Robinhood Chain RPC

Robinhood Chain and the equities REST API. One key.

Standard Ethereum JSON-RPC for Robinhood Chain (reads, logs, and transaction broadcast) plus the the equities REST API API for CLOB state, served from a self-operated node fleet. Stream the live data; use RPC for point reads and transaction submission.

Two surfaces

Two execution surfaces, one credential.

Robinhood Chain runs an EVM and a CLOB L1 side by side. We serve both from a self-operated node fleet: standard Ethereum JSON-RPC for Robinhood Chain state and transactions, and the the equities REST API /info API for market and account state on the exchange. The same API key authenticates either path.

Robinhood Chain JSON-RPC

JSON-RPC / HTTPS

https://rpc.robinhoodrpc.io

The usual eth_* set: read contract state, index logs and events, estimate gas, and broadcast signed transactions: contract calls, transfers, bridging. If your tooling speaks Ethereum, it speaks this.

the equities REST API

HTTPS POST

https://api.robinhoodrpc.io/info

The read API for the the equities REST API L1, the perps and spot CLOB. Market metadata, L2 book snapshots, asset contexts with mark price, funding, and open interest, plus per-wallet state: open orders, fills, positions, funding history, and exchange status.

Quickstart

First response in under five minutes.

No new client library. viem, ethers, and web3.py work as-is. Set one header and point them at the endpoint.

  1. Get an API key

    One key authenticates Robinhood Chain RPC, the equities REST API, and the gRPC streams across both plans. Historical exports are requested manually.

  2. Point your client at the endpoint

    Send JSON-RPC over HTTPS to rpc.robinhoodrpc.io with the key in the x-api-key header.

  3. Read, then broadcast

    eth_call and eth_getLogs for state; eth_sendRawTransaction when you are ready to write.

Timed from key creation to the first JSON-RPC response.

FAQ

Common questions

A data and RPC provider for Robinhood Chain. We stream real-time market data over gRPC, serve Robinhood Chain/the equities REST API RPC, and prepare historical exports and custom datasets on request.

Robinhood Chain transactions, yes, via eth_sendRawTransaction on our RPC. the equities REST API CLOB orders are placed through Robinhood Chain's signed-action exchange API, separate from EVM RPC.

Streams are sub-second. We run a self-operated Robinhood Chain node fleet with automated failover and redundancy.
