Payments that settle on-chain — and stay confidential.
Shielded transfers: amounts and counterparties stay private; validity and solvency stay provable on demand.
Public blockchains show everyone every amount and every counterparty — fine for a hobby, fatal for a business. This system keeps balances and payments private using zero-knowledge proofs: the network can confirm a payment is valid without seeing what it is. When an auditor needs to check one transaction, you prove just that one — and nothing else.
They needed on-chain settlement without broadcasting every amount and counterparty to the world — confidentiality for the business, provability for the auditor.
- 01Shielded transfer contracts with zero-knowledge proofs of validity
- 02A privacy vault that holds balances confidentially, spendable only by the owner
- 03Selective disclosure — prove a payment to an auditor without revealing the rest
Counterparties and amounts stay private by default; validity and solvency stay provable on demand — non-custodial throughout.
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.
Balances held confidentially, spendable only by the owner's key.
A zero-knowledge proof shows a transfer is valid without revealing it.
Amounts and counterparties stay off the public ledger.
Prove a single payment to an auditor without exposing the rest.
- 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 | |
|---|---|---|
| Visibility | Everything public | Private by default |
| Validity | Must be visible to verify | Proven with zero-knowledge |
| Audit | All or nothing | Selective disclosure |
| Custody | Varies | Non-custodial |
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.
Shielded transfer contracts
Amounts and counterparties stay off the public ledger.
Zero-knowledge proofs
Validity is proven to the network without revealing the transfer.
Selective disclosure
Prove a single payment to an auditor — and nothing else.
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.
Competitors read your flows on a public chain.
Balances and transfers are shielded by default.
An auditor needs proof, but you can't expose everything.
Selective disclosure reveals exactly one record, on demand.
An invalid transfer slips through unseen.
A zero-knowledge proof of validity gates every transfer.
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.
“Private to the world, provable to our auditor. Both, finally.”
