Wallet agnostic, I just send an android intent.
From my tests it works with monfluo and cake, stack duo doesnt work and other wallets I haven't tried
Will it use a specific wallet, or be wallet agnostic? What's that workflow look like?
I had asked the monfluo https://codeberg.org/acx/monfluo dev if he would be interested in implementing an API allowing for a signing request to be sent, he said no but almost all the work needed for that behind the scenes is the same as for qr code based transaction signing which is planned.
