DeepBook (DEEP) Tokenomie

DeepBook is a decentralized, permissionless, and on-chain central limit order book (CLOB) built on the Sui network. Designed as a "public good" for the ecosystem, it provides a high-performance liquidity layer for professional traders and DeFi protocols. The introduction of the DEEP token in version 3 (V3) establishes a native economic engine to incentivize liquidity and decentralize governance.

Issuance and Allocation Mechanism

The DEEP token is designed to align the interests of participants with the long-term success of the protocol. The total supply is distributed across four primary "buckets," with over two-thirds of the supply dedicated to the broader community.

Usage and Incentive Mechanism

The DEEP token serves as the primary utility and incentive asset within the DeepBook V3 ecosystem. Its model relies on four core "flows" to maintain equilibrium between takers and makers.

1. Trading Fees and Staking Benefits

DEEP is used to pay for trading fees on the exchange. While future upgrades may allow fees to be paid in input tokens, holding and staking DEEP provides significant advantages:

• Taker Incentives: Users who stake a predetermined amount of DEEP can reduce their trading fees by half. Fees can drop as low as 0.25 bps on stable pairs and 2.5 bps on volatile pairs once a minimum volume threshold is reached.
• Maker Rebates: Staked makers earn rebates based on the volume they generate. These incentives are designed to be countercyclical, meaning they are highest when total pool liquidity is lowest, encouraging providers to step in during periods of thin liquidity.

2. Governance

DEEP holders who stake their tokens gain governance rights over specific pool parameters. To prevent "governance capture" by large entities, the protocol employs a sub-linear (square root) voting power mechanism past a certain threshold. This ensures smaller participants have a voice against large institutional traders. Governance is currently limited to adjusting two fee-related parameters to prevent monopolistic pricing.

3. Anti-Wash Trading Protections

To ensure organic volume, DeepBook implements two primary defenses:

• Token Burning: If the fees collected in a pool during an epoch are greater than the incentives distributed, the residual DEEP tokens are burned.
• Incentive Caps: Once a liquidity threshold is met, maker incentives are set lower than the fees collected on the same trade, removing the financial motive for wash trading.

Locking Mechanism and Unlocking Time

The DeepBook protocol utilizes an epoch-based staking system to manage token locks and releases.

• Staking Requirement: Participants must stake the required number of DEEP tokens prior to the start of an epoch to be eligible for fee discounts or maker incentives during that period.
• Lock Duration: Stakes are committed for the duration of the epoch.
• Unlocking and Rollover: Once an epoch concludes, users have the choice to:
  1. Release the tokens back to their original wallets.
  2. Rollover the stake to the next epoch to continue receiving benefits.
• Pool Creation Fee: While not a lock, creating a new trading pool on DeepBook requires a one-time flat fee of 100 SUI.

The DEEP token launched on October 14, 2024, alongside the rollout of DeepBook V3. Specific long-term linear vesting schedules for core contributors and early backers were not detailed in the provided documentation beyond their total 28% allocation.
