OUSD can be minted and redeemed at a 1:1 ratio with the US dollar at no additional cost through supported integration paths, while its reserves are held by BlackRock, Lead Bank and BNY.

For users asking how to access Open USD, the main route is currently through supported business and developer integrations rather than simply treating OUSD as another retail-focused crypto asset. 

Its native deployment across four blockchains is designed to make the same stablecoin available across multiple payment and financial infrastructure environments.

Key Takeaways

• Open USD launched on September 30, 2026, with OUSD natively available on Solana, Base, Ethereum and Tempo.
• More than $1 billion in launch liquidity has been committed by Open Standard's five founding partners, while the wider network has grown to more than 200 participating businesses.
• Businesses can access OUSD through supported integration providers, with 1:1 minting and redemption available without additional fees for eligible users.

What Is Open USD (OUSD)?

Open USD, or OUSD, is a US dollar-pegged stablecoin created by Open Standard for business and financial applications.

Unlike a token designed primarily around speculative trading, OUSD is positioned as infrastructure for moving dollars through internet-native financial systems. 

Its stated use cases include banking, cross-border payments, settlement, treasury management, foreign exchange, cards and institutional financial services.

OUSD is issued by Bridge, while its reserves are held by BlackRock, Lead Bank and BNY. Bridge plans to publish reserve attestations on a monthly basis.

The stablecoin is designed to maintain a 1:1 relationship with the US dollar. Eligible businesses can mint and burn OUSD at the same 1:1 rate without additional minting or redemption fees through supported access routes.

When Did OUSD Launch?

OUSD launched officially on September 30, 2026.

The launch followed the introduction of Open Standard earlier in 2026, when the project announced a network of more than 140 participating companies. By the September launch, the network had expanded to more than 200 partners across financial services, payments, technology and commerce.

The September 30 launch also moved OUSD from an announced stablecoin initiative into live infrastructure that businesses and developers can begin using.

OUSD launched natively across four blockchain networks:

• Solana
• Base
• Ethereum
• Tempo

Native deployment means OUSD exists directly on each supported network rather than relying on a wrapped version of the token.

Where Is OUSD Available?

OUSD is currently supported natively on Solana, Base, Ethereum and Tempo.

This multi-chain structure is central to Open Standard's approach. Businesses can select an integration path and use OUSD across supported financial applications without requiring the stablecoin to depend on a single blockchain.

OUSD on Solana

OUSD launched natively on Solana on September 30.

The Solana deployment is designed for payment, settlement and treasury use cases, with businesses able to mint and burn OUSD at a 1:1 ratio.

The native Solana token uses the Token-2022 standard. This allows OUSD to operate directly within Solana's infrastructure rather than as a representation of an asset issued elsewhere.

OUSD on Base

OUSD is also live natively on Base.

Base provides another environment for developers and businesses building financial applications around OUSD. Its inclusion gives Open Standard another Ethereum-compatible network for payments, settlement and related applications.

OUSD on Ethereum

OUSD launched natively on Ethereum as part of the September 30 rollout.

Ethereum's inclusion gives businesses and developers access to OUSD within one of the largest smart-contract ecosystems. The token's multi-chain design means Ethereum is one part of a broader deployment rather than its sole home.

OUSD on Tempo

Tempo is the fourth network supporting OUSD at launch.

Its inclusion further extends OUSD's reach into payment-focused blockchain infrastructure. Together, the four networks provide multiple environments for businesses building around the stablecoin.

How Can Businesses Access Open USD?

Access to OUSD is structured around business and developer integrations.

Open Standard currently provides four major integration paths through its participating infrastructure partners. 

These routes provide tools for functions such as payments, settlement, wallets, foreign exchange, card programmes, on- and off-ramps and other financial services.

The available integration routes support OUSD minting and burning at a 1:1 USD conversion rate.

Businesses generally need to complete the relevant onboarding and account requirements with their selected provider before accessing OUSD.

This means the practical answer to how to access Open USD depends on what the business is trying to build. 

A company handling payments may need a different integration from a developer building a wallet, settlement system or financial application.

