Build on Robinhood Chain and Robinhood Crypto: verified network constants, a chain SDK, a read-only MCP server, runnable examples, and 64 build prompts.
Build on Robinhood Chain and Robinhood Crypto. Tools, runnable examples, and 64 build prompts.
Quick start · Build prompts · Examples · Networks · Deploy
Robinhood opened up to developers on two fronts: Robinhood Chain, an Arbitrum Orbit L2 that went to public mainnet on 2026-07-01 with permissionless contract deploys, and the Robinhood Crypto REST API for programmatic trading. A third front, agentic trading over MCP, currently covers equities and options with crypto support announced as rolling out.
This repository is the practical layer on top of all three: network constants you can trust, code that runs as written, and a prompt library you can hand to a coding agent to build any piece of it.
The official documentation tells you what the endpoints are. It does not tell you how to wire a datafeed into a candlestick chart, how to structure a strategy loop that will not liquidate you at 4am on a 24/7 venue, or how to get the same codebase onto five different hosts. That gap is what this fills.
Every fact here was verified against a live source. Network parameters were confirmed by direct RPC calls rather than copied from documentation. Anything that could not be verified is labeled UNVERIFIED inline with instructions for checking it yourself.
