Robinhood Chain in MetaMask: Manual Setup Guide

Robinhood Chain can be added to MetaMask manually. The important part is using the correct network details: chain ID 4663, the public RPC https://rpc.mainnet.chain.robinhood.com, and the Blockscout explorer at Robinhood Chain Blockscout. Gas on Robinhood Chain is paid in ETH.

Robinhood Chain network details for MetaMask

Robinhood Chain is an Ethereum Layer 2 network built by Robinhood on Arbitrum Orbit technology. If MetaMask does not already show it in the network list, the safe approach is to add it by hand and verify each field before saving.

Use these values:

If any source shows a different chain ID or a different main public RPC, treat that as a warning sign and double-check it against the official docs at Robinhood Chain docs.

What you need before connecting Robinhood Chain

The setup itself is simple. Most mistakes happen before the first transaction, not during it.

Have these basics ready:

1. MetaMask installed and unlocked.
2. A small amount of ETH for gas. Robinhood Chain uses ETH for transaction fees.
3. The official network details copied from a trusted source. The clean reference is Robinhood Chain docs.
4. The explorer bookmarked. The correct block explorer is Robinhood Chain Blockscout.

If you plan to move assets onto the chain after setup, keep in mind that the wallet network and the asset network need to match. Seeing ETH in MetaMask on another chain does not mean that same ETH is available for gas on Robinhood Chain.

How to add Robinhood Chain to MetaMask manually

The exact screen labels can vary a bit across MetaMask browser extension and mobile app versions. The process is still the same: open network settings, choose to add a custom network, then enter the chain details carefully.

Step 1: Open MetaMask network settings

Open MetaMask and unlock the wallet.

Find the network selector near the top of the wallet interface. Open it and choose the option to add a network or add a custom network.

Step 2: Enter the Robinhood Chain settings

Fill in the network fields with the Robinhood Chain values.

Use:

• Network name: Robinhood Chain
• RPC URL: https://rpc.mainnet.chain.robinhood.com
• Chain ID: 4663
• Currency symbol: ETH
• Block explorer URL: https://robinhoodchain.blockscout.com

Take a second look before saving. The chain ID matters because it tells MetaMask which network it is talking to. A wrong chain ID means the wallet may point somewhere else entirely.

Step 3: Save the network

Save the custom network entry.

After saving, MetaMask should switch to Robinhood Chain automatically in many cases. If it does not, go back to the network selector and switch to Robinhood Chain manually.

Step 4: Confirm the wallet is actually on Robinhood Chain

Do not stop after the network appears in the list. Confirm that MetaMask is using the right network.

Check these items:

• The selected network reads Robinhood Chain.
• The network details show chain ID 4663.
• The native gas token is ETH.
• The explorer field points to https://robinhoodchain.blockscout.com.

That is the minimum safe verification.

How to verify Robinhood Chain after setup

A network entry in MetaMask is only half the job. The next step is making sure the RPC and explorer behave like Robinhood Chain, not just like any EVM chain.

Check the explorer with your wallet address

Copy your wallet address from MetaMask.

Open Robinhood Chain Blockscout and search that address. If the network is correct, Blockscout should open an address page for that same wallet on Robinhood Chain.

If the explorer cannot find the address page, or the page format looks wrong, recheck the explorer URL and the RPC URL.

Check for ETH as the gas token

MetaMask should show ETH as the native token for fees on Robinhood Chain. That does not guarantee you already hold spendable ETH on that chain, but it does confirm the wallet is using the correct gas symbol.

This point matters because many on-chain errors come from confusion between token balances and gas balances. A wallet can hold other assets on Robinhood Chain and still fail to send a transaction if there is no ETH available for gas.

Cross-check with the official docs

If anything looks off, compare your saved settings with Robinhood Chain docs. That is the fastest way to catch a copied typo in the RPC, explorer, or chain ID.

What happens after MetaMask is connected to Robinhood Chain

Once the network is added and selected, MetaMask can connect to apps that support Robinhood Chain. Those apps may prompt the wallet to connect, and MetaMask will ask for signature approval or transaction approval as needed.

Two practical notes matter here.

First, transactions still require ETH for gas. Adding the network alone does not fund the wallet.

Second, token balances may not appear automatically. On EVM networks, wallets sometimes need a token imported manually before the balance shows in the asset list. If that happens, verify the token contract address on the explorer before adding it to MetaMask.

Robinhood Chain has active DEX trading across many pools and venues in the public market data tracked here, but that tracked data covers the most active pools rather than the entire chain. So if a token looks missing in one app or feed, that does not by itself mean the network setup failed.

If your next step is using a non-custodial app on Robinhood Chain, including RobinSwap, the safest pattern is the same each time: confirm the wallet is on Robinhood Chain first, then confirm the token contract on the explorer, then sign.

Why chain ID 4663 matters

Chain ID is the single most important number in this setup. Robinhood Chain’s verified chain ID is 4663.

MetaMask uses chain ID to distinguish one EVM network from another. The network name can be typed any way a user wants, but the chain ID is what the wallet relies on at the protocol level.

That is why a custom network called “Robinhood Chain” is not enough on its own. If the chain ID is wrong, the label can look correct while the connection is not.

The same logic applies to the RPC URL. A typo in the RPC can stop the wallet from connecting, or point it at a service that does not match the chain you intended to use.

Common mistakes

• Using the wrong chain ID. Robinhood Chain uses 4663.
• Forgetting that gas is paid in ETH. A token balance is not the same thing as having ETH for fees.
• Trusting copied settings from random posts. Cross-check the values with Robinhood Chain docs.
• Not checking the explorer after setup. Search your address on Robinhood Chain Blockscout to confirm the setup is real.
• Importing a token before verifying the contract. Use the explorer to verify the contract address first.
• Assuming assets on another network are available here. The wallet address may be the same across EVM chains, but balances are chain-specific.

Robinhood Chain is straightforward to add to MetaMask, but brand-new network setups are still a common place for avoidable errors. Slow is better than wrong.
