Dunamu, the Seoul-based company that operates the Upbit exchange, signed a memorandum of understanding with Circle, the US issuer of USD Coin (USDC), during a visit by Circle CEO Jeremy Allaire to the South Korean capital. The signing marked the first in-person meeting between Allaire and Dunamu CEO Oh Kyung-seok, lending additional diplomatic weight to the formalization. The agreement covers education, regulatory compliance, and transparency efforts, with joint programs for market participants listed as the first concrete deliverable. The announcement came as a surprise to some observers: as recently as April 6, a Dunamu official had stated on record that "No specific collaboration details, including an MOU, have been decided. We will discuss various options," according to the Seoul Economic Daily. The signing came five days after South Korea's National Assembly advanced its Digital Asset Basic Act, a comprehensive regulatory framework that includes bank-style reserve requirements for stablecoin issuers. Neither company provided a statement specific to the MOU, and Circle declined to comment when contacted by DL News.

The timing reflects a broader race for positioning in a market that is moving quickly toward formal regulation. Allaire's Seoul schedule extended beyond the Dunamu signing: he also held meetings with KB Financial Group, Shinhan Financial, Hana Financial, Bithumb, and Coinone. According to Maeil Kyungjae, those sessions involved working-level consultations with key executives responsible for actual business implementation, suggesting operational intent rather than ceremonial partnership-building. Tether, USDC's largest competitor, had already visited South Korea ahead of Circle, meeting with KB Financial and Coinone executives. That sequence puts both of the world's two largest stablecoin operators in active pursuit of Korean institutional partnerships at the same moment that lawmakers are writing the rules governing them.

Upbit controls roughly 80% of South Korean crypto trading volume and holds one of only five licenses permitting Korean won-to-crypto trading pairs on a domestic exchange. That concentration makes Dunamu a pivotal distribution partner for any stablecoin issuer seeking local reach. On other Korean platforms, USDC already commands significant volume: the token accounts for approximately 95% of daily trading on Korbit and around 60% on Coinone, suggesting organic demand exists before any formal Upbit integration. As of April 2026, USDC has a circulating supply of approximately 78.6 billion tokens, a market capitalization near $78.8 billion, and has processed more than $197 billion in monthly transactions. In 2026, USDC has captured 64% of adjusted stablecoin transaction volume globally, according to Mizuho research cited by Analytics Insight, outpacing Tether for the first time since 2019. That transaction volume leadership is worth noting alongside the market cap figure: USDC ranks second by market capitalization but first by adjusted transaction share, a divergence that reflects its growing institutional adoption.

The partnership carries regulatory weight beyond its stated education focus. Dunamu's blockchain subsidiary, Lambda256, entered a tripartite memorandum of understanding in March 2026 with law firm Yulchon and analytics company SAS Korea to establish a Stablecoin Council aimed at producing policy recommendations for Korean regulators. The Digital Asset Basic Act, as advanced on April 8, would require stablecoin issuers to hold reserves of at least 100% at licensed banks or approved institutions. A separate dispute between the Bank of Korea and the Financial Services Commission (FSC) remains unresolved: the central bank insists that won-backed stablecoins should only be issued by bank-majority consortia, specifically requiring at least 51% bank ownership, while the FSC has warned that such a restriction could stifle fintech innovation. Circle, which has positioned itself as a compliance-focused issuer, holds a Major Payment Institution license from Singapore's Monetary Authority and operates Circle SBI Japan KK, a joint venture with SBI Holdings in Japan. Those credentials give it standing in that ongoing policy debate. Analysts note that both Dunamu and Circle have clear incentives to influence the stablecoin provisions still being finalized in committee.

Discussions between Circle and Korean financial institutions reportedly include the possibility of a won-backed stablecoin, not only USDC distribution, according to reporting by the Seoul Economic Daily and Korea Herald. Analysts and observers suggest that a Circle-connected Korean won stablecoin could represent a direct response to the central bank's concerns and provide a workable path through the current regulatory impasse. Dunamu itself is navigating institutional headwinds: the company is contesting a roughly 35.2 billion won (about $25 million) fine from South Korea's Financial Intelligence Unit over alleged failures in customer verification and suspicious-activity reporting, and its pending acquisition by Naver Financial at a $10.3 billion valuation has been delayed to an expected close in Q3 2026.

The Korea deal fits a pattern Circle has pursued across Asia. The company expanded its payouts infrastructure to India, Singapore, and the Gulf in early April 2026, following an existing proof-of-concept arrangement with KB Financial Group that dates to June 2025. Across the region, 56% of Asian financial institutions already use stablecoins for settlements, payments, or treasury management, the highest share of any global region, according to Circle data. For retail users in markets where dollar-denominated savings provide a hedge against currency volatility, including Nigeria, Kenya, and parts of Southeast Asia, the regulatory and business model being tested in Korea is relevant as a potential template.

The immediate next marker for this partnership will be how both companies engage with the Digital Asset Basic Act as it moves through committee review in the second quarter of 2026. The educational programs announced in the MOU are a conservative opening move. Whether Dunamu and Circle follow with substantive lobbying on reserve requirements and issuer eligibility will signal how seriously they intend to shape the law rather than simply comply with it.
