DeepBook (DEEP): What It Is, Uses and Risks

DeepBook is the native central limit order book of the Sui blockchain. It is a shared trading layer in the base chain rather than an app with its own pool of liquidity, so any protocol on Sui can route orders through the same book. Each new integration adds depth that every other user can access. The project went live on Sui mainnet on 12 July 2023, was incubated by Mysten Labs and the Sui Foundation, and was rebuilt as DeepBook V3 in 2024. The protocol covers three primitives. Spot is the order book itself, with trades settling in a single Sui transaction. Margin adds leverage drawn from the same shared pool, with positions opening, executing and closing in one transaction. Predict, which brings binary options with continuous strikes and on-chain settlement, is currently on testnet, so it is not a live market for most users.

DEEP is the token associated with DeepBook. Public descriptions say it is used to pay trading fees and certain platform fees, such as the fee for creating a liquidity pool. Other listings describe it as a way to receive trading-fee discounts and market-maker rebates, and as a vote in on-chain governance. Community posts also mention staking DEEP for reduced trading fees, but that detail is not confirmed in the data available here, so treat it as unverified until you check the official documentation. Because Predict is still on testnet, do not assume DEEP has a live role in that product yet. The token's purpose is tied to the health of the order book: more volume and more integrations would mean more fee activity, though no fee figures are given here.

As of 2026-11-05, the data shows DEEP at about $0.0155 per token, with a market capitalisation of about $38.9 million and a fully diluted valuation of about $155.5 million. Its 24-hour trading volume was about $5.8 million, and it ranked 537th by market capitalisation. Over the prior seven days the price was down about 5 percent, and over the prior year it was down about 74 percent. The all-time high was about $0.341 on 2025-01-18, and the all-time low was about $0.0107 on 2024-10-14. The total and maximum supply are both 10 billion tokens, with about 2.5 billion in circulation, or roughly a quarter of the cap. The gap between market cap and fully diluted valuation reflects tokens that are not yet circulating. Ecosystem growth allocations are reported to vest linearly, meaning they are released in equal amounts over time. These figures change constantly, so check a live source before relying on them.

The data lists DEEP as issued on Sui. It is not listed as the native token of any blockchain, so it is best described as an asset built on Sui rather than the chain's own gas token. The protocol's launch date is 12 July 2023, but the token-specific launch field in the data is empty, so do not assume a separate token launch date. The DEEP token and the DeepBook protocol are related but are not the same thing. Using the protocol does not require holding the token in every case, and token holders' rights depend on the rules set by the protocol's governance, which should be read in the official documentation.

DEEP is a volatile asset. The gap between its all-time high and recent prices shows how sharply value can move, and a large share of the total supply is not yet circulating, which can add pressure as more tokens enter the market. Smart contract risk is real for any protocol on a blockchain, and the Predict product is still in testnet. Scam tokens often copy the names of real projects, so confirm the contract address against the official documentation before buying or moving funds. Store DEEP in a self-custody wallet that supports Sui and keep your recovery phrase offline. If you use any Predict or other gambling-style product in the future, you must be 18 or older, or 21 or older where required, and you should check that online gambling is legal where you live.
