Open USD (OUSD) and USDC are both live, fully reserved dollar stablecoins, but OUSD is far smaller and is governed by a partner consortium rather than a single company. OUSD went live on September 30, 2026, per Open Standard, and DefiLlama shows about $0.70B of OUSD circulating against roughly $74.3B of USDC as of October 6, 2026.
The two coins differ less on backing than on who issues them, who earns the reserve income, and how far they reach. OUSD is issued by Bridge, a Stripe company, on behalf of Open Standard, per Open Standard's launch post. USDC is issued through regulated affiliates of Circle, per Circle. The sections below compare them on live, published facts.
How do Open USD and USDC differ at a glance?
Open USD and USDC are both dollar stablecoins backed by cash and short-dated Treasuries. They differ on issuer, governance, and who keeps the reserve income. USDC is run by one company that retains most of that income. OUSD is run by a partner-owned company that passes most of it to the platforms that distribute the coin.

Who issues Open USD and USDC?
USDC is issued by Circle, which sets policy for the coin on its own. Open USD is issued by Bridge, a Stripe company, and governed by Open Standard, a separate company owned by its partners. The split between issuer and governing company is the main structural difference between the two coins.
Per Open Standard's September 24 structure update, Coinbase, Mastercard, Shopify, Stripe and Visa are the initial founding partners, each investing in the company and helping deliver $1B+ in near-term launch liquidity. Zach Abrams, who founded Bridge, became full-time CEO of Open Standard in the same update.
The broader partner network is larger. Open Standard says over 200 financial institutions, fintechs, banks and businesses have signed up to add OUSD, and its partner list names card networks, banks such as BNY and Standard Chartered, and crypto firms such as Solana and Polygon. Signing up is a commitment to integrate, not proof of live volume.
What backs each stablecoin?
Both coins hold cash and short-dated US Treasury exposure, and both publish reserve reports. USDC's reserves sit mostly in a BlackRock-managed government money market fund. OUSD's reserves are split between cash and Treasury money-market funds held at large US institutions, with a live reserve dashboard run by its issuer.
Bridge's OUSD reserve page showed 709,002,987 OUSD in circulation and $709,003,102 in reserves on October 6, 2026, split 13.3% cash and 86.7% Treasuries, where Treasuries include money-market funds of T-bill ladders under three months. Open Standard says reserves are held at BlackRock, Lead Bank and BNY, with monthly attestations.
Per Circle, the majority of USDC reserves are in the Circle Reserve Fund (USDXX), an SEC-registered 2a-7 government money market fund managed by BlackRock and custodied at BNY, and Circle publishes monthly attestations by a Big Four firm. The practical gap is track record: USDC has years of attestations, OUSD has days of live data.
How does governance work in each model?
USDC governance is corporate. Circle decides on new chains, reserve policy and partner terms by itself. OUSD governance runs through Open Standard, whose board is to be drawn from founding partners and represent shareholders. Partners that drive the most OUSD adoption are meant to gain the most say over time.
Per Open Standard, the board of directors will be established over time, and participating partners can earn equity based on the supply and activity they drive. Single-issuer governance moves faster. Consortium governance asks competitors such as Visa and Mastercard to share one asset, which only works if no single member controls it.
How do partner economics compare?
Partner economics is where the two models differ most. OUSD is designed to pass nearly all reserve income to the platforms that grow its supply and usage, and to let those platforms earn equity. USDC income goes to Circle, with revenue shares agreed separately with individual distribution partners.
Open Standard describes nearly all reserve revenues as shared with companies that grow adoption, and no fees to mint or redeem. Its launch post says all four integration paths support 1:1 mint and burn at no cost. Exact reward rates per partner are not published, so the payout a given platform receives cannot be checked from public sources.
Where can you get Open USD and USDC?
USDC is already available across most major exchanges, wallets and payment providers. OUSD started with four integration paths, through Coinbase, Mastercard, Stripe and Visa, and named exchange venues at launch. Its distribution is new and narrower, while USDC's reach reflects years of integrations across a large number of chains.
Per Open Standard's launch post, businesses could build with BVNK, Stripe and the Visa Stablecoin Platform at launch and with Coinbase starting October 1, and OUSD is to be available on Coinbase, Kraken and Uniswap first. The integration page lists Stripe, Bridge and Privy, Mastercard, Coinbase and Visa as access routes.
Coinbase sits on both sides. It is a long-standing USDC distributor and a founding partner of Open Standard, per Open Standard. That overlap suggests venues will list OUSD alongside USDC rather than in place of it.
How are they regulated?
USDC is issued through regulated Circle affiliates and has a long public compliance record. OUSD is issued from the US by Bridge, and Open Standard says reserves are kept at major financial institutions in line with US requirements. Treasurers should review each issuer's current licenses directly before holding either coin at size.
Open Standard says OUSD reserves are maintained at major financial institutions in compliance with US regulatory requirements, and Bridge lists the coin as issued from the US. Access is subject to Open Standard's geo restrictions and prohibited use cases. Circle says USDC is issued through its regulated affiliates and that it obtains the licenses it needs.
What about cross-chain availability?
USDC runs natively on dozens of networks and has its own burn-and-mint transfer protocol between them. OUSD is native on four chains: Base, Ethereum, Solana and Tempo. For apps that need dollars on many chains, USDC covers far more ground today, while OUSD covers the largest payment-focused networks.
Official OUSD contracts are on Base, Ethereum, Solana and Tempo. USDC is native on 38 networks as of September 16, 2026, per Circle, and moves between them with Circle CCTP. Open Standard has not published a cross-chain transfer protocol for OUSD.
Where this falls short
This comparison has limits. OUSD has been live for about a week, so its supply, liquidity and reserve history are thin. Partner reward rates are not public. Supply figures for both coins move daily, so the numbers here are a snapshot on one date and should be rechecked before any decision.
First, OUSD's live record is short: OUSD went live on September 30, 2026, per Open Standard, and monthly attestations have only just begun. Second, partner economics are described in principle on Open Standard's site, not as a published payout schedule.
Third, neither coin pays yield to ordinary holders. OUSD routes reserve income to partners, and USDC routes it to Circle and its negotiated partners. Treasurers who want yield on their own balance sheet are looking at a different category of tokenized fund products.
Will Open USD replace USDC?
Replacement is unlikely in the near term. USDC is roughly a hundred times larger than OUSD by circulating supply and runs on far more chains. OUSD's advantage is economic: platforms that distribute it keep most of the reserve income. The likelier outcome is that payment platforms hold and route both.
On DefiLlama data for October 6, 2026, USDC supply of about $74.3B compares with about $0.70B of OUSD. For a business integrating stablecoins, the more useful takeaway is that issuer choice keeps widening, so infrastructure that can route across several dollar stablecoins carries less single-issuer risk than a build tied to one.
Routing across multiple stablecoin issuers
As more dollar stablecoins go live, payment teams face more assets, more chains and more liquidity pools. Routing infrastructure lets a business accept or send whichever stablecoin offers the best execution for a given payment, without building a separate integration for each new issuer it wants to support.
Eco Routes moves stablecoins across chains and issuers based on liquidity, fees and destination, and can evaluate OUSD against the same criteria as USDC and other dollar stablecoins.
