Open Standard Launches OUSD Across Four Chains, but Liquidity Is Unclear

Open Standard launched OUSD on Ethereum, Solana, Base and Tempo on 30 September 2026, giving the dollar stablecoin a four-chain start. The practical question for holders is whether those networks offer enough liquidity, reliable redemption and useful distribution to support real payments.

The evidence so far is strongest on distribution. It is weakest on chain-by-chain liquidity.

Stripe Opens OUSD to Businesses

Stripe launched OUSD support across Treasury, Issuing, Global Payouts, Crypto Onramp and Payments on the same day. Businesses can use the token to receive, hold, send and spend funds through Treasury, operate global card programmes and pay recipients overseas.

Stripe also says OUSD has no minting or burning fees. Businesses may receive rewards based on activity, including balances held through Stripe. Finance platform Ramp plans to use Stripe for stablecoin accounts that hold OUSD, while Bridge orchestration APIs can convert OUSD into fiat or other stablecoins.

That gives Open Standard a distribution route through Stripe's products. It does not show how many OUSD balances Stripe currently holds or whether customers can readily buy and sell the token.

Each Network Has a Different Role

OUSD is now Stripe's default stablecoin configuration on Tempo. Stripe says customers can still choose another stablecoin and blockchain, and existing balances will not be forced into OUSD. Tempo therefore has the clearest launch role inside Stripe's product stack.

Solana offers OUSD a high-speed network outside Stripe's default configuration. Its early supply was 18.01 million tokens across 47 wallets as of 19:24 UTC on 30 September, according to Solana Compass. USDC on Solana had 7.86 billion tokens across 9.31 million wallets two minutes later, underlining how small OUSD's launch footprint was.

OUSD is also live on Ethereum and Base, but the research found no network-specific supply, holder or liquidity figures for either chain. Open Standard has not said how total supply will divide among its four networks. Without that split, it is not possible to compare the depth of OUSD markets on Ethereum, Base, Solana and Tempo.

Reserves Are Named, but the Mix Is Unclear

Bridge, a Stripe company, issues OUSD, while Open Standard runs the stablecoin. Launch information identifies BlackRock, Lead Bank and BNY as reserve holders. Bridge publishes monthly reserve attestations, which allow users to examine the reported reserve position rather than rely only on Open Standard's claims.

The available information does not set out the allocation between those reserve holders or show how much reserves are attributable to each chain. That matters. A common issuer and reserve structure can support trust across networks, but it does not create equal liquidity on every network.

For now, all four chains carry the same OUSD ticker and issuer relationship. Their practical liquidity may still differ sharply.

Distribution Is Clearer Than Liquidity

OUSD's access points include Stripe and a wider group of on-ramps and trading venues. Open Standard has also assembled a partner network that includes major financial and technology companies. The backing announcements therefore focus less on crypto-native liquidity pools and more on payments companies, banks and business infrastructure.

That may help distribution, but it leaves several questions for holders:

• How much OUSD was issued on each chain at launch?
• How deep are the secondary-market pools and trading pairs?
• How quickly can users redeem through banks or payment partners?
• Do monthly attestations disclose any chain-specific reserve allocation?

Until those figures are published, OUSD is best viewed as a new stablecoin with confirmed business integrations, not yet a proven four-chain liquidity market.

Holders should also check the token address before trading on Solana: ousd2mJsPEckLHcSCDxyKD7NDGARZcfLbDZkKiatYHB. Origin Dollar also uses the OUSD ticker, but it is a separate project.

The ticker collision is an avoidable operational risk. Comparing liquidity across the four chains is harder because Open Standard has not yet supplied the basic chain-level numbers needed to make that comparison.
