## CLI Options

The Base Reth Node inherits Reth's comprehensive CLI. View all options:

```bash
./target/release/base-reth-node --help
```

Key option categories:

- **Network** — Chain selection, bootnodes, P2P port
- **RPC** — HTTP/WS endpoints, CORS, API namespaces
- **Database** — Data directory, state pruning
- **Metrics** — Prometheus endpoint
- **Engine API** — JWT secret, engine API endpoint
- **Logging** — Log level, log format

## Environment Variables

Configuration can also be set via environment variables. The devnet uses `etc/docker/devnet-env` for its environment.

## Build Profiles

The workspace defines several Cargo build profiles:

| Profile | Use Case | Key Settings |
|---------|---------|-------------|
| `dev` | Development | `debug = "line-tables-only"`, `incremental = false` |
| `release` | Production | `opt-level = 3`, `lto = "thin"`, `strip = "symbols"` |
| `maxperf` | Maximum performance | `lto = "fat"`, `codegen-units = 1` |
| `profiling` | Performance analysis | `debug = "line-tables-only"`, `frame-pointers = true` |
| `ci` | CI builds | `debug = false`, minimal disk usage |

## basectl

The [`basectl`](/node-operations/basectl/) utility provides configuration management for different network targets:

```bash
# Mainnet configuration
cargo run -p basectl --release -- -c mainnet

# Sepolia testnet
cargo run -p basectl --release -- -c sepolia

# Local devnet
cargo run -p basectl --release -- -c devnet
```
