Developed comprehensive token management capabilities for the hiero-ledger/hiero-sdk-java repository, focusing on expanding the Hiero SDK TCK to support full token lifecycle governance. Leveraging Java, gRPC, and expertise in API design, the work introduced robust token operations such as fee schedule updates, freeze and unfreeze, association and disassociation, pause and unpause, KYC management, minting, and burning. The implementation included refactoring parameter parsing and adding new parameter and response classes to streamline these operations. This feature enhanced transaction management and improved test coverage, enabling more reliable end-to-end validation of tokenomics workflows within the SDK, with minor stability improvements included.
