Connecting to Robinhood Chain

Every value on this page is reproduced verbatim from docs.robinhood.com/chain as documented on 2026-09-09. Check an address or URL against the live docs before moving funds.

Network Configuration

The block explorer values are given by the docs exactly as shown — bare hostnames, no scheme. Elsewhere in the same doc set the explorer is used with a scheme, e.g. https://robinhoodchain.blockscout.com/address/<contract_address> and the Blockscout verification API at https://robinhoodchain.blockscout.com/api/.

Public Endpoints

The docs are explicit about the tradeoff: "The following public endpoints are available but are rate-limited and not recommended for production use. For production, use a provider."

The full-node guide notes of the feed URL: "The feed URL must be wss://, not https://."

Discrepancy worth knowing: the Connecting page and the Deploy a Contract page both give the mainnet public RPC as https://rpc.mainnet.chain.robinhood.com (no trailing slash), while the Add-network-to-your-wallet page gives it as https://rpc.mainnet.chain.robinhood.com/ (with a trailing slash). Both forms are documented; the testnet URL is given without a trailing slash on every page.

Provider Endpoints

"Alchemy is the recommended infrastructure provider for building on Robinhood Chain." You create an app on Robinhood Chain to obtain an API key.

"For historical reads and indexing, use an archive endpoint — available through providers such as Alchemy."

Alchemy's documented service surface on this chain: Node API (standard JSON-RPC and Websocket), Data API ("Instant, reliable access to indexed blockchain data like token balances, transaction history, NFTs, and portfolio activity"), and Gasless Transaction Infrastructure (programmable wallets with gas sponsorship, batched transactions, policies, spending controls) — see account-abstraction.md.

Other providers

"Robinhood Chain is also supported by QuickNode, Blockdaemon, dRPC, and Validation Cloud. Sign up directly with your provider to get an endpoint."

QuickNode endpoints follow the template:

https://{ENDPOINT}.robinhood-mainnet.quiknode.pro/{TOKEN}

The full-node page lists a slightly longer provider set with landing pages: Quicknode (https://www.quicknode.com/chains/robinhood), Blockdaemon (https://docs.blockdaemon.com/docs/how-to-connect-to-robinhood), dRPC (https://drpc.org/chainlist/robinhood-testnet-rpc), Validation Cloud (https://www.validationcloud.io/robinhood), Chainstack (https://chainstack.com/build-better-with-robinhood-chain/), GlobalStake (https://GlobalStake.io).

Adding the Network to a Wallet

Robinhood Wallet

"Robinhood Wallet provides support for Robinhood Chain." The documented steps are: download Robinhood Wallet (requires iOS or Android), then create a wallet.

Browser wallets

"Robinhood Chain is compatible with EVM Wallets (MetaMask and more)." The docs page offers a click-to-add widget; in the 2026-09-09 capture that widget had not rendered (the page shows only "Loading wallet connection..."), so the automatic-add targets are not recoverable from this source.

To add manually to MetaMask, the docs give these fields:

Toolchain Configuration

The Deploy a Contract guide gives working configuration for both major toolchains.

Foundry (environment + verification):

export RH_RPC_URL=https://rpc.mainnet.chain.robinhood.com

forge verify-contract <contract_address> \
  src/HelloRobinhood.sol:HelloRobinhood \
  --chain-id 4663 \
  --rpc-url $RH_RPC_URL \
  --verifier blockscout \
  --verifier-url https://robinhoodchain.blockscout.com/api/

Hardhat network + custom-chain block:

networks: {
  robinhood: {
    url: process.env.RH_RPC_URL,
    chainId: 4663,
    accounts: [process.env.PRIVATE_KEY],
  },
},
etherscan: {
  apiKey: { robinhood: "empty" },
  customChains: [
    {
      network: "robinhood",
      chainId: 4663,
      urls: {
        apiURL: "https://robinhoodchain.blockscout.com/api",
        browserURL: "https://robinhoodchain.blockscout.com/",
      },
    },
  ],
},

For testnet, the docs say: "set RH_RPC_URL to the testnet RPC, use chain ID 46630, and verify against https://explorer.testnet.chain.robinhood.com/api/."

Running Your Own Node

If you need your own endpoint rather than a hosted one, the node is Nitro. Ports are 8547 (HTTP) and 8548 (WS); the container image documented is offchainlabs/nitro-node:v3.11.2-3599aca; the chain runs ArbOS 61. A node needs both an L1 execution RPC endpoint and an L1 beacon (consensus) endpoint, "required to read blob data". The docs' own caveat: "If you don't already know why you need your own node, you probably don't."

Bringing Funds Onto the Chain

"To move funds onto Robinhood Chain, use the canonical Arbitrum bridge or one of several cross-chain routes." The canonical route deposits in roughly 10 minutes and withdraws subject to a ~7-day challenge period; see transaction-finality.md for why the withdrawal delay is not the same thing as finality.
