Free Robinhood Chain RPC Endpoint

Free Robinhood Chain RPC endpoint — Chain ID 4663 (0x1237), no API key needed. Add to MetaMask in seconds. Works with Klik, DeFi, and RWA apps on Robinhood's Arbitrum Orbit L2.

Robinhood Chain is Robinhood's Arbitrum Orbit L2, built for tokenized real-world assets, with blocks as fast as ~250 ms. It's brand-new — and almost no independent RPC providers serve it yet. NodeFlare runs a dedicated Robinhood Chain node, giving you an alternative to the single official endpoint.

Robinhood Chain RPC URLs

Public endpoint — no API key:

https://rpc.nodeflare.app/robinhood/public

Keyed endpoint (free account — higher limits, heavy methods):

https://rpc.nodeflare.app/robinhood/v1/{YOUR_KEY}

Quick start

Terminal
curl https://rpc.nodeflare.app/robinhood/public \
  -X POST \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'

Expected: {"jsonrpc":"2.0","id":1,"result":"0x1237"} — that's 4663, Robinhood Chain mainnet.

JavaScript
import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider(
  'https://rpc.nodeflare.app/robinhood/public'
);
console.log('Robinhood Chain block:', await provider.getBlockNumber());

As an Orbit chain, blocks are produced on demand: they can be ~250 ms apart under load, with longer gaps in quiet periods. eth_estimateGas includes the L1 data component, so estimates look higher than pure execution — that's expected Nitro behaviour. Chain-specific notes for every method live in the per-method reference.

Using Robinhood Chain with Klik and DeFi apps

Klik and other DeFi apps on Robinhood Chain require a working RPC endpoint to interact with the network. The NodeFlare public endpoint works directly in MetaMask or any EVM-compatible wallet — paste the URL and Chain ID 4663 (hex 0x1237) using the table below and you're connected with no sign-up required.

Why index it now

The chain's history is tiny — full-range eth_getLogs scans are still practical in a way they never are on mature chains. If you're building RWA tooling or analytics on Robinhood Chain, indexing from genesis today is a genuine early-mover advantage.
