According to ChainCatcher, a document submitted to the U.S. Securities and Exchange Commission (SEC) this Friday reveals that Fidelity has applied to register an "OnChain" share class for its tokenized U.S. dollar money market fund, Fidelity Treasury Digital Fund (FYHXX), which was launched at the end of last year and holds cash and U.S. Treasury securities.

Based on the related document information, the "OnChain" class of the FYHXX fund currently uses the Ethereum network and may expand to other blockchains in the future. This registration is subject to regulatory approval and is expected to take effect on May 30.
