Bridging
Robinhood Chain is reached through a canonical bridge to Ethereum, plus several faster third-party routes. This page lays out what each one is for, and what it costs you in time and trust.
This page does not move funds, and it is not a bridge. It is a reference: it names the routes that Robinhood Chain actually has, and links to each one. Bridging happens on those sites, not here. We are not affiliated with any of them.
Routes
| Route | Type | Speed | Best for |
|---|---|---|---|
| Arbitrum canonical bridge ★ | Trustless | Deposit ~10 min · Withdrawal ~7 days | Moving ETH and ERC-20s between Ethereum and Robinhood Chain. |
| LayerZero OFT / Stargate | Messaging + Omnichain token (OFT) | Minutes | Fast token movement across chains — WBTC, USDG and other OFTs. |
| Chainlink CCIP / Transporter | Messaging + token transfer | Minutes | Fast, secure cross-chain transfers and applications: move tokens and send messages — bridging SyrupUSDG and depositing it into a lending market, for example. |
| Relay | Intents-based bridge | Seconds | Fast, low-cost transfers — and bridge-and-execute, triggering an action on the destination chain in the same step. |
| Across | Intents-based bridge | Seconds | Fast, capital-efficient asset bridging across chains. |
| LiFi / 0x | Cross-chain swap aggregators | Seconds–minutes | Swap and bridge in one step. |
★ The canonical bridge is the default. Everything else is a faster route with a different trust model — pick deliberately rather than by whichever link you saw first.
The canonical bridge
It is the native bridge for this chain. It needs no third-party validators — security is inherited directly from Ethereum.
Depositing — Ethereum → Robinhood Chain
Deposits typically confirm within 10 minutes. It bridges ETH and ERC-20 tokens. Start at the Arbitrum canonical bridge.
Deposits use Arbitrum's retryable ticket system. If the Robinhood Chain leg fails — insufficient gas, for instance — the funds are not lost: the deposit can be redeemed manually from the bridge interface within seven days.
Withdrawing — Robinhood Chain → Ethereum
Withdrawing is a three-step process, and the last step has to be sent by you, on Ethereum, at Ethereum gas prices.
- Initiate the withdrawal on Robinhood Chain itself.
- Wait out the seven-day challenge period — a standard requirement of Arbitrum's fraud proof system.
- Claim the funds by submitting a transaction on Ethereum.
That third step is not a formality: nothing arrives on Ethereum until you send it, and it costs Ethereum gas. An unclaimed withdrawal is not lost — but it is also not money in your wallet yet.
For developers
To bridge programmatically, interact with the Delayed Inbox contract on Ethereum. Contract addresses are on the protocol contracts page of the chain documentation.
A bridged ERC-20 does not keep its address.
Its contract address on Robinhood Chain differs from its address on Ethereum. Resolve the
Robinhood Chain side by calling calculateL2TokenAddress on the L2 Gateway Router,
or by looking it up in the protocol contracts list. Hardcoding the Ethereum address works until it
silently does not.
Where this came from
Every route above is from Robinhood's own Robinhood Chain documentation (docs.robinhood.com/chain/bridging), captured 2026-10-01 and re-checked 2026-10-02 — the captured copy is byte-for-byte identical to what the page served then. If a route changes upstream, this page is wrong until it is rebuilt; the source page is always the authority.
