HODLXXI is a Bitcoin-native Auth0: sign-in with keys, not accounts.
OAuth2/OIDC for apps, LNURL-Auth for wallets, Nostr for social identity, and Proof-of-Funds for trust gating.
Keys replace accounts. You authenticate by proving control of a key — not by handing over email + password.
Developers get standards: OAuth2/OIDC for Web2/Web3 apps, sessions, scopes, and redirects.
Users get native flows: Bitcoin signatures, LNURL-Auth QR, Nostr extensions, and optional Proof-of-Funds signals.
Presence is a signal (who is online / ready to coordinate), not a harvested social graph.
Covenant descriptors extend identity into time: reciprocal commitments with observable rules.
