Robinhood Chain in MetaMask: RPC, Chain ID, Explorer

Robinhood Chain can be added to MetaMask as a custom network with chain ID 4663, the public RPC URL, and the Blockscout explorer URL. Robinhood Chain is an Ethereum Layer 2 built on Arbitrum Orbit technology, and gas on the network is paid in ETH, so those are the settings that matter before any bridge or swap.

The exact Robinhood Chain settings

The safest starting point is the official docs. If MetaMask asks for the standard custom-network fields, use these values.

A couple of notes help avoid confusion.

• Chain ID 4663 is the network identifier MetaMask uses to distinguish Robinhood Chain from other networks.
• ETH is the gas token. That does not mean Ethereum mainnet. It means transaction fees on Robinhood Chain are paid in ETH on Robinhood Chain.
• The Blockscout explorer is for checking addresses, transactions, and contracts on this network.

How to add Robinhood Chain to MetaMask

MetaMask layouts change a bit between browser extension and mobile, but the flow is usually the same.

1. Open MetaMask.
2. Find the network selector near the top of the wallet.
3. Choose the option to add a network manually or add a custom network.
4. Enter the five fields from the table above.
5. Save the network.
6. Switch MetaMask to Robinhood Chain after saving.

If MetaMask asks for a network name, use Robinhood Chain. If it asks for a native currency symbol, use ETH because that is the token used for gas on this chain.

The part worth slowing down for is the RPC URL. Enter the public RPC exactly as listed: https://rpc.mainnet.chain.robinhood.com.

The explorer field also matters more than beginners sometimes expect. Adding https://robinhoodchain.blockscout.com makes it easier to inspect transactions and confirm that a wallet or dapp is looking at the right chain.

How to confirm MetaMask is on the right network

Adding a network is only half the job. Before moving funds, confirm the wallet is actually pointed at Robinhood Chain.

Check the network label and chain ID

Start with the obvious check.

1. Open the active network details in MetaMask.
2. Make sure the selected network reads Robinhood Chain.
3. Make sure the chain ID shown there is 4663.

If the chain ID is wrong, the wallet is on the wrong network even if the name looks similar.

Check the gas token

Next, confirm the wallet expects ETH for gas.

That is an easy sanity check because Robinhood Chain uses ETH for fees. If a setup shows a different native gas token, recheck the network details before doing anything else.

Check the explorer

The cleanest external check is the explorer.

1. Open Blockscout for Robinhood Chain.
2. Copy your wallet address from MetaMask.
3. Paste that address into the explorer search bar.

If the explorer resolves your address page, you are checking against the right network explorer. A new wallet may still show no transactions or no assets there, and that is normal. An empty history does not mean the setup is broken.

Check what connected apps are asking for

When a dapp asks MetaMask to switch networks, the requested chain should be 4663 for Robinhood Chain. If the request points to something else, stop and verify before approving.

This matters because Robinhood Chain is active enough that a mismatch can be confusing. On October 21, 2026, GeckoTerminal-tracked activity covered 226 pools, about $957 million in 24-hour volume, and roughly 1.16 million trades. That tracked volume only covers the most active pools, not the entire chain, but it is enough to make a wrong-wallet-network problem look like a broken app when it is usually just a settings issue.

What the RPC and explorer are for

These two fields are easy to copy and easy to misunderstand.

The RPC URL is the connection point MetaMask uses to read the chain and send signed transactions. For Robinhood Chain, the public endpoint is https://rpc.mainnet.chain.robinhood.com.

The Blockscout explorer URL is different. It does not route transactions for the wallet. It gives MetaMask and the user a reference page for viewing addresses and transaction history on Robinhood Chain at https://robinhoodchain.blockscout.com.

If MetaMask works but the explorer link is missing, the network can still function. It is just harder to verify what happened after a transaction. For beginners, that missing visibility is not ideal.

What to check before bridging or swapping

Once the network is added, do one short preflight check before using any Robinhood Chain app, including a non-custodial app such as RobinSwap.

1. Confirm MetaMask is switched to Robinhood Chain.
2. Confirm the chain ID is 4663.
3. Confirm you will have ETH on Robinhood Chain for gas.
4. Confirm the app itself says Robinhood Chain somewhere in its network state.
5. If you inspect the destination address or transaction later, confirm it appears on the Robinhood Chain Blockscout explorer.

One beginner mistake is assuming ETH on Ethereum mainnet, Base, or Arbitrum automatically pays gas everywhere. It does not. Robinhood Chain uses ETH as gas, but it still has to be ETH on Robinhood Chain.

Another mild confusion point is quote assets. On Robinhood Chain, common quote assets across DEX pools include WETH, USDG, USDC, and USDe. Seeing WETH in a trading pair is normal, but the native gas asset for the chain is still ETH.

Common mistakes

• Entering the wrong chain ID. For Robinhood Chain, it is 4663.
• Pasting the wrong RPC URL. Use https://rpc.mainnet.chain.robinhood.com.
• Forgetting the explorer URL. The correct Blockscout address is https://robinhoodchain.blockscout.com.
• Assuming ETH on another network will pay Robinhood Chain gas.
• Confusing WETH in trading pairs with the chain’s native gas token.
• Approving a dapp network switch without checking whether it is asking for chain ID 4663.

If those five setup fields are correct and MetaMask shows Robinhood Chain with ETH as gas, the wallet is configured well enough for basic use.
