Honestly, we probably shouldn’t even be calling these zaps… there is no lightning involved, right? These should have a nut-related name and clients should probably indicate which mint the nuts are from for the exact reason you point out.

Yeah i don’t think they should be called zaps. Thats confusing af, it is completely different.
To me it does beg the question if nip57 could use more generic naming. It seems like zaps and whatever we want to call this could follow a similar data flow over nostr and there might not be a point in having separate nips. Effectively zaps would just be the lightning implementation of nip57
