Samsung Electronics, Dunamu (which runs Upbit, South Korea's largest crypto exchange), Shinhan Financial Group, and Kbank all say the same thing: they never agreed to join Open Standard's OUSD stablecoin consortium, but their names appeared in the founding partner list anyway.
According to Chosun Biz, a Samsung official stated the company held no formal consultations with Open Standard about the arrangement and has no idea what role it would have played. Dunamu and the others gave similar accounts, saying they had only agreed to review the proposal before being announced as members.
OUSD launched on June 30 to considerable press. The announcement sent Circle's stock lower as investors processed it as a direct threat to USDC. Circle CEO Jeremy Allaire downplayed the threat at the time, arguing the stablecoin market is large enough for multiple competitors.
Where the friction actually lives
The consent problem matters more here than typical corporate name-dropping would. Unlike Tether and Circle, which pocket the yield earned on their reserve assets, Open Standard has promised to distribute most of that income back to partner firms after taking a small operating fee. That structure makes formal membership economically meaningful. Partners get a cut of the money. So does the consent.
Stripe has said OUSD will become the default stablecoin for merchants on its platform. Coinbase confirmed it will list the token on its Base network. Those distribution channels suggested real adoption velocity was possible, which is why the initial backers list mattered to market participants sizing up the stablecoin's staying power.
The denials from household-name Korean firms suggest either Open Standard moved faster than its claimed partners could keep up with, or the partner list was inflated from the start. Neither scenario strengthens confidence in the consortium's governance or the accuracy of its founding announcements. For a stablecoin that trades on its reserve backing and institutional cooperation, credibility about who actually signed on matters more than it would for a token backed only by hype.
The newsroom has not seen a formal response from Open Standard addressing the specific denials, though the company's partner list remains public.
