Full description

MATTR Go Hold is a versatile tool designed to work with the MATTR VII platform and other digital trust service providers. It enables users to securely collect, store, and present verifiable digital credentials. Built using the MATTR Pi Wallet Toolkit, this app showcases all of the capabilities offered by MATTR’s digital wallet infrastructure, providing users with a practical demonstration of how digital credentials can be managed and shared. Key Features - Credential collection and presentation: Users can collect credentials from issuers and present them to verifiers via QR codes or deeplinks. - Biometric authentication: Access the wallet using facial recognition or fingerprint for enhanced security. - Selective disclosure: Share only relevant information with verifiers, preserving privacy during interactions. - Interoperability and flexibility: The Wallet supports various credential profiles, including Mobile (mDLs and other mdoc derivatives) and Compact (COSE-based). - Multi-protocol support: The wallet supports OpenID4VCI and VP Request protocols for credential issuance and presentation. - Notifications: Enable push notifications for real-time updates, such as new credential availability or verification requests. - Custom-branded credentials: Issuers can customize the appearance of credentials with logos, colors, and watermarks for brand consistency. Functionality - Scan, tap, or click to present credentials: Quickly share credentials with a QR code or deeplink, simplifying the verification process. - High-assurance authentication: Use cryptographic methods to ensure the security and integrity of verifiable presentations. - Activity log: Keep track of all credential interactions with issuers and verifiers through a dedicated activity tab. - Trusted interactions: The app validates issuers and verifiers, displaying a verification tick for confirmed sources. MATTR GO Hold is ideal for organizations looking to explore MATTR’s credential lifecycle capabilities and see firsthand how verifiable credentials can be managed securely within a privacy-preserving environment

What's new

We’re deprecating support for collecting, holding, and sharing JSON-LD credentials. You’ll still be able to view any existing JSON-LD credentials in your wallet, but you won’t be able to claim new ones or respond to presentation requests using them.
