Circle partners with Kakao, Toss on South Korea stablecoin push

Circle has signed separate memorandums of understanding with Kakao Group and South Korean fintech operator Toss to explore stablecoin payments, blockchain settlement and digital asset infrastructure in South Korea.

The agreements bring Circle’s USDC and payment technology into discussions with some of Korea’s largest consumer finance platforms. Kakao, Kakao Pay and Kakao Bank will study opportunities around KRW-based digital assets, cross-border payments and tokenized financial services. Toss and Toss Bank will examine similar uses, including digital wallets, overseas payments and programmable onchain transactions.

Kakao Group said its agreement with Circle will combine the KakaoTalk-centered platform ecosystem with Kakao Pay’s payment services, Kakao Bank’s banking capabilities and Circle’s blockchain infrastructure. The companies plan to review payment, settlement and digital asset connectivity as South Korea develops rules for stablecoins and other tokenized financial products.

The initial work will focus on faster payment and settlement systems, according to local reporting. The companies will also assess cross-border remittances, merchant settlement and links between blockchain networks and existing financial systems. Kakao Group said the infrastructure could eventually support services from other Korean companies, although the MOU does not set a launch date or confirm a specific stablecoin issuance model.

Kakao Pay CEO Shin Won-keun, who leads the group’s stablecoin task force, said the companies would “preemptively prepare a Korean digital asset ecosystem with Circle.” Circle executives met Kakao representatives in Pangyo on July 22 before the partnership was announced.

Toss explores USDC and programmable payments

Circle also signed a separate MOU with Viva Republica, the operator of Toss, and Toss Bank. The companies will study blockchain-based payments and stablecoin infrastructure, with potential uses covering digital wallets, cross-border settlement and financial services that use USDC.

Toss will review biometric payment tools, USDC-linked financial products and programmable onchain payments. Toss Bank will focus on connecting stablecoin infrastructure with traditional bank accounts and fiat payment networks. The parties also plan to examine compliance, risk management, security and anti-money laundering requirements as Korean rules develop.

The agreement builds on Toss’s broader interest in digital assets. As crypto.news previously reported, the fintech has explored a proprietary blockchain and a possible token while preparing for a Korean stablecoin market. Toss Bank has also been studying blockchain-based payment and settlement models.

Circle expands its South Korea strategy

The new agreements follow months of outreach by Circle in South Korea. As crypto.news reported on July 13, the company planned its Current Seoul event to bring banks, exchanges, payment firms and super-app operators together for talks on digital asset regulation and payments. Kakao Pay CEO Shin Won-keun was among the scheduled speakers.

Circle CEO Jeremy Allaire also visited Seoul in April and met executives from Korean banks, exchanges and payment companies. He said Circle did not plan to issue its own won stablecoin. Instead, the company has positioned USDC and its infrastructure as possible links between future KRW-denominated tokens and global payment networks.

That approach is visible in the latest agreements. Circle is not announcing a KRW stablecoin with Kakao or Toss. The companies are studying how local won-based digital assets could work alongside USDC, blockchain settlement systems and existing financial infrastructure. 

Any commercial launch will depend on the final product design and regulatory approvals. Circle Chief Commercial Officer Kash Rajaghi said Korea has “a solid foundation for financial innovation.”

Korean firms prepare for stablecoin rules

South Korean technology and financial groups have increased work on won-based stablecoins as policymakers prepare a broader legal framework. Kakao Bank has already explored stablecoin development, while Kakao Pay has been building a wider group strategy around KRW-linked digital assets.

Kakao Group said its Circle partnership could support a shared foundation for stablecoin services beyond its own platforms. The group is also reviewing tokenized financial services, which could use stablecoins as a settlement layer when assets move between blockchain networks and traditional financial systems.

Circle has taken a similar infrastructure-led approach elsewhere in Asia.The company recently partnered with Japan’s JCB to test USDC for corporate treasury transfers and merchant payments. The Korean agreements extend that regional strategy into platforms with large domestic payment and banking networks.

For now, both partnerships remain exploratory. Kakao Group, Toss and Circle have not announced a launch date for a KRW stablecoin or a live consumer payment product. Their agreements instead create a framework to test business models, technical connections and regulatory requirements as South Korea’s digital asset rules take shape.
