Chainlink has been selected as an official data oracle for Open Standard’s Open USD (OUSD) stablecoin, which has launched across four blockchains for payments and decentralized finance applications.
OUSD went live on Ethereum, Base, Solana, and Tempo, with more than $1 billion in near-term liquidity commitments from its five founding partners: Coinbase, Mastercard, Shopify, Stripe, and Visa.
Chainlink said its data feeds will provide pricing infrastructure for OUSD-based applications, including lending markets, decentralized exchanges, derivatives and yield products. Oracle feeds can supply blockchain applications with external market data needed for functions such as collateral valuation, liquidations, and settlement.
OUSD targets business payments
Open Standard said OUSD is designed for businesses including financial institutions, fintech companies, merchants, exchanges and DeFi firms. Businesses can convert U.S. dollars into OUSD and redeem the stablecoin at a 1:1 rate without minting or redemption fees. Open Standard says its integration model does not impose artificial volume limits on minting and redemption.
Bridge Building Inc. currently issues OUSD. Open Standard said the stablecoin’s reserves are held with BlackRock, Lead Bank, and BNY, with monthly reserve attestations expected through Bridge.
Businesses that join Open Standard as network partners can also earn rewards based on qualifying OUSD balances and activity.
Stripe and Mastercard expand OUSD access
Stripe said OUSD is now supported across several of its products, including Treasury, Issuing, Global Payouts, Crypto Onramp, and Payments.
Businesses can use OUSD to receive, hold, send and spend funds, build card programs, make global payouts and offer fiat-to-OUSD conversions. Stripe said OUSD is its default stablecoin configuration on the Tempo blockchain, while customers can continue to choose other supported stablecoins and networks.
Mastercard said OUSD will be available through BVNK, the stablecoin infrastructure company it acquired earlier this year.
Financial institutions, distributors and enterprises will be able to access OUSD through BVNK alongside fiat currencies and other stablecoins. Mastercard said the integration can help businesses manage liquidity, supplier payments and cross-border transactions through existing infrastructure.
Visa also supports OUSD through its Stablecoin Platform, while Coinbase provides access for conversion, custody, trading, financing and payment services.
Chainlink expands OUSD’s DeFi use
The Chainlink integration is intended to provide data infrastructure for OUSD-based onchain financial applications.
Chainlink Data Feeds can provide reference prices for lending and borrowing markets and support pricing, margin and settlement functions for applications that integrate the feeds. The availability of those uses will depend on individual protocols integrating the feeds and establishing their own risk parameters.
Aave Labs has also proposed adding OUSD to Aave V3 on Ethereum and the Aave V4 Core Hub. Under the proposal, OUSD would initially be available for supply and borrowing, while its use as collateral would remain disabled until the asset establishes sufficient onchain liquidity and price history.
Aave’s proposal says the oracle parameters and other risk settings will be populated once Chainlink price feeds are live in production. The proposal remains subject to Aave’s governance process.
More than $1 billion in launch liquidity
Open Standard said its five founding partners are helping establish more than $1 billion in near-term liquidity commitments for OUSD.
The project said its wider network includes more than 200 financial institutions, fintech companies, banks and other businesses.
Open Standard’s model allows participating partners to receive rewards linked to OUSD supply and activity generated through their platforms.The project has positioned OUSD for payments and financial applications alongside DeFi use cases.
Bridge bank approval remains conditional
Bridge’s OUSD launch follows the Office of the Comptroller of the Currency’s preliminary conditional approval of Bridge National Trust Bank in February 2026. The proposed bank would cover activities including stablecoin issuance, digital-asset custody, payment orchestration and reserve management.
The OCC said the approval was preliminary and conditional and that final approval authorizing the bank to commence business would require the completion of preopening requirements. Bridge National Trust Bank is therefore not yet operational under the charter.
Bridge Building Inc. continues to issue OUSD.
With OUSD now live across four blockchains, Open Standard and its partners are focused on expanding its use across payments, financial services and DeFi.
