Optimism Cross-Chain in three steps
Move from intent to signed transaction without creating an account, handing funds to a custodian or guessing what the route will do.
Connect your wallet
Open the app and connect your wallet for the OP Mainnet ecosystem. You keep control of keys and approvals.
Pick chain and asset
Choose Ethereum, Optimism or another supported EVM route, then select ETH, OP or the asset you want to move.
Review and sign
Check the swap path, bridge route, network fee and estimated arrival window, then approve only from your wallet.
Built for Optimism routes that stay in your hands
Self-custody first
The app prepares the transaction; your wallet decides. Funds are not parked in an account while you wait.
Layer-two coverage
Route across Ethereum layer two networks and supported EVM chains from one familiar flow.
Transparent route checks
Compare route behavior with live app data, then use public references like rollup network data for extra context.
Optimism Cross-Chain questions
01What is Optimism Cross-Chain?
It is a non-custodial DeFi app for cross-chain swaps and bridge routes involving Optimism. You choose the asset, review the route and sign from your wallet.
02Which chains and assets can I use?
The app is built for OP Mainnet, Ethereum and supported EVM routes, with assets such as ETH, OP and eligible ERC-20 tokens. See the full list on the supported chains page.
03How long does an Optimism cross-chain transfer take?
Timing depends on the route, source network, destination network and required confirmations. The app shows the current estimate before you approve.
04What does it cost?
Costs depend on network gas and the selected route. Review the live quote in the app and compare it with context from the Ethereum gas market before signing.
05Is this safer than sending funds manually?
It reduces manual chain and asset selection errors by presenting the path before confirmation, but every on-chain transaction still carries risk. Verify the wallet prompt, asset, network and recipient details.
