I see that. But wallets are not part of what we call nostr. Though we can use wallets with it. That is to say, wallets and nostr work well together, but they are seperate things. Credit cards and Amazon work together, but http doesn't issue you a credit card. And that credit card can be used not only through http, but also at the local coffee shop. And unlike credit cards, crypto is hard to deal with, but that's not a nostr problem, it's a crypto (and government) problem. I understand instant this and that, but nostr apps do facilate all that, even payments by hooking into wallets. But the wallet itself is not an issue for nostr to solve. That all Said, some apps do handle a lot of that, like fountain. I hear fountain is a great way to get started in crypto.
