Circle, the issuer of the USDC stablecoin, has signed a memorandum of understanding with South Korea's Kakao Group to explore blockchain-based payment infrastructure, digital asset technologies, tokenized financial services, and the possible development of a Korean won-backed stablecoin.

The agreement brings together Circle's global blockchain infrastructure and international payment network with Kakao Group's broad digital ecosystem, which includes Kakao Corp., Kakao Pay Corp., and KakaoBank Corp. Kakao Group also has existing ties to South Korea's digital asset sector through its affiliation with Dunamu, the operator of Upbit, the country's largest cryptocurrency exchange by trading volume. The companies said the cooperation will examine how blockchain technology could support digital payments, merchant settlement, cross-border remittances, and interoperability between blockchain networks and traditional financial systems in South Korea, one of Asia's largest retail cryptocurrency markets.

Although the companies identified several areas for potential cooperation, they have not announced any specific commercial products, launch schedules, implementation timelines, or issuance plans for a won-denominated stablecoin. The memorandum establishes a framework for evaluation and collaboration, but it is not a binding commercial agreement.

Under the arrangement, Circle and Kakao Group will assess business models that combine Kakao Group's consumer platforms and financial services with Circle's blockchain technology and global payment infrastructure. The discussions will focus on improving payment efficiency, supporting merchant settlements, enabling cross-border transfers, and developing ways for blockchain networks to work with existing financial systems.

Kakao Group plans to draw on the reach of KakaoTalk, one of South Korea's most widely used messaging platforms, as well as Kakao Pay's payments ecosystem and KakaoBank's digital banking services. The companies are also considering shared infrastructure that could allow domestic businesses to develop blockchain-based financial services using common technology standards.

Regulatory Framework Remains Central

The structure of any future Korean won stablecoin, including its issuance mechanisms and operating timeline, has not been determined. The progress of the initiative will depend heavily on South Korea's evolving regulatory framework for digital assets.

Policymakers in South Korea are reviewing legislation, including the proposed Digital Asset Basic Act, along with rules that would determine which entities may issue and manage won-denominated stablecoins. The country implemented the Virtual Asset User Protection Act in July 2024, establishing investor protection and market integrity rules, but the legislation did not address stablecoin issuance frameworks. Regulatory uncertainty has slowed the commercialization of some digital asset initiatives in the country, particularly projects involving fiat-backed stablecoins.

Across Asia, several jurisdictions have moved forward with stablecoin legislation. Japan enacted a stablecoin law in June 2023 allowing licensed entities to issue yen-backed tokens, Hong Kong's Stablecoin Ordinance took effect in 2025, and Singapore has advanced regulated blockchain payment pilots through Project Guardian. South Korea's deliberations over stablecoin-specific rules will shape how quickly initiatives like the Circle-Kakao partnership can progress toward commercial offerings.

Circle Chief Commercial Officer Kash Razzaghi said South Korea has become one of the world's leading digital markets and has a strong foundation for financial innovation. He said Circle aims to pursue opportunities that align with South Korea's regulatory requirements while combining its global blockchain infrastructure with Kakao Group's platform and financial ecosystem.

Kakao Pay Chief Executive Officer Shin Won-keun, who also leads Kakao Group's joint stablecoin task force, said competitiveness in digital assets requires more than technology alone. He said Kakao Group plans to work closely with Circle to prepare for the development of a Korean-style digital asset ecosystem by using its experience in digital platforms, payment services, and financial technology.

Stablecoins and Payment Infrastructure

The agreement reflects growing interest among financial technology companies in integrating stablecoins into mainstream payment infrastructure. Stablecoins are designed to facilitate faster and more efficient transactions while reducing the price volatility commonly associated with cryptocurrencies. USDC ranks as the second-largest stablecoin by market capitalization, behind Tether's USDT.

Circle shared the announcement in an X post on July 23, 2026:

For Circle, the partnership expands its activity in South Korea following earlier collaborations in the country's digital asset sector. The company received a Major Payment Institution license from the Monetary Authority of Singapore in 2023 and has been pursuing regulatory footholds across Asia as part of broader efforts to increase adoption of regulated stablecoin payment solutions across international markets.

South Korea remains one of the world's most active cryptocurrency markets, supported by strong retail participation and growing institutional interest in blockchain-based financial services. The Circle-Kakao collaboration illustrates continued industry efforts to connect stablecoins with mainstream financial services while regulatory discussions over digital assets continue in the country.

As lawmakers develop comprehensive digital asset regulations, the outcome of those rules will help determine when stablecoin-based financial products can move from exploratory discussions to commercial deployment within South Korea's financial system.
