Preparatory Webinars

CSC Interoperability EUDI Wallet 2026 - Preparatory Webinars

To support participants in their preparation for the CSC Interoperability EUDI Wallet 2026, Cloud Signature Consortium is organising a series of three preparatory webinars. These webinars are designed to provide both a practical and technical overview of the Plug Test, covering logistics, technical prerequisites, API-related topics, and innovation-focused discussions. 

Participation in the webinars is open to all and does not require prior registration for the Plug Test, although participants are of course encouraged to join the Plug Test itself.

Frequently Asked Questions
Do I need to have an existing EUDI Wallet integration? 
No. CSC provides a reference wallet implementation in the POTENTIAL Playground sandbox. You can test against that, or bring your own wallet implementation if you have one.
Can I attend remotely?
The event is in-person to maximize hands-on learning and peer collaboration. 
What if I'm not ready to compete?
CSC Interoperability EUDI Wallet 2026 Only participation is available. You'll get the same technical mentorship, testing environment, and learning experience – just without the competitive demo & judging.
What if I have technical questions before the event? 
Join our prep webinars, or email info@cloudsignatureconsortium.org with questions.
