Worked on the LIT-Protocol/js-sdk repository to enhance security for the 0G Mainnet by upgrading its RPC communication from HTTP to HTTPS. This front-end development effort focused on reinforcing data-in-transit security and reducing the risk of man-in-the-middle attacks, while maintaining compatibility by preserving the existing block explorer URL. The change was implemented in TypeScript with a single, well-documented commit, ensuring minimal disruption to existing integrations. By aligning with TLS best practices, the work improved the security posture for production-grade RPC access and demonstrated careful attention to code quality, compatibility, and the reliability of mainnet interactions within the JavaScript SDK.
