Security at
the core
Every asset that moves between Ethereum and Robinhood Chain moves over the canonical Arbitrum bridge. There is no guardian set, no multisig and no third-party validator — the security of a transfer is the security of Ethereum itself.
Battle-tested contracts
The canonical bridge contracts are public and have secured Arbitrum rollups since 2021. Robinhood Chain inherits them rather than shipping a validator set of its own.

No third-party validators
There is no separate validator set to bribe, coerce or compromise. Messages are validated by Ethereum's own contracts, and the only thing between a withdrawal and the L1 is the challenge period.
Always open source
Everything this page claims can be checked without taking our word for it. Bridge state, token supply, fee history and every message are public on Blockscout, and the chain is a standard Arbitrum Orbit deployment.

Withdrawals
Leaving Robinhood Chain takes two steps: the message is posted to Ethereum, then it waits out the challenge period — about seven days — before the L1 will execute it. That delay is what makes the exit safe, and it is enforced by Ethereum, not by us.
Deposits
Deposits monitors asset outflows on connected chains, limiting volume to an acceptable ceiling. This slows potential cross-chain contagion during existential smart contract or blockchain vulnerabilities, enhancing security.

Robinhood Chain Blockscout
Bridge state, token supply, fee history and every transaction are public. Nothing on this page has to be taken on faith.
The challenge period
A withdrawal is final only once Ethereum's Outbox contract accepts it. No key — ours, Robinhood's, or anyone else's — can move funds out early.
Bug bounty program
Found something wrong? Report it to the Robinhood Chain team. The contracts and the chain are public, and so is the place to file issues.
