Zeus wallet nostr:nprofile1qqsrf5h4ya83jk8u6t9jgc76h6kalz3plp9vusjpm2ygqgalqhxgp9g84ctjf is working but it's kinda overkill and weird UX simply for receiving zaps on Nostr; and there's no NWC yet (https://github.com/ZeusLN/zeus/issues/2180) so sending is even higher friction.
I should have led with: it's a very impressive non-custodial LN mobile wallet/node! But its not the right choice for Nostr yet. I'll leave my sats in it for now and hope they add more Nostr integrations soon!
