EU eIDAS Trust Services and Wallet Readiness

Use this hub to separate eIDAS trust-service questions from EU Digital Identity Wallet work: signatures, seals, time stamps, registered delivery, website authentication certificates, electronic attestations of attributes, electronic archiving, electronic ledgers, qualified trust service providers, trusted lists, and relying-party data requests.

This is a practical reference, supporting implementation planning and should be validated against jurisdiction-specific legal, contractual, and policy requirements before implementation. Exact duties depend on whether you provide a trust service, rely on a trust service, issue or validate wallet data, or request attributes from a wallet user.

EU eIDAS questions this hub helps resolve
Trust-service category
Identify whether the work concerns electronic signatures, electronic seals, time stamps, registered delivery, website authentication certificates, attestations of attributes, archiving, ledgers, or validation services.
Qualified provider status
Check when a qualified trust service provider, qualified certificate, EU trust mark, conformity assessment, supervisory body, or trusted-list lookup is part of the evidence path.
Wallet relying-party readiness
Prepare service-provider registration, data-request purpose, PID and EAA validation, access certificates, privacy controls, and user-facing wallet acceptance flows.

Trust services
Start with the regulated service: signature, seal, time stamp, registered delivery, website authentication certificate, electronic attestation of attributes, archiving, ledger, or validation.
Provider checks
Use qualified status, certificate type, revocation and validity information, trusted lists, and supervisory-body context before relying on a certificate or service.
Wallet context
For EUDI Wallet use cases, distinguish wallet providers, PID providers, attestation providers, relying parties, service providers, and technical relying-party instances.
Use the linked guides to move from eIDAS terminology to the right operational artifact: scope, checklist, QTSP selection, wallet readiness, or source-linked research.
