DeepBook is a fully on-chain decentralized exchange (DEX) protocol built on the Sui blockchain, utilizing a Central Limit Order Book (CLOB) model. Designed as the shared liquidity infrastructure of the Sui ecosystem, DeepBook offers fast, transparent, and efficient trading experiences similar to centralized exchanges (CEX). By leveraging Sui’s high throughput, parallel execution, and low gas fees, DeepBook enables low-slippage and high-speed order execution. The native token, DEEP, powers staking, governance, and fee-sharing mechanisms within the ecosystem. Integrated across various DeFi platforms and supported by strategic partners, DeepBook is positioned as the core on-chain liquidity layer for next-generation DeFi.
