Developed the Hikari Fee and Revenue Adapter for the DefiLlama/dimension-adapters repository, delivering a new financial visibility layer for DeFi protocols. Focused on backend and blockchain development using TypeScript, the work enabled accurate on-chain calculation and exposure of fees and revenue from staking and liquidity pools. Implemented event-driven data ingestion for staking and fee events, refining decimal normalization and revenue calculation logic to ensure stable, auditable metrics. Addressed formatting and methodology alignment during pull request iterations, enhancing the quality of the data pipeline. The resulting adapter improved financial reporting transparency for users, holders, and governance by supporting reliable revenue attribution.
