Organisations should define acceptance criteria for each use case, including assurance level, attribute freshness, transaction context, and relying-party verification. A wallet claim is only useful when the receiving system knows exactly what it is willing to trust and what evidence still needs to be checked locally.
What makes an EUDI wallet claim acceptable in practice?
An eudi wallet claim should be accepted only when the relying party has a clear rule for that specific use case, not a vague trust posture. Acceptance depends on whether the claim’s assurance level, freshness, context, and verification evidence are sufficient for the decision being made, and whether anything still needs local validation before the system acts on it.
That means the same wallet claim can be acceptable for one transaction and unsuitable for another. A low-risk lookup may tolerate a lighter rule set, while account opening, entitlement changes, or legal commitments usually require tighter evidence, stronger assurance, and explicit linkage to the current transaction.
How to define acceptance criteria for a wallet claim
The most useful acceptance criteria are written from the relying party outward, starting with the action the organisation wants to permit. The organisation should decide which attributes matter, what level of assurance is required for the wallet assertion, how recent the claim must be, and whether the transaction context matches the intended purpose.
Freshness matters because a claim can be correct and still no longer be safe to rely on. If the decision depends on current employment, age, address, authorisation, or another mutable attribute, the organisation should define how often that evidence must be refreshed and what local re-checks are required when the claim is older than the tolerated window.
Context matters because a valid claim in one channel may be inappropriate in another. Acceptance criteria should distinguish between informational use, step-up verification, and high-impact actions, so the relying party can reject a claim that was issued for a different purpose, audience, or transaction path.
Where local verification still has to stay in the loop
A wallet claim should not be treated as a universal substitute for local control. The receiving system may still need to check fraud signals, authorization state, policy constraints, revocation status, or business rules that are specific to the organisation’s own environment.
For wallet-driven trust to work well, the relying party must know which parts of the decision are delegated to the wallet and which parts remain local. In practice, the most robust designs use the wallet as an evidence source, then apply local policy to decide whether the claim is sufficient for eIDAS 2.0 use in the organisation’s own workflow.
That separation is especially important when the claim is used to unlock a sensitive action rather than simply prove a statement. If the relying party cannot explain why the claim is trusted, what it covers, and what it does not cover, it should not automate acceptance.
Risk and Threat Considerations
Wallet claims create exposure when organisations over-trust portability and under-specify their own acceptance rules. A claim can be genuine yet still be the wrong answer for the transaction, and a technically valid presentation can still enable fraud, privilege inflation, or stale-attribute abuse if the relying party does not test freshness, purpose, and local policy.
Failure mechanism: The system accepts a claim because it came from a wallet, without checking whether the claim was issued for the correct purpose, whether the attribute is still current, or whether the relying party needs an additional local control before acting.
Impact: Inappropriate acceptance can lead to false trust, incorrect onboarding or access decisions, and a wider blast radius if a stale or over-broad claim is reused across multiple services or transactions.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST SP 800-63, NIST CSF 2.0 and OWASP ASVS set the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-63 | Digital Identity Guidelines | Wallet claim acceptance depends on assurance, proofing, and verifier expectations. |
| Recommendation — Align acceptance criteria to assurance and verifier requirements before relying on the claim. | ||
| NIST CSF 2.0 | PR.AA-05 — Identity Management, Authentication, and Access Control | Acceptance criteria govern when a claim is sufficient for access or a transaction. |
| Recommendation — Define claim acceptance rules that enforce identity and access decisions consistently. | ||
| ISO/IEC 27001:2022 | A.5.15 — Access control | Relying parties need policy-defined conditions for accepting identity evidence. |
| Recommendation — Document claim acceptance policy as part of access control governance. | ||
| OWASP ASVS | V10 — OAuth and OIDC | Wallet-based acceptance relies on federated identity and verifier-side trust decisions. |
| Recommendation — Verify the trust and token acceptance path before treating a wallet claim as sufficient. | ||
Practitioner Guidance
What to prioritise: Start with the highest-impact use cases first, then write acceptance criteria that are specific enough to drive an allow or deny decision. If the use case affects money movement, identity binding, entitlement changes, or regulated actions, treat freshness and assurance as hard gates rather than advisory checks.
What to verify: Confirm that each claim can be tied to a defined relying-party policy, a defined freshness window, and a defined transaction context. Also verify which checks remain local, because an acceptable wallet claim still may not be sufficient on its own for the final decision.
Practitioner takeaway: The safest pattern is not to ask whether a wallet claim is generally trustworthy, but whether it is trustworthy enough for this exact decision, at this exact time, under this exact policy.
