Worth reading up about it. But if you "zap" my show (it's not called that), then the zap goes to 49% me, 49% my co-host, 1% the podcast index, and 1% fountain (who do comments and help promote it). I'm 100% in charge of that split.
It gets more exciting when you use wallet-switching tech to support a music artist I play in my show, so "zaps" during that song are split further to the artists I'm playing.
