Oasis Sapphire Permit Signature Checker

What Is Oasis Sapphire?

Oasis Sapphire is an EVM-compatible Oasis ParaTime network, similar to Oasis Emerald. Like Oasis Emerald, Oasis Sapphire is built to offer low fees and high throughput. But it expands this by adding support for confidential smart contracts, which is something that it takes from the non-EVM Oasis Cipher network. The native token of Oasis Sapphire is ROSE.

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.
