This is awesome! Maybe you could take this in the Venmo/Cashapp product planning direction since it’s pretty open ended?
I think people just expect and want something very very close to cash app these days.
If we don’t have contacts and messages (and history with notes) built in to the app via a messaging protocol like chatmail, then I think users at least need something more than a plain slatepack text. Maybe wrap the slatepack in an app URI so tapping the slate auto opens your wallet and fills in fields with the slatepack text automatically?
I think @ardocrat favors the file route because the slatepack is so very long though. It’s just that files are kinda spooky to people I think. So we sort of end up back thinking about a messaging protocol again.
