Ask for the predicate
The site asks for over 18, over 21, or another eligibility claim. It does not ask for a birth date.
Verify the gate without becoming the next breach headline.
PROOFGATE verifies age or eligibility without asking your site to store a name, date of birth, ID number, or document image. The verifier checks a wallet presentation and returns the answer your gate needs: pass or fail, plus a non-reversible audit token.

Private by design
Get the answer. Do not keep the ID.
Most gated flows only need to know whether a user is old enough or eligible. PROOFGATE checks the credential presentation and keeps raw identity material out of your host system.
Your team receives a narrow result for access decisions and a minimal audit token for review. The user is not pushed through another document-upload funnel.
What the host gets
Zero stored PII
Answer
Pass or fail for the requested age or eligibility claim.
clear
Audit
A non-reversible token tied to the verification event.
minimal
Control
Issuer and claim policy can be reviewed before production use.
bounded
The acceptance layer. Not an ID warehouse.
PROOFGATE sits between your site and a wallet presentation. It validates the requested claim and returns the result your gate needs. Your system does not become an ID warehouse.
Verify the presentation
The wallet returns a credential presentation through a supported browser flow. The verifier checks the nonce, audience, issuer key, and disclosure binding.
Return the signal
The host receives pass or fail plus a non-reversible audit token. No identity record is stored.
Built for gates that do not need the whole ID.
PROOFGATE is strongest where the site needs an eligibility answer, not another database of sensitive documents.
Regulated retail
Teams selling age-gated goods need a durable age signal without making checkout feel like a document upload.
Eligibility platforms
Hosts can gate participation and keep a zero-PII audit token for disputes, reporting, and operator review.
Age-gated communities
Platforms can reduce underage access risk without asking every user to hand over identity records.
Built for wallet credentials, not ID uploads.
PROOFGATE is designed for selective disclosure: the wallet presents the claim needed for the gate, and the verifier checks the cryptographic proof. Credential and issuer coverage is reviewed during pilot setup.
SD-JWT VC
Selective disclosure lets a wallet reveal only the required predicate while the verifier checks cryptographic binding.
Browser-supported presentation
Where supported, the verification prompt can run through the browser Digital Credentials API. The goal is a direct wallet flow, not another hosted document upload.
mDL, ISO 18013-7
Mobile driver license support depends on issuer, wallet, and browser availability. Pilot scope should define which credential types are accepted before production traffic.
Metered pilots with a clear unit.
Each completed verification is one unit. Monthly minimums keep pilots serious while giving teams room to test the flow before a larger rollout.

This is a UI simulation of the drop-in result shape. It does not collect personal data and it does not call the cryptographic verifier from this marketing page. To run the real flow against the live verifier, open the live sandbox.

Best fit now: regulated retail, eligibility platforms, and age-gated communities that want an age-assurance signal without storing identity documents.
