Compliance checks without the data lake.
Prove a user is eligible — KYC'd, not sanctioned, of age — without storing or exposing their personal data.
Verifying customers normally means collecting and storing passports and addresses — which turns you into a target every hacker and regulator watches. With zero-knowledge proofs, the user proves they are eligible (old enough, not sanctioned, in the right country) without you ever seeing or storing the underlying documents. There is no data lake to leak.
They were obligated to verify users but didn't want to become a honeypot of personal data that every regulator and attacker would come for.
- 01Zero-knowledge eligibility proofs — verify a claim without seeing the data behind it
- 02Attestations issued once and reusable across the platform
- 03Nothing personal stored on-chain or by us — the user keeps their data
Eligibility is provable on every transaction; the personal data never leaves the user, so there is no lake to leak.
The architecture, end to end.
Each box is a primitive we wrote and you own — legible all the way down, no black-box vendor in the path. Value flows left to right.
The user proves a claim — age, jurisdiction, sanctions-clear — once.
Eligibility is verified without ever seeing the data behind it.
No personal data on-chain or with us — the user keeps it.
A reusable attestation proves eligibility on every transaction.
- On-chain where enforcement matters; in your infrastructure where operation matters.
- Non-custodial by default — keys and funds stay with their owner.
- Audited line by line, then handed over: repository, runbook, and proofs.
The shape of the change.
One figure, measured honestly. The rest of the gains are in the table below.
Legacy vs the system we built.
| The legacy way | With Govart | |
|---|---|---|
| Data stored | Full personal records | None |
| Breach risk | A honeypot | Nothing to steal |
| Verification | Re-done per service | Reusable attestation |
| Proof | Trust the checker | Zero-knowledge, provable |
Primitives, not black boxes.
Each layer is code you own and can read — written in-house, audited, and handed over. No rented dependency in the path of your money.
Zero-knowledge eligibility
Prove age, jurisdiction and sanctions-clear without seeing the documents.
Reusable attestations
Verify once, then reuse across every service on the platform.
No data store
Nothing personal is held on-chain or by you — there's no lake to leak.
Built as if it’ll be attacked.
In crypto, one mistake is terminal. We threat-model before we build — here’s what could go wrong, and what stops it.
A breach exposes a lake of personal data.
There is no lake — nothing personal is ever stored.
KYC is re-collected for every single service.
One reusable attestation covers them all.
You're trusting a checker's word.
Eligibility is provable with a zero-knowledge proof.
Yours at the end. All of it.
The engagement ends — that’s the point. What stays is everything you need to run and extend the system without us.
The repository
Every contract and service, commented and documented — nothing withheld, no black box.
Audit reports
Internal review plus an independent third-party audit, your engineers reading along.
The runbook
How to operate, monitor, upgrade and recover — written for your team, not ours.
Keys & training
Full control transferred, and your engineers walked through it until it's theirs.
“We verify who's eligible without ever holding their data.”
