Bridge from Ethereum to Optimism
Use StarBridge to check available cross-chain routes between Ethereum and Optimism. The live bridge interface determines which assets and routes are currently available.
CROSS-CHAIN BRIDGE
Ethereum to Optimism bridge.
Review the current route for moving supported digital assets from Ethereum to Optimism. Availability, fees, liquidity and execution estimates can change with network conditions.
Go to the bridge ↓Check the live route
Before approving a transaction, review the source network, destination network, asset, estimated output, network costs and route details shown in the live quote.
Non-custodial wallet flow
StarBridge provides an interface for connecting your wallet and reviewing a route. You approve transactions from your own wallet rather than depositing funds into a StarBridge custodial account.
Fees and completion time
Cross-chain costs can include source-network gas, destination execution costs and route or liquidity-provider fees. Estimated completion time depends on the selected route and current blockchain conditions.
About Ethereum
Ethereum is the largest smart-contract network and the settlement layer for many Ethereum layer-2 networks.
About Optimism
OP Mainnet (Optimism) is an Ethereum layer-2 network and the origin of the OP Stack that other layer-2 networks, including Base, build on.
Gas you will need
Both Ethereum and Optimism use ETH for network fees, so the same asset can cover gas on each side. Keep a small balance of ETH on Ethereum for the transaction and on Optimism for whatever you do after arriving.
Moving into a layer-2
Optimism is an Ethereum layer-2 network, so transactions there are usually cheaper than on Ethereum mainnet. Compare the total cost of the route, including the source-network gas on Ethereum, before you confirm.
