The key transferring login functionality is one thing I like about nostr, the issue is mainly just in this experimental stage I haven't found a good way to set up tipping, even after setting up a few login keys to try different methods

It is a bit fiddly There is a way to set up 'one tap zaps', I did it with get alby, think you can look up 'nwc' 'new wallet connect'. You can also have Zeus wallet as an android app connected to your ge alby. And if I'm reading it right nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5 are right now in the very process of rolling out some sort of even easier way without having to use alby (?) Perhaps. You might have more luck understanding it than me :)
