A built in wallet just like primal but not kyc ….
That should be the standard on all Nostr apps imo
But right now it doesn’t exist yet as far bc as I’m aware?? Idk 🤷
If you use the Breez SDK, you can do this, I did this with Agora. But technically it's not perfect because Breez could ban the app API key. Though users could take their seed words elsewhere and get their funds.
