Circle has signed separate memorandums of understanding (MOUs) with Kakao Group and Toss to expand blockchain-based payment infrastructure and accelerate USDC adoption in South Korea. The agreements, announced on July 23, focus on exploring stablecoin-powered financial services, digital asset connectivity, and cross-border payment solutions through two of the country's largest fintech ecosystems. The push comes as USDC, the second-largest stablecoin by market capitalization, faces intensifying global competition from rivals seeking share in Asia's digital payments market.

Kakao Partnership Targets Payments and Digital Asset Connectivity

The Kakao partnership covers Kakao Group, Kakao Pay, and KakaoBank. Together, the companies will assess opportunities for USDC across payments, settlements, and digital asset connectivity. Kakao Pay serves more than 40 million registered users, providing Circle with significant exposure if future USDC-based services receive regulatory approval.

Circle stated that both companies will evaluate how its global payment rails can support digital finance applications. However, neither company disclosed specific products or implementation timelines. Any rollout would depend on how South Korea's digital asset regulatory framework evolves, as lawmakers continue to debate legislation governing stablecoins and tokenized securities.

Toss Collaboration Explores Programmable Payments and Remittances

The separate agreement with Toss and Toss Bank expands Circle's presence across another major Korean fintech platform. The collaboration will examine blockchain payment infrastructure and stablecoin technology for consumer and banking services.

The companies plan to explore programmable payments using blockchain technology and will also assess biometric authentication for USDC transactions and stablecoin-powered overseas remittances. Additionally, Toss Bank will evaluate connections between Circle's infrastructure and traditional bank settlement systems, with the goal of improving the speed and efficiency of international payments. For a country that ranks among the world's top trading economies, faster and cheaper cross-border settlement remains a persistent friction point that blockchain-based rails aim to address.

South Korea as a Strategic Market

Circle's latest agreements strengthen its long-term strategy in South Korea. The company has steadily expanded partnerships with major financial institutions across the country. In 2025, Circle signed a separate agreement with Hana Bank to promote USDC adoption for cross-border remittances and treasury services. The latest partnerships broaden that approach by targeting widely used consumer payment platforms.

Circle Chief Strategy Officer Dante Disparte said South Korea's evolving regulatory framework presents an opportunity rather than a disadvantage. According to his remarks, policymakers can build on lessons learned from stablecoin regulations introduced in the United States, Europe, and the United Kingdom. South Korea has yet to enact comprehensive stablecoin-specific legislation, leaving a framework that companies like Circle hope to help shape.

The company also emphasized that it is not seeking to launch a Korean won-pegged stablecoin. Instead, Circle aims to position USDC alongside future domestic digital currency initiatives.

Kakao has already expanded its blockchain ambitions through Kaia, the network created after the merger involving Klaytn. Meanwhile, growing institutional interest in digital assets continues to encourage collaboration between established fintech companies and blockchain infrastructure providers.

If implemented, the new partnerships could support faster cross-border payments, blockchain settlements, and broader stablecoin adoption across South Korea's digital financial services.
