Worked on improving installation state reliability for the worldcoin/minikit-js repository, focusing on a critical bug fix that addressed how the MiniKit provider determines if the kit is installed. The solution involved validating the actual result of the install command rather than relying on a default true value, ensuring that the isInstalled state accurately reflects the real installation status. By initializing isInstalled as undefined until confirmation, the update reduced false positives and improved reliability for downstream applications. This work utilized frontend development skills with React, leveraging JavaScript and TypeScript to enhance state management and strengthen the overall installation flow.
