DeepBook is a decentralized central limit order book (CLOB) built on Sui. DeepBook leverages Sui's parallel execution and low transaction fees to bring a highly performant, low-latency exchange on chain.

DeepBook’s main competitive edge is that it is fully on-chain. All order routing, matching, and settling occur on-chain, delivering a trading venue that maximally leverages the benefits of programmability, interoperability, and composability. DeepBook v3 delivers a trading venue that is even more performant and that integrates seamlessly as the wholesale liquidity venue for the overall DeFi ecosystem.

As an on-chain order book, DeepBook delivers deeper and tighter liquidity, enabling better price execution for on-chain trading. For liquidity providers, in particular, DeepBook delivers more control over price orders than traditional Automatic Market Maker models and thus is better suited for sophisticated market makers. In addition, by virtue of being the premier wholesale liquidity venue of Sui DeFi, DeepBook is positioned as foundational liquidity to power broad range of financial services.
