Buy & Swap DeepBook Protocol (DEEP)

One order book for a whole ecosystem

DeepBook's official site describes it as the place where Sui finance starts. Its pitch to traders is direct: trade on Sui's deepest liquidity, because one order book powers the entire ecosystem — tighter spreads and deeper markets without jumping between fragmented venues.

The pitch to builders is the other half of the same idea. New projects get shared liquidity from day one, with composable primitives that handle the hard parts — margin logic, settlement — so the team can focus on the product while DeepBook handles the plumbing.

This is the classic order-book model rather than an automated market maker: buyers and sellers place orders at prices they choose, and the book matches them. Putting that book fully on-chain means the matching rules, the order queue and the settlement all live in open smart contracts on Sui, rather than on a server someone operates behind the scenes.^{[1], [2], [3]}

Three primitives, one stack

The site summarises the product as three primitives: Spot, Margin and Predict. These share liquidity and form one composable financial stack, so everything needed to go from idea to launch sits in the same place.

Composability is the key word. Because the primitives share one stack, the site argues, builders can combine them into financial products that do not exist yet. The site showcases teams that skipped building their own infrastructure and launched on DeepBook's stack instead.

The result, in the project's telling, is a stronger DeFi ecosystem on Sui: deeper markets and better execution for traders, and a faster path from idea to launch for builders. The site is currently gathering a waitlist for the DeepBook app, signalling that a dedicated trading interface is the next step.^{[4], [5], [6]}

Reported traction

DeepBook's site publishes its own headline figures: 13.75 billion in total volume, 279.8 thousand total users, 27.35 million in 24-hour volume, and 125.7 million DEEP burnt from trading fees at the time of review.

These are the project's self-reported numbers, recorded here as such rather than independently verified. The site also states the protocol is audited, bounty-protected and fully transparent, describing its security as battle-tested.^{[7], [8]}

Where DEEP fits

DEEP is the token at the centre of the protocol's fee and incentive system. The official token page describes three roles. First, payment: DEEP is used to pay trading fees and pool creation fees, giving the exchange a single native currency for a unified trading experience.

Second, liquidity: DEEP enhances trading liquidity by offering rebates to market makers during low-liquidity periods and volume discounts to liquidity takers. Third, the burn: the site reports DEEP being burnt from trading fees, tying token supply to actual exchange activity. Together, the site says, these mechanisms align the interests of all participants in the ecosystem.

The rebate design is worth pausing on. Market makers — the participants who keep orders resting on the book so others can trade instantly — are most needed exactly when liquidity is thin. Paying them rebates during those periods is a direct incentive to keep quoting when it is least profitable, which is how the protocol tries to keep spreads tight through quiet markets as well as busy ones.^{[9], [10], [11], [12]}

How the margin and prediction markets develop

DeepBook presents Spot, Margin and Predict as one stack, but the relative activity and rollout state of each primitive is not broken down on the official pages reviewed. That detail is UNKNOWN from official sources.

It is not predicted here.^[4]
