During November 2025, Lbdong2013 enhanced the lifinance/customized-token-list repository by adding the XDOG token to the XLAYER token list, expanding token availability for users. The work involved updating the token configuration, including renaming the XLAYER.json file to XLY.json to maintain consistent naming conventions. Lbdong2013 applied blockchain development and token integration skills, working primarily with JSON to ensure seamless integration of the new asset. The feature addressed the need for broader token support without introducing bugs, reflecting a focused and well-scoped engineering effort. The contribution demonstrated depth in configuration management and attention to detail in blockchain token list maintenance.
