Features

Inji Web Wallet is a browser-based, open-source digital wallet designed for secure download, verification, storage, and sharing of Verifiable Credentials (VCs). It supports OpenID4VCI, OpenID4VP, IETF SD-JWT, and W3C VC standards—no app install required.

Multiple Credential Format Support

Inji Wallet is designed for interoperability and flexibility by supporting a wide range of credential formats:

  • W3C Verifiable Credentials (JSON-LD VCs) Data Model 1.1

    • Standards-based credential format is widely adopted across ecosystems.

    • Suitable for general-purpose credential issuance and verification.

  • ISO 18013-5 (mDL)

    • Mobile Driving License and Mobile Document specification.

    • Supports use cases like identity verification in transport, law enforcement, and service access.

  • IETF SD-JWT

    • IETF SD-JWT Verifiable Credentials: Enables holders to download and share credentials in IETF SD-JWT format. This allows users to share only the necessary attributes while keeping other data private, ensuring privacy-preserving credential sharing.

    • Allows users to share only the required claims with verifiers via the OpenIDVP flow, where these selectively disclosable claims can be shared as per the user's need. (Coming Soon in the upcoming release)

This multi-format support allows Inji Wallet to work seamlessly across different ecosystems, ensuring compatibility, security, and user privacy.

Login with Any Identity Provider (IdP)

  • Supports Google and other OpenID-compliant IdPs

  • Credentials are stored securely in the browser-based wallet after login, enabling access across sessions and devices, depending on the configuration.

  • Verifiable Credentials are now stored in the “Stored Cards” section.

  • You can view and download the credential as a PDF file locally on your system, or print it out once downloaded.

  • You can reset your passcode if you forget it during login. However, the option to change the passcode after logging in is currently not available.

Guest Mode (No Login Required)

  • Ideal for privacy-sensitive or public campaigns

  • Credentials are downloaded directly to the local device (not stored in the wallet)

Credential Download Options

  • OpenID for VC Issuance: Interoperable with trusted issuers

  • Example Issuers:

    • Republic of Veridonia National ID Department - National ID

    • StayProtected Insurance - Insurance Credentials

    • Republic of Veridonia Tax Department - Tax ID

    • AgroVeritas Property & Land Registry - Land Record

Verifying Credential Authenticity

  • Inji Web Wallet uses robust cryptography to verify that the VC is:

    • Digitally signed by a trusted issuer.

    • Cryptographically valid based on proof type.

    • In addition to traditional VC formats like JSON-LD, Inji Web now supports Multiple Credential Format Support. Inji Web Wallet is designed for interoperability and flexibility by supporting a wide range of credential formats:

      • W3C Verifiable Credentials (JSON-LD VCs) Data Model 1.1

        • Standards-based credential format is widely adopted across ecosystems.

        • Suitable for general-purpose credential issuance and verification.
