Overview

A common component of any digital trust infrastructure is a user's digital wallet. The root of trust in a decentralised identity ecosystem primarily comes from issuers which are authorities on a set of information. Issuers provide users with credentials that contain authoritative information about them in the form of digitally verifiable claims.

The wallet allows an end user to store and manage verifiable credentials that have been issued to them, so they can later be used for authentication and access purposes. By giving the user control of their own digital wallet, a user is fully in charge of how and when they choose to present information to a verifier or relying party. When a verifier needs to validate some information, they can request specific pieces of data from the holder to meet their verification requirements.

The wallet handles the logic for you and puts the user in charge of who gets access to their data and what data is shared. The MATTR Showcase Wallet app makes use of the powerful computing hardware found in smartphones and packages the wallet to the user as a downloadable application.
