How to Bridge ETH to Robinhood Chain (Measured)
There is no faucet for Robinhood Chain mainnet, so the only way to fund a wallet is to bridge ETH from a chain you already hold it on. We ran the transfer from Arbitrum and timed every part of it — deposit to credited balance in about two seconds, with a cost you can see below to the wei.
The quick version
- Hold ETH on Ethereum, Arbitrum, Base or Optimism.
- Open a bridge, pick your source chain, and set Robinhood Chain as the destination.
- Enter an amount, approve the transaction in your wallet, and wait.
- Add Robinhood Chain to your wallet if you have not yet, and your balance appears.
If the network is not in your wallet yet, our one-click add-to-MetaMask guide is the fastest way to set it up first.
What it actually cost and how long it took
Rather than estimate, here is a real transfer we made on 30 August 2026, from Arbitrum One to Robinhood Chain.
A single transfer via a bridge aggregator on 30 August 2026. The ~4.8% is dominated by the fixed component of a very small transfer; a larger amount in one transaction is proportionally far cheaper.
Which chains you can bridge from
The practical routes into Robinhood Chain are the major ETH-native networks. All of them settle in ETH on both sides, so there is no token selection to get wrong.
| Source chain | Native asset | Typical use |
|---|---|---|
| Ethereum | ETH | Largest liquidity, higher source-chain gas |
| Arbitrum | ETH | Cheap source gas, what we tested |
| Base | ETH | Cheap source gas, widely held |
| Optimism | ETH | Cheap source gas |
How bridging works, briefly
A bridge does not physically move your ETH between chains — it locks or takes your ETH on the source chain and releases an equivalent amount to your address on the destination. Modern bridge aggregators route through whichever underlying path is cheapest and fastest at the moment you quote, which is why the exact amount received varies slightly from quote to quote.
- The amount received is always a little less than sent. The difference is the route’s cost plus any aggregator fee, shown in the quote before you sign.
- Speed depends on the route, not just the chains. Our Arbitrum transfer settled in about two seconds; other routes and larger amounts can take longer.
- Your destination address is the same as your source address. The same wallet holds an independent balance on each chain.
Staying safe
Bridging is one of the higher-risk actions in crypto, mostly because it is a common target for phishing. A few rules that cost nothing:
- Confirm the destination chain ID reads
4663before you sign. - Check the amount you will receive in the quote, not just the amount you send.
- Never enter a seed phrase or private key to “complete” a bridge. No legitimate bridge asks for one.
- Start with a small test amount the first time you use any bridge route.
Frequently asked questions
How do I bridge ETH to Robinhood Chain?
Hold ETH on Ethereum, Arbitrum, Base or Optimism, open a bridge, set Robinhood Chain (chain ID 4663) as the destination, enter an amount and approve it in your wallet. Our Arbitrum transfer credited in about two seconds.
How long does bridging to Robinhood Chain take?
Our measured Arbitrum-to-Robinhood transfer took roughly two seconds from deposit confirmation to a credited balance. Times vary with the route and amount.
Is there a Robinhood Chain faucet?
Not for mainnet. Bridging ETH from another chain is the way to fund a wallet. The testnet (chain ID 46630) is a separate network.
Why did I receive slightly less than I bridged?
The shortfall is the bridge route’s cost plus any aggregator fee, both shown in the quote before you sign. On small transfers the fixed component makes this look like a larger percentage than it is on bigger amounts.
