How to Compare Bridge Costs on zkSync
A checklist for comparing quotes, gas, destination fees, and expected received amounts.
Why this matters on zkSync
A proper fee comparison uses the final received amount rather than the headline bridge fee. Gas and price impact can materially change the result.
zkSync is an Ethereum scaling ecosystem with its own network context and token representations.
zkSync is part of the Ethereum scaling ecosystem. The same ticker can exist on Ethereum and on zkSync as separate token contracts, so a balance seen on one network cannot be assumed to exist, or to be redeemable at the same value, on the other.
zkSync: what to pay attention to
- Costs: Compare network fees with bridge and liquidity costs for the complete route.
- Security: Check the active network, contract and destination before signing.
- Assets and tokens: Verify the asset contract on zkSync before assuming it matches another network.
A zkSync checklist for this topic
- Compare the quote, the minimum received amount and the total fees before signing.
- Check that the token you hold on zkSync is supported for the route you are considering.
- Allow for a delay between sending and receiving; do not repeat a transfer while one is pending.
- Keep enough native balance on zkSync to pay for the transaction that starts the transfer.
Bridge from zkSync

The bridge guide below is informational; any transaction depends on current network conditions and the route shown in the bridge interface.
