Worked on the input-output-hk/cardano-js-sdk repository to deliver a targeted dependency upgrade, focusing on enhancing the security and compatibility of the project. Upgraded the libsodium-wrappers-sumo package from version 0.7.5 to 0.7.10, addressing known vulnerabilities and improving performance across supported environments. Employed skills in dependency management and package management to ensure the upgrade process was robust and reproducible, utilizing JSON for precise configuration. Locked the libsodium version to enable consistent builds, reducing risk and supporting long-term stability. The work contributed to the overall reliability of the codebase by proactively managing dependencies and maintaining a secure development workflow.
