The Kaia DLT Foundation announced the official mainnet launch of the Japanese yen-pegged stablecoin JPYC on the Kaia blockchain to target cross-border remittances and settlements across Asia. The integration follows a separate pilot program by South Korea’s KB Financial Group, which utilized the same network to test a South Korean won-denominated stablecoin for offline payments and international transfers.
JPYC Launches on Kaia Blockchain
The launch occurs roughly seven months after JPYC Inc. secured its Japanese fund transfer license and began its initial issuance in August 2025. According to a joint corporate statement, the integration aims to expand user access and secure global liquidity in markets with rising demand for yen-pegged stablecoins, including South Korea, Indonesia, Thailand, and Taiwan.
The Kaia network, an Ethereum Virtual Machine (EVM)-compatible Layer 1 blockchain, was established through the merger of Kakao’s Klaytn and LINE’s Finschia networks. The platform utilizes a combined infrastructure base of over 250 million users from the Kakao and LINE messaging applications.
Limits Updated as Web3 Wallet Support Begins
In conjunction with the blockchain launch, JPYC Inc. modified its issuance parameters on the JPYC EX platform. The entity changed its prior limit from 1 million yen per day to 1 million yen per transaction, noting that successive short-term requests will remain capped to ensure compliance with Japan’s Payment Services Act.
The company reported that its active accounts surpassed 18,000 as of May 2026, with cumulative issuance reaching 2.5 billion yen and total trading volume exceeding 35 billion yen. Following the integration, LINE NEXT announced that its stablecoin wallet service, Unifi, will add native support for JPYC starting May 22, 2026, allowing users to store the asset without installing separate applications.
KB Financial Group Completes Won Stablecoin Pilot
Separately, KB Financial Group, the parent entity of South Korea’s largest lender KB Kookmin Bank, finalized a pilot program testing a South Korean won stablecoin on the Kaia network. Conducted alongside electronic payments firm KG Inicis and fintech company OpenAsset, the trial tested the lifecycle of the digital asset across issuance, merchant settlement, and remittances.
During the remittance trial, the won-denominated stablecoin was converted into a U.S. dollar stablecoin and transferred to a bank account located in Vietnam. A Kaia spokesperson stated that the international transfer concluded in under three minutes, resulting in an 87% reduction in transaction fees compared to the standard SWIFT network.
Commercial Testing and Regulatory Outlook
The offline payment portion of the KB Financial pilot was conducted at the Seoul-based coffee franchise Hollys, where participants completed transactions via QR codes without installing dedicated cryptocurrency wallets. KB Financial stated it intends to launch commercial stablecoin services once South Korea establishes formal digital asset regulations.
The progression of the country’s Digital Asset Basic Act remains paused due to jurisdictional disagreements between the Bank of Korea and the Financial Services Commission regarding stablecoin issuance ownership. Legislative deliberations are expected to remain on hold until after South Korea’s local elections in June.
