Zero Hash Launches Open USD (OUSD) Support for Global Onchain Payments

Zero Hash has integrated Open USD (OUSD) into its infrastructure, providing its network of fintech and banking partners with immediate access to the stablecoin across multiple blockchains. This move simplifies the deployment of onchain money for institutions like Marqeta and Visa Direct, removing the regulatory and technical hurdles typically associated with multi-chain stablecoin management.

What was announced

Zero Hash has officially launched support for Open USD (OUSD), a stablecoin introduced by Open Standard, making the asset available to its entire partner network. The integration is live across Zero Hash’s full suite of products, providing immediate access for fintech leaders such as Marqeta and Visa Direct. OUSD is currently supported on a diverse range of blockchain environments, including Base, Ethereum, Solana, and Tempo, ensuring that partners can operate across the most active onchain ecosystems.

By acting as a distribution layer, Zero Hash allows its partners to utilize OUSD as a rail for various financial operations. The integration includes an interoperability layer that connects OUSD with more than 15 other stablecoins across approximately 25 different chains. This technical bridge is designed to facilitate the seamless movement of value without requiring partners to manage the underlying infrastructure or regulatory hurdles of each individual chain. Specifically, the capability is aimed at four primary use cases: treasury management, account funding, payouts, and payins. For institutions, this means they can embed OUSD support into their existing workflows through their current Zero Hash integration, avoiding the need for additional engineering resources while gaining the ability to move onchain money with the same fluidity as traditional assets.

The companies involved

Zero Hash is a prominent onchain infrastructure provider that enables businesses to integrate digital assets into their existing platforms. The company operates as a B2B2C entity, handling the underlying regulatory, custody, and liquidity requirements so that its clients can focus on the user experience. Its client base spans traditional fintechs, neo-banks, and payment processors, often serving as the bridge between legacy financial systems and decentralized finance. The firm provides the necessary licensing and technical stack to allow non-crypto native companies to offer digital asset services safely.

Open Standard is the organization behind the OUSD stablecoin. While a newer entrant compared to some of the established stablecoin issuers, Open Standard focuses on creating assets specifically designed for high-velocity payment environments and institutional use. By partnering with infrastructure providers like Zero Hash, Open Standard aims to achieve broad distribution across diverse financial ecosystems. Zero Hash’s role in this partnership is to act as the technical and compliance gateway, ensuring that OUSD can be utilized by regulated entities without those entities having to interface directly with the complexities of various blockchain ledgers or liquidity pools.

What FF News has reported before

Zero Hash has been active in expanding its ecosystem throughout late 2026. FF News recently covered how Underdog Partners with Zero Hash to Enable Stablecoin Funding for Fantasy Sports, demonstrating the provider's reach into prediction markets. The company also recently introduced Zero Hash Launches AUTH to Simplify Onchain Asset Movements and Account Linking, a tool designed to streamline user onboarding. Further institutional expansion was noted when Zero Hash Boosts Institutional Liquidity with Selini Capital Integration. Additionally, the firm collaborated with Ava Labs to produce a report on the Institutional Shift to Onchain Finance, highlighting regulatory clarity as a key driver for adoption.

What this means

The integration of OUSD into a major distribution layer like Zero Hash signals a shift in the stablecoin market toward payment-first assets. While dominant players like USDC and USDT hold the lion's share of liquidity, the entry of OUSD suggests there is still room for assets that prioritize multi-chain interoperability and institutional compliance. This puts pressure on legacy payment rails to prove their efficiency against onchain alternatives that offer near-instant settlement. The industry now faces the question of whether the proliferation of new stablecoins will lead to further fragmentation or if interoperability layers can successfully unify these assets into a cohesive global payment network.
