Open USD: How a 140-Company Consortium Is Building an Open Stablecoin Rail

An Open Rail Built Together

On June 30, 2026, Open Standard announced Open USD (OUSD), a dollar-pegged stablecoin backed by a consortium of more than 140 companies. The participant list spans both mainstream finance and technology, including Stripe, Visa, Mastercard, BlackRock, Coinbase, BNY, Standard Chartered, Google, and Shopify. What makes Open USD notable is less the peg itself and more its structure: it is designed as shared open payments infrastructure that many organizations help operate and benefit from together, rather than a product owned by a single issuer.

A stablecoin is a token engineered to hold a steady value, in this case one U.S. dollar, by holding reserves against every unit in circulation. The mechanism is straightforward. When a participant mints OUSD, dollars flow into reserves; when they redeem, reserves flow back out. The design intent is that the token remains fully backed at all times, which is what gives a stablecoin its utility as a settlement medium.

No Fees, No Caps, Shared Yield

Three design choices define how Open USD behaves in practice. First, it charges no mint or redeem fees. Participants can move in and out of the token without paying a spread on conversion, which lowers the friction of using it as a working balance. Second, there are no volume caps, so the rail is built to scale with demand rather than throttle it.

The third choice is the most structurally interesting. Reserves that back a dollar stablecoin typically sit in short-term, interest-bearing instruments. Open USD returns nearly all of that reserve interest to participants after a small management fee. In a conventional model, the issuer keeps the yield. Here, the economics are pooled and redistributed to the companies using the rail. That aligns incentives across the consortium: the more the shared infrastructure is used, the more value flows back to the participants who use it.

This is what distinguishes cooperative infrastructure from a standard commercial product. The value generated by the reserves is treated as a shared resource rather than a private margin, which is a meaningful design decision for a network meant to be used broadly.

Solana First, More Chains to Follow

Native issuance launches on Solana, a high-throughput layer-1 blockchain well suited to low-cost, high-frequency payment activity. The choice fits the use case: a payments rail benefits from fast finality and low per-transaction cost, and Solana provides both.

Open Standard has signaled that additional layer-1 networks, including Tempo, will follow later in 2026. From an architectural standpoint, multi-chain issuance matters because it lets the same dollar token operate natively across different environments rather than being confined to one. That broadens where OUSD can settle and integrate.

Reading the Design

Stepping back, the analytical takeaway is about coordination. Assembling 140-plus companies across finance and technology around a single open rail is itself a signal that these organizations see value in shared, neutral infrastructure for dollar payments. The fee-free, cap-free, yield-sharing model is a deliberate attempt to make participation attractive and the economics collaborative.

Whether measured by breadth of participants or by the openness of its structure, Open USD represents an effort to build a common payments layer jointly rather than competitively. The launch on Solana is the first concrete step, and the planned expansion to additional chains suggests the consortium intends this to be broad, shared groundwork rather than a single-network experiment. As always, the details of adoption will unfold over time, but the design itself is a clear statement of intent toward open, cooperative financial infrastructure.
