Built for Fintech Compliance

You can't be sued for data you don't have.

Mathematically verified, zero-knowledge attestations for every regulated check.

Anchored on a public ledger. Verifiable forever. Nothing stored.

The Problem

Your KYC stack is your audit trail. It's also your breach surface.

Persona, Jumio, Onfido, Socure, Alloy — every identity vendor on the market ships you a customer file. That file is what you show your auditor. It's also your GDPR exposure, your discovery liability, and your largest unpriced operational risk. The thicker your audit trail, the larger your blast radius.

Traditional KYC stack
Customer files retained for 7+ years to meet BSA recordkeeping rules
ID scans, selfies, and PEP/sanctions logs aggregated in vendor databases
Every record creates GDPR, CCPA, NYDFS, and state privacy exposure
Breach insurance premiums scale with retention volume
Audit trail integrity rests on internal controls and vendor SOC reports
With ZeroVault
Mathematically verified attestation — no PII behind it to retain
Anchored to a public ledger as a tamper-evident audit artifact
Retention drops to zero by protocol, not by policy
Breach surface eliminated by construction — no record to leak
Auditor verifies the math directly, on-chain, with no vendor in the loop
How it works

Three steps. Nothing retained.

ZeroVault is the identity and attestation infrastructure for fintechs that won't accept the data liability of a traditional KYC vendor. We issue the credential. We verify the proof. We anchor the audit artifact. You retain zero PII.

01

Credential is issued

ZeroVault issues a verifiable credential at customer onboarding. Identity is verified once, against regulator-grade sources. The credential — not the underlying data — becomes the artifact your audit trail references.

02

Proof is verified

Your verifier checks a zero-knowledge proof against a public verification key in milliseconds. The check confirms the attribute — sanctions-clean, KYC-passed, accredited — without exposing the underlying data. No PII enters your stack.

03

Attestation is anchored

A compliance attestation is committed on-chain as a tamper-evident audit record. This is the artifact your auditor verifies, your regulator can spot-check, and your DPO sees as zero retention. Independently verifiable forever.
