Developed a robust token configuration feature for the tonkeeper/ton-assets repository, focusing on scalable token management and improved onboarding. The work centered on introducing the Jekardos token by defining its metadata, including name, symbol, address, decimals, image, and social links, and standardizing configuration storage using YAML. This approach enhanced clarity and maintainability, reducing configuration drift across environments. By leveraging blockchain development skills and file management expertise, the developer enabled easier automation and auditing of token data. The transition to explicit YAML-based configuration established a clear, consistent foundation for future token additions and streamlined the onboarding process for new contributors.
