Frequently Asked Questions
How do I bridge from Optimism to zkSync?
Choose Optimism 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 Optimism native token to pay the fee.
How much does it cost to bridge Optimism to zkSync?
The cost combines the Optimism network fee, the route or bridge fee and any price impact. It changes with network conditions, so use the live quote and compare the final received amount, not just the headline fee.
Is bridging Optimism to zkSync safe?
Bridges add risk beyond a normal transfer. Use a trusted interface, verify the destination network and recipient address, start with a small test amount for new routes and never share a seed phrase.
