Worked on the erc7824/nitrolite repository to enhance frontend security, performance, and stability by upgrading core JavaScript dependencies. Focused on dependency management using npm, the work involved updating libraries such as viem, lucide-react, and tailwind-merge to their latest stable versions. These upgrades addressed security vulnerabilities, improved runtime efficiency, and ensured compatibility with modern frontend tooling. The process included implementing and validating Snyk-driven pull requests, with particular attention to multicall batching improvements and CSS consistency fixes. This approach reduced the vulnerability surface, improved UI reliability, and established clearer upgrade paths for future maintenance, supporting ongoing project stability and maintainability.
