# VMMCore

VRC-9

#### **Abstract**

The Virtual Market Maker (VMM) has a triple mandate as the common ZKSC counterparty, default LP vault, and exchange market maker. Due to liveness constraints mandated by ZKSCs, participants self-validate states with the VMM. Furthermore, the VMM intakes escrow from liquidity providers which it utilizes to ensure liquid markets and stable liquidations. It distributes all excess state proportionally to liquidity providers.

#### **Features**

* Solvency
* Sustainable Yield
* Continuous network uptime
