Blueprint for the EUDI Wallet Ecosystem in Germany

Purpose of the Blueprint

This document is part of Germany’s consultation process for implementing the EU Digital Identity Wallet (EUDIW). It proposes architectural, governance, and operational models for a national EUDI Wallet ecosystem that is interoperable across the EU while respecting Germany’s legal, technical, and institutional landscape.

The blueprint is based on:

  • the eIDAS 2.0 Regulation
  • the Architecture and Reference Framework (ARF)
  • relevant ETSI specifications
  • national requirements and identified use cases

It serves as a discussion and design basis, not as a final or binding specification. Future ARF updates and Implementing Acts may influence the final design.

How to Read This Document

This blueprint is structured into four main parts, each addressing a different concern:

  1. Ecosystem Vision & Fundamentals
    Explains why the ecosystem exists, its guiding principles, and how it fits into the broader EUDI context.

  2. Ecosystem Governance & Operation Model
    Describes who sets the rules and who operates the ecosystem, including onboarding, certification, supervision, and lifecycle management.

  3. Ecosystem Architecture
    Explains how the ecosystem works technically, including roles, trust relationships, validation mechanisms, and protocol usage.

  4. Appendix
    Contains detailed flows, rulebooks, and deep dives referenced from the main chapters.

A detailed reading guide is provided in How to Read This Blueprint.

Audience

This document is intended for:

  • policy makers and regulators
  • public and private service providers
  • wallet and relying party implementers
  • auditors and conformity assessment bodies
  • standards and ecosystem contributors
  • other interested parties or individuals that want to better understand the ecosystem

Different sections are relevant depending on the reader’s role.

Looking for Wallet implementation details?

This blueprint describes the ecosystem and trust architecture, not a concrete wallet implementation. Please refer to the Architecture Documentation of the German National EUDI Wallet for implementation-specific architecture, flows, and interfaces.
