How Does DeepBook V3 Work?
DeepBook V3 is the native on-chain central limit orderbook (CLOB) for Sui, enabling limit and market orders with institutional-grade performance. The DEEP token provides governance and fee discounts for stakers. With ~$15M TVL and deep Sui integration, it serves as core trading infrastructure for the network.

On-chain CLOB leveraging Sui's parallel execution for high-performance order matching
CLOB design leveraging fast L1
5.1.1
DEEP token governance for protocol upgrades, fee structures, staking requirements
10B fixed supply, 7-year vesting
2.1.2
Tiered trading fees with DEEP staker discounts (0.25 bps staked takers on stables)
Maker rebates and taker discounts
3.1.1
Pro-rata DEEP staking rewards providing fee discounts proportional to stake
Aligns token holders with active traders
1.2.1
Linear vesting with 1-year cliff for core contributors (28.43%), 3-year total
25% at TGE, rest over 7 years
4.3.2
NovelFlash loans integrated into the orderbook for arbitrage and complex strategies
Flash loans on CLOB is novel — enables atomic cross-DEX arbitrage
How the Pieces Interact
Large DEEP stakers get lower fees, creating two-tier market where unstaked traders face adverse selection
Flash loans enable atomic arbitrage against resting orders — makers may widen spreads to protect against flash loan MEV
Governance could adjust fees to benefit large stakers at expense of smaller traders
Large unlocks could depress DEEP price, reducing staking attractiveness
What Could Go Wrong
- On-chain CLOB on Sui creates latency advantages for co-located validators and sophisticated market makers over retail users
- Single-chain dependency on Sui means all orderbook liquidity is tied to Sui network health
- DEEP token staking for fee discounts may concentrate trading power among large stakers
MEV Extraction Driving Market Makers Away
ModerateTrigger: MEV bots systematically extract value from resting orders via flash loans and latency
- 1.MEV bots use flash loans and speed to pick off stale orders — Market makers face adverse selection losses
- 2.Makers widen spreads or withdraw — Liquidity depth deteriorates
- 3.Traders migrate to AMM DEXs — Volume declines
- 4.DEEP value drops — Fee discount weakens
- 5.CLOB becomes niche — Fails broad adoption
