DeepBook is a next-generation 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.


The latest development iteration of DeepBook is version 3 (DeepBookV3). DeebBookV3 is currently available in both Devnet and Testnet. DeepBookV2 is the current Mainnet iteration of DeepBook.

DeepBookV3 is scheduled to replace DeepBookV2 on Mainnet in the second half of 2024.

DeepBook is open for community development. You can use the Sui Improvement Proposals (SIPs) process to suggest changes to make DeepBook better.
