What is Exchange OS#

Exchange OS is builder-first trading infrastructure built on X Layer. It provides a shared, high-performance stack for launching and operating on-chain spot and perpetual markets, including matching, margin, liquidation, settlement, and risk controls.

It combines protocol-level asset security and transparent settlement with a purpose-built execution environment for professional trading.

Why Exchange OS#

On-chain markets are often fragmented across separate accounts, liquidity, execution systems, and risk frameworks. Builders must repeatedly recreate exchange infrastructure, while users manage capital and exposure across disconnected venues.

Exchange OS provides shared infrastructure, unified market access, and reusable trading primitives so new markets can launch faster and capital can be used more efficiently.
