list()

List userstore keys

The Xumm userstore allows you to store key/value records specific to your application and the user for which the JWT was issued. The userstore stays does not expire, meaning you can permanently store userdata and retrieve it whenever the user visits again.

The `list` method returns a Promise with an array of keys stored.

xumm.userstore.list().then(storedKey => {
  console.log(storedKey)
})
