Interoperability

European Digital Identity Wallet interoperability matrix.

Interoperability with the European Digital Identity Wallet ecosystem varies by wallet vendor, credential format (SD-JWT VC vs mDoc), device-topology (same-device vs cross-device), and trust framework (LOTL vs national list). The table below lists the wallets whose interoperability we have tested against our verifier. Empty cells reflect combinations we have not exercised in a formal test run; blank rows are not a statement about wallet quality.

Our verifier is spec-conformant per the OpenID Foundation OID4VP + HAIP conformance harness (alpha) — see the HAIP verifier certification page for the certified test outcomes. Interop against any specific Member-State wallet is a separate exercise.

Wallet Country Version Test date SD-JWT VC mDoc Same-device Cross-device Notes
EUDI reference wallet EU (reference implementation) OID4VP 1.0 FINAL + HAIP 1.0 FINAL profile 2026-07-19 yes primitives only yes yes Runs against the OpenID Foundation OID4VP + HAIP conformance harness (alpha). SD-JWT VC end-to-end, encrypted direct_post.jwt responses (ECDH-ES + A128GCM / A256GCM). mDoc primitives exist in-tree; end-to-end mDoc verification is not part of this run.
Aloaha Web Wallet Malta (Aloaha Limited) 2026-07-x 2026-07-19 yes no yes yes Our own browser holder. Not a government-notified EUDI Wallet. Designed for LoA-Substantial-targeted use cases subject to a formal conformity assessment. See the explainer.

Additional rows will be published for other Member-State wallets as tests are executed and evidence bundles are prepared. The verifier speaks the standards; the empty cells are a matter of published test scope, not spec support.
