Developed and integrated the ENNI protocol for Ethereum within the DefiLlama-Adapters repository, focusing on core DeFi metrics such as Total Value Locked, staking, and liquidity pool management. Leveraging JavaScript and blockchain development skills, the work introduced a CDP-related feature that enables more accurate TVL calculations and streamlined staking workflows for Ethereum-based assets. The implementation established foundational ENNI components, expanding Ethereum data coverage and supporting future cross-network protocol deployments. By enhancing smart contract interactions and data aggregation, this contribution improved the reliability and depth of DeFi analytics, setting the stage for broader feature expansion and more comprehensive protocol support.
