HashVex generates tamper-proof ZK proofs for every ad conversion — independent of Google, Meta, or any platform. Your ground truth, cryptographically signed.
Four steps. No cookies. No ad platform trust required. Just math.
User clicks your ad. gclid, fbclid, or li_fat_id is captured server-side — before JavaScript runs, invisible to ad blockers.
On form submit, a Halo 2 ZK proof is generated using a Poseidon hash nullifier — proving attribution without revealing identity.
Proof verified and written to PostgreSQL. Nullifier stored in Redis. Any duplicate attempt is permanently and cryptographically rejected.
Your dashboard shows only cryptographically verified conversions. Compare against Google Ads to expose fraud and discrepancies.
Every major tracking failure mode addressed — without storing a single byte of PII.
Every nullifier is permanently stored. The same user converting twice gets cryptographically rejected — no configuration required.
Captures click IDs from all major ad platforms — each broken out separately in your dashboard.
Click IDs captured server-side from URL parameters the instant the user lands. No JavaScript needed at the click stage.
Email hash takes priority as the cross-device identifier. Same person on phone and laptop always resolves to the same cryptographic identity.
Emails and phone numbers are one-way hashed before entering the system. The attribution database contains nothing reversible.
Generate proofs in the browser via WebAssembly (maximum privacy) or server-side via API (maximum speed). Both modes hit the same verification backend.
