CSC Interoperability Event 2026 Concludes in Bucharest with Strong Industry Momentum

The Cloud Signature Consortium (CSC) successfully concluded its Interoperability Event 2026, held on 17–18 March in Bucharest and hosted by certSIGN. Bringing together EUDI Wallet providers, Qualified Trust Service Providers (QTSPs), and technology innovators from across Europe, the event marked an important step forward in advancing interoperability within the European Digital Identity ecosystem.

Over two days, participants moved beyond discussion to hands-on collaboration, testing real-world implementations of the CSC API within the EUDI Wallet framework. The programme combined strategic insights with deep technical engagement, covering remote signing use cases, API validation, and interoperability testing across multiple providers.

Day 1 focused on setting the context and technical groundwork, with sessions exploring the role of the CSC API in enabling secure, cross-border digital signatures. Participants then moved into environment setup and scenario planning, preparing for live testing.

Day 2 brought these efforts to life through live interoperability testing, cross-provider integrations, and real-world use case validation. Teams worked collaboratively to test, refine, and demonstrate their solutions, culminating in live demos and innovation showcases.

The event concluded with an awards ceremony recognising outstanding contributions. Intesi Group was named the winner of the CSC Interoperability Event 2026, highlighting their strong performance and commitment to advancing the CSC API ecosystem.

The Interoperability Event once again demonstrated the value of bringing the ecosystem together in a practical, testing-driven environment. As the European Digital Identity Wallet moves closer to large-scale deployment, initiatives like this play a critical role in ensuring technical readiness, alignment, and trust across stakeholders.

CSC extends its sincere thanks to all participants and to certSIGN for hosting the event in Bucharest.

The conversation continues at the upcoming Trust Without Borders Summit 2026 in Bogotá, where the global digital trust community will further explore the future of identity, signatures, and cross-border interoperability. Visit www.cscsummit.com for more information.
