Robinhood RPC quickstart
About Robinhood Chain
Robinhood 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
The Robinhood network reference lists block explorers and other network details.
Get a Robinhood endpoint
Create an API key
Open Nodes and select Create API key. Follow the API key guide to configure access controls.
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.
The expected result is:
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.
