Worked on the MetaMask/metamask-extension repository, delivering features that enhanced permission management, security, and user experience. Focused on Gator Permissions, implemented a cache-first loading strategy and aligned APIs with evolving standards, using JavaScript, TypeScript, and React. Introduced granular permission types, per-request validation, and new RPC methods to support finer-grained user consent and ERC20 token revocation. Upgraded dependencies, improved UI clarity, and strengthened end-to-end testing to ensure robust workflows. Addressed security by validating DApp origins and enhancing trust signal middleware. The work emphasized performance optimization, state management, and automation testing, resulting in more resilient, maintainable, and secure extension functionality.
