How to add Robinhood Chain to MetaMask: RPC, chain ID and explorer

Robinhood Chain's network settings for MetaMask (chain ID 4663, the RPC URL and the explorer), the built-in and manual steps, and how to get ETH onto the chain.

Robinhood Chain is Robinhood's own blockchain: an Arbitrum layer 2 on Ethereum, live on mainnet since July 1, 2026, with ETH as its gas token and chain ID 4663. MetaMask already lists it as a built-in network, so in most wallets adding it takes three clicks. If yours doesn't show it, the settings below add it by hand.

Robinhood Chain network settings

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

These come from Robinhood's own documentation. The public RPC is rate-limited, and Robinhood says it is not meant for production use: it is fine for a wallet, but an app with real traffic should use an RPC provider. Robinhood's docs recommend Alchemy and list several others.

Add Robinhood Chain from MetaMask's network list

Open MetaMask and click the menu.
Open Networks, then Additional networks.
Find Robinhood Chain and click Add.

Robinhood also keeps an add-network page with one-click buttons for the common wallets. If you use the Robinhood Wallet app, there is nothing to add: it supports Robinhood Chain natively.

Add Robinhood Chain to MetaMask manually

If Robinhood Chain isn't in your list, for example on an older version of MetaMask:

Open the menu, then Networks, then Add a custom network. On mobile, open the network list, choose the Custom tab, then Add a custom network.
Fill in the five fields from the table above.
Click Save, and switch to Robinhood Chain.

MetaMask checks the chain ID against the RPC URL as you type. If it warns that the ID doesn't match, check both values against the table; a typo in either is the usual cause.

Robinhood Chain testnet settings

Robinhood Chain also has a public testnet, for developers who want to test their own contracts before mainnet.

Field	Value
Network name	Robinhood Chain Testnet
RPC URL	`https://rpc.testnet.chain.robinhood.com`
Chain ID	`46630`
Currency symbol	ETH
Block explorer URL	`https://explorer.testnet.chain.robinhood.com`

Test ETH comes from the faucet at faucet.testnet.chain.robinhood.com. Launchpads such as Pons run on mainnet only, so the testnet is not a place to rehearse a meme coin launch.

How to get ETH onto Robinhood Chain

Every transaction on Robinhood Chain pays gas in ETH, so a new wallet needs some before it can do anything. There are three ways to get it there:

The official bridge. Robinhood's bridging docs point to the Arbitrum bridge, from Ethereum mainnet. A deposit arrives in about 10 minutes. Going back to Ethereum takes about 7 days, the challenge period, and then a claim transaction on Ethereum that pays Ethereum gas.
Third-party bridges. Robinhood's docs also name Stargate, Transporter, Relay, Across, LI.FI and 0x. They are often faster, especially on the way back to Ethereum, and each charges its own fee.
The Robinhood app. In the US, outside New York, you can send ETH from the Robinhood app straight to your wallet on Robinhood Chain.

What's different on Robinhood Chain

Gas is ETH, in two parts. Each transaction pays an execution fee on Robinhood Chain and a data fee for posting to Ethereum, bundled into one gas cost.
Blocks come every 100 milliseconds.
Paying more gas doesn't put you first. Transactions are ordered as they arrive, not by fee.

Next: launch a token on Robinhood Chain

Once your wallet is on Robinhood Chain with some ETH, you can launch a token there in one signature. How to launch a meme coin on Robinhood Chain covers the steps with Pons, a meme coin launchpad on the chain.

Modus launches on Pons from a chat, as part of the same project as the product the token belongs to. When it needs your wallet, a connect card opens in the chat, so you never paste an address or a key, and your own wallet signs every transaction.

Frequently asked questions

What is Robinhood Chain's chain ID?

4663, or 0x1237 in hexadecimal. The testnet's chain ID is 46630.

What is Robinhood Chain's RPC URL?

https://rpc.mainnet.chain.robinhood.com. It is Robinhood's public endpoint and it is rate-limited; apps with real traffic should use an RPC provider.

Which block explorer does Robinhood Chain use?

Blockscout, at https://robinhoodchain.blockscout.com.

Is Robinhood Chain an Ethereum layer 2?

Yes. It is built on Arbitrum's technology, settles to Ethereum, and uses Ethereum blobs for data availability.

Why don't I see my ETH on Robinhood Chain?

Check that MetaMask is switched to Robinhood Chain, not Ethereum. If you just bridged, a deposit through the official bridge takes about 10 minutes to arrive.
