The compliance attestation layer for regulated data.
A four-layer cryptographic stack that proves identity and compliance checks happened — without storing the data behind them. This page is the plain-English version: what we built, why the category matters, and what to verify in diligence.
Identity is the wedge. Compliance attestations are the category.
Every regulated industry runs the same loop: verify a customer attribute, store the evidence, prove it to an auditor years later. The evidence is the file you keep. The file you keep is the breach you're going to suffer.
ZeroVaultID inverts the loop. The verification still happens — but the artifact you keep is a mathematically verified attestation, not the underlying data. The attestation is anchored on a public ledger as tamper-evident proof. The customer's PII never enters your systems. Your audit trail is shorter, stronger, and uncopyable.
Identity verification is the universal first wedge because every regulated industry has to do it. But the same primitive proves AML checks, sanctions screening, healthcare consent, accreditation status, residency, age — anywhere data minimization meets audit requirements. One engine. Every regulated check.
Four layers. Each one provable.
The stack is composed of four production layers working together. Each layer is built on open standards and is independently verifiable — there is no proprietary trust assumption a regulator has to take on faith.
Verifiable credential
The customer holds a W3C Verifiable Credential issued by a trusted authority — a bank, government, or qualified issuer. We don't issue credentials. We don't store them. We work with whatever the customer already has.
Zero-knowledge proof
The proof is generated in the customer's browser. The required attribute (age, residency, accreditation) is mathematically demonstrated without revealing the data behind it. The proof is small, fast to verify, and reveals nothing else.
VRID attestation engine
Patent-pending compliance attestation format. Records that a specific check passed at a specific time — without recording any of the underlying data. The attestation is the artifact your auditors and regulators verify. Replay-resistant, audit-compliant, lookback-ready.
L2 anchor
Attestations are anchored on a public Layer 2 network for tamper-evidence. Anyone — auditor, regulator, counterparty — can independently verify the attestation was issued by ZeroVault at the recorded time. Multichain support is on the roadmap.
Banks, networks & financial institutions
- KYC & KYB attestations — prove the check happened, store nothing
- Sanctions screening attestations — verifiable, replayable, audit-compliant
- AML transaction monitoring attestations — verified evidence for SAR support
- Accredited investor verification — Reg D / Reg CF–compatible
- Cross-border identity attestations — for correspondent banking and CMS
Regulators & government
The pitch in one sentence
An attestation format your regulated entities can give you that you can verify directly — without taking custody of citizen data and without trusting the regulated entity's word for it.
Why this changes audits
Today, when a regulator needs to verify that a bank ran KYC on a customer, the bank produces a file. The regulator trusts the file. The file is mutable. With mathematically verified attestations, the regulator verifies the math directly. The attestation cannot have been forged after the fact. It's a strictly stronger audit primitive.
- eIDAS 2.0 compatible — selective disclosure built in
- EUDI Wallet integration — attestation format aligns with EUDI architecture
- BSA / FinCEN-compatible audit trails — without citizen data exposure
Investors & partners
What's been built
A live four-layer ZK identity compliance stack with a working demo, a production MATTR VII tenant, smart contracts deployed and validated on Base, and 8 provisional patents filed under a Delaware C-Corp. Solo founder build to date — actively recruiting a technical co-founder.
The market motion
Three regulatory tailwinds converging on the same primitive: eIDAS 2.0 (EU, 2026 deadlines), state-by-state age verification laws (UK, EU, Texas, Louisiana), and agentic commerce identity (Visa and Mastercard publicly identified this as a 2026 priority). Card networks are the marquee account; crypto-native banks and BaaS providers are the velocity accounts.
What we're working on
- Design partner conversations with card networks and chartered digital-asset banks
- EU institutional positioning — TAO ROOT, EBSI, eIDAS-aligned identity flows
- Technical co-founder — Aztec / Noir ecosystem, ZK cryptographer
- Pre-seed round — financing the first design partner deployments
Eight provisional patents. One coherent moat.
All eight provisionals are filed pro se via USPTO Patent Center as a micro entity, all assigned to ZeroVaultID, Inc. Non-provisional deadlines fall in April 2027. The portfolio covers the attestation format, the verification architecture, the trust resolution layer, and the data-elimination protocol.
VRID method & four-layer stack
The core compliance attestation method and the four-layer architecture connecting verifiable credentials, zero-knowledge proofs, the attestation engine, and on-chain anchoring.
Quantum-resistant architecture
Post-quantum attestation architecture providing 128-bit security against future quantum adversaries. Details disclosed under NDA only.
Multi-jurisdiction trust resolution
Adaptive trust resolution for decentralized identity infrastructure spanning multiple regulatory jurisdictions, allowing the same attestation to satisfy auditors across EU, US, and APAC frameworks.
Attestation format & verification primitives
Auxiliary patents covering the attestation encoding, replay-bundle format, audit-compliant lookback methods, and selective disclosure primitives across the stack.
Zero-retention ephemeral input processing
System for processing identity inputs with device attestation and pre-commitment data elimination — the primitive that makes "we never had the data" mathematically demonstrable, not just policy-stated.
Combined moat
Together the eight cover the attestation format, the verification architecture, the trust layer, and the data-elimination protocol — making it difficult to ship a competitive zero-disclosure compliance stack without crossing the portfolio.
Verifiable, not claimed.
Everything below is independently verifiable by you, today, without our involvement. We don't ask for trust — we ask for verification.
