zerohash Makes OUSD Live Across Its Network

Crypto infrastructure firm zerohash has switched on Open USD (OUSD), a dollar stablecoin, for every business that uses its services. “OUSD is now live on zerohash,” the company posted on X on 27 October, after announcing it in a release on GlobeNewswire earlier that day.

The stablecoin is “available today to all partners zerohash powers across all products”, the company says. It is supported on four blockchains: Base, Ethereum, Solana and Tempo.

In brief

zerohash has made the Open USD (OUSD) stablecoin available to every business it powers.
It runs on Base, Ethereum, Solana and Tempo.
zerohash’s own documents show it is not available to New York users, and the firm provides no US liquidity for it.

What zerohash does

zerohash sits behind other companies’ apps. Banks, brokers, card firms and fintechs plug into its systems to offer crypto, stablecoins and tokenised assets without holding the licences and running the plumbing themselves. It says it operates “regulated entities in 51 U.S. jurisdictions” and has licences in the EU, Latin America, Australia, New Zealand and Bermuda. TSN has covered one example of how this works: Interactive Brokers’ Ethereum staking service, which zerohash provides.

The firm says its partners “today include industry leaders including Marqeta and Visa Direct”. Neither company has said it will use OUSD. The release lists them only as zerohash partners.

For those partners, the release says, OUSD can be used for “treasury, account funding, payouts and payins”. zerohash also links OUSD to “more than 15 stablecoins across approximately 25 chains”, so a business can move between OUSD and other stablecoins through the same connection.

“We integrated OUSD because it’s a stablecoin built for payments by the networks that already move the world’s money,” said Mark Daly, zerohash’s chief business officer. Partners can turn it on through their existing zerohash link, he said, “without building additional infrastructure”.

What OUSD is

OUSD comes from Open Standard, a group that launched the coin on 30 September. According to its launch post, “OUSD is issued by Bridge, a Stripe company, with reserves held at BlackRock, Lead Bank and other large financial institutions.” Businesses can create and redeem OUSD at “a 1:1 USD conversion rate, at no cost”. Open Standard says it has more than 200 partners, who “earn rewards proportional to the supply and activity they drive”.

At launch, Open Standard named BVNK, Stripe, the Visa Stablecoin Platform and Coinbase as ways in. OUSD has since appeared in other payment products TSN has covered, including Stripe and Plasma’s planned stablecoin cards and Mastercard and BVNK’s Global Money Platform.

New York is the gap in zerohash’s OUSD rollout

The headline says “all partners”, but the small print narrows it. zerohash’s release says support for stablecoins, “including OUSD, may be subject to regulatory approval in certain jurisdictions, including in New York.” Its developer documentation is more direct. In the table for zerohash’s US business, all four versions of OUSD are marked “No” under “Support in NY”, which the page defines as whether the asset is available to New York participants. USDC on Ethereum, by contrast, is marked “Yes”.

The same table marks OUSD “No” under “Liquidity”, defined as whether zerohash provides liquidity for buying and selling the asset. In other words, zerohash will hold and move OUSD for US partners, but it is not itself acting as a buyer and seller of the coin there. For a payments product, that may matter less than it would for trading, since Open Standard’s launch post says businesses can create and redeem OUSD at 1:1 through its integration partners.

New York matters because many financial firms are based there, and its regulator licenses crypto activity separately from federal rules. zerohash itself holds New York licences for virtual currency business, so the gap is about the asset, not the firm. Federal rules are also still settling: the OCC’s final GENIUS Act rule for stablecoin issuers only takes effect in January 2027.

The bigger point is distribution. A new stablecoin needs places where businesses can use it. By plugging OUSD into a layer that many card and payout firms already use, Open Standard gets reach without each firm building its own integration. Whether that turns into real payment volume is not yet known, as neither company gave usage figures.

What happens next

OUSD is live for zerohash partners now, outside New York. The release does not say when New York approval might come. zerohash accounts are “not subject to FDIC or SIPC protections”, the company notes.
