What to Check Before Using a Crypto Bridge on zkSync
Questions to ask about the route, token, destination chain, fees, and transaction details.
Why this matters on zkSync
The most important bridge question is not 'does it work?' but 'what exactly will happen if I sign?' Read the route, source and destination assets, fees and recipient before approving.
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
- Confirm both the source and destination network, including whether zkSync is one of them.
- 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.

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