After shipping OpenID4VP support last year and migrating all Privacy by Design issuers to SD-JWT VCs earlier this year, today we're closing the loop: Yivi now supports both OpenID4VCI and OpenID4VP. Issuers and verifiers can integrate with Yivi entirely using open standards.

We're opening a private BETA and inviting organizations to be among the first to integrate.

A Yivi user loads in his eduID and discloses it using OpenID4VP using Veramo verifier software.
