LINE NEXT Partners with Tether: Mini Dapps Now Support USDT Payments and Transfers

·

The Web3 landscape in Asia is taking a major leap forward as LINE NEXT Corporation (LINE NEXT), a subsidiary of LINE dedicated to building a decentralized ecosystem, announces a strategic collaboration with Tether, the world’s leading stablecoin issuer. This partnership introduces native USD₮ (USDT) integration on the Kaia blockchain, powering seamless, fast, and secure digital transactions within LINE’s vast user base.

By deploying USD₮ natively on Kaia—a high-performance public blockchain developed by LINE NEXT—the collaboration brings dollar-pegged stablecoin functionality directly into mainstream consumer applications. Users can now conduct instant payments and transfers using USDT through Mini Dapps embedded in the LINE Messenger app, marking a pivotal step toward mass Web3 adoption.

Seamless Stablecoin Integration in Everyday Messaging

With this integration, USD₮ becomes fully accessible via the built-in wallet in LINE Messenger. Users no longer need external wallets or complex setups to engage with decentralized applications. Whether making peer-to-peer transfers, paying for digital goods, or participating in reward programs, everything happens within the familiar environment of LINE.

Mini Dapps—lightweight decentralized applications running on the Kaia network—are now enhanced with native USDT support, enabling frictionless transactions across gaming, social media, content platforms, and more. These apps are accessible directly through the Dapp Portal inside LINE or via official LINE accounts, eliminating the need to download separate apps.

Since its launch in January 2025, the Mini Dapp ecosystem has seen explosive growth, surpassing 35 million cumulative users across key markets including South Korea, Japan, Taiwan, and Thailand—proving that convenience and familiarity drive Web3 adoption at scale.

Empowering Users with Dollar-Backed Digital Transactions

Stablecoins like USD₮ play a critical role in reducing volatility and enabling reliable value transfer in digital economies. By anchoring transactions to the U.S. dollar, LINE NEXT ensures users experience predictable pricing and trustless settlement—key factors for everyday usability.

The integration also paves the way for task-based reward systems where users earn USDT for engaging with Mini Dapps. This gamified approach lowers the barrier to entry for new users exploring Web3, turning routine interactions into opportunities for financial participation.

"Adopting USD₮ helps establish a dollar-based transaction gateway in Asia," said Young-Su Ko, CEO of LINE NEXT. "By integrating stablecoin services, we aim to bring Web3 applications closer to users' daily lives."

Why Kaia? Speed, Scalability, and Ecosystem Reach

Kaia stands out as one of the most advanced EVM-compatible blockchains in Asia, combining low-latency transactions with instant finality. As a merged entity of Kakao’s Klaytn and LINE’s Finschia blockchains, Kaia leverages years of development and user trust from two of Asia’s largest super apps: KakaoTalk and LINE.

With over 250 million combined users, Kaia offers unmatched reach for decentralized services. Its infrastructure supports both DeFi (decentralized finance) and CEX (centralized exchange) platforms, ensuring that USD₮ transactions are not only fast but interoperable across a wide range of financial tools.

Dr. Sam Seo, Chairman of the Kaia DLT Foundation, emphasized the significance of the partnership:

"Our collaboration with Tether accelerates the adoption of high-quality, dollar-backed stablecoins across Asia. With Kaia’s industry-leading transaction speed and finality, USD₮ delivers the fastest, most reliable experience for DeFi and CEX users alike."

Tether’s Vision: Bringing Stability to Mass Markets

For Tether, this move represents a strategic expansion into one of the world’s most dynamic digital economies. As the largest and most transparent issuer of stablecoins, Tether continues to bridge traditional finance with decentralized innovation.

Paolo Ardoino, CEO of Tether, stated:

"Native issuance of USD₮ on the Kaia blockchain is a crucial step in bringing stablecoins to hundreds of millions of mainstream users. This partnership demonstrates our shared commitment to advancing financial inclusion across Asia and beyond."

This deployment aligns with Tether’s broader mission to build resilient financial infrastructure using blockchain technology—supporting everything from remittances to AI-driven economies.
