In January 2026, John Downing developed and integrated a new Quai Network Daily Revenue Adapter for the DefiLlama/dimension-adapters repository. He focused on backend development using TypeScript and API integration to fetch daily revenue data from Quai Network’s merged mining activities. This adapter expanded the platform’s revenue coverage and enabled more accurate analytics and dashboards by providing granular, daily data. John maintained clean architecture and thorough documentation, ensuring the codebase remained extensible for future adapters. His work addressed the need for improved revenue attribution and cross-chain activity tracking, demonstrating depth in both technical implementation and understanding of data integration practices.
