Solidus Identity

Self-sovereign identity manager — create DIDs, manage credentials,
share verifiable claims with zero-knowledge selective disclosure.

---

Overview

Solidus Identity is the self-sovereign identity hub of the Solidus Network. Users create W3C DIDs, receive verifiable credentials (from KYC, email, phone verification), and selectively share claims with third parties — all without a central authority.

Features

• DID creation — Client-side Ed25519 key generation, did:solidus method
• Credential inbox — Receive and manage verifiable credentials
• Selective sharing — Share specific claims via QR code without revealing full credentials
• OIDC bridge — "Login with Solidus" for third-party applications
• Trust score — Reputation scoring based on credential history
• Social recovery — 3-of-5 guardian-based key recovery (planned)
• 31-page app — Full identity management interface, dark/light mode
