Open Standard launches OUSD live across Ethereum, Solana, Base, and Tempo

Open USD (OUSD) is live. Open Standard said Wednesday that its dollar stablecoin launched natively across Ethereum, Solana, Base, and Stripe-aligned Tempo, with founding partners Coinbase, Mastercard, Shopify, Stripe, and Visa each taking an equal initial equity stake and committing more than $1 billion toward near-term liquidity. That is today’s unused Stablecoin Settlement beat: a payments-rail stack going live—not another Bitget reopen chapter (10355) and not a Lion Group HYPE treasury rehash (10398). Primary desk reads from CoinDesk, CryptoBriefing, and on-chain supply wraps on Lookonchain.

What clears on day one. Open Standard positions OUSD for banking, cross-border payments, settlement, institutional trading, and lending. Businesses can mint and redeem at a 1:1 dollar rate with no mint or burn fees through Stripe, Mastercard’s BVNK, and the Visa Stablecoin Platform; Coinbase integration is scheduled to begin October 1. The token is issued by Bridge, the Stripe-owned stablecoin infrastructure firm, with reserves held at BlackRock, Lead Bank, and BNY, and monthly reserve attestations planned. Day-one trading venues named in the launch wraps include Coinbase, Kraken, and Uniswap—treat those as company-stated venue lists, not as proof every jurisdiction can trade.

Early supply that the settlement desk can bold. Lookonchain’s Sep. 30 wrap says OUSD’s on-chain supply reached about 477.3 million tokens roughly two hours after launch, with reserve assets matched at about $477.3 million (100% coverage in that snapshot). The same feed breaks reserves at roughly $211.2 million U.S. Treasuries (~44.25%) and $266.1 million USD cash (~55.75%), and puts Tempo circulating supply near 434.2 million with cumulative Tempo transfer volume about $533.9 million—more than 90% of early supply sitting on Tempo. Do not invent that those figures are audited year-end statements; they are launch-day monitoring numbers attributed to the wraps.

Why NFT and crypto desks still care. Collectors already clear bids and royalties through dollar rails; a new stablecoin with fee-free mint/redeem paths and named payment giants changes which settlement asset venues can route. Open Standard’s pitch—CEO Zach Abrams telling CoinDesk the firm is “building money,” not “building a fund”—is the distribution story: partners earn rewards from the OUSD supply and activity they drive, and the company says an “overwhelming majority” of its equity will eventually go to founders and partners based on how they grow the network over roughly four to five years. Founding partners do not get a separate preferred slice of reserve yield under that framing; they sit in the same usage-based reward framework once they clear partner thresholds Open Standard has not fully published.

Market context without cheerleading. OUSD enters a stablecoin market CoinDesk puts above $300 billion, still dominated by Tether’s USDT (~$143 billion) and Circle’s USDC (~$74 billion). The June unveil rattled Circle when Coinbase, Visa, and Mastercard showed up in the partner list; today’s chapter is go-live, not the teaser. Partner network size is now cited above 200 companies, with UBS, Japan’s SBI Holdings, and fintech Jeeves among newer names. Tempo’s Dan Romero told CoinDesk he sees a path toward roughly $1 billion of OUSD on Tempo in coming months—company aspiration, not a cleared mint schedule.

What this tick is not. It is not Drift’s $9.2 million freeze (10394), Binance’s seven bStocks pairs (10396), or Coinbase’s Pokémon vault tease (10392). Daily Crypto Brief draft 10376 stays untouched. Desk of the Day is already spent for Sep 30 on Bitget’s USDT reopen—no DotD line here. Do not invent that OUSD has displaced USDT/USDC liquidity or that every partner is already holding the full $1 billion commitment on-chain today.

Settlement watch: next clocks are Coinbase’s October 1 integration window, the first monthly reserve attestation print, and whether Tempo’s early ~434 million OUSD stack keeps growing toward Romero’s near-term $1 billion talk—or bleeds onto Ethereum, Solana, and Base as venue depth catches up.

Bottom line: Open Standard’s OUSD went live Wednesday on Ethereum, Solana, Base, and Tempo with fee-free 1:1 mint/redeem paths and more than $1 billion in named partner liquidity commitments—early on-chain supply already near 477 million, mostly on Tempo.
