Aug 1, 2025

August 2025 monthly summary for drift-labs. Delivered major architecture and data-quality improvements across the dlob-server, keeper-bots-v2, and protocol-v2 with a strong focus on business value: price accuracy, data-source modernization, and robust trading simulations. Key initiatives included adopting Market Maker (MM) oracle data for perpetual markets, exposing MM data in API responses, and updating DLOB to use MM data with latest slot calculations to ensure accurate pricing. Completed Lazer (PYTH_LAZER) oracle migrations across protocol-v2 for perpetual and spot markets, updated pricing flows with enhanced type-safety, and introduced slot-aware pricing to improve vAMM quotes. Enhanced taker bot demonstrations with improved market index selection and trade-size distribution, and implemented sampling utilities for more realistic simulations. Fixed critical stability issues including a memory-leak fix in WhileValidTxSender and safeguards to skip delisted markets during Pyth crank processing. These changes collectively improve pricing accuracy, risk controls, and trading realism across core products.
