Circle Signs MOUs with Kakao and Toss to Explore USDC and Won-Linked Payments in South Korea

Circle moves deeper into South Korea’s payments ecosystem with two new MOUs, aligning its USDC infrastructure with Kakao Group and fintech heavyweight Toss to explore won-linked stablecoins, blockchain settlement and digital-asset payments. What was announced - Circle signed separate memorandums of understanding with Kakao Group (including Kakao Pay and Kakao Bank) and Viva Republica (operator of Toss) along with Toss Bank. The partnerships will evaluate use cases for USDC and won-denominated digital assets across payments, settlements, digital wallets and tokenized financial services. - Both MOUs are exploratory: no launch dates, no confirmed issuance model for a KRW stablecoin, and any commercial rollouts will depend on product design and regulatory approval in Korea. What the partners will study - Kakao + Circle: The teams will assess faster payment and settlement rails, cross-border remittances, merchant settlement, and links between blockchain networks and Korea’s incumbent financial systems. Kakao said the collaboration would bring together KakaoTalk’s platform reach, Kakao Pay’s payments and Kakao Bank’s banking capabilities with Circle’s blockchain stack. Kakao Pay CEO Shin Won-keun—who leads the group’s stablecoin task force—said the partners aim to “preemptively prepare a Korean digital asset ecosystem with Circle.” Circle executives met Kakao representatives in Pangyo on July 22 ahead of the announcement. - Toss + Circle: Toss and Toss Bank will explore blockchain-based wallets, biometric payment tools, USDC-linked financial products, programmable on-chain payments and the technical links needed to connect stablecoin infrastructure to traditional bank accounts and fiat networks. The parties will also review compliance, risk management, security and anti-money laundering requirements as Korean rules evolve. How Circle positions USDC Circle is not announcing a KRW-denominated stablecoin with either partner. Instead, it is pitching USDC and its payment/settlement infrastructure as a bridge that could interoperate with future won-based tokens and global payment rails. Circle CEO Jeremy Allaire has been active in Seoul this year—meeting Korean banks, exchanges and payments firms in April—and the company held a Current Seoul event to convene industry players on digital-asset regulation and payments. Circle Chief Commercial Officer Kash Rajaghi said Korea has “a solid foundation for financial innovation.” Regulatory backdrop and wider context South Korean policymakers are working on a broader legal framework for stablecoins and tokenized financial products, and major local groups have been preparing for a won stablecoin market. Kakao Bank and Kakao Pay have previously looked into KRW-linked digital assets, while Toss has explored its own blockchain architecture and a potential token as it positions for a stablecoin future. Circle’s MOUs follow months of outreach in the market and mirror its infrastructure-first approach elsewhere in Asia—such as a USDC pilot with Japan’s JCB for corporate treasury transfers and merchant payments. Bottom line These agreements create a testing ground for business models, technical integrations and regulatory compliance—but they remain exploratory. The MOUs lay the groundwork for how USDC and won-based digital assets might coexist inside two of Korea’s largest consumer finance ecosystems, while any live consumer products will hinge on final product choices and regulatory sign-off.
