# Running a Reth Node

This is a unified implementation of the Reth node setup that supports running both OP Reth and Base Reth with Flashblocks support.

## Setup

- See hardware requirements mentioned in the master README
- For Base Reth mode: Access to a Flashblocks websocket endpoint (for `RETH_FB_WEBSOCKET_URL`)
  - We provide public websocket endpoints for mainnet and devnet, included in `.env.mainnet` and `.env.sepolia`

## Node Type Selection

Use the `NODE_TYPE` environment variable to select the implementation:

- `NODE_TYPE=vanilla` - OP Reth implementation (default)
- `NODE_TYPE=base` - Base L2 Reth implementation with Flashblocks support

## Running the Node

The node follows the standard `docker-compose` workflow in the master README.

```bash
# Run OP Reth node
CLIENT=reth docker-compose up

# Run Base L2 Reth node with Flashblocks support
NODE_TYPE=base CLIENT=reth docker-compose up
```

## Testing Flashblocks RPC Methods

When running in Base mode (`NODE_TYPE=base`), you can query a pending block using the Flashblocks RPC:

```bash
curl -X POST \
  --data '{"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["pending", false],"id":1}' \
  http://localhost:8545
```
