Leifu Chen developed and refactored cross-chain data adapters for the DefiLlama/dimension-adapters and DefiLlama-Adapters repositories, focusing on unified TVL, volume, and revenue reporting for DeFi protocols such as Overtime and Thales. Using TypeScript, JavaScript, and Solidity, Leifu centralized token and contract configurations, modularized adapters for maintainability, and implemented event-driven data aggregation to improve accuracy and traceability. The work included dynamic chain module creation, revenue and LP fee tracking, and config-driven methodologies that streamlined onboarding of new protocols. These engineering efforts established consistent, reliable analytics across multiple blockchains, enhancing investor visibility and supporting robust, maintainable data infrastructure.

In August 2025, focused on delivering accurate market metrics and revenue visibility in DefiLlama/dimension-adapters by refactoring the Thales Options Adapter. The work improved volume calculations for speed and chained markets and added revenue tracking from SafeBoxFeePaid events and LP fee tracking from SafeBoxSharePaid events, providing a comprehensive view of market activity and revenue streams. This resulted in more reliable data for decision-making and forecasting, and stronger data integrity for performance reporting.
