Worked on the berachain/metadata repository to implement the deprecation of the USDa token by removing its entry from the mainnet.json configuration. This change streamlined the configuration management process, reduced the maintenance burden, and aligned the system with the project's deprecation strategy. The approach focused on disciplined change management, utilizing JSON for configuration updates and Git for version control and traceability, referencing issue #383 throughout the process. By isolating the update to a single configuration file, the work minimized potential downstream impact and improved overall reliability, demonstrating careful attention to data management and robust configuration handling within the codebase.
