EUDI Wallet: A Practical Guide for Relying Parties

Understand the ecosystem, attribute requests, trust decisions and integration questions behind wallet-based identity journeys in Europe.

From identity document upload to credential presentation

The European Digital Identity Wallet framework enables people and businesses to use digital identity data and electronic attestations across services. A relying party asks for appropriate attributes; the wallet holder reviews and presents them through the applicable trust and protocol framework.

The European Commission’s EUDI Regulation overview and continuously updated Wallet Toolbox are primary references for implementation planning.

Design the whole relying-party journey

  1. Determine the legal and business purpose for each requested attribute.
  2. Register or identify the relying party as required for the use case.
  3. Request the minimum appropriate data or proof.
  4. Allow the wallet holder to understand and approve the disclosure.
  5. Validate presentation integrity, issuer trust, status and binding.
  6. Translate verified attributes into the service decision.
  7. Retain only the evidence and data required for the defined purpose.
Wallet acceptance is not only an API integration

Teams must align product, privacy, compliance, security, trust-list handling, customer support and fallback journeys.

Decisions to resolve early

Which attributes or derived proofs are necessary?
Which issuers and credential types are accepted?
How are status and revocation checked?
How is the wallet holder bound to the session?
What evidence is stored for audit?
What fallback applies without a wallet?
How are cross-device journeys handled?
How are framework updates governed?

Evaluate EUDI Wallet infrastructure providers

Distinguish wallet issuance, credential issuance, trust services, relying-party connectivity, orchestration and verification. A provider may cover one layer or combine several.

  • Protocol, credential format and interface support
  • Trust-list, certificate and status validation
  • Selective disclosure and data-minimisation controls
  • Mobile, cross-device and accessibility journeys
  • Sandbox quality, conformance evidence and release management
  • Fallback to existing eID or verification methods
