DeepBook V3 version has officially launched on the mainnet, and its token DEEP has also been officially released, marking an important development milestone for DeepBook in the Sui DeFi ecosystem. DEEP plays a core role in the Sui DeFi ecosystem, and DeepBook serves as the pillar of liquidity in Sui DeFi. The DEEP token is not only used to pay transaction fees, but the more users trade, the higher the fee discounts, incentivizing more participation. It can also be used for staking, where stakers can earn rewards by providing liquidity during periods of lower liquidity, ensuring other users receive smaller spreads and better trade executions.

The scalability of Sui means gas fees are stable and relatively low, which is beneficial for transactions on DeepBook. Sui's high-performance design, such as low latency and high-efficiency matching engines, provides strong liquidity for the entire Sui DeFi ecosystem. The launch of the DEEP token and the release of DeepBook V3 further enhance DeFi functionalities on the Sui network, including new application scenarios like perpetual futures, lending, and payments. These functionalities collectively enhance liquidity, making transactions on DeepBook more efficient. Therefore, the launch of DeepBook V3 and the release of the DEEP token not only enhance the depth and breadth of Sui DeFi but also provide new financial tools and opportunities for users and developers on the Sui network.
