🛠️ Development

make install   # Install dependencies
make lint      # Run linting
make format    # Format code
make test      # Run tests
make cov       # Run tests with coverage
make build     # Build Docker image
make run       # Run Docker container
make kill      # Stop container gracefully
make deploy    # Deploy to AWS

⚡ MEV Relays

The node connects to multiple MEV relays for optimal block building:

Mainnet: Flashbots, Ultra Sound, bloXroute, Aestus, Agnostic, Titan, Wenmerge

Hoodi: Flashbots, Aestus, bloXroute, Titan

Relays are automatically tested on startup; unreliable ones are filtered out.

💾 Backup Strategy

• Snapshots created every 30 days
• Maximum 3 snapshots retained (90 days)
• Automatic launch template updates with latest snapshot
• Graceful shutdown triggers snapshot on instance draining
