zkSync Era Permit Signature Checker

What Is zkSync Era?

zkSync Era is a Layer 2 scaling solution and one of the first projects to use the novel zkEVM technology. This technology offers very low fees while maintaining strong security guarantees through the use of zero-knowledge proofs. zkSync previously created zkSync Lite, which was an early version of zkRollup technology that was not yet EVM compatible. zkSync Era is the next iteration, adding full EVM support. The native token of zkSync Era is ETH. Learn more about zkSync Era on its website.

What Are Permit Signatures?

Permit Signatures are used to grant token approvals without sending a transaction. Because these signatures are not stored on the blockchain, there is no way for Revoke.cash to know if you signed them. This page lists your tokens that support offchain Permit signatures.

Only if you know that you signed a Permit signature on a scam website, you need to cancel the potential signatures on this page, otherwise you are wasting transaction fees. When you cancel potential signatures for a token, they will remain in the list but cannot be cancelled again for some time.
