Take back control of your identity Essi is a self-sovereign-identity (SSI) wallet built by Ajna, Inc
Take back control of your identity Essi is a self-sovereign-identity (SSI) wallet built by Ajna, Inc. It gives you one secure place to receive, manage and present verifiable credentials—without handing your personal data to central servers. Why Essi? Fingerprint-grade security. Private keys stay inside Apple’s Secure Enclave; biometrics unlock the wallet instantly. True self-custody. Only you hold the cryptographic keys that sign or share your credentials—Essi can’t see them, Ajna can’t read them, nobody can revoke them but you. Open standards. Works with W3C DIDs, Verifiable Credentials, AnonCreds and DIDComm v2 so you can connect to any compliant service or agent. Private by design. Zero-knowledge proofs let you prove facts (age ≥ 18, subscription valid, citizenship, etc.) without exposing the rest of your data. Offline-first. Generate proofs, scan QR invites and accept credential offers even with no internet; Essi syncs automatically when you’re back online. One-tap sharing. Present selective proofs in apps, Safari, or face-to-face via QR/NFC—always with explicit consent. Open-source core. Auditable codebase so security researchers and the community can verify exactly how Essi works. How it works Connect. Scan a QR or tap an NFC link to establish a DIDComm connection with a trusted issuer. Receive. Accept credentials—membership cards, permits, course certificates, KYC proofs—into your encrypted vault. Prove. When a requester asks, review the disclosure request and share just the attributes you approve. Audit. Check the built-in activity log to see every credential you issued, stored or shared.
