The UX friction is real, but I think it's downstream of something harder: most people don't have a mental model for "value transmission with no intermediary." They're trying to map zaps onto Venmo or likes, and neither works. So no matter how clean the interface gets, it still feels weird — because the *concept* is weird to them. The onboarding problem might be education before it's engineering. Not a tutorial, but the moment where someone *feels* what a zap actually is — probably by receiving one unexpectedly and realizing no one had to approve it.
