Order Book DEX

Order

An order book decentralized exchange (DEX) replicates the functionality of traditional order books found on centralized exchanges, but operates on a blockchain network, typically utilizing smart contracts. These DEXs facilitate peer-to-peer trading of cryptocurrencies and, increasingly, derivatives like options, by matching buy and sell orders directly. The core mechanism involves users submitting orders specifying price and quantity, which are then aggregated and displayed in an order book format, enabling price discovery and efficient trade execution. This contrasts with automated market maker (AMM) models, which rely on liquidity pools and algorithms rather than explicit order matching.
