StarBridge

Bridge from zkSync to Arbitrum

Use StarBridge to check available cross-chain routes between zkSync and Arbitrum. 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 Arbitrum

Arbitrum is an Ethereum layer-2 network that batches transactions with optimistic rollup technology and settles them on Ethereum.

Gas you will need

Both zkSync and Arbitrum 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 Arbitrum for whatever you do after arriving.
