Kieran automated the token data management process for the pillarwallet/x repository by implementing a system that refreshes the tokens.json file without modifying application logic. Leveraging automation tools and data governance practices, Kieran ensured that token list updates are traceable and auditable, with explicit commit messages and automated provenance. The work focused on maintaining data integrity and reducing manual intervention, using JavaScript and JSON for data handling and Git for version control. This approach established a reliable foundation for future token-aware features, enabling faster updates and minimizing risk, though the scope was limited to data updates without direct code or bug fixes.
