import { createSignaturePayloadB64 } from 'covalent-js-sign';

// To create the payload to that include the challenge data and the signature in base64,

const privateKey = "59e96b740f0af54f2d4335ddd033816fa24348b4097d3fddad4f6edc939f52e9";
const walletAddress = "0x71d094E5382CA33B25B92d3A75d5C6f269A78fAe";
const chainId = "1"; // default is "1"

// Node.JS
const payload = createSignaturePayloadB64(privateKey, walletAddress, chainId);


// browser
const payload = covalent.createSignaturePayloadB64(privateKey, walletAddress, chainId);
