Sailing between Ethereum and Robinhood Chain
Ferry

Board on Ethereum. Step off holding stocks.

One transaction on Ethereum carries your ETH across Robinhood's own bridge and buys tokenized stocks on the other side — Nvidia, Tesla, Apple and 64 more — straight into your wallet, with gas money waiting for you there. About 10 minutes.

  • No contract of ours
  • Robinhood's own bridge
  • Your price, or nothing bought
  • Same address, both shores

The crossing

One signature on Ethereum. Shares on the other shore.

Robinhood Chain is an Arbitrum chain that settles on Ethereum, and its bridge can carry a message as well as money. Ferry's ticket carries both: your ETH, and the purchase to make with it when it lands.

01 · BOARD

Sign once, on Ethereum

Pick the stocks and the ETH. Ferry prices the ticket from both chains and your wallet sends one transaction to Robinhood Chain's inbox. Nothing else to approve.

02 · CROSS

The bridge carries it

Robinhood's own bridge — the same one that holds everyone's ETH — turns it into a ticket on Robinhood Chain. Measured: 10 minutes at the median, 12 for nine in ten.

03 · ARRIVE

Uniswap buys, for you

The ticket runs a purchase on Uniswap with the ETH it carried, paying the shares to your address — the same address you boarded from. Gas money for Robinhood Chain arrives alongside.

04 · OR WAIT

A bad price buys nothing

Every purchase has a minimum. If the price moved past your limit on the way, nothing is bought and the ticket waits on Robinhood Chain for seven days: try again, or take the ETH.

Ethereum you sign one transaction to Inbox Robinhood Chain the ticket runs SwapRouter02 shares → you the ticket ETH + the purchase + gas money the way home sell → send → claim after 6.4 days
You never hand anything to FerryThe page builds the transaction; your wallet sends it to Robinhood's inbox. Ferry holds no key, no ETH, no shares, and there is no Ferry contract to trust.
The deposit is exactly what the ticket costsArbitrum keeps any excess at an address you cannot spend from, so Ferry never overpays: ETH to spend + the ticket's fee + its gas, to the wei.
Gas money arrives however the purchase goesThe ticket's fee cap is set high on purpose; Robinhood Chain refunds the difference to you before the purchase runs. About 0.0003 ETH — forty-odd transactions there.
The timetable

Measured on everybody's tickets, not promised.

Every ticket Robinhood's bridge carried in the 8 hours to 30 Sep 2026 — 292 of them, matched message by message from the Ethereum block that boarded it to the Robinhood Chain block that created it.

The ticket id of 24 of them was recomputed from the Ethereum side with Ferry's own code and matched Robinhood Chain's exactly — the tracker on the Cross page depends on that. Robinhood's bridge held 296,347 ETH at the time. Withdrawals: the rollup's confirmation period is 45,818 Ethereum blocks (6.36 days); the newest confirmed Robinhood Chain block was 6.44 days old.

The way home

Sell on Robinhood Chain. Claim on Ethereum.

Coming back is slower, and Ferry says so: a withdrawal from any Arbitrum chain waits out the rollup's challenge period before Ethereum pays it. Here that is 6.4 days.

Sell to ETH

Pick what to sell. One Robinhood Chain transaction sells it all through Uniswap and unwraps to ETH in your wallet, each sale with its own minimum. A signature per stock instead of approvals.

Send it home

One more transaction hands the ETH to Robinhood Chain's own withdrawal system. It leaves your wallet now and is recorded for Ethereum, addressed to you.

Claim in 6.4 days

When Ethereum has confirmed Robinhood Chain past your withdrawal, My trips shows a Claim button. Ferry builds the proof from Robinhood Chain; your wallet sends it to the outbox.

Nothing of ours in the way

Built on what was already there, and honest about it.

Robinhood's bridge

The inbox, bridge and outbox are Robinhood Chain's own Arbitrum Nitro contracts on Ethereum — the addresses Robinhood publishes, holding 296,000 ETH today. Ferry calls them exactly as their own bridge page would.

Uniswap's router

The purchase is SwapRouter02 on Robinhood Chain, where every stock's pools live. Each leg has a minimum computed from a live quote; each sale on the way home too.

Your own address

Shares, refunds and gas money all go to the address you board from. Smart-contract wallets would be re-addressed by the bridge, so Ferry refuses them rather than lose your refunds.

What can go wrong

The price can move past your limit (nothing bought; your ETH waits). The sequencer can be slow (the ticket still arrives; a purchase past its deadline buys nothing). A ticket nobody touches for seven days pays its ETH to you.

What it costs

Ethereum gas for one transaction, the bridge's own submission fee, Robinhood Chain gas for the purchase, and Uniswap's pool fees. Ferry adds nothing. Every figure is shown before you sign.

Tested against both chains

The last run: 11/11 properties and 6,206 checks passed against live state on both chains (30 Sep 2026). How it is tested.

Questions

Before you board

Do I need anything on Robinhood Chain first?

No. You board from Ethereum with ETH; the ticket carries the purchase and your gas money across. Your wallet will be asked to add Robinhood Chain only when you want to look at, sell or send what you bought.

Where do the shares go?

To the same address you boarded from, on Robinhood Chain. Ferry writes that address into the purchase itself, so nobody — including Ferry — can send them anywhere else.

What if the price moves while I'm crossing?

Each stock you buy carries a minimum: its live quote less your price limit (1.5% unless you change it). If the pool pays less when the ticket arrives, Uniswap buys nothing and the ticket waits on Robinhood Chain. My trips then offers to try again, or to take the ETH to your Robinhood Chain wallet, where you can buy at the new price.

Why can't I use a Safe or another smart wallet?

Arbitrum's bridge re-addresses refunds to contracts on Ethereum (it cannot know the contract exists on Robinhood Chain), which would put your gas money and any refund where you cannot reach it. Ferry checks your address on Ethereum and refuses to board a contract.

Why does coming back take 6.4 days?

Robinhood Chain is an optimistic rollup: Ethereum accepts its state after a challenge period in which anyone can dispute it. Withdrawals are paid only after that. It is the price of the bridge's security, and every Arbitrum chain has it.

Does Ferry take a fee?

No. You pay Ethereum gas, the bridge's submission fee, Robinhood Chain gas and Uniswap's pool fees — all shown before you sign, none of it to Ferry.
