Description

DeepBook positions itself as 'Where Sui Finance Starts,' offering three core primitives — Spot, Margin, and Predict — combined into one composable financial stack. For builders, DeepBook provides plug-and-play liquidity, margin logic, and settlement infrastructure so teams can focus on their product rather than the underlying plumbing. For traders, DeepBook offers a single, deep order book that powers the entire Sui ecosystem, delivering tighter spreads and deeper markets without fragmentation across venues. The platform reports significant scale, including over 13.75B in total volume, 279.8K total users, and 27.35M in 24h volume, with 125.7M DEEP burnt from trading fees. Security is emphasized as a core focus, with the platform being audited and protected by a bug bounty program. Various teams in the Sui ecosystem build on top of DeepBook's financial stack to create DeFi products.
