# Virtual Market Maker #### 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 --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
