Super.
However in looking at all the browser or Papp sdks there does not seem to be any mechanism to be given access to use an accounts private key, needed for sending and other activities, without it being clear text exposed to a 3rd party vendors code.
I was hoping that the browser would have a secured data storage that a payment request could be made using and that would require user authentication/approval to use. Or a API for payment that used an account name to lookup in the app wallet requiring confirmation before sending.
This seems risky for a user to trust unknown,unverified code off the web with inputting a private key to send funds.
