Follow a Video

const { createWallet } = require('@affinidi/wallet-node-sdk')
const walletFactory = createWallet('AffinityCore')

Lets setup wallets

const accessApiKey = '<yourkey>'

const options = {
    env: 'prod',
    accessApiKey:accessApiKey,
}
  const issuerWallet = await walletFactory.createWallet(options, 'P@55word!!!')
  const holderWallet = await walletFactory.createWallet(options, 'P@55word!!!')

Setup credential

const jsonSchema = 'https://schema.affinidi.com/ContentLikeV1-0.json'
