ZeroVault
Private Access
Zero-Knowledge Identity Infrastructure

Prove it.
Without revealing it.

ZeroVault enables cryptographic proof of payment validity, travel authorization, and identity claims — without transmitting a single digit of underlying credential data.

🔐
On-device cryptography

All ZK circuits run locally via WASM. Raw data never transits any network.

Single-use proof tokens

Every proof is cryptographically bound to a specific verifier and expires.

🛡
Replay-proof by design

A stolen token is mathematically useless — no replay against a different verifier.

🌐
Open standards only

W3C VC 2.0, ISO 18013-5, OID4VP — interoperable across wallets and networks.

Architecture

Four steps.
Zero exposure.

Credential data stays on your device. Verifiers receive a mathematical proof — nothing else, ever.

🔐
Enroll

Add a card or passport. A Pedersen commitment is generated locally. Raw data is immediately discarded.

📋
Register

Your commitment enters the issuer's Merkle tree and is signed as a W3C Verifiable Credential.

Prove

A zk-SNARK circuit runs on-device via WASM, generating a single-use proof token bound to the verifier.

Verify

The verifier checks the proof against the public circuit. They learn only: valid or invalid. Nothing else.

Provable claims

What gets proven.
What stays private.

Selective disclosure at the cryptographic layer — not policy.

01
Data never leaves your device

A Pedersen commitment (one-way hash) is generated locally. The raw credential is discarded. The commitment cannot be reversed — mathematically guaranteed.

02
Zero-Knowledge Proofs (zk-SNARKs)

ZKPs let you prove a statement is true without revealing the supporting data. The verifier receives a proof token and verifies it cryptographically. They learn only the truth value — nothing else.

03
W3C Verifiable Credentials

Proofs are packaged as W3C VCs — the open standard used by governments, airlines, and payment networks. Compliant with ISO 18013-5 and IATA One ID.

04
Fraud-proof by cryptography

Every proof is verifier-bound and time-limited. A stolen token cannot be replayed — tied to one transaction, one verifier, one moment. Nothing to intercept, nothing to steal.
