During January 2026, KryptoDev7 developed a SOL Fees and Revenue Calculator Adapter for the COAL Protocol within the DefiLlama/dimension-adapters repository. This adapter enables precise calculation and distribution of SOL fees and revenues to multiple stakeholders, addressing the need for transparent revenue attribution in COAL-integrated data feeds. KryptoDev7 focused on seamless integration with the existing adapter framework, enhancing maintainability and stability without introducing major bugs. The work leveraged TypeScript for backend development, along with API integration and Solidity expertise, resulting in a robust solution that ensures consistent data flows and supports accurate financial reporting for the COAL Protocol ecosystem.
