dappauth.js is a tool that can verify EOA signature and smart contract signature (ERC1271).
Usage
const Web3 = require('web3');
const DappAuth = require('@blocto/dappauth');
const dappAuth = new DappAuth(new Web3.providers.HttpProvider('http://localhost:8545'));
async function debug() {
const challenge = 'foo';
const signature =
'0x49b5e108d0b7ce795125acbc08b331aad170e4afe8daa5b4b484d12b9253316c4ca0cb36cec51682bcc9a65d6cb28002bd4835845d8f1de21afafe1132eaed3d1b28171e3bf436f2301c0bd657501cafb2a9344efe042495adba2852858db559da2fb4280007de4d631b9357493a979c4024927aec580ef3a22603918eb3b3071b1c';
const address = '0x86aa354fc865925f945b803ceae0b3f9d856b269';
try {
const isAuthorizedSigner = await dappAuth.isAuthorizedSigner(
challenge,
signature,
address,
);
console.log(isAuthorizedSigner); // true
} catch (e) {
console.log(e);
}
