# 4.2.3 YRF Module | Yield Revenue Feedback

> "It does not intervene during panic, but quietly executes during healthy conditions. YRF is the silent stabilizer of currency trust."

In the ARK protocol, YRF functions as the "Central Revenue Repurchase Bureau" within the overall economic system.

It is neither a price defense unit like RBS, nor an expansion engine like EM, but rather the core module for smooth internal deflation of the system.

When the protocol generates stable revenue, the YRF module automatically uses a portion of the treasury income to repurchase ARK from the market and immediately burn it—following predetermined rules, proportions, and frequencies—to achieve three objectives:

* Supply compression
* Rhythm stabilization
* Enhancement of scarcity
