ethers-signux

Realize new UX with signing and validating by ethers.js

ethers.js is the popular web3 library of javascript that can make signature and verify it. However, it's complex to use it because it have many funcitons and there are little documents.

ethers-signux makes you easy to sign and verify with ethers.js.

Usage ℹ️

For example, AWS Lambda function.

sign

const ethers = require("ethers");
const sigEthers = require("@yamapyblack/ethers-signux");

exports.handler = async (event) => {
    const privateKey = "......" // set private key
    const types = ["address"];
    const values = ["0x12fA9a179f1db2a97052CcbFD7a4AAAA91Fef780"];

    const signer = new ethers.Wallet(privateKey)
    
    const signature = await sigEthers.signMessageParameters(signer, types, values)
    return signature
};

validate

const ethers = require("ethers");
const sigEthers = require("@yamapyblack/ethers-signux");

exports.handler = async (event) => {
    const signature = "..."; // set signature string
    const types = ["address"];
    const values = ["0x12fA9a179f1db2a97052CcbFD7a4AAAA91Fef780"];
    
    const signerAddress = sigEthers.recoverParameters(types, values, signature)

    return signerAddress
};

That's all.
