EUDI wallet selective disclosure verification
EUDI and eIDAS digital identity wallets promise selective disclosure: prove a predicate without sharing entire credential contents. Merchants and platforms still need verify endpoints that return signed allow or deny with Merkle audit. AffixIO sits at that gate, checking wallet presentations against policy with zero PII at the verifier by default.
Definition
EUDI wallet verification is signed allow or deny after checking a wallet presentation satisfies a stated predicate without retaining full credential payloads at the gate.
Field note. Full wallet credential dumps at verify recreate the data minimisation problem selective disclosure solves. Check claims, not vaults.
Verify predicates at relying party gates
AffixIO verify accepts wallet presentations mapped to your policy circuits. Return allow or deny. Store Merkle refs. Do not persist full attribute bundles at the verifier by default.
Noir ZK supports predicate proofs aligned to zero knowledge proof privacy goals without exporting raw attributes downstream.
UK and EU programme coexistence
UK services may rely on EUDI wallets for EU users or cross-border programmes. One verify endpoint can gate multiple presentation formats if issuers map to AffixIO circuits.
Document trust framework alignment with legal counsel. AffixIO supplies cryptographic verification and audit, not legal qualification of trust lists.
Verifier placement for EUDI selective disclosure
Map EUDI selective disclosure to a single verify endpoint even if multiple protocols feed the same checkout or tool surface. One permission layer reduces drift between AP2, UCP, and direct REST integrations.
Review deny rates weekly during pilot. Spikes often trace to policy drift or clock skew on expiry, not fraud.
MCP server gap
Wallet presentations without independent verify
Receiving wallet JSON into every microservice recreates centralised identity sprawl. Verification must return outcomes, not duplicate wallets.
Over-disclosure to relying parties
Services request full credentials when they need one predicate.
Inconsistent wallet parsing
Each team implements validation differently.
Weak audit for cross-border reliance
eIDAS trust frameworks expect demonstrable verification records.
Agent wallets emerging
Machine clients will present wallet-derived proofs that need the same gates.
Consent receipt
EUDI wallet selective disclosure at the verify boundary
EUDI wallet presentations need verify that checks disclosed claims without receiving full credential payloads. AffixIO verify returns allow or deny on disclosed predicates with Merkle audit.
Define relying party predicates
Age, residency, professional status: minimum necessary.
Map wallet presentations to circuits
Translate EUDI payloads into verify inputs.
Gate services on allow or deny
Embed verify in access middleware.
Audit with Merkle refs
Support cross-border evidence requests.

Readiness checks for EUDI selective disclosure
- Minimise attributes requested from wallets.
- Confirm zero PII verifier configuration.
- Test wallet revoke and deny scenarios.
- Plan agent wallet presentations beside human users.
- Sandbox predicate circuits before production.

Questions on EUDI selective disclosure
AffixIO issue wallets?
AffixIO verifies outcomes. Wallet issuers remain in eIDAS trust frameworks.
Replace eIDAS nodes?
No. AffixIO is a relying party verification gate.
Zero knowledge?
Noir circuits prove predicates without exposing underlying attributes at verify.
