Metis Permit Signature Checker

What Is Metis?

Metis is a Layer 2 scaling solution for Ethereum. It was originally a fork of Optimism, but has moved in its own direction since its creation in 2021. Metis provides support for creating multiple interconnected chains in support of creating Decentralized Autonomous Companies (DACs). While Metis is an EVM-compatible Layer 2 chain, it does use its own native token to pay for gas fees on the L2. The native token of Metis is METIS. Learn more about Metis 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.
