# Overview

**Fair Math Payments** is a **flexible privacy framework** for existing on‑chain financial systems.

It introduces a modular architecture that enables developers and organizations to **add privacy controls to their current infrastructure** — wallets, treasury systems, payroll solutions, or DeFi applications — **without requiring**:

* deployment of a new blockchain,
* migration to custom tokens, or
* changes to wallet ownership models.

The framework integrates directly with **existing account infrastructures** (Safe is the first supported integration) and adds a **privacy account layer** on top of standard on‑chain accounts, enabling selective encryption of balances and transaction data.

#### Core Properties

* **Non‑disruptive:** preserves existing wallets, assets, and operational flows.
* **Modular:** privacy features can be activated selectively (e.g. per token, per operation, or per user group).
* **Customizable:** allows fine‑grained privacy policies, from minimal amount‑only encryption to fully confidential transfers.
* **Auditable:** designed with support for accounting, reporting, and regulatory compliance.
