Contributed to the MystenLabs/ts-sdks repository by developing Move Type and Struct Tag Validation Utilities, enhancing the SDK’s validation layer for Move types and struct tags. Focused on implementing isValidStructTag and isValidMoveIdentifier functions, the work leveraged TypeScript and advanced regex techniques to ensure accurate and robust validation. Internal utilities were added to support consistent validation across the codebase, directly addressing integration reliability and traceability to issue #827. Emphasized unit testing and validation best practices, resulting in safer SDK surfaces and clearer type correctness. No major bugs were fixed during this period, with efforts concentrated on feature delivery and quality improvements.
