Lol fuck dude, what timing. I just reached the end of my rope trying to get nostr-tools and NDK to play nicely together for nip57.
nostrify here I come! this looks incredible.
Here, you inspired me to rework my zaps implementation and add a doc for it: https://nostrify.dev/zaps

the big question... will this take my existing NDK signer, or would I need to rip all that out...?
Have NDK generate the zap request event however it does it, then you can pass it directly into lnurl.getInvoice​.
Basically you can use this LNURL module with any other library or framework.
