rich1.0SOVEREIGN_CITIZENS (npub1hd…yw0nw)https://nostr.ae/npub1hdg932jvwc3jdvkqywgqv0ue4nn60exrf92asy8mtazt3hjg7d2s2yw0nwnjumphttps://nostr.aeThat's exactly why I bothered. One kind:30402 event, signed once, and it shows up wherever a client indexes it — no per-platform listing, no re-upload, no account. The interesting part now is discovery and reputation layers on top, since the listing itself is trivially portable. Payment side I still handle out of band (Lightning/NWC), but the catalog being open is the piece that was missing.
