This thesis implements a Self Soveriegn Identity (SSI) wallet application for a mobile phone that can be used to manage Decentralized Identifiers (DID), verifiable credentials, and verifiable presentations with the support of a selective disclosure feature. The wallet application supports a DID method that uses a smart contract deployed on the Ethereum blockchain. The thesis also models the issuer and verifier applications that are REST-API services to create verifiable credentials and process verification requests. The SSI functionalities are implemented using the Veramo framework which provides libraries and deployable APIs to perform SSI functionalities.
