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.
