How to Add Robinhood Chain to MetaMask

Nock Terminal Editorial Team

To add Robinhood Chain to MetaMask, open the network dropdown, choose Add a custom network, and enter the parameters Robinhood publishes at docs.robinhood.com/chain/add-network-to-wallet: network name Robinhood Chain, chain ID 4663, RPC URL https://rpc.mainnet.chain.robinhood.com, currency symbol ETH, and block explorer https://robinhoodchain.blockscout.com. Save the network and switch to it before you attempt any transaction.

Robinhood Wallet supports the chain natively. For browser wallets, Robinhood's add-network page explicitly offers MetaMask and Phantom, and notes that other EVM wallets may support custom networks. This guide does not claim compatibility with any wallet not documented by Robinhood — check your wallet vendor and the Robinhood docs for the current supported list.

Which wallets support Robinhood Chain?

Robinhood Wallet supports Robinhood Chain natively. For browser wallets, Robinhood's add-network-to-wallet documentation explicitly offers MetaMask and Phantom connection flows and notes that other EVM wallets may support custom networks. This guide does not list specific third-party wallet brands or hardware devices beyond what Robinhood's own docs currently document — check your wallet vendor's documentation and Robinhood's add-network page for the current supported list before you rely on any specific product.

Automatic add vs manual add

Some dApps, including Nock Terminal, can trigger MetaMask's wallet_addEthereumChain prompt so you only click Approve. Automatic add uses the same parameters as manual add — chain ID 4663, ETH gas, the public RPC — so the end state is identical. If the automatic prompt fails (older wallet versions, disabled permissions), fall back to the manual form above.

RPC rate limits and provider redundancy

Robinhood's connecting documentation states that the public RPC at https://rpc.mainnet.chain.robinhood.com is rate-limited and is not recommended for production use. Treat the public endpoint as a convenience for connecting a wallet and signing occasional transactions; for bots, indexers, bulk scripts or any production workload, plan for rate-limit errors, implement backoff, and use a paid or self-hosted RPC provider. Nothing on this page promises uptime, throughput or fitness for a specific purpose — the Robinhood docs are the authoritative source.

Troubleshooting: network mismatch and wrong-chain errors

If a swap fails with a chain-mismatch error, the most common cause is a wallet still connected to a previous network. Open the wallet, switch to Robinhood Chain, refresh the dApp, and reconnect. If Nock Terminal shows Add Robinhood Chain even though you added it manually, check that the chain ID matches 4663 exactly — some tutorials list the testnet ID, which will not match.

Steps

  1. 1
    Open your wallet's custom network form
    In MetaMask, click the network dropdown at the top and choose Add a custom network. Any browser wallet that Robinhood's add-network page documents (currently MetaMask and Phantom) has an equivalent form; other EVM wallets may support custom networks — check the wallet vendor's docs.
  2. 2
    Enter the Robinhood Chain mainnet parameters
    Network name: Robinhood Chain. Chain ID: 4663. New RPC URL: https://rpc.mainnet.chain.robinhood.com. Currency symbol: ETH. Block explorer URL: https://robinhoodchain.blockscout.com. Save.
  3. 3
    Switch to the network and confirm the connection
    Select Robinhood Chain from the network dropdown. Your address is the same as on any other EVM chain, but the balance starts at zero until you bridge ETH. Nock Terminal's connect flow will trigger the same custom-network prompt automatically if you have not added the chain yet.
  4. 4
    Do not confuse mainnet 4663 with the testnet
    Robinhood Chain's testnet uses a different chain ID (46630 at time of writing). Mainnet and testnet are separate networks with separate state and separate token balances — testnet assets have no mainnet value, and vice versa. A wallet configuration alone does not move funds between them; a chain-ID or RPC mismatch means a transaction you sign would broadcast to the wrong network. Verify the chain ID in your wallet before signing or bridging.
  5. 5
    Test with a read-only action first
    Before any funded transaction, open Nock Terminal or Blockscout and confirm the connected chain is 4663. If a dApp shows a Wrong Network warning, either the dApp does not support Robinhood Chain yet or your wallet is on a different chain.

What is the Robinhood Chain ID? Chain ID 4663 for mainnet. The gas token is ETH, and the canonical block explorer is https://robinhoodchain.blockscout.com. Can I use MetaMask on Robinhood Chain? Yes. Robinhood's add-network-to-wallet page explicitly offers MetaMask (and Phantom) connection flows for chain 4663, and notes that other EVM wallets may support custom networks. Consult Robinhood's own docs for the current list of documented wallets. Is there a Robinhood Chain testnet? Yes. Its chain ID is 46630 at the time of writing, distinct from mainnet 4663. Mainnet and testnet are separate networks with separate state and balances; testnet assets have no mainnet value. Verify the chain ID in your wallet before signing or bridging so a transaction does not broadcast to the wrong network. Does adding Robinhood Chain to MetaMask cost anything? No. Adding a custom network is free. You only pay ETH gas when you actually send a transaction on the network.
