I imagine so, however I am not specifically aware of any such information.

I barely have my own personal relay set up and so far the only NOSTR client it even works with is Damus which does not have zaps.

I am using Damus as my NOSTR notification client. I have a few other clients I use for scrolling, posting, and zapping.

It’s all a giant Frankenstein right now.

If you dig into that relay issue and you find anything, please share.
