Verifiable Credential Presentation (OpenID4VP)

Overview

Inji Web Wallet supports Verifiable Credential (VC) Presentation using the OpenID4VP standard. This allows users to securely share their JSON-LD Verifiable Credentials directly with a verifier through a live, interactive, verifier-initiated flow.

Using this feature, Inji Web can receive a presentation request from a verifier, prompt the user for trust and consent, select matching credentials from the wallet, and send a cryptographically signed Verifiable Presentation (VP) back to the verifier.

This enables real-time, standards-compliant, privacy-respecting credential sharing without needing to upload PDF files or scan QR codes manually. This feature's page explains the entire capability in a clear, functional, end-to-end way.

Why This Feature Matters

  • Secure by Design: Uses OpenID4VP for end-to-end, signed presentations.

  • User Controlled: Users explicitly trust the verifier, choose which credentials to share, and consent before sharing.

  • Interoperable: Works with any OpenID4VP-compliant verifier.

  • Paperless & Instant: No need for scanning, printing, or uploading PDFs.

  • Future Scalable: Forms the foundation for SD-JWT selective disclosure (coming soon).

Supported Credential Types

Currently supported:

  • W3C JSON-LD Verifiable Credentials (VC Data Model 1.1) ✔ Supported for full OpenID4VP presentation flow

Coming Soon:

  • IETF SD-JWT (Selective disclosure via OpenID4VP)

  • ISO 18013-5 mDL / mDoc

How does the OpenID4VP Flow Work?

A functional walkthrough of the complete user journey:

User Flow (Step-by-Step)

  1. Verifier initiates a presentation request (via redirect_uri ).

  2. Inji Web Wallet opens and shows a trust screen with the verifier identity.

  3. User approves trust (“Yes, proceed”) or declines (“No, cancel request”).

  4. The web wallet displays requested credentials and allows the user to select which to share.

  5. User gives consent (“I Consent & Share”).

  6. Wallet prepares and signs a Verifiable Presentation.

  7. Presentation is sent to the verifier via the OpenID4VP protocol.

  8. User sees a success screen and is automatically redirected back to the verifier.

Current Limitations

  • Inji Verify does not yet support initiating OpenID4VP (coming in a future release).

  • Only JSON-LD credentials are supported today.

  • SD-JWT selective disclosure is not yet supported(coming in a future release).

Important: In the current release of Inji Web Wallet 0.15.0 version, only the mock verifier services can generate OpenID4VP requests.
