Each USYC token represents a share in Hashnote International Short Duration Yield Fund Ltd.

The HashKey Earn Channel has established an RWA product offering covers multiple asset classes, including tokenized money market funds, precious metals, fixed-income assets, stablecoins and equity assets (certain products are available to professional investors only). The listing of USYC further expands HashKey Exchange’s RWA product offering, and strengthens the platform’s capabilities in tokenized asset distribution and institutional on-chain asset services.
