In this article, we will explore how to send an EIP-712 Message Sure using the API kit in the Ethereum Block Chain.
What is EIP-712?
EIP-712 is a specification for digital signatures that allows safe communication between the parties. It uses a combination of cryptographic hash functions and a hash KECCAK-256 to create a unique identifier for each intelligent contract or contract.
Use of apitik to send a message EIP-712
Apitik is a popular Library used to interact with the Ethereum Block Chain. This is how you can send an EIP-712 Message Using Apitik:
`Javascript
Const name = deb alea.
Const = 1 Version;
Const Nance = "0";
// Create a New EIP-712 Message
Const msg = {
Type: 'EIP-712 V4',
Worth: {
Type: 'Digest',
Hash: Sha256 (Name, Version, Nance),
},
};
// Send the Message To Safe
Consta SafeAddress = '0x ...'; // Replace with the direction of the Safe Contract
SafaDdress.call (msg);
