Open Standard has launched Open USD (OUSD), a new U.S. dollar-backed stablecoin supported by more than $1 billion in committed short-term reserves, with Chainlink serving as its official oracle partner. The company said the asset is designed to expand access to dollar-based digital payments and financial services. Stablecoins are blockchain tokens designed to hold a fixed value against a reference asset — in this case, the U.S. dollar.

The stablecoin is initially available across Base, Ethereum, Solana, and Tempo, with additional blockchain networks and financial integrations planned. According to Open Standard, the launch is intended to give businesses infrastructure for moving funds between traditional currencies and blockchain networks.

Open USD can be converted between U.S. dollars and OUSD at a 1:1 rate, and businesses can mint and redeem the stablecoin without fees through integrations and application programming interfaces (APIs) — minting creates new tokens when dollars are deposited, while redemption converts tokens back into dollars. The launch brings together a network of payment processors, banks, trading venues, and oracle providers, positioning the stablecoin across both conventional finance on-chain markets.

Payment and Financial Infrastructure

Open Standard said businesses can access OUSD through integrations involving Stripe, Mastercard, Visa, and Coinbase. BVNK, Stripe, and the Visa Stablecoin Platform are among the services available at launch, while Coinbase support was scheduled to become available on Oct. 1.

Other early trading venues include Coinbase, Kraken, and Uniswap, giving OUSD access to established cryptocurrency markets as the stablecoin begins building liquidity.

Bridge Building Inc., a Stripe subsidiary, is responsible for minting OUSD. Open Standard said BlackRock, Lead Bank, and BNY are maintaining the reserves backing the stablecoin. Bridge is expected to provide monthly attestations covering those reserves — periodic reports confirming the holdings behind the token — adding a regular reporting mechanism for users and market participants.

Stripe and Bridge provide payment and financial infrastructure that includes wallet services, payment capabilities, and mechanisms for moving between fiat currencies and digital assets. Mastercard has also partnered with BVNK, while Visa is making OUSD available through its Stablecoin Platform, which remains in beta and is accessible to selected users in certain locations.

Chainlink Provides Oracle Infrastructure

Chainlink has been designated as an official oracle partner for Open USD. Oracle networks provide blockchain applications with external information — such as market and financial data — that can be used by smart contracts.

The integration could allow OUSD to be incorporated into a broader range of decentralized financial products, with potential applications including lending, margin trading, automated market makers, and yield-generating services.

The Chainlink integration is intended to give OUSD access to reliable external data, allowing developers to connect the stablecoin with financial applications that require market information and automated smart-contract operations.

Aave Labs has already outlined a potential use case involving OUSD within decentralized finance. Its proposal includes support for OUSD on Aave V3 Ethereum and the Aave V4 Core Hub, where users could deposit and borrow the stablecoin but would initially be unable to use it as collateral.

According to the proposal, higher loan-to-value limits and other collateral-related improvements could be considered after additional on-chain data becomes available. The oracle configuration has not yet been finalized, while other risk parameters are expected to be determined through community input and the availability of Chainlink feeds for the production network.

Chainlink announced the designation on X on September 30, 2026:

Major Companies Back Open Standard

Open Standard was founded by Coinbase, Mastercard, Shopify, Stripe, and Visa. The five companies are investors in the organization and are providing support for efforts to establish more than $1 billion in initial trading capital for OUSD.

Mastercard confirmed its involvement on X the same day:

Businesses have more ways to move value than ever before. The challenge isn't creating more forms of money. It's helping businesses use them. Mastercard will make Open USD (OUSD) available through @BVNK, helping customers access new forms of value movement through… pic.twitter.com/IqReszBR9s

Open Standard said its broader partner network includes more than 200 financial institutions, fintech companies, banks, and multinational corporations. Securitize has also joined the OUSD network and plans to offer OUSD-related services through its tokenization platform, which represents assets as digital tokens on blockchains.

The project has established a partner incentive structure based on OUSD supply and activity generated through participating platforms. That approach could encourage financial and technology companies to expand their use of the stablecoin.

In a related development, Bridge has received preliminary conditional approval from the U.S. Office of the Comptroller of the Currency, the federal regulator that charters and supervises national banks, to establish Bridge National Trust Bank in New York. The proposed bank has not yet been established, and the preliminary approval remains subject to additional pre-opening requirements.

With the launch complete, the items still in motion include the first monthly reserve attestation, Coinbase's scheduled Oct. 1 integration, the Aave governance process around OUSD support, and the pre-opening requirements attached to Bridge's preliminary bank approval.

The launch places Open USD at the intersection of stablecoin payments, institutional financial infrastructure, and decentralized finance. Its long-term adoption is likely to depend on liquidity, reserve transparency, regulatory progress, and the number of businesses and developers integrating the asset.
