Technical Purpose:

This regulation defines how EU Member States must register and communicate metadata about each officially notified EUDI Wallet to:

1. The European Commission

2. The Cooperation Group under the eIDAS 2.0 framework

The regulation ensures technical consistency, interoperability, and public verifiability of wallet registration across the EU.

Key Technical Requirements:

Data to Be Transmitted

Each Member State must prepare and submit a machine-readable dataset that includes:

• Wallet identifier (e.g., UUID or other persistent ID)

• Country code

• Legal issuer (organization issuing the wallet)

• Issuance date / Validity period

• Status of the wallet (e.g., active, revoked)

• Compliance details:

  • Reference to technical specifications used (e.g., eIDAS-compliant modules)

  • Security assurances (certification paths, conformance to ETSI/ISO/W3C standards)

Format and Transmission Protocol

• The dataset must be provided in a machine-readable format: likely JSON, XML, or a defined structured schema (e.g., based on CEF Building Blocks).

• It must comply with a standard data model (to be maintained by the Commission), likely part of the broader EUDI Wallet Registry schema.

Example (conceptual JSON structure):

{
  "wallet_id": "urn:eu:wallet:abc123",
  "issuer": "DigitalID Authority of CountryX",
  "country": "X",
  "status": "active",
  "valid_from": "2025-10-01",
  "standards": ["ETSI TS 119 461", "W3C Verifiable Credentials"],
  "signature": "<digital signature>"
}

Notification and Updates

• Wallet data must be transmitted to the Commission:

  • Upon initial notification

  • Any time a wallet is updated, suspended, or revoked

• The information must be sent without undue delay, ensuring real-time registry integrity

Central Wallet List

• The European Commission will maintain a central machine-readable list of all notified EUDI Wallets

• This list will be:

  • Publicly accessible

  • Regularly updated

  • Published in the Official Journal of the EU and stored in structured, queryable formats

Security Considerations:

• Submissions are expected to be digitally signed to ensure authenticity and integrity

• Trust frameworks like PKI, Qualified Certificates, and/or EU Trust Lists (LOTL/TL) may be required to validate sources

Deadlines:

• Regulation becomes applicable 20 days after publication in the EU Official Journal (OJEU)

• Member States must comply immediately after that date
