I don’t think Phoenix supports a static/reusable LNURL the way WoS/Alby did, because it requires running more than just a node. However I do know that nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5 worked some magic to make this possible, so if you’re looking for a self-custodial zap-receive-address, give Zeus a shot
