During October 2025, Black Key enhanced data coverage in the DefiLlama/dimension-adapters repository by expanding the GMGN fee accounts address scope. They adjusted SQL queries to use an IN clause for addresses and a NOT IN clause for trader_id, incorporating nine additional addresses to improve the completeness of fee account data retrieval. This backend development work, implemented in TypeScript and SQL, enabled more accurate fee analytics and revenue reporting for partners. The targeted change was delivered through a focused commit with clear documentation, reflecting a precise approach to database management and integration while minimizing disruption to the existing codebase.
