Apr 1, 2026

April 2026 (DefiLlama/defillama-app) delivered two major unlocks-chart enhancements to improve data visibility and forecasting readability. Key features implemented: 1) Unlocks Chart TBD labeling and styling with refactored visuals, hatch patterns, dashed lines, reduced opacity, and a TBD end label for isTBD data (commit 173b2450cbfb235bd47d5faa6ee9d835ac17f01a). 2) Unlocks Chart Forecast styling and color mapping with distinct styling for forecast sections and improved color handling for chained reassignments (commit a0646f469d1bbe12a8f681507e02e939236d3b1b). These changes enhance interpretability of not-yet-available and projected data, enabling faster analytics and better business decisions. Overall impact includes clearer data storytelling in dashboards, improved user experience for analytics, and a solid foundation for consistent chart styling. Technologies/skills demonstrated include front-end charting and UI styling, handling isTBD/isForecast properties, hatch patterns, opacity adjustments, and robust color-mapping strategies.

March 2026 monthly summary for DefiLlama engineering. The month focused on delivering user-facing capabilities, expanding revenue visibility, and strengthening reliability across the ecosystem with a mix of feature work, data quality improvements, and performance optimizations across multiple repositories. Key features delivered include new breakdown capabilities for Bonk ecosystem (bonkSOL and bonk bot interactions), LetsBonk refill API fetch for balance management, and SPARK buybacks tracking, providing granular analytics and integration readiness for users and internal dashboards. Revenue accounting and SSR instrumentation were expanded across core protocols to improve profitability analysis and governance visibility (examples include Paxos Gold revenue, StarkNet L1 costs/revenue, Sunswap v2 revenue split, Meridian SSR, Velo revenue, Thorchain, Danogo, Hegic, and others). Major reliability and data-quality enhancements were implemented, including a logs-based replacement for Aethir API calls, added delays to Raydium to avoid rate limits, and improved error messaging for Kamino lending. Date handling fixes and spike/day data stability improvements reduced outages and improved data accuracy across feeds. Several data-ops improvements across Dune queries (Jupiter, Exa Card, Pumpswap, EulerSwap, Stader, etc) boosted query performance and timeliness.
