Implementing the EIP-712 Standard

Просмотров 3,3 тыс.Год назад

The EIP-712 standard allows you to present easy-to-understand content in MetaMask to users and ensure that the data was signed by the user. It is a procedure for hashing and signing of typed structured data as opposed to just raw bytestrings. In this video, I’ll walk you through the code, deploying a contract, and sending the transaction with the EIP-712. EPISODE LINKS: Code Repo: github.com/je...
