Ethereum Institutional confirmed on July 30, 2026 that Ethereum will be supported on Open USD from launch day, positioning the network as a core settlement layer for the stablecoin's business-focused infrastructure.

More than 140 companies have joined the Open Standard initiative, including Visa, Mastercard, Stripe, BlackRock, and BNY. The breadth of the coalition—spanning card networks, merchant acquirers, asset managers, and custody banks—distinguishes the project from existing stablecoin arrangements that are typically issued and controlled by a single entity. Under the proposed model, the majority of reserve income generated by Open USD would be distributed to the businesses that help deploy and use the stablecoin, rather than being retained solely by a single issuing entity.

Why Ethereum Matters to Open USD

Ethereum provides payment companies with a shared settlement network that is not controlled by any single participant. This characteristic is particularly relevant when major financial players such as Visa, Mastercard, and Stripe are expected to operate on the same infrastructure. Each participant can independently verify the asset and its settlement rules without depending on a proprietary system managed by a competitor.

Ethereum also contributes established liquidity, mature infrastructure, and broad familiarity among institutional market participants. Additional supported networks can then handle transfers where lower transaction fees or faster execution times are prioritized.

Ethereum Institutional announced the integration via X:

Breaking: Open USD will launch on @ethereum on day one.

Over 140 businesses, including Visa, Mastercard, Stripe, BlackRock and BNY. All reserve earnings flow to the partners that grow it.

A shared asset needs neutral ground.

Built for Business Applications

Open USD is being designed primarily for corporate settlement, cross-border treasury operations, payment processing, and institutional liquidity management, rather than retail trading. Consumers may use the stablecoin indirectly without interacting with it directly. A merchant, payroll platform, or remittance service could settle transactions through Open USD on the backend while customers continue to pay and receive funds in their local currencies.

The business model also differs from established stablecoins such as USDT and USDC, which collectively account for the overwhelming majority of stablecoin market capitalization. Participating companies that assist in distributing Open USD are expected to receive a portion of the reserve earnings. This structure could provide exchanges, payment firms, and fintech platforms with a financial incentive to integrate the stablecoin, though ordinary token holders would not automatically be entitled to any yield.

Ethereum Fees and Multichain Strategy

Ethereum transaction costs remain a practical consideration, particularly for treasury desks, payment processors, and other companies handling high transaction volumes. These firms can mitigate expenses by batching transfers, settling larger amounts less frequently, or routing smaller transactions through alternative supported networks with lower fees.

Ethereum is more likely to serve high-value settlement and liquidity needs rather than individual point-of-sale transactions. Its inclusion at launch provides Open USD with access to a significant institutional market. Support across multiple networks expands the stablecoin's potential applications in payments, trading, and treasury operations without requiring all activity to flow through the Ethereum mainnet. The project's trajectory will depend on factors including the timing and scope of its launch, which additional networks are added, and how participating companies integrate the stablecoin into existing payment and treasury workflows.
