Open USD will launch on Ethereum from its first day of operation as part of a broader multichain rollout that also includes Solana, Base, Stellar and Polygon.
The July 30 announcement from Ethereum Institutional confirms the network’s inclusion and highlights its role in the stablecoin’s business-focused settlement infrastructure.
As we previously reported, more than 140 companies have joined Open Standard, including Visa, Mastercard, Stripe, BlackRock and BNY. Under the proposed model, most reserve income would be shared with businesses that distribute and use the stablecoin instead of remaining entirely with a single issuer.
Why Ethereum Matters to Open USD
Ethereum offers payment companies a shared settlement network without placing the underlying ledger under the control of any one participant.
That matters when companies such as Visa, Mastercard and Stripe are expected to use the same infrastructure. Each can verify the asset and its settlement rules without relying on a private system operated by a direct competitor.
Ethereum also brings established liquidity, mature infrastructure and familiarity among institutional market participants. Other supported networks can then handle transfers where lower fees or faster execution matter more.
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.

Open USD Is Being Built for Business Use
Open USD is being positioned mainly for corporate settlement, cross-border treasury activity, payment processors and institutional liquidity rather than retail trading.
Consumers may therefore use it without interacting with the stablecoin directly. A merchant, payroll platform or remittance service could settle through Open USD behind the scenes while customers continue paying and receiving funds in local currency.
Its business model is also different from those of USDT and USDC. Participating companies that help distribute Open USD are expected to receive a share of the reserve earnings. That could give exchanges, payment firms and fintech platforms a financial reason to integrate it, although ordinary token holders are not automatically entitled to yield.
Ethereum Fees Will Matter Most to Businesses
Ethereum transaction costs remain a practical consideration, especially for treasury desks, payment processors and other companies handling large volumes.
These firms can reduce costs by batching transfers, settling larger amounts less frequently or routing smaller transactions through cheaper supported networks. Ethereum is more likely to serve high-value settlement and liquidity needs than individual purchases at checkout.
Its inclusion from day one gives Open USD access to a major institutional market. Support for several networks broadens the stablecoin’s potential use across payments, trading and treasury operations without requiring all activity to pass through Ethereum mainnet.

It started in 2016 with Bitcoin. Like most people at the time, he didn’t fully understand it – so he kept digging. Blockchain, tokenomics, the projects, the cycles. That curiosity never stopped, and eventually pulled him into traditional markets too: equities, commodities, macro. Not because he left crypto behind, but because you can’t properly understand one without the other.
What drives him is straightforward: he wants to know why something is happening, not just that it’s happening. Most market coverage stops at the headline – price up, price down, here’s a chart. Alex finds that kind of reporting actively unhelpful. If you walk away from an article without understanding the mechanism behind the move, what did you actually learn?
He holds a degree in Tourism from New Bulgarian University – not the most obvious path into financial markets, but markets have a way of pulling in people who are simply too curious to stay out. He has authored over 200 in-depth analyses and more than 10,000 articles across crypto and traditional finance. He still thinks every day in markets teaches him something new. That’s probably why he hasn’t stopped.
