Kakao Partners With Circle to Build Stablecoin and Blockchain Payment Infrastructure

South Korean technology giant Kakao Group has teamed up with stablecoin issuer Circle Internet Financial to develop blockchain-based payment systems and explore infrastructure for won-pegged stablecoins. The strategic partnership comes as South Korea prepares to establish a comprehensive regulatory framework for digital assets and stablecoins.

Under a memorandum of understanding (MOU) announced on Thursday, Kakao and its key financial affiliates, Kakao Pay and Kakao Bank, will collaborate with Circle to integrate blockchain technology and global payment rails into Kakao’s consumer platforms. The joint initiative will focus on stablecoin-based payments, cross-border remittances, merchant settlements, and linking traditional financial systems with decentralized networks. The companies are also looking into tokenized financial services, though specific product details and launch timelines have not been made public.

Kakao Group occupies a dominant position in South Korea’s digital landscape. Its messaging application, KakaoTalk, is used by the vast majority of the country’s population, while Kakao Bank and Kakao Pay have significantly altered retail banking and digital payments in the country. Partnering with Circle, the issuer of the USD Coin (USDC) stablecoin, signals a major push by South Korean tech firms to secure an early foothold in the emerging programmable money sector.

The collaboration highlights how major South Korean financial and technology platforms are positioning themselves ahead of anticipated stablecoin legislation. South Korean authorities are currently drafting laws to govern won-backed stablecoins, aiming to foster financial innovation while managing systemic risks associated with reserve assets, redemption mechanisms, and issuer compliance.

However, progress on the legislation has faced hurdles due to regulatory disagreements. The Bank of Korea, the nation’s central bank, has advocated for a model where traditional commercial banks hold a majority stake in stablecoin issuers to ensure stability. Conversely, the Financial Services Commission (FSC) has cautioned that overly restrictive licensing requirements could stifle competition and limit technological innovation. In its economic growth strategy released on July 14, the South Korean government indicated that advancing the Digital Asset Basic Act is slated for the second half of 2026.

Despite the regulatory delays, South Korean financial institutions are actively testing blockchain integrations. In April, internet-only lender Kbank partnered with Ripple to explore blockchain-powered remittance solutions. Shortly after, in May, KB Financial Group completed a pilot program testing stablecoin issuance, offline merchant transactions, and cross-border transfers on the Kaia blockchain network, preparing for commercial rollout once the legal framework is finalized.
