There a couple of open-source projects implementing SD-JWT VC.

Here are two that were implemented by the European Commission:

  *
https://github.com/eu-digital-identity-wallet/eudi-lib-jvm-sdjwt-kt
  *
https://github.com/eu-digital-identity-wallet/eudi-lib-sdjwt-swift

Here is another one in Kotlin:

It's a step removed from implementation but SD-JWT VC was included in the 
February update of the EU draft implementing acts for the European Digital 
Identity Wallet:

EUDI Wallet standards and technical specifications 
update<https://ec.europa.eu/info/law/better-regulation/have-your-say/initiatives/16112-European-Digital-Identity-Wallet-standards-and-technical-specifications-update-_en>
EUDI Wallet registration of wallet relying parties

Hi Oliver, hi Daniel, hi Brian!

As part of the shepherd write-up for the SD-JWT-based Verifiable Digital
Credentials (SD-JWT VC) document, we are gathering information about
implementations of  the draft.

Any input you can share for inclusion in the write-up would be
appreciated. There are certainly a lot of implementation activities ongoing.

Ciao
