Robinhood Chain RPC URL
The Robinhood Chain public mainnet RPC URL, as published in Robinhood's own add-network-to-wallet documentation, is https://rpc.mainnet.chain.robinhood.com. It serves chain ID 4663, gas is denominated in ETH, and the canonical block explorer is https://robinhoodchain.blockscout.com. Robinhood's docs explicitly note that this endpoint is rate-limited and is not recommended for production workloads.
This page is a plain reference: what the URL is, where it comes from, how to paste it into a wallet correctly, and what to do when the public endpoint throttles you. Treat Robinhood's docs as the authoritative source — parameters can change and this page is dated below.

The canonical parameters
Network name: Robinhood Chain. Chain ID: 4663. RPC URL: https://rpc.mainnet.chain.robinhood.com. Currency symbol: ETH. Block explorer URL: https://robinhoodchain.blockscout.com. These five fields are exactly what Robinhood's add-network-to-wallet page instructs you to paste into a wallet's Add a custom network form.
Why the public RPC is not for production
Robinhood's connecting documentation warns that the public endpoint is rate-limited and is not intended for indexers, bots or high-volume scripts. For a single user signing occasional transactions it is fine. For anything that batches reads or fans out subscriptions, expect HTTP 429 responses and plan for exponential backoff, request coalescing, or a paid RPC provider that supports chain 4663.
How to paste it into MetaMask, Rabby or Phantom
Open the wallet's network dropdown, choose Add a custom network, paste each field exactly, and save. Robinhood's docs explicitly document MetaMask and Phantom flows and note that other EVM wallets may support custom networks — check the wallet vendor for the current supported list rather than trusting a third-party matrix.
Limitations of this page
We do not publish latency, uptime, throughput or a specific rate-limit number for the public RPC — Robinhood does not commit to those in its docs, and any number here would go stale. If you need SLAs, use a paid provider with a written commitment.
Frequently asked questions
What is the Robinhood Chain mainnet RPC URL? https://rpc.mainnet.chain.robinhood.com, as published on Robinhood's add-network-to-wallet documentation page. It serves chain ID 4663 with ETH gas. Is the public RPC free? Yes, but Robinhood's connecting docs mark it as rate-limited and not recommended for production. For any bulk or automated workload you should use a paid RPC provider that supports chain 4663. Does Robinhood publish a websocket endpoint? See Robinhood's JSON-RPC documentation for the current list of supported transports and methods. If a websocket is not listed there, treat it as unavailable rather than guessing a URL. What if the RPC returns 429 errors? That is the documented rate-limit behaviour. Back off, batch requests, or switch to a paid provider that supports chain 4663.
