Virtu Financial, M1X Global, and Tradeweb have completed what they describe as the first fully on-chain repo transaction in which the securities leg was a natively issued sovereign digital bond. Executed on Canton Network, every element of the transaction, including securities delivery, the cash leg, and the return, settled atomically on-chain. The full repo cycle, execution and repurchase, completed in under 10 minutes.
The transaction was executed bilaterally on the Tradeweb platform between regulated institutional counterparties, without prime broker intermediation. It mapped structurally to a conventional sovereign-collateralised repo but used digitally native securities as collateral rather than assets held off-chain or digital cash instruments standing in for sovereign collateral. The firms say it is the first known instance of a natively issued sovereign digital security functioning as repo collateral through a major institutional electronic trading venue.
The securities leg was USDM1, a sovereign bond issued natively on-chain by the Republic of the Marshall Islands, structured under New York law in the style of a fully collateralised Brady bond. USDM1 is backed 1:1 by short-dated US Treasuries held in a bankruptcy-remote structure, with holders maintaining a first-priority perfected security interest in that collateral under UCC Articles 8 and 9. The instrument is classified as a UCC Article 8 investment security, is eligible for inclusion in ISDA and GMRA close-out netting sets, and supports sovereign look-through to Level 1 HQLA. Under Basel 3.1's standardised approach, it carries materially lower risk-weighted asset consumption than corporate payment stablecoins, tokenised money market fund shares, or unrated digital asset exposures. Unlike digital cash instruments, USDM1 pays a coupon when used as margin or collateral.
Atomic settlement on Canton eliminates the intraday balance sheet inflation and settlement exposure that arises under T+1 infrastructure, while increasing collateral velocity to enable same-day reuse that is not possible in traditional repo markets.
"USDM1 is a secured sovereign digital bond, not a stablecoin, not a tokenised fund, not a CBDC," said Jordan Goldman, President and COO of M1X Global. "It combines the legal framework and capital treatment institutional counterparties require with 24/7 settlement."
Dan Eckstein, Head of Rates Sales at Virtu Financial, framed the transaction around capital efficiency. "USDM1 addresses collateral constraints that have limited onchain capital markets and prevented them from reaching institutional scale," he said.
Liz Kirby, Head of Market Structure at Tradeweb, described the result as a practical demonstration of what digitally native sovereign collateral and atomic settlement can deliver. "We are pleased to collaborate with other industry leaders on developing and advancing practical solutions that support the continued evolution of institutional markets," she said.
USDM1 is available through Tradeweb with institutional custody through Anchorage, BitGo, and tZERO, and is supported by FDIC-insured Bank of Guam. Cleary Gottlieb served as issuer's counsel on the instrument's structuring under New York law.
