Several leading South Korean companies have denied formally joining the Open USD (OUSD) Alliance after appearing on the project’s published member list. The unexpected listings have raised questions about how Open Standard defines participation, while the incident comes as South Korea reviews stricter oversight for foreign stablecoin projects.
Several major South Korean technology and financial companies said they never formally agreed to participate in the Open USD Alliance despite being listed publicly. The companies include Samsung Electronics, Dunamu, KakaoBank, Hyundai Card, KB Kookmin Card, Samsung Card, and other financial institutions.

According to local media reports, Open Standard listed 13 Korean companies among more than 140 global participants supporting its planned dollar-backed stablecoin network. However, multiple firms stated they had not completed formal discussions or signed any participation agreements.
Samsung Electronics said no official consultations had taken place regarding the project. The company also stated it remained uncertain about any expected role within the Open USD ecosystem.
Meanwhile, Dunamu, K Bank, and Shinhan Financial Group explained that Open Standard only approached them to gauge possible interest. Their representatives said they merely agreed to review the proposal rather than confirm participation.
One unnamed company representative reportedly said the business only discovered its inclusion through Korean media coverage. The statement added that management expressed surprise after finding its name listed as an alliance member.
The differing accounts have created uncertainty over whether preliminary discussions were mistakenly presented as confirmed participation.
Consequently, questions have emerged regarding the standards used before publishing corporate names on the alliance roster.
Open Standard introduced Open USD on June 30, presenting it as a collaborative stablecoin network backed by more than 140 financial, payment, and technology companies worldwide. The organization stated participating businesses had signed up to use the stablecoin across various commercial applications.
However, several Korean companies disputed that description by emphasizing their conversations never progressed beyond exploratory discussions. Their responses contrast with language suggesting confirmed commitments from every listed organization.
According to Open USD documentation, participating companies would receive technical support while sharing revenue generated from reserve assets supporting the stablecoin. Businesses would also gain access to minting and redemption services without transaction fees or artificial volume restrictions.
The project plans to launch later in 2026 for payments, remittances, settlements, and digital asset trading. Furthermore, Open Standard said reserve assets would remain with regulated United States financial institutions under applicable regulatory requirements.
The broader alliance includes prominent global companies such as Visa, Mastercard, Stripe, Coinbase, BlackRock, BNY, Google, Shopify, IBM, Ripple, Standard Chartered, and DBS. Nevertheless, the Korean membership dispute has shifted attention toward how participation claims are verified before public announcements.
The timing also coincides with South Korea’s ongoing debate over stablecoin regulation. Policymakers continue examining reserve requirements, issuer eligibility, custody standards, and rules governing foreign-issued stablecoins operating within the domestic market.
Industry observers believe greater transparency around partnership classifications could reduce future misunderstandings. Until Open Standard provides additional clarification, uncertainty surrounding several Korean companies’ involvement is likely to remain.
