Getting Started

The issuer API allows you to sign and issue W3C credentials in JWT and SD-JWT format via OID4VC. The issuer and subject can be identified by various DID methods like did:key, did:jwk, did:web, did:cheqd and more. Use data functions to dynamically populate the credential with up-to-date information from your backend during issuance.


  • Open-Source - Use the issuer API available via the identity-repo.


  • Keys / DIDs - Generate and use keys/DIDs secured by an external KMS or your custom storage.
  • Credentials - Issue credentials via OID4VC.
  • Data Functions - Populate credentials with up-to-date information.


  • EBSI - Issue credentials that are compliant with the European Blockchain Services Infrastructure (EBSI).
