Technical Specifications

While the EUDI Wallet relies primarily on recognised standards and technical specifications (STS), certain implementation details require additional, fast-track guidance.

To bridge these gaps, the European Commission, in collaboration with the European Digital Identity Cooperation Group and the European Standards Organisations (ESO), develops complementary technical specifications.

These EC-authored specifications:

• address short-term implementation needs not yet covered by existing standards,
• provide concrete guidance on interfaces, data formats, and trust mechanisms, and
• serve as input for future standardisation under ESO responsibility.

All technical specifications are published openly on GitHub, following a transparent and collaborative drafting process that allows stakeholders to comment and contribute.
