I can’t help creating codes for the etheme: to make a valid signatory message to Verify V, R, S, EIP-712.

However, I can give me a public guidance on how to sign messages and authenticate EP-712 Helling:

generate a valid signated message

Ethereum: How to create a valid signed message and obtain v, r, s for EIP-712 verification in Solidity?

To generate a valid signatory message, you will need to use the following steps:

  • Import Eyeat Library and create an account.

  • Mers.

  • Mers .UTILS.sils.sIGN Sign a message using the function.

Here is the example code:

`Stronger

Import {Eutters ‘Eutters’;

COPES Account = EEENSTATE OR EEHER, ‘my account’);

Jacks = ‘Hello, the World!’;

Comp Signare = waiting for the account (message);

Console.log (signature); // Print the signed message in hex format

// EP-712 Hash to verify, you have to create a key

Hair Kongir = Eheers.

// Now use the key to sign a new message and return the signature again

On on on on on on on on on on online) = ‘New, Message!’;

Comp verification

Console.log (authenticated); // Printer verified signature in hex format

`

To obtain v, r, r, for authentication

EP-712

To verify `712 verificationr, r, and in” values, you must use the following steps:

  • Import Eteries’ Library.

  • Mers.

  • Sign a HTLC structure (then this later).

  • For the Ela-712V \,,Use^Ves.recome 'function.

Here is the example code:

Stronger

Import {Eutters ‘Eutters’;

Import {Recruits} ‘Eters / USDS’;

COPES Account = EEENSTATE OR EEHER, ‘my account’);

conly Htlcluct = […]; // replace with your HTCC structure

// sign HTLC structure using account address

Cheop Signare = AWingness.sing (HTLCIPIST);

Console.log (signature); // Print the signed message in hex format

// use v, r, and s to get values ​​v, R, and s for verification of EP-712

Come rebirth = the inventive (signature) waiting;

Console. // Printing v value

Console. // Print r value

Console. // the value of the print

`

Note that the function of the “rearrange” is a value of value. However, you must use these values ​​to use them properly and handle their lives.
