Deep Dive
1. Mainnet Upgrade v3.1 (August 2025)
Overview: Enabled unrestricted pool creation via new Move modules while integrating Mysten Labs' MVR (Multi-Version Registry) for cross-chain asset resolution.
The upgrade introduced 65 commits including MVR metadata objects for decentralized package management and kiosk-compatible asset storage. Developers can now deploy pools without whitelisting by paying 500 DEEP (reduced from 1,000 DEEP).
What this means: This is bullish for DEEP because it lowers barriers for new liquidity pools while improving interoperability with Sui-based DeFi apps. Traders gain access to more markets, potentially increasing protocol revenue.

2. Indexer Overhaul (July 2025)
Overview: Replaced MongoDB with PostgreSQL in the DeepBook Indexer to handle 10,000+ events/sec, tracking fills, cancellations, and governance votes.
The Rust-based system now processes Sui checkpoints 12% faster via concurrent pipelines. New tables track maker/taker fees in both base assets and DEEP tokens, addressing prior gaps in rebate calculations.
What this means: This is neutral for DEEP as it primarily benefits developers and institutional users needing granular historical data. However, improved analytics could attract sophisticated trading strategies.

3. Fee Structure Update (June 2025)
Overview: Implemented EIP-4512 introducing variable DEEP burns (10-30% of protocol fees) based on 30-day revenue averages.
A new balance_to_burn
field was added to the Move contract's History struct, with burns triggered weekly via keeper bots. The change followed community voting where 71% of staked DEEP supported deflationary mechanics.
What this means: This is bullish for DEEP because reduced supply could counter inflation from the 7-year token unlock schedule. However, traders may see slightly higher effective fees during low-revenue periods.

Conclusion
DeepBook's codebase advances toward decentralized market infrastructure with MVR integration and permissionless features, while fee/burn mechanisms align long-term incentives. How will Sui's planned Q4 2025 zkRollup integration further impact DeepBook's latency and cross-chain capabilities?
