Is there a chance for Passport to get support for new Silent Payment address in near future, maybe with Envoy wallet?
Right now Silent Payment is a buzz feature among wallets developers including those who work for Foundation which is already committed to implement it, eventually, first in Envoy app then in Passport device. Looks like you forgot about this post made a few weeks ago:
What we will eventually add in, however, is Silent Payments (BIP 352). First with Envoy, and then with Passport somewhere down the line.
