Blueprint for the EUDI Wallet Ecosystem in Germany

Introduction

This document, developed as part of Germany’s consultation process for implementing the EU Digital Identity Wallet (EUDIW), explores technical architecture options, governance and operating models, and related considerations.

Based on the eIDAS v2 regulation and the Architecture and Reference Framework (ARF), it proposes a national wallet architecture tailored to Germany’s eID system, decentralized registers, and identified use cases. The aim is to ensure interoperability with the EUDI ecosystem across all EU member states while meeting security, privacy, and user experience requirements, and establishing a viable governance and economic model.

It serves as a discussion basis, outlining possible approaches for a decentralized, secure, and privacy-friendly wallet, recognizing that future ARF updates and implementing acts may influence the final design.
