Sep 1, 2025September 2025 (2025-09) monthly summary for UMAprotocol/protocol: Highlights include three major feature deliveries that drive business value and reduce operational risk, along with progress across gas rebates, settlement orchestration, and notifier reliability. Gas rebates for 2025 (June–August) were implemented with updated calculations and data structures to grant rebates based on gas usage, enabling accurate retroactive incentives. Settlement bot enhancements unify settlement logic across Optimistic Oracle V1, V2, and Skinny into a single dispatcher and introduce a gas estimator to optimize settlement transactions, reducing costs and complexity. Polymarket notifier enhancements add configurable requesters, per-proposal idempotent notifications, deduplicated alerts, and deep links to UMA AI review results, improving reliability and user visibility. Minor note: no major bugs fixed this month. Overall impact: these changes improve incentive alignment, operational efficiency, and observability, while demonstrating strong cross-domain engineering on data structures, dispatcher design, and observability.
