EUDI wallet sandbox in Lithuania: what it means for rollout readiness

TL;DR: Procivis says Lithuania has selected it to provide a national sandbox for the European Digital Identity Wallet, creating a test environment for secure, user-centric wallet use cases, cross-border verification and eIDAS 2.0 readiness ahead of the EU-wide 2026 rollout. Early validation matters because interoperability, security and usability have to be proven before scaled deployment.

Editorial analysis by NHI Mgmt Group, based on content published by Procivis: “Lithuania Selects Procivis for the National European Digital Identity Wallet Sandbox”.

Key questions

Q: How should governments validate digital identity wallets before national rollout?

A: Governments should validate digital identity wallets in controlled environments that test issuance, verification, relying-party integration and cross-border use cases together.

Q: Why does interoperability matter so much in EUDI wallet programmes?

A: Interoperability matters because a wallet only has value if issuers, verifiers and relying parties can interpret the same credential in the same way.

Q: What breaks when digital identity assurance is tested too late?

A: When assurance is tested too late, teams discover mismatches in policy, attribute handling, verification logic and relying-party expectations after the programme is already committed to rollout.

Practitioner guidance

• Build a relying-party test plan Validate every external service that will consume wallet credentials, including public services and private-sector relying parties, before production enrolment begins.
• Define readiness criteria for assurance and interoperability Set measurable acceptance thresholds for issuance, verification, cross-border presentation and exception handling so programme status reflects operational reality.
• Use sandbox testing to expose trust gaps Exercise end-to-end identity journeys with real service integrations to find where policy, presentation or verification logic diverges.

Bottom line: National wallet programmes fail most often at the boundaries between issuance, verification and relying-party acceptance, not inside the wallet itself.
