Planet Daily News: Fidelity Investments has applied to the U.S. securities regulator to register its Ethereum-based U.S. Treasury fund "OnChain", planned to be launched on May 30th, to track its $80 million Fidelity Digital Government Fund (FYHXX) transactions. Although the records on the blockchain will not serve as the official ownership ledger, Fidelity will reconcile it daily. Currently, the blockchain Treasury market size has reached $4.78 billion, with BlackRock's BUIDL fund leading at $1.46 billion. Fidelity stated that OnChain might be expanded to other blockchains in the future. (Cointelegraph)
