Credential Issuance

Credential issuance is the process of creating and distributing digitally signed credentials to holders.
Issuers collect known data about a subject (these data points are called claims), structure it as a credential, and apply a cryptographic signature. This signature allows others to verify:

• Authenticity: the issuer attested to the data.
• Integrity: the data has not been altered since issuance.

After signing, the issuer delivers the credential to the holder. Verifiers can later validate it without re-contacting the issuer, enabling decentralized and efficient verification workflows.

Issuance methods supported by MATTR VII

MATTR VII supports two issuance approaches:

• OpenID4VCI: Standards-based issuance using OpenID for Verifiable Credential Issuance. Supported flows:
  • Authorization Code: Available for all MATTR credential formats (mDocs, CWT, JSON).
  • Pre-authorized Code: Only available for mDocs.
• Direct issuance: Submit a payload via API to be signed as a credential, then deliver it to the holder. Supported for CWT and JSON credential formats.

Underlying platforms

All issuance capabilities are provided through MATTR VII tenants, accessible via the MATTR Portal or API.
