EUDI Wallet for developers
Independent technical overviews for developers integrating the EUDI Wallet: which standards apply, which versions are current, and what the implementing regulations actually require. We explain and link to the originals instead of copying them.
Standards overview
OpenID4VCI, OpenID4VP, HAIP, SD-JWT VC, ISO mdoc and the ETSI profiles: what each does, current versions and what the regulations require.
How the EUDI Wallet works
Issue, present, verify: the flow, selective disclosure and the safeguards against misuse, with a diagram.
Spec tracker
New versions of OpenID4VC, SD-JWT VC, Token Status List, ISO mdoc, the ETSI profiles and the ARF – checked daily at the publishers, dated, as JSON and Atom feed.
Reference implementation
All open-source building blocks from the Commission by role – wallet apps, libraries, issuers, verifiers, signing – with licence and latest release.
Glossary
Key legal and technical terms with references to the regulation or specification, one anchor per term.
Open data: EUDI Index
Wallet status for all 27 member states, as JSON and CSV under CC BY 4.0.
Coming next
Sandboxes and national wallets
Which member state offers what: sandboxes, test wallets and open-source national wallets, with access and licence.
Register statistics in the API
From 24 December 2026 the API reports daily which national relying party registers are reachable; from January 2027 statistics across all countries.
