<p>Kaia, the Layer 1 blockchain formed from the merger of Kakao’s Klaytn and LINE’s Finschia, and LINE NEXT, the Web3 subsidiary of messaging giant LINE, announced plans Monday to launch a stablecoin “superapp” later this year. The service, called Project Unify, will integrate payments, remittances, and fiat on- and off-ramps into a single interface accessible via LINE’s decentralized app portal.</p>
<p>The app will allow users to deposit stablecoins for yield incentives, transfer funds through chat messages, and make both online and in-store purchases while earning spending rewards. According to the companies, the platform is designed to make stablecoins “usable in everyday life” for mainstream users, expanding beyond speculative trading into payments and commerce.</p>

 Project Unify represents a major push to normalize stablecoin use in Asia, leveraging LINE’s 130M+ user base and Kaia’s blockchain to create a cross-border payments and remittances ecosystem.

<h2 id="developer-and-issuer-integration">Developer and Issuer Integration</h2>
<p>Alongside the superapp, Kaia and LINE NEXT will launch a companion software development kit (SDK) aimed at stablecoin issuers and app developers. Issuers will be able to distribute coins across borders to boost liquidity and adoption, while developers will be able to embed stablecoin functionality directly into apps. This orchestration layer is intended to unify what Kaia’s Sam Seo called Asia’s “highly fragmented” payments infrastructure, offering developers standardized tools to integrate with multiple stablecoins and fiat currencies.</p>
<p>The beta rollout will be offered in two formats: as a standalone Kaia-powered application and as a Mini Dapp integrated within LINE NEXT’s decentralized app platform. Supported currencies will include U.S. dollar-pegged tokens as well as regional stablecoins tied to the Japanese yen, Korean won, Thai baht, Indonesian rupiah, Philippine peso, Malaysian ringgit, and Singapore dollar. This multi-currency model underscores the companies’ ambition to address Asia’s diverse and cross-border financial needs.</p>
<h2 id="building-on-line-s-mini-dapp-ecosystem">Building on LINE’s Mini Dapp Ecosystem</h2>
<p>Project Unify builds on the success of LINE NEXT’s Mini Dapps, introduced in January 2025. That initiative has already drawn more than 130 million registered users, highlighting LINE’s power as a distribution channel for new Web3 services. By leveraging this existing ecosystem, Kaia and LINE NEXT expect strong adoption momentum for Project Unify, particularly in markets where LINE and Kakao dominate the messaging landscape.</p>
<p>“We have seen both the needs and the potential of stablecoins,” said Youngsu Ko, CEO of LINE NEXT. “We plan to lead the expansion of Asia’s stablecoin ecosystem by introducing a superapp that anyone can use easily and safely.” The emphasis on user-friendliness reflects a strategy to differentiate the service from technically complex crypto wallets and exchanges, targeting mainstream retail adoption.</p>

 By embedding stablecoin payments into LINE’s messaging and app ecosystem, Project Unify could accelerate Web3 adoption at scale, much like WeChat Pay did for mobile wallets in China.

<p>LINE, owned by South Korea’s Naver, is a dominant messenger in Japan, Taiwan, and Thailand, while Kakao operates South Korea’s most widely used chat platform. Their blockchain merger into Kaia in April 2024 consolidated two major Asian crypto initiatives, creating a foundation for cross-border digital finance infrastructure. With Project Unify, the companies aim to capitalize on that base by offering a practical, everyday use case for stablecoins in one of the world’s most active messaging networks.</p>
<p>Sam Seo, chairman of the Kaia DLT Foundation, said the orchestration layer will be critical in addressing the fragmented payments landscape in Asia, where multiple fiat currencies and limited interoperability often complicate digital payments. “Stablecoins can solve for speed, efficiency, and transparency across borders,” Seo said, framing the superapp as a solution not just for retail consumers but also for businesses and financial institutions seeking streamlined settlement.</p>
