**Starknet Privacy** is a protocol for private asset transfers on Starknet: sender, receiver, and amounts are hidden from outside observers, while validity is enforced with client-side zero-knowledge proofs (Stwo / Cairo). A compliance layer allows an auditing entity to trace activity when legally required, without exposing unrelated users.

## What these docs are for

These docs describe the **protocol**—notes, channels, discovery, compliance,
transaction ordering, and security considerations—so developers, partners,
and enterprises can understand how Starknet Privacy works.

- **Live on mainnet:** the privacy pool contract is deployed at
[`0x0403…812a`](https://voyager.online/contract/0x040337b1af3c663e86e333bab5a4b28da8d4652a15a69beee2b677776ffe812a).
The contract source is readable on Voyager.
- **SDK not yet public:** the TypeScript SDK and proving stack are not open
sourced yet. When they ship, operational guides (install, quickstart,
end-to-end usage) will be added here.

## What you get

| Property | Summary |
| -------- | ------- |
| --- | --- |
| **Private transfers** | Sender, receiver, and amount hidden from observers; transacting parties and authorized auditors can see details. |
| **Compliance** | Designated auditor can selectively trace history under legitimate regulatory request. |
| **Efficient discovery** | Recipients find notes in time scaling with *their* activity, not total pool activity. |
| **Efficient discovery** | Recipients find notes in time scaling with _their_ activity, not total pool activity. |
| **Multi-asset** | One pool supports multiple token types. |
| **DeFi** | Anonymous interaction with existing Starknet DeFi via open notes and atomic flows. |
| **Account abstraction** | Spend authority uses your Starknet account (multisig, smart wallet, etc.). |
