Initialize

import { Web3User } from "@nexeraid/web-onboarding-sdk";

Generate a new Private Key

const userProvider = await web3User.connect(jwtToken, verifierIdField, domain);

export type TypedDataInput = {
  domain: any,

  types: { SponsoredCallERC2771: any }
}

const signature = await web3User.sign(msg);
