuild
./scripts/dev.sh forge-build
./scripts/dev.sh build
```
### Binding Generation Fails
```bash
# Ensure contracts are built first
./scripts/dev.sh forge-build
# Check for artifacts
ls -la contracts/out/
# Manually generate if needed
./scripts/dev.sh go
# Inside container:
./scripts/generate-bindings-in-container.sh
```
## Next Steps
1. **Add More DEX Contracts**: Install Camelot, Balancer, Curve, Kyber
2. **Fix Contract Compilation**: Resolve Solidity errors in src/
3. **Complete Swap Detection**: Implement ABI-based swap parsing
4. **Test Pool Discovery**: Verify pool cache functionality
5. **Deploy Phase 1**: Monitor sequencer feed in production
