Add Robinhood Chain to your wallet, bridge ETH onto it, find a mint on OpenSea and check what you got. Every step verified on 23 September 2026, with gas measured live on chain 4663.

Nearly every guide written about Robinhood Chain is aimed at people launching a collection. This one is for the other side: you want to mint something, and you have never used this chain before.
It takes four steps, costs a couple of cents in gas, and the only part that takes real time is moving ETH onto the chain. Every figure below was checked on 23 September 2026, and the gas numbers were measured on the chain itself that day.
First, the thing to get straight before anything else: Robinhood Chain is not your Robinhood account. It is a public Ethereum Layer 2, built on the Arbitrum stack, and its own support documentation says it operates independently of the main Robinhood app and does not affect your investments, crypto balances or portfolio. Your brokerage balance cannot mint anything. You need a self-custody wallet and ETH inside it.
You have three ways in, in order of how little work they are.
Robinhood Wallet supports the chain natively, with no manual setup, according to the official support article. Worth knowing: that wallet can currently only receive NFTs, not send them, so treat it as somewhere to mint into rather than somewhere to trade from.
chainlist.org has chain 4663 listed. Search for it, connect, and it adds the network in one click. We confirmed the chain is in the public chain registry that Chainlist reads, so this works with MetaMask, Rabby and anything else that speaks the same standard.
By hand, in any EVM wallet, using the official values:

There is no separate network token to buy. Gas is paid in ETH. The testnet, if you want to practise, is chain 46630.
ETH in your wallet on Ethereum mainnet is not ETH on Robinhood Chain. It has to be bridged.
The canonical bridge is the safest route and the official one: portal.arbitrum.io/bridge, with Robinhood Chain as the destination and Ethereum as the source. It is trustless and inherits its security from Ethereum. Deposits take about 10 minutes.

The catch is the way back out. Withdrawing to Ethereum through the canonical bridge takes about 7 days, because of the challenge period that optimistic rollups use. That is normal, not a fault, but decide before you bridge that you are happy leaving funds there for a while.
One reassuring detail from the documentation: if a deposit fails, for example because of insufficient gas, the funds are not lost. They can be redeemed manually from the bridge interface within 7 days.
Faster third-party routes exist and the chain's documentation names them: LayerZero and Stargate, Chainlink's CCIP through Transporter, Relay, Across, and aggregators like LiFi and 0x. These settle in seconds to minutes, in both directions, and they charge for the privilege. They are also more trust than the canonical bridge, since you are relying on the bridge operator rather than on Ethereum.
Or skip bridging entirely. OpenSea lets you add funds with Apple Pay or a debit or credit card directly for Robinhood Chain. For someone who just wants to mint one thing, that is by far the shortest path.
OpenSea has supported Robinhood Chain since 11 July 2026, ten days after mainnet, and it is where most mints on this chain happen. The chain has its own hub at opensea.io/discover/chain/robinhood, and everything works in OpenSea's mobile app too.

Before you click mint, do one check that takes ten seconds and prevents the most common loss on any chain: find the collection by its contract address, not by its name.
Search results are not proof. Anyone can create a collection using a name, a logo and a description that match a real project. We know this first hand: an impersonator used the obvious Ethernal Cubs slug on OpenSea, and it was delisted on 19 September 2026, but only after it had been live. Get the contract address from the project's own site, its pinned post or its Discord, then open the collection from that address.
Minting is a normal transaction: connect the wallet, confirm, wait a few seconds. Robinhood Chain produces blocks quickly, so confirmation is fast.
What it costs. We measured the chain directly on 23 September 2026, at block 69,943,705. The gas price was 0.052 gwei. With ETH around $2,756 that works out as:
So a mint costs a couple of cents. An early gas subsidy on this chain has expired, so those are the real, unsubsidised numbers.
Check the result in two places. The block explorer at robinhoodchain.blockscout.com shows the transaction, the token and the contract it came from. OpenSea shows the item in your wallet, usually within a minute or two. If the explorer shows it and OpenSea does not, wait: the chain is the truth and the marketplace is catching up.

Ethernal Cubs is our own collection, so this is an example and not a recommendation, but it is a real one with dates you can hold us to.
There are 3,333 Orbs on Robinhood Chain. The whitelist mint opens on 29 October 2026 at 14:00 UTC and runs to 5 November. The mint price is zero, so the only cost is the couple of cents of gas above. Whitelist spots are earned before then on the board at ethernalcubs.ai.
If you want to follow every step in this guide exactly, that is a mint to practise on: add the network, bridge or card in a little ETH, resolve our collection from its contract address rather than from a search, and check the result on the explorer afterwards.
Chain ID, block height and gas price were measured by direct JSON-RPC calls to https://rpc.mainnet.chain.robinhood.com on 23 September 2026.
