An end-to-end EU Digital Identity Wallet proof of concept

About Registrų Centras

Registrų Centras - Lithuania’s State Enterprise Centre of Registers - operates the country’s core national registers, including the Real Property Register and the Register of Legal Entities, and runs the widely used LT ID identification solution. As a public institution at the heart of Lithuania’s digital infrastructure, it needed to understand - hands on - what the EU Digital Identity Wallet means for the services it provides to citizens.

The challenge

Under eIDAS 2.0, every EU Member State must offer citizens an EU Digital Identity Wallet, and public and private bodies will increasingly issue and accept credentials through it. For an organisation like Registrų Centras, that raises practical questions a specification alone cannot answer: How do we issue Person Identification Data (PID) to a citizen’s wallet? Can we reuse the identity systems we already operate, rather than rebuilding them? How does a citizen log in with their wallet, and how do we issue official records - such as a property extract - as verifiable credentials?

Registrų Centras wanted to answer these questions through a working proof of concept, and to build internal understanding of the wider EU Digital Identity Wallet ecosystem before committing to production work.

A proof of concept in two parts

Working with Soverio, Registrų Centras built a website prototype that exercises the full lifecycle of wallet-based identity, powered by the Soverio Wallet Gateway.

Part one - issuing identity to the wallet. A citizen first identifies themselves using Registrų Centras’s existing LT ID solution and signs in to the website. From the signed-in area, they order a new service: receiving their Person Identification Data into their personal EU Digital Identity Wallet. With the Soverio Wallet Gateway, Registrų Centras issues the PID, and it lands in the citizen’s wallet - reusing the identification the institution already trusts.

Part two - logging in and issuing an attestation. The citizen returns and logs in to Registrų Centras using the PID now held in their wallet, through the “login with wallet” capability of the Soverio Wallet Gateway - with no username or password to remember. Recognising a working wallet, the site offers a catalogue of credentials it can issue as Electronic Attestations of Attributes (EAA). The citizen requests an extract of their record from the national property register, and it is issued straight to their wallet as an EAA.

Sharing the knowledge

Technology was only half of the project. Before any code was written, Soverio ran a seminar introducing the EU Digital Identity Wallet ecosystem to staff across Registrų Centras - grounding the pilot in a shared understanding of the roles, standards, and citizen journey behind eIDAS 2.0.

The outcome

Both parts of the pilot were implemented and demonstrated successfully, end to end: identity issued to the wallet, login with the wallet, and an official registry credential delivered as an EAA - all on top of systems Registrų Centras already runs. The proof of concept gave the institution a concrete, working reference for how it can participate in the EU Digital Identity Wallet ecosystem, and showed how the Soverio Wallet Gateway makes that step achievable with minimal investment.
