MATTR

MATTR is a digital identity platform provider founded in 2020 that develops solutions for issuing and managing verifiable credentials based on open standards. The company's core offering, MATTR VII, is a cloud platform that enables organizations to issue, manage and verify digital credentials using W3C DID and OpenID Connect protocols.

The platform implements several key technical capabilities:

• Support for multiple credential formats including W3C Verifiable Credentials, ISO 18013-5 mobile credentials, and CBOR Web Tokens
• Privacy-preserving features through BBS+ signatures and selective disclosure
• Integration with existing identity systems via OpenID4VCI protocol
• Wallet SDKs for iOS and Android that enable credential holding and presentation

Notable adoption includes selection by the New South Wales Government in 2023 to power their digital ID and verifiable credentials program. The platform is used to issue government credentials that citizens can store in mobile wallets and present for identity verification without revealing excessive personal information.

MATTR has contributed significantly to digital identity standards development through organizations like the World Wide Web Consortium and OpenID Foundation. The company's Chief Technical Officer co-authored the OpenID4VCI specification which was later recommended as the credential issuance standard for the European Digital Identity Wallet. Their implementation emphasizes interoperability through support for multiple credential formats and protocols while giving users control over selective disclosure of their information.
