During a three-month period, Crow004 developed and enhanced DeFi analytics features across the DefiLlama-Adapters and dimension-adapters repositories. They built a Musical Chairs TVL adapter for Arbitrum, expanding on-chain coverage by calculating ETH balances, including player stakes and commissions, using JavaScript and Node.js. Crow004 also updated product messaging in DefiLlama’s server codebase with TypeScript to improve Web3 accessibility for users. In February, they delivered multi-chain TVL reporting and a revenue tracking adapter, refining TVL metrics and enabling end-to-end revenue attribution.
