Finally figure out a non-custodial zap setup:

1) voltage node running lnbits

2) vida account associated to custom nip-05 id

3) connect vida account to an lnbits wallet via their integration page

4) paste the @vida.live into your nostr account for the lnurl address

5) zap away

I’m sure someone better at lnbits & it’s extensions knows how to skip Vida altogether, but this at least worked for me. The node and lnbits could also be self-hosted of course. This is very much a “good enough” solution to me.
