Bridge to Robinhood Chain

The canonical Arbitrum bridge. A deposit is a message to Ethereum's own inbox contract and a withdrawal is proven against Ethereum's outbox — there is no guardian set, no multisig and no third-party validator in the path.

What actually happens

Deposit

Your transaction calls depositEth() on the Delayed Inbox on Ethereum, or the token bridge's outboundTransfer after an approval. The deposit is retried on Robinhood Chain and usually lands in about ten minutes. If the L2 leg fails on gas, the funds are not lost — the ticket can be redeemed manually for seven days.

Withdraw

You send on Robinhood Chain and the message is written into Ethereum's Outbox after the seven-day challenge period. The final claim is an L1 transaction (it costs L1 gas) — the official Arbitrum bridge does that step for you, and this page links you there with your transaction hash.

Why it is trustless

Both directions are enforced by contracts on Ethereum. Nobody signs off on your transfer: a deposit is final because the L1 contract said so, and a withdrawal is claimable because Ethereum can verify it. There is a validator set for the chain, but not for your money.

Contracts this page uses

Contract	Chain	Address

Everything above is read live from the chain at the moment you press the button — the gateway, the L2 token address and the submission fee are all resolved on-chain, so a mis-typed token cannot quietly go somewhere else. Prefer a UI? The official bridge at bridge.arbitrum.io is the same route with the claim step included.

Claim a withdrawal on Ethereum

A withdrawal is two steps. Your Robinhood Chain transaction locks the funds and writes the message; after the challenge period Ethereum's Outbox will accept a Merkle proof for it. Paste the transaction hash below — this page builds the proof from the chain and sends the claim. Nothing to trust here: the proof either verifies against the root Ethereum already stored, or the transaction reverts.

Faster routes

The canonical bridge is the trustless default, but it is not the only way — and for small amounts the wait is the real cost. These are the routes Robinhood Chain's own documentation lists; each is a different trust model, and none of them is operated by us.

Route	Type	Speed
Arbitrum canonical bridge	Trustless L1↔L2	~10 min in · ~6.4 days out	open
Relay	Intents — a solver fronts the money	seconds	open
Across	Intents — capital-efficient	seconds	open
Stargate	LayerZero OFT (WBTC, USDG, …)	minutes	open
Transporter	Chainlink CCIP	minutes	open

⚠️ An intents bridge is not the canonical bridge: you are trusting a solver to pay you on the other side. That is why it is fast. For large amounts, or when you care about the trust model, take the canonical route and wait.
