Yeah, I think it’s confusing because nostr:npub1kvaln6tm0re4d99q9e4ma788wpvnw0jzkz595cljtfgwhldd75xsj9tkzv is both a mint and an app. nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5 supports NWC and ecash but it doesn’t generate its own NWC strings. You have to get those from other sources.
