# Robinhood RPC quickstart

> Connect to Robinhood Chain mainnet and testnet with Conduit RPC Nodes.

## About Robinhood Chain

[Robinhood Chain](https://docs.robinhood.com/chain/) is an Ethereum layer 2 network built with Arbitrum technology. You can use Ethereum tools to build apps and test them on Robinhood Chain testnet. Both networks use ETH for transaction fees.

## Robinhood JSON-RPC API

The Robinhood JSON-RPC API lets you read chain data and submit signed transactions through remote procedure calls (RPC) using standard Ethereum JSON-RPC methods. Conduit runs the nodes, so you can connect to Robinhood Chain without running your own infrastructure. Your RPC URL includes an API key for authenticated access.

## Network details

| Network                 | Type    | Chain ID | HTTP RPC URL                                           | WebSocket RPC URL                                    |
| ----------------------- | ------- | -------- | ------------------------------------------------------ | ---------------------------------------------------- |
| Robinhood Chain         | mainnet | 4663     | `https://robinhood-mainnet.n.conduit.xyz/YOUR_API_KEY` | `wss://robinhood-mainnet.n.conduit.xyz/YOUR_API_KEY` |
| Robinhood Chain testnet | testnet | 46630    | `https://robinhood-testnet.n.conduit.xyz/YOUR_API_KEY` | `wss://robinhood-testnet.n.conduit.xyz/YOUR_API_KEY` |

The [Robinhood network reference](https://docs.robinhood.com/chain/connecting/) lists block explorers and other network details.

## Get a Robinhood endpoint

#### Create a Conduit account

Sign in to the [Conduit App](https://app.conduit.xyz) with your work email.

#### Create an API key

Open [Nodes](https://app.conduit.xyz/nodes) and select **Create API key**. Follow the [API key guide](/rpc-nodes/getting-started/get-api-key) to configure access controls.

#### Copy your Robinhood RPC URL

In the **Endpoints** tab, find Robinhood mainnet or testnet and copy the RPC URL with your API key appended.

## Check your connection

Set `RPC_URL` to your Robinhood Chain testnet URL, then request the chain ID. This read doesn't require a funded wallet.

```bash
export RPC_URL='https://robinhood-testnet.n.conduit.xyz/YOUR_API_KEY'
curl "$RPC_URL" \
  --header 'Content-Type: application/json' \
  --data '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}'
```

The expected result is:

```json
{"jsonrpc":"2.0","id":1,"result":"0xb626"}
```

For Robinhood Chain mainnet, use the mainnet URL and expect `0x1237`. If the chain ID differs, check your selected network before sending transactions. Keep API keys out of source control and shared logs.
