Register as a Wallet-Relying Party

Registering as a wallet-relying party gets your service onto the iGrant.io recognised Trust List, so the Data Wallet shows a verified badge for your organisation instead of the "Service provider not verified" warning. This guide covers the NXD Test Network, where the recognised Trust List is operated through the NXD Trust List for development and piloting.

Test network scope: This is a test-network onboarding for developing and piloting against the Data Wallet. It mirrors the wallet-relying party registration pattern from eIDAS, but it is not the legal registration with a Member State national register. The recognised Trust List used here is operated as a test network through the NXD Trust List. Use it to make your service trusted during development, then follow your national register's process for production.

Background: What a wallet-relying party is​

Under eIDAS, a relying party that wants to request credentials from EU Digital Identity Wallets registers as a wallet-relying party. Commission Implementing Regulation (EU) 2025/848 defines it as:

"'wallet-relying party' means a relying party that intends to rely upon wallet units for the provision of public or private services by means of digital interaction"

In production this registration is with a national register operated by a Member State registrar, providing the information in Annex I of the regulation. The NXD test network mirrors that pattern so your service can be recognised during development.

Step 1: Prepare your certificate and key id​

To register you need an X.509 certificate and its key id (kid). You can provide your own, or generate them with the Certificate Generator:

  • Open the Certificate Generator, fill in your organisation details, choose the service type, and provide your CSR.
  • It returns an X.509 certificate, the key id (kid) as an RFC 7638 JWK thumbprint, and a trust-list entry in JSON with the certificate embedded. Copy the kid and the entry into the form in Step 2.

Using the Certificate Generator is optional. If you already have a certificate and kid, use those.

Subject to verification: Everything you submit is reviewed and verified by iGrant.io before your service is added to the recognised Trust List. If you use the Certificate Generator, note that it produces a self-signed test certificate. Please ensure the data you enter is real and aligned with your official records.

Step 2: Submit your registration request​

Fill in the form below and choose Submit registration request. This opens your email client with the request, including your certificate and trust-list entry, pre-filled to [email protected]; review it and send. After verification, the iGrant.io team adds your entry to the recognised Trust List for you.

Certificate and trust-list entry:

Your certificate and entry are included in the email, so there is nothing to attach. If your email client shortens long messages, attach them as a file instead.

Note: For the test network, iGrant.io handles the trust-list update on your behalf, so there is no pull request for you to raise. Self-service submission is planned for a later release.

Step 3: Confirm you are recognised​

Once iGrant.io has added your entry and the Data Wallet has refreshed its trust lists, your organisation is matched against the recognised Trust List. Users then see the verified badge for your service instead of the "Service provider not verified" popup.
