BitGo Adds Institutional Custody and T+0 Settlement for USDM1, the World's First Natively Issued Onchain Sovereign Bond

Each quarter, the Republic of the Marshall Islands sends $200 to eligible citizens across more than 1,200 Pacific islands, many of them beyond the reach of any correspondent bank. Since November 2025, those disbursements have traveled via USDM1, a sovereign bond issued natively on blockchain. On July 17, BitGo announced it would add institutional custody and T+0 off-exchange settlement for USDM1, moving the instrument from government UBI payments into the collateral stack of institutional counterparties.

What Is USDM1? The Marshall Islands Onchain Sovereign Bond Explained

USDM1 is a USD-denominated secured sovereign bond issued by the Republic of the Marshall Islands (RMI). It is structured as a fully collateralized Brady bond under New York law, with a sovereign immunity waiver, and each token is backed 1:1 by short-duration U.S. Treasuries held in a bankruptcy-remote account. Value accrues daily, with enforceable par redemption.

What distinguishes it structurally from most tokenized debt products is that it was not migrated from a legacy register onto a blockchain. As the Marshall Islands Ministry of Finance whitepaper states: "USDM1 is a digital, fully collateralized, USD-denominated sovereign bond issued directly on-chain. It is not a wrapped instrument." The blockchain is the legal register of record.

USDM1 launched in January 2026 and currently lives on three networks simultaneously. According to RWA.xyz data, total circulating supply is approximately 1.25 million USDM1: roughly 1.05 million tokens on Stellar, 207,000 on Ethereum, and approximately 469 tokens on Solana via the Token-2022 standard. The three-chain structure reflects each network's positioning: Stellar for cross-border payment corridors, Ethereum for institutional DeFi, and Solana for throughput and low transaction costs.

Marshall Islands ENRA: Funding Universal Basic Income Across 1,200 Islands

The government application embedded in USDM1 is what separates it from most institutional fixed-income instruments. The Republic's ENRA program (its 20-year nationwide Universal Basic Income initiative) is funded through the U.S.-capitalized Compact Trust Fund created to compensate the Marshall Islands for decades of nuclear testing on its atolls. Citizens receive their quarterly disbursements via Lomalo, a mobile app powered by Crossmint wallets on Stellar. For residents of remote atolls where no bank branch exists, the system replaces what were once physical cash deliveries by government transport vessels.

The legal framework is what makes USDM1 credible as sovereign debt rather than a blockchain experiment. Cleary Gottlieb served as issuer's counsel on the issuance structure, with Guidepost Solutions building the compliance framework and Anchorage Digital Bank providing the existing crypto custody. The IMF has separately cautioned the Marshall Islands about the program's complexity relative to the country's regulatory capacity. Its current deployment remains early-stage in scale.

BitGo Adds Segregated Custody and Go Network T+0 Off-Exchange Settlement

BitGo Bank & Trust, regulated by the Office of the Comptroller of the Currency as a digital asset trust bank, will offer two services on top of what already exists: segregated custody with offline key management, and the ability to use USDM1 as collateral for off-exchange settlement through the BitGo Go Network.

The Go Network product is what makes the collateral use case meaningful for institutions. Counterparties can trade against connected venues without moving USDM1 out of BitGo's regulated custody. Settlement happens in the same session (T+0 rather than the T+1 or T+2 standard in fixed-income), around the clock, 24/7.

"Sovereign collateral with Treasury backing, built to fit how institutions already operate," BitGo CEO Mike Belshe said in the July 17 announcement. The structure is designed to keep assets off exchange and in regulated custody, reducing the counterparty and commingling risk that institutional compliance teams flag when collateral transfers onto a trading venue. BitGo carries up to $250 million in insurance for assets held in its regulated custody.

The Go Network has expanded steadily through 2026. OKX announced in April it would integrate for U.S. institutional clients. STS Digital joined in January for derivatives and spot settlement. Adding a sovereign bond alongside crypto assets broadens the range of instruments the network's settlement rails can handle.

Marshall Islands Minister of Finance Hon. David Paul said he "truly appreciates BitGo's partnership and is proud to see this infrastructure put to work," per the July 17 announcement.

Potential Basel III High-Quality Liquid Asset Classification

One structural feature of USDM1 goes beyond collateral mechanics. The instrument is built with properties that could qualify it as a Level 1 High-Quality Liquid Asset under Basel III-equivalent frameworks, a classification normally reserved for sovereign debt held in regulated bank custody. If that classification holds across relevant jurisdictions, it positions USDM1 not just as tradeable collateral but as a potential component of bank liquidity portfolios. The USDM1 product page notes this as a structural design target; BitGo's announcement does not state that the classification has been confirmed in any specific jurisdiction.

At $1.27 million in total asset value across 465 holders, up 31.7% in 30 days per RWA.xyz, the figures reflect where the product is in its lifecycle. Monthly transfer volume of approximately $10 million per RWA.xyz suggests active institutional testing rather than scaled deployment.

Solana as One of Three Native Issuance Chains

USDM1's Solana deployment was established at launch, not added later. All three chain deployments are native, born on each respective network rather than bridged, which matters for the risk profile institutional compliance teams evaluate: bridged assets carry additional smart contract dependency on the bridge layer.

Three days before this announcement, Fenics, OpenYield, and Tradeweb joined Pyth Network as fixed income data publishers, bringing institutional Treasury and government bond pricing on-chain on Solana. The two developments are not formally connected, but they arrive in the same week and address the same underlying gap: institutional fixed-income instruments and their pricing infrastructure, building on the same network.

Solana's RWA market cap reached $2.01 billion in Q1 2026, a 43% increase quarter-over-quarter, per RWA.xyz network data. Baillie Gifford's BAGEY, a UK FCA-regulated tokenized bond fund that launched natively on Solana and Ethereum in June 2026, established an earlier precedent for institutional fixed income choosing Solana as a native deployment chain. USDM1 is a different structure, a sovereign bond rather than a fund, but the pattern is the same: when institutions now issue fixed-income instruments natively on blockchain, Solana is regularly one of the chains in the answer.

For the Solana ecosystem, the native Token-2022 deployment means USDM1 is in principle accessible to protocols that can accept sovereign-backed instruments as collateral. Between Anchorage Digital's existing custody and BitGo's incoming integration, the custody layer for USDM1 on Solana now has two regulated options.
