Worked on the thirdweb-dev/js repository to enhance the reliability of Mode blockchain network identification within the SDK. Addressed a critical issue by correcting the Mode chain ID from 919 to 34443, ensuring that developers using the SDK interact with the correct network. The solution involved updating TypeScript code and documenting the change through a dedicated changeset, which was linked to relevant issues for traceability. Focused on blockchain development and SDK maintenance, the work improved network detection accuracy and prepared the fix for release. This targeted bug fix contributed to a more stable developer experience for Mode blockchain integrations.
