Do they charge a little for zapping? I mean it might be a good idea to try to find ways to substain the project. Fountain charges you a little bit when boosting or commenting, and I'm fine.
They do not charge. But I don't see why zap splits couldn't be added for funding in the future in a similar method to Damus doing this before Apple made them remove Zaps.
FYI Someone was kind enough to share a script recently that restores zaps on Damus. Worked like a charm 💪🏽 I’ll look for it if you need it
how is primal getting away with zaps on ios?
Integrated Lightning wallet and proper licensing.
