Virtu Financial, M1X Global, and Tradeweb have completed an on-chain repurchase transaction using the digital sovereign bond USDM1 issued by the Marshall Islands as collateral, with all settlements completed on the Canton Network within 10 minutes. The parties stated that this is the first case combining native-issued sovereign collateral with fully on-chain atomic settlement.

USDM1 is a dollar-denominated sovereign bond issued on-chain by the Republic of the Marshall Islands, backed 1:1 by short-term U.S. Treasury securities, which continues to pay interest during the collateral period and is structured as a fully collateralized sovereign debt instrument under New York law. The bond is offered through the Tradeweb platform, with custodial services provided by Anchorage Digital, BitGo, and tZERO.

Canton is a blockchain network designed for institutional finance, equipped with privacy and permission management features. Prior to this transaction, Tradeweb facilitated the real-time transfer of tokenized U.S. Treasury securities from Franklin Templeton to Virtu Financial on Canton in July. Since August, FalconX and Interstice have launched a cross-chain exchange engine connecting Canton with Ethereum, Solana, and Robinhood Chain, and World Liberty Financial has also natively issued the USD1 stablecoin on Canton.
