May 1, 2025May 2025 highlights a major Emode program delivery and health/risk improvements in mrgn-ts, reinforcing borrowing flexibility, risk oversight, and developer experience. The release features end-to-end Emode integration across Bank, Config, and Store, plus new utilities and strategies, setting the foundation for safer, more configurable borrowing workflows. A health-system overhaul introduced action-level simulations, health pulse, health checks, and risk engine health monitoring, accompanied by stability fixes for builds and repay health scenarios. Data models were strengthened with extended bank objects and liability/collateral groupings to improve risk assessments, along with production URL support and UX enhancements for remaining accounts. Frontend performance and DX were boosted by Pyth cranking integration (frontend and cranker) and emode-related UI refinements, complemented by release hygiene and docs updates (gapless accounts).

Dec 1, 2024December 2024: Consolidated MRGN-TS capabilities by delivering a unified TradestoreV2, expanding yield/portfolio workflows, and strengthening data reliability and performance. Key features included a complete TradestoreV2 overhaul with home-page integration, arena refactor, admin updates, and final consolidation; a Yield Page with MRGN client helpers enabling end-to-end yield and portfolio work; SSR rendering for arena data powered by MarginFi API; and expanded onboarding with MarginFi account creation, new accounts flow, and separate account transactions. Additional improvements encompassed a Get Positions endpoint, admin panel enhancements, and integration of PYTH price feeds for pool creation. The codebase was cleaned (arena client removal, removal of console logs) and builds stabilized with merge-conflict resolution and SSR toggle via environment variable. These efforts delivered faster data access, more reliable trading and portfolio management, stronger onboarding, and a maintainable foundation for future growth.
