Worked on the ethereum/remix-project repository to address a reliability issue affecting Etherscan transaction URL generation in the terminal. Investigated and resolved a bug where an incorrect ',false' suffix was appended to transaction hashes, resulting in broken links. Conducted root cause analysis that identified a mismatch between the broadcastTx event payload and the listener’s destructuring logic in blockchain.tsx. Implemented a fix in TypeScript to ensure event arguments were passed separately, aligning with the listener’s expectations and restoring correct URL formation. Validated the solution against the URL generation logic, improving user experience and reducing support overhead. Demonstrated skills in TypeScript and full stack development.
