Upbit Denies Role in Open USD Issuance After Dunamu Listed |

Why Is Upbit Distancing Itself From Open USD?

South Korean crypto exchange Upbit said it is not participating in the issuance of Open USD, pushing back after its operator Dunamu was listed among more than 140 businesses involved in the new dollar-backed stablecoin initiative. The exchange said its involvement had been overstated and framed its position as limited to possible future participation in the broader OpenStandard ecosystem. “Upbit has only indicated our potential willingness to consider taking part in the future expansion of the OpenStandard ecosystem,” an Upbit spokesperson said. The clarification places new scrutiny on Open Standard’s launch claims. The project announced Open USD on Tuesday and said more than 140 businesses had “signed up to use” the stablecoin, including Visa, Mastercard, BlackRock, Google, Samsung Electronics and Dunamu. But several South Korean companies named in the announcement have since indicated that their participation was either preliminary, non-binding, or not formally agreed. For digital asset markets, the issue is not only whether one exchange will support a new stablecoin. It is whether Open USD’s early partner list reflects firm commercial commitments or a looser set of expressions of interest. That distinction matters because stablecoin adoption depends heavily on credibility, distribution, redemption access, and institutional trust.

What Are Other South Korean Companies Saying?

Upbit’s statement follows similar pushback from Samsung Electronics and other South Korean businesses listed by Open Standard. Samsung reportedly said it had not held formal discussions with the project and did not know what role it was expected to perform. Shinhan Financial Group and KBank also reportedly said they had only indicated that they would consider the initiative. That language points to a gap between being named as part of an ecosystem and making an operational commitment to issue, support, distribute, or integrate a stablecoin. The distinction is important for banks and large technology companies because stablecoin participation can trigger regulatory, compliance, custody, reserve, payments, and reputational questions. A company may be willing to evaluate a project without agreeing to become part of its launch infrastructure. Open Standard previously said businesses would be able to mint and redeem OUSD without fees or volume limits. The project also plans to distribute earnings generated from its reserves to participating companies. Those features may help attract ecosystem interest, but they also raise questions about the economic model behind the stablecoin and the obligations of listed participants.

Investor Takeaway

The pushback from Upbit and other South Korean firms weakens the market impact of Open USD’s launch announcement. Investors should separate confirmed integrations from non-binding interest, especially in stablecoin projects where distribution claims can shape early credibility.

Why Are The OUSD Economics Being Questioned?

Open USD’s proposed model has drawn questions because it combines free, unlimited minting and redemption with a plan to share reserve-generated earnings with participating companies. That creates a commercial pitch that differs from many stablecoin models, where issuers typically earn income from reserves and may charge or restrict certain services depending on market structure. Circle CEO Jeremy Allaire questioned the sustainability of offering free and unlimited minting and redemption. Lorenzo Valente, director of research at ARK Invest, also described the announcement as a large letter of intent, suggesting that the project’s early partner list may not yet represent operational adoption. The criticism reflects a broader concern in the stablecoin market. A stablecoin can announce a wide business network, but adoption depends on whether users can reliably mint, redeem, hold, transfer, and settle with the token across trusted venues. Without confirmed roles for major companies, the launch risks being treated as an ecosystem proposal rather than a live institutional product. That does not mean Open USD cannot develop into a larger project. It does mean its early market reception may depend on whether Open Standard can clarify which companies are active participants, which are evaluating the product, and which have no formal role.

How Does South Korea’s Unfinished Stablecoin Framework Affect The Issue?

South Korea’s regulatory backdrop makes the situation more sensitive. The country has not yet passed the Digital Asset Basic Act, leaving unresolved questions over who may issue stablecoins and what roles financial institutions, exchanges, and non-bank companies can perform. Lawmakers have debated whether stablecoin issuance should be limited to banks or opened to qualified non-bank issuers. Until those rules are finalized, South Korean firms face uncertainty over issuance rights, reserve management, redemption obligations, and participation in overseas stablecoin ecosystems. That uncertainty helps explain why large companies may be cautious about being publicly listed as participants in a dollar-backed stablecoin project. Even a limited association could be interpreted as a strategic commitment before the legal framework is clear. For exchanges such as Upbit, the regulatory question is especially important. Supporting a stablecoin ecosystem could involve listing, custody, liquidity, user access, compliance monitoring, or technical integration. Each role carries a different regulatory profile, and South Korea has not yet drawn clear lines around those activities. The Open USD dispute shows how stablecoin announcements can move faster than regulatory clarity. For now, Upbit’s response suggests that South Korean companies are not rejecting stablecoins outright, but they are resisting claims that preliminary interest equals direct participation.
