I think it works already. I'm using it.
Are there plans to add NIP-57 (zaps) support to npub.cash? I zapped this note and it sent from my wallet but doesn't show on the note. Tagging nostr:npub12rv5lskctqxxs2c8rf2zlzc7xx3qpvzs3w4etgemauy9thegr43sf485vg because I don't remember who runs npub.cash. nostr:note1cgd4e0gze7d959q030hzkl94lrg7ms23z6vmm564k05t7f52hhnq5qmtdk

Hmm ok yea I just checked in nostr.band and I see the zaps on the note, including mine. But Damus doesn't show any, and even my zap that I sent showed briefly as pending in Damus and then disappeared. Maybe nostr:npub1zafcms4xya5ap9zr7xxr0jlrtrattwlesytn2s42030lzu0dwlzqpd26k5 knows if there's an existing issue with some zaps not showing in Damus.
