Santai developed the Yei Finance Fees Dashboard within the DefiLlama/dimension-adapters repository, focusing on enhancing financial analytics for DeFi applications. The work involved implementing data-fetching logic using TypeScript and GraphQL to calculate daily fees and revenue by comparing reserve data across consecutive days. By integrating APIs and leveraging robust data processing techniques, Santai enabled clear visibility into Yei Finance’s financial performance, supporting data-driven decision-making and trend analysis. The feature addressed the need for accurate, real-time insights into platform revenue, demonstrating depth in both API integration and DeFi analytics. The project was completed over one month with a targeted, feature-driven approach.
