Developed and delivered a new Painmon Finance TVL Adapter for the DefiLlama-Adapters repository, enabling accurate calculation of total value locked for ERC4626 vault-based protocols. The work involved implementing the ERC4626 standard within a modular adapter architecture, ensuring seamless integration with existing data pipelines. Using Node.js and JavaScript, the developer focused on backend development to expand protocol coverage and improve data accuracy for Painmon Finance metrics. The adapter broadened TVL visibility, supporting more reliable dashboards and informed business decisions. Collaborative development practices were demonstrated through co-authored commits, establishing a foundation for future ERC4626-compatible protocol integrations within the platform.
