zerohash, an onchain infrastructure provider, announced that Open USD ("OUSD") is now live across its network. The stablecoin, introduced by Open Standard, is available to all partners zerohash powers across all of its products, meaningfully expanding the distribution of the token.

For stablecoins — blockchain tokens designed to hold a steady value against a reference asset such as the U.S. dollar — distribution is often the deciding factor in real-world use: a token only matters for payments if platforms, chains and endpoints can actually transact with it. By switching OUSD on network-wide, zerohash is addressing exactly that gap.

OUSD is supported across Base, Ethereum, Solana and Tempo. The integration underscores zerohash's role as a distribution layer for onchain money, with the company now offering OUSD as a rail for the partners it powers — a roster that today includes industry leaders such as Marqeta and Visa Direct. Multi-chain coverage of this kind lets businesses reach customers and counterparties wherever their payment flows already operate, rather than confining a new token to a single network.

The announcement extends zerohash's position of providing leading institutions and enterprises with access to a broad range of chains, assets and instruments without requiring them to take on the associated regulatory or operational complexity themselves. For partners, zerohash also serves as the interoperability layer between OUSD and other assets and chains.

With OUSD live, zerohash partners can now:

• Leverage zerohash's interoperability layer to move onchain money seamlessly across chains and assets. zerohash provides interoperability between OUSD and more than 15 stablecoins across approximately 25 chains.
• Seamlessly embed support for OUSD across treasury, account funding, payouts and pay-ins use cases.

"We integrated OUSD because it's a stablecoin built for payments by the networks that already move the world's money," said Mark Daly, Chief Business Officer at zerohash. "For our partners, that means they can seamlessly enable OUSD through their existing zerohash integration, without building additional infrastructure, and with full interoperability across the other stablecoins and chains that we support."

OUSD's reach now effectively mirrors zerohash's partner network: any of the company's customers can activate the token through an existing integration, and its real-world footprint will depend on how many of them turn it on across treasury, funding, payouts and pay-ins flows.
