StarBridge

Bridge from zkSync to Ethereum

Use StarBridge to check available cross-chain routes between zkSync and Ethereum. The live bridge interface determines which assets and routes are currently available.

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 zkSync

zkSync Era is an Ethereum layer-2 network that uses zero-knowledge rollup technology.

About Ethereum

Ethereum is the largest smart-contract network and the settlement layer for many Ethereum layer-2 networks.

Gas you will need

Both zkSync and Ethereum use ETH for network fees, so the same asset can cover gas on each side. Keep a small balance of ETH on zkSync for the transaction and on Ethereum for whatever you do after arriving.
