Wallet-Relying Party Registration
This document introduces Wallet-Relying Party Registration - a framework that enables EUDI Wallet users to know and trust who they're sharing data with. By requiring all organizations to register publicly before they can interact with wallets, the system provides transparency about who's asking for data, what they're authorized to request, and why they need it.
Whether you're a Member State planning a national register, an organization preparing to register, or simply wanting to understand how the system works, this guide covers the fundamentals in plain language with visual diagrams.
What is a wallet-relying party?
A wallet-relying party is any organization that interacts with EUDI Wallets to provide digital services. This is a broad category that includes two main types:
Service Providers (Verifiers) ask users to prove something about themselves - like proving you're over 18 to buy age-restricted items, or proving your identity to open a bank account.
Attestation Providers (Issuers) give users digital credentials - like a university issuing your diploma, or a government issuing your driver's license data.
Some organizations are both - for example, a university might verify your enrollment status before issuing you a student ID credential.
Why is wallet-relying party registration needed?
The EUDI Wallet ecosystem involves millions of users sharing sensitive data with thousands of organizations across 27 countries. Without a standardized registry system, users would have no way to verify if an organization is legitimate, what they're authorized to request, or how to report issues.
Registration solves this by creating transparent, publicly auditable directories that enable:
- User protection: Users can verify organizations before sharing data and understand what each organization is authorized to request
- Automated verification: Wallets can automatically check authorization without users needing to research every organization
- Cross-border trust: A German user can trust a French bank without complex bilateral agreements between countries
- Accountability: Member States can oversee and enforce rules for organizations operating in their jurisdiction
- Transparency: Anyone can audit which organizations are registered and what they're authorized to do
