Open USD (OUSD), a dollar stablecoin issued by Stripe-owned Bridge and governed by a consortium called Open Standard, went live on 30 September. On the same day Stripe made it the default stablecoin configuration across its products. The founding partners are Coinbase, Mastercard, Shopify, Stripe and Visa, and Unchained reports they put more than $1 billion into seeding its supply at launch.
If you already accept stablecoins through Stripe, or pay contractors and affiliates abroad, the default you are building on has just changed.
What OUSD is
OUSD is a 1:1 US dollar-pegged stablecoin. Per Unchained, its reserves are held at BlackRock, Lead Bank and BNY, with monthly attestations, and minting and redemption at par are free through partner platforms. It runs on four blockchains: Base, Ethereum, Solana and Tempo, the last being the payments chain Stripe backs.
The unusual part is the economics. Most stablecoin issuers keep the interest earned on reserves. Open Standard shares it: according to Stripe, businesses that join as partners can earn rewards based on their OUSD activity, including OUSD balances held on Stripe. Unchained adds that partners can also earn equity in Open Standard.
Reports disagree on the size of the consortium. Stripe's post says more than 200 partners support the network, and Unchained says the same, noting there were 140 or more when it was unveiled in June. Bloomberg's headline figure is more than 100 corporations. The higher, more recent figure comes from Stripe itself.
What "default on Stripe" means
Stripe says OUSD on Tempo is now its default stablecoin configuration, but you can still choose another stablecoin and chain. It is supported in:
Payments: accept OUSD directly. Treasury: receive, hold and send funds. Global Payouts: send money to recipients worldwide. Issuing: build card programmes funded by stablecoin balances. Crypto Onramp: let customers convert fiat to OUSD.
Stripe says it will not require anyone to convert existing stablecoin balances. It describes transaction fees as low and predictable, with no minting or burning fees, but the post does not publish a rate.
Outside Stripe, businesses can reach OUSD through the Mastercard, Stripe and Visa Stablecoin Platform now and through Coinbase from 1 October. Unchained lists Coinbase, Kraken and Uniswap as the first trading venues.
Why a SaaS founder should care
For most SaaS companies, stablecoins matter at the edges rather than the core. Card and bank payments still dominate. Where stablecoins earn their place is cross-border money movement: customers in countries where cards fail or cost a lot, and payouts to contractors, affiliates or marketplace sellers abroad, where wire fees and FX spreads bite.
OUSD's pitch is that Visa, Mastercard, Coinbase and Stripe all back the same coin, so it should be accepted widely without conversion. For anyone paying out internationally, that could reduce the number of hops between your balance and the recipient. The reward on balances also makes holding a working float in OUSD less costly than holding a stablecoin that pays nothing.
The caveats: OUSD is one day old, liquidity on each chain is still building, and rewards depend on joining the partner programme on terms we have not seen published in full. Stablecoin rules also differ by country, and accepting or holding them can have accounting and tax consequences.
What to actually do
1. Check your Stripe stablecoin settings. If you accept stablecoin payments, confirm which coin and chain new payments settle in now that the default has changed, and update any reconciliation or accounting that assumes a particular token.
2. Look at your payout costs. If you pay people abroad, add up last quarter's wire fees and FX spread. That is the number a stablecoin payout route has to beat.
3. Read the partner terms before chasing rewards. Rewards on balances are only worth it if the terms, reporting and exit options suit you. Ask Stripe for the rate and conditions in writing.
4. Talk to your accountant first. Before holding a treasury balance in any stablecoin, confirm how it is treated in your jurisdiction for accounting, tax and any licensing rules.
The bottom line
OUSD is the first dollar stablecoin backed at once by both card networks, Coinbase, Shopify and Stripe, and Stripe has made it the default from day one. For a SaaS team it is most useful for international payouts and customers outside the card system. Check what your Stripe stablecoin settings now default to, compare payout costs, and wait for published reward terms before moving treasury balances.