How Does OUSD Minting and Redemption Work?

OUSD is designed around a straightforward 1:1 conversion model.

Eligible businesses can:

1. Provide US dollars through a supported integration.
2. Mint the corresponding amount of OUSD.
3. Use OUSD for supported payment, settlement or financial applications.
4. Burn OUSD to redeem the corresponding US dollar value.

The project states that minting and burning are available without additional fees through its supported integration routes.

This model is intended to reduce friction for companies that want to use stablecoins without treating the token as a separate speculative asset.

Access remains subject to onboarding requirements, geographic restrictions and the terms applicable to each service provider.

Why Did OUSD Launch With More Than $1 Billion in Liquidity?

Liquidity is one of the major headlines surrounding the OUSD launch.

Open Standard's five founding partners have committed more than $1 billion to establish initial OUSD liquidity. The founding group includes Visa, Mastercard, Shopify, Stripe and Coinbase.

The scale of the commitment is significant because stablecoins depend heavily on distribution, liquidity and real-world usage. 

A token can maintain a dollar peg technically, but its usefulness also depends on whether businesses can actually access and transact with it efficiently.

Open Standard has therefore structured OUSD around a broader network of participating businesses rather than relying solely on the stablecoin's initial launch.

The project says more than 200 companies are now part of the wider network.

What Makes the OUSD Model Different?

OUSD's model focuses heavily on business participation and shared economics.

Open Standard says participating partners can receive rewards based on the supply and activity they help generate across the OUSD network. The model is designed to encourage businesses to integrate the stablecoin into their existing financial products and payment flows.

That creates a different incentive structure from a stablecoin model in which reserve income is concentrated primarily with a single issuer.

The broader objective is to make OUSD useful as financial infrastructure rather than simply another dollar-denominated token.

However, the launch is still an early stage for the network. Actual adoption will depend on how quickly businesses integrate OUSD, how much transaction activity develops across its supported chains and whether the network can maintain useful liquidity over time.

What Should Users Watch After the OUSD Launch?

The first major indicator will be actual OUSD usage.

The initial $1 billion-plus liquidity commitment provides an important starting point, but liquidity commitments alone do not establish long-term adoption.

Several developments are worth monitoring:

Business Integration

The number of businesses integrating OUSD will help show whether the stablecoin is gaining practical utility beyond its launch partners.

Transaction Activity

Payment, settlement and treasury activity can provide a clearer indication of real-world usage than launch-day liquidity figures alone.

Multi-Chain Liquidity

OUSD is live across four networks, so how liquidity develops across Solana, Base, Ethereum and Tempo will be another important factor.

Reserve Transparency

Bridge's planned monthly reserve attestations will provide information about the assets backing OUSD and should remain an important part of monitoring the stablecoin.

Access Expansion

The availability of additional integration routes and financial applications could determine how easily businesses can incorporate OUSD into existing systems.

Can Retail Users Access OUSD?

OUSD's initial positioning is primarily focused on businesses and developers, rather than being presented as a conventional retail stablecoin product.

Open Standard provides access through integration infrastructure designed for payments, settlement, wallets, trading, foreign exchange and other financial applications.

Individual availability can therefore depend on the specific service, jurisdiction and eligibility requirements involved.

For anyone considering OUSD, it is useful to distinguish between the token being technically live on a blockchain and having direct access through a particular financial service. Those are not necessarily the same thing.

What the OUSD Launch Means for Stablecoin Access

The September 30 launch establishes Open USD as a live stablecoin infrastructure project spanning four blockchain networks and more than 200 participating businesses.

Its initial rollout combines native multi-chain deployment, fee-free 1:1 minting and redemption for eligible businesses, and more than $1 billion in liquidity commitments from its founding partners.

For businesses, the main attraction is not simply access to another dollar-pegged token. OUSD is designed to connect stablecoin functionality with payments, settlement, treasury management and other financial infrastructure.

The next stage will be measured by actual adoption. Business integrations, transaction activity, liquidity across the four supported networks and ongoing reserve transparency will provide a clearer picture of how Open USD develops after its initial launch.
