Frequently Asked Questions
How do I bridge from Starknet to zkSync?
Choose Starknet as the source and zkSync as the destination in a bridge or route aggregator, pick the token and amount, review the quote and the minimum received amount, then confirm in your wallet. Keep some Starknet native token to pay the fee.
