During March 2026, Matthix73 contributed to the lifinance/customized-token-list repository by expanding the token catalog with a new PUPI token entry, including comprehensive metadata such as address, chain ID, symbol, decimals, name, and logo. Working primarily with JSON and leveraging skills in blockchain integration and token standards, Matthix73 focused on enhancing data completeness and consistency within the token list. The work laid the foundation for future asset onboarding by updating the LNA.json schema and ensuring accurate data management. No bug fixes were required, as all changes were additive, reflecting a focused approach to structured data enrichment and schema evolution.
