# Cashmere Privacy

> Privacy-preserving, issuer-backed stablecoin transfers.

import { Card, CardGroup, Callout, Steps } from 'mintlify';

## Summary

Cashmere Privacy extends the bridge infrastructure with zero-knowledge proofs and policy tooling so organisations can settle stablecoin flows without exposing counterparties, amounts, or routing metadata.

<Callout type="warning">
  **Status:** Research and prototyping. Targeting public testnet in 2026.
</Callout>

## Design Objectives

<CardGroup cols={2}>
  <Card title="Confidential Settlement" icon="eye-slash">
    Hide key transaction details on-chain while maintaining verifiable correctness.
  </Card>

  <Card title="Omnichain Coverage" icon="globe">
    Deliver the same privacy guarantees across all Cashmere-supported networks.
  </Card>

  <Card title="Compliance Optionality" icon="shield-halved">
    Provide selective disclosure and audit trails for regulated participants.
  </Card>

  <Card title="CCTP / USDT0 Compatibility" icon="link">
    Integrate natively with issuer messaging standards for zero-slippage mobility.
  </Card>
</CardGroup>

## Technical Approach

<Steps>
  <Step title="Proof Construction">
    Users generate zk proofs attesting to valid balances and transfer intent without revealing sensitive data.
  </Step>

  <Step title="Source Validation">
    Proofs are verified prior to burning assets on the origin chain, ensuring compliance with Cashmere policies.
  </Step>

  <Step title="Private Minting">
    Destination mints occur without exposing origin addresses or amounts. Optional audit hooks capture encrypted metadata.
  </Step>
</Steps>

## Privacy Modes

* **Standard** – hides amount and recipient while retaining origin metadata for operational purposes.
* **Advanced** – shields origin, amount, and recipient; intended for treasury or enterprise flows.
* **Compliance** – allows designated auditors to decrypt transaction metadata via selective disclosure.

## Roadmap Highlights

<CardGroup cols={2}>
  <Card title="Phase 1" icon="microscope">
    Cryptographic design, threat modelling, and issuer alignment (current).
  </Card>

  <Card title="Phase 2" icon="flask">
    Closed testnet with limited privacy features and compliance APIs.
  </Card>

  <Card title="Phase 3" icon="rocket">
    Mainnet deployment with full privacy/compliance tooling.
  </Card>

  <Card title="Phase 4" icon="chart-line">
    Ongoing enhancements, partner integrations, and open-source release cadence.
  </Card>
</CardGroup>

## Integration Guidance

* Privacy flows reuse the Gas API for fee/signature generation.
* Builders can choose between public and private transfer flows within the same contract suite.
* Selective disclosure keys and audit workflows will be exposed via enterprise APIs.
