DeepBook

DeepBook is the native central limit order book built into the base layer of the Sui blockchain, meaning it functions as shared infrastructure rather than a standalone application. It is designed so that any protocol or application built on Sui can route trades through the same shared book, deepening liquidity collectively rather than fragmenting it across competing venues. The project addresses the problem of isolated liquidity pools that is common in decentralised finance, and it is intended primarily for developers and protocols building on Sui rather than end users directly.

DeepBook settles spot trades atomically inside a single Sui transaction without any off-chain component, using the order book as a shared on-chain primitive. A margin layer draws from the same shared liquidity pool, allowing leveraged positions to open, execute and close within one transaction and without an off-chain sequencer. The DEEP token is used within the system for governance and, based on the categories assigned to this asset, for fee-related functions within the protocol.

Over the trailing 30 days the protocol recorded fees of 1,727.83 USD, and annualising that figure produces an estimate of 21,021.93 USD. Of the 30-day fees, 742.72 USD was retained as protocol revenue, reflecting a take rate of roughly 42.99 percent over that same 30-day period, with the remaining 985.11 USD going to the supply side. The 24-hour fee figure was 134.00 USD and the 7-day figure was 660.66 USD, indicating that fee activity can vary meaningfully from one short window to the next.
