A new era: ADACOM and Lissi partner to drive EUDI Wallet adoption in Greece

We are delighted to announce our strategic alliance with ADACOM. As a leading European Qualified Trust Service Provider (QTSP), ADACOM brings in-depth expertise in the areas of PKI, electronic signatures and digital identity solutions to this partnership. Together, we are building the technological bridge that will enable companies and public authorities not only to meet the requirements of the eIDAS 2.0 Regulation, but also to actively shape it.

Bundled expertise for digital sovereignty

The combination of Lissi's modern EUDI Wallet Connector API and ADACOM's proven trust infrastructure creates a comprehensive offering. The aim is to make the integration of the European wallet infrastructure as easy as possible for organisations.

  • Local roots, European standard: Customers in Greece benefit from a solution that perfectly combines local compliance requirements with the cross-border interoperability of the EUDI framework.
  • Seamless integration: Thanks to standardised interfaces, wallet acceptance (KYC and EAA) can be implemented without any major changes to existing specialist applications.

From theory to practice: validated use cases

ADACOM and Lissi have already successfully demonstrated that the technology is ready for use today. Complex scenarios have already been successfully piloted in a dedicated sandbox environment integrated into ADACOM's infrastructure:

  • Fully automated KYC: Digital identity verification for highly regulated sectors such as banking.
  • Digital credit processes: Efficient processing of loan applications through verified data.
  • Legally compliant signatures (QES): The direct combination of wallet data with qualified electronic signatures for maximum evidential value.

Feedback from the initial implementation phases confirms that integration is proceeding smoothly and significantly reducing technical complexity for end users and businesses.

A strategic roadmap for eIDAS 2.0

This partnership is more than just technical cooperation – it is strategic preparation for Europe's digital future.

ADACOM integrates Lissi's technology as part of a white label model to expand its own portfolio in a targeted manner. A particular focus here is on developing into a provider of Qualified Electronic Attestations of Attributes (QEAA). This will enable ADACOM to issue legally compliant digital credentials – such as professional qualifications or licences – directly to citizens' wallets.

"Working with Lissi allows us to consolidate our position as an innovation leader in the field of trust services and offer our customers a turnkey solution for the upcoming eIDAS requirements." – Kostas Nousias, Trust Services Director, ADACOM.

Together, Lissi and ADACOM are pursuing the vision of accelerating the market launch of the EUDI wallet in Greece and establishing a secure, user-centred identity infrastructure.
