New York, 27 August: Virtu Financial, M1X Global and Tradeweb today announced the completion of the first fully onchain repo transaction in which the securities leg was a sovereign digital bond. Executed on the Canton network, every element of the transaction – securities delivery, cash leg and return – settled atomically onchain. The transaction is the first known instance of a natively issued sovereign digital security functioning as collateral in a repo executed through a major institutional electronic trading venue without prime broker intermediation.
The Virtu repo was executed bilaterally on the Tradeweb platform between regulated institutional counterparties. It mapped structurally to a conventional sovereign-collateralized repo but utilized a digitally native issuance benefiting from ledger-based collateral mobility. The confirmation included a complete repo cycle – execution and repurchase – in under 10 minutes, a structure that is operationally impossible under T+1 settlement infrastructure. Where earlier onchain repo demonstrations relied on digital cash instruments in place of sovereign securities collateral, or on securities collateral held off-chain, this transaction was the first to combine natively issued sovereign collateral with fully onchain atomic settlement across both legs.
USDM1, the securities leg of the transaction, is a sovereign bond issued natively onchain by the Republic of the Marshall Islands, structured under New York law in the style of a fully collateralized Brady bond. It is backed 1:1 by short-dated US Treasuries held in bankruptcy-remote custody. Holders benefit from a first-priority perfected security interest in 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 standardized approach, it delivers materially lower risk-weighted asset consumption than corporate payment stablecoins, tokenized money market fund shares or unrated digital asset exposures. Unlike digital cash instruments, USDM1 pays a coupon when used as margin or collateral. The instrument is available through Tradeweb with institutional custody through Anchorage, BitGo and tZERO. It is also supported by FDIC-insured Bank of Guam.
Atomic settlement on the Canton Network eliminates the intraday balance sheet inflation and settlement exposure that arises under T+1 infrastructure and increases effective collateral velocity, enabling same-day reuse that is not possible in traditional repo markets.
USDM1 was structured under advice of Cleary Gottlieb as issuer’s counsel, with a New York law indenture, an explicit customary waiver of sovereign immunity, and documentation designed to support title-transfer repo, collateral substitution, and reuse within institutional frameworks under standard ISDA and GMRA documentation.
Participant Commentary
Jordan Goldman, President and COO, M1X Global: “Derivatives and secured financing markets have been waiting for collateral that works across institutional and digital rails simultaneously. USDM1 is a secured sovereign digital bond – not a stablecoin, not a tokenized fund, not a CBDC. It combines the legal framework and capital treatment institutional counterparties require with 24/7 settlement. This transaction demonstrates for the first time what onchain sovereign collateral looks like in production.”
Dan Eckstein, Head of Rates Sales, Virtu Financial: “Virtu’s business is built on providing liquidity efficiently across every market we operate in. Capital efficiency is not an abstract concept for us – it shows up directly in our ability to deploy working capital and serve clients. USDM1 addresses collateral constraints that have limited onchain capital markets and prevented them from reaching institutional scale. We are committed to helping build the foundational infrastructure this market requires.”
Liz Kirby, Head of Market Structure, Tradeweb: “We see tokenization as an important next step in the evolution of electronic trading and market infrastructure. The completion of this transaction demonstrates how digitally native sovereign collateral and atomic settlement can enhance collateral capital efficiency and modernize repo workflows, all while maintaining the institutional standards market participants have come to expect. We are pleased to collaborate with other industry leaders on developing and advancing practical solutions that support the continued evolution of institutional markets.”
