Summary for 2025-10: Completed a major wave of Predict feature work in MetaMask Mobile, improved feed reliability, and polished Market Details UI. Delivered end-to-end Predict UX enhancements, including an interactive Predict Details screen with charts, market data hooks, region-based gating, balance and unrealized PnL displays, claim flow, and support for resolved markets and positions. Expanded transaction activity views and multiple position handling in Predict, plus UI refinements and performance improvements. Polymarket feed got volume/liquidity filters, refined search, active-event prioritization by 24h volume, and targeted performance fixes. Market Details UI enhancements introduced a sticky tab bar and improved handling of resolved outcomes. A critical UX bug was fixed where the feed jumped to the top during fast scrolling, significantly improving stability. Overall impact: richer trading insights, faster data access, and a more reliable exploration experience, supported by React Native UI work, data-fetching hooks, and i18n coverage.

July 2025: Focused cleanup in MetaMask/metamask-extension by removing the experimental Remote Mode feature and all related code. This decommission reduces maintenance burden, lowers security risk from unenabled, in-progress functionality, and simplifies the codebase for future development and testing. No user-facing features were added this month; the change enhances stability and maintainability while preserving production readiness.
