The only thing I found was on GitHub about the Nips, a list in .md, nostr-tools, and the SDK. It's a bit overwhelming. I've already managed to integrate NIP-07, 09, 15, 46 and a few others I don't remember. I haven't got there yet, but my question is how LN is implemented to manage payments. But idk what to use, NWC, LN, cashu? I'm lost here🥶
