tZERO Group, Inc., a tokenization infrastructure leader, announced today that USDM1, a USD-denominated, fully secured sovereign bond issued natively on-chain by the Republic of the Marshall Islands, can now be held through tZERO Digital Asset Securities, LLC, an SEC-registered broker-dealer custodian of digital assets. This development enables institutional participants seeking regulated custody solutions for tokenized securities to securely hold USDM1 within a framework aligned with U.S. securities laws.
USDM1 is a natively issued, USD-denominated sovereign debt security backed 1:1 by pledged short-duration U.S. Treasury instruments. Each unit of USDM1 represents a direct interest in secured sovereign debt issued under New York law, structured in the style of a Brady bond, with an explicit customary waiver of sovereign immunity. Cleary Gottlieb advised the RMI as issuer’s counsel. The instrument combines the legal and structural protections of a traditional fixed income instrument with settlement and other efficiencies of tokenized assets, paying a coupon and potentially being treated as a financial instrument or cash equivalent.
“USDM1 introduces a new category of on-chain sovereign collateral that aligns with how institutions manage custody, financing, and balance sheet efficiency,” said Alan Konevsky, Chairman of the Board and Chief Executive Officer of tZERO. “Supporting USDM1 within tZERO’s custody solution reflects our focus on expanding regulated access to digital assets that can integrate directly into institutional workflows for cash and treasury management.”
USDM1 is currently issued and supported across multiple blockchain networks, including Stellar, Canton and Solana, providing flexibility for institutional participants. As collateral, it benefits from robust U.S. close-out netting protections and supports sovereign look-through to Level 1 HQLA under Basel standards. The addition of USDM1 to tZERO’s platform extends tZERO’s capabilities as a regulated infrastructure provider for tokenized securities, enabling institutions to hold sovereign, Treasury-backed digital asset securities within an SEC-registered qualified custodian, integrate on-chain assets into existing custody and operational frameworks, and access digital asset securities designed for compatibility with margin, financing, and collateral workflows.
Looking ahead, tZERO expects to explore broader infrastructure interoperability with USDM1 across its regulated ecosystem and broader DeFi use cases. This may include expanding availability of USDM1 to tZERO’s existing institutional client base, further integration with tZERO’s SEC- and FINRA-regulated broker-dealer capabilities, compatibility with tZERO’s clearing infrastructure and forthcoming derivatives framework, and API-level connectivity through tZERO Connect for institutional participants. Over time, the parties also expect to evaluate pathways for USDM1 to function as both a trading and funding instrument within regulated secondary market environments, including exploring access to liquidity through tZERO’s regulated alternative trading system.
This announcement reflects continued momentum in bridging traditional financial infrastructure with blockchain-based assets, as institutions increasingly seek regulated pathways to access tokenized securities and on-chain collateral.
