DeepBookV3

URL: https://docs.sui.io/onchain-finance/deepbookv3/deepbook

DeepBookV3 is a next-generation decentralized central limit order book (CLOB) built on Sui. DeepBookV3 leverages Sui's parallel execution and low transaction fees to bring a highly performant, low-latency exchange on chain.

The latest version delivers new features including flash loans, governance, improved account abstraction, and enhancements to the existing matching engine. This version also introduces its own tokenomics with the DEEP token , which you can stake for additional benefits.

DeepBookV3 does not include an end-user interface for token trading. Rather, it offers built-in trading functionality that can support token trades from decentralized exchanges, wallets, or other apps. The available SDK abstracts away a lot of the complexities of interacting with the chain and building programmable transaction blocks, lowering the barrier of entry for active market making.

[!NOTE] The documentation refers to the DeepBook standard as "DeepBookV3" to avoid confusion with the recently deprecated version of DeepBook (DeepBookV2).

DeepBookV3 tokenomics

The DEEP token pays for trading fees on the exchange. Users can pay trading fees using DEEP tokens or input tokens, but owning, using, and staking DEEP continues to provide the most benefits to active DeepBookV3 traders on the Sui network.

As an example, governance determines the fee for paying in DEEP tokens, which is 20% lower than the fee for using input tokens.
