## Exchange Matching Engines

Exchange Matching Engines are the core software systems that execute trades by matching buy and sell orders based on predefined rules. They are the final arbiter of order priority, usually following a price-time priority algorithm.

The performance of these engines is critical to the functionality of an exchange, as they must handle thousands of transactions per second with minimal latency. They ensure that orders are filled fairly and that the state of the order book remains consistent across the platform.

In decentralized exchanges, the matching engine may be replaced by a smart contract that functions as an automated market maker. The design of these engines impacts how orders are processed, especially during high volatility events when the system is under heavy load.

A robust engine is the foundation of trust for any trading venue, ensuring that every participant receives equal treatment under the rules.
