During a three-month period, Vinh Loc contributed to the streamingfast/substreams and DefiLlama/defillama-server repositories, focusing on backend development and configuration management using Go and JSON. He enhanced substreams by introducing granular network configuration, updating structures and validation logic to support multi-network deployments and safer rollouts. Loc also improved schema management by refactoring commit generation logic, increasing reliability and maintainability of schema updates within CI pipelines. On defillama-server, he addressed a token mapping issue for liquidBeraETH on CoinGecko, ensuring accurate data representation. His work demonstrated depth in API integration, data mapping, and robust version control practices across complex systems.

In January 2026, DefiLlama/defillama-server delivered a critical bug fix to ensure accurate liquidBeraETH token mapping on CoinGecko, reinforcing data integrity for Ethereum assets and improving user trust in token listings. The fix aligns token references with Ethereum and prevents misrepresentation across analytics feeds, implemented with minimal risk and validated against the mapping logic and external reference data.
