Payments that settle on-chain — and stay confidential.

Shielded transfers: amounts and counterparties stay private; validity and solvency stay provable on demand.

Payments · Privacy · A confidential-payments team · under NDA
In plain terms

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.

The challenge

They needed on-chain settlement without broadcasting every amount and counterparty to the world — confidentiality for the business, provability for the auditor.

What we built
  • 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
Outcome

Counterparties and amounts stay private by default; validity and solvency stay provable on demand — non-custodial throughout.

How it’s wired

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.

1Shielded balance

Balances held confidentially, spendable only by the owner's key.

2ZK proof of validity

A zero-knowledge proof shows a transfer is valid without revealing it.

3Private transfer

Amounts and counterparties stay off the public ledger.

4Selective disclosure

Prove a single payment to an auditor without exposing the rest.

How we build it
  • 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 stack we built

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.

01

Shielded transfer contracts

Amounts and counterparties stay off the public ledger.

02

Zero-knowledge proofs

Validity is proven to the network without revealing the transfer.

03

Selective disclosure

Prove a single payment to an auditor — and nothing else.

What we hardened

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.

The risk

Competitors read your flows on a public chain.

How we guard it

Balances and transfers are shielded by default.

The risk

An auditor needs proof, but you can't expose everything.

How we guard it

Selective disclosure reveals exactly one record, on demand.

The risk

An invalid transfer slips through unseen.

How we guard it

A zero-knowledge proof of validity gates every transfer.

Handover

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.
