Order book transactions finally achieve the speed and low transaction fees required for linking. It was created to provide a centrally restricted order book and close matching and settlement fees at a cent or less.
With the combination of SUI parallel execution and optimized matching engines, DeepBook is expected to bring exchange-level pricing into the deep liquidity library of the Defi protocol. Let’s get a deeper look at what Deep Book is, how it works in the SUI ecosystem, how it fits pictures, and the benefits it brings to your portfolio.
What is Sui’s deep book?
DeepBook is a chain order matching protocol. Deepbook is a high-performance local liquidity layer SUI Blockchain. Unlike the decentralized exchange and automated market manufacturer DEX, the Deepbook protocol uses a more traditional one Central Restricted Order Book (Clob)which helps create stricter spreads and more familiar trading mechanisms.
Orders are stored on the SUI as objects, meaning they benefit from the blockchain’s parallel execution model, which has a lower latency and is usually terminated.
because Deep Book Embedded in network level, wallets, aggregators and DEFI protocols can be inserted directly into their order books, sharing deep liquidity rather than spreading over isolated pools.
This architecture positions Deepbook as a base service, just like Uniswap on Ethereum, providing Sui developers with an off-the-shelf exchange engine without rebuilding core matching logic.
The benefits of deep books
- Deep liquidity: All DAPPs on SUI can purchase the same order book and centralize the volume instead of dividing it into multiple DEXs.
- Better price execution: A Clob model can achieve limiting orders, complex marketing and minimal slips and falls, and is favored by professional traders.
- High throughput, low fees: SUI is based on the object design process and orders are conducted in parallel, resulting in microsecond matches and negligible gas costs.
- The synthetic nature of the builder: Developers can integrate deep books on top of their liquidity through simple APIs, tiered loans, leveraged trading or derivatives.
- Transparent chain datone: Each order, cancellation and fill are recorded in Sui’s ledger, providing auditability and reducing information asymmetry compared to chain books.
How does a Deepbook work?
Deepbook is a centrally restricted order book on the chain, living locally on Sui. It matches discrete bids compared to the constant product curve used by automated market makers and is asked like traditional exchanges, so traders get execution of price time priority and certainty.
Two mechanisms keep liquidity deep and spread. First, everyone starts with a standard fee, but if the takeover puts the smallest deep token in the pool and then trades in the volume threshold over the period, its marginal fee will automatically be cut in half. Therefore, actively streaming to Deep Books, the more transactions you have, because the cost drops.
Next, when the total liquidity of the pool is thin and phased out as liquidity increases, the manufacturer of the equity then receives a proportion of token rebates. This counter-periodic curve encourages liquidity during quiet times and avoids paying when the book is already healthy.
Both allowances rely on share-based participation, and without a minimum in-depth deposit, the wallet pays full charges without receiving a manufacturer’s reward, thus aligning the incentives between the serious liquidity provider and the agreement. During the period, any unrecycled fees are not recycled as manufacturers’ incentives are permanently burned, so washing transactions become uneconomical while tokens remain deflationary.
Stakers have the right to recessed voting, charge belts and possession thresholds for each pool, which give smaller holders meaningful weight while also preventing whales from withdrawing monopoly rents. In fact, this unique fee discount, adaptive discount, stock gated access, fee burning and pool level governance all curate an automatic balanced market where professional market dealers, Defi protocols and high-frequency traders can all obtain wholesale liquidity without centralization.
Deep Book Ecosystem
Aftermath Finance All-On-One Hub, Kriyadex’s AMM-Plus-Limit orders, CETUS Concentrated Liquid DEX, FlowX Trading Portal, Hop Cottregator, Turbos Finance Extryforkity DEX and 7K Contregator Route Outer Route Emptioner all insert shared orders directly.
Deep Book Token (Deep)
Utilities
Deep Stoken is a local token for the DeepBook protocol and adds fuel to the economic layer. Manufacturers’ incentives earn deep rebates for liquidity providers, while earners receive discounted transaction fees.
Token distribution and release schedule
The fixed supply depth is 10 billion, 61.6% allocated to community air energy operations, 10% initial air conditioning, 7.5% allocated to early contributors, 10% for Mysten Labs, 10.9% and 10% for liquid partners. Emissions gradually declined over four years, with monthly attributable contributors and quarterly unlocked, which are limited to milestones in chain volume.

How to buy deep?
Deep can be traded on the DeepBook itself through Deep/USDC pairs and a summary SUI DEX router. Bridge USDC to SUI, connect to a compatible wallet, and place restrictions or market orders on any deep book front end. It’s as easy as 1, 2, and 3.
in conclusion
DeepBook brings exchange-grade order trade to SUI without sacrificing decentralization. By embedding a fast debris in the network layer, it can provide deep liquidity, minimal slip and transparent price discovery.
For traders, DeepBook means low trading fees and tight order spreads. For builders, this means a near-inherent plug-in liquidity backbone used to manage trading activities. In short, DeepBook has a solid position to be at the heart of the Sui Defi ecosystem.
