Tether Brings USDt to Kaia Blockchain, Unlocking Stablecoin Use for 196M LINE Users in Asia

Tether, issuer of the world’s largest stablecoin USDt, has officially deployed its token on the Kaia blockchain in partnership with Line Next—the Web3 arm of LINE, Japan’s leading messaging platform with over 196 million monthly active users. Announced on May 7, the move integrates USDt into LINE’s Mini DApp ecosystem and self-custodial wallet, creating a seamless pathway for everyday stablecoin usage.

This strategic rollout will allow users to utilize USDt for a wide range of activities, including in-app payments, peer-to-peer transfers, and decentralized finance (DeFi) applications—all accessible directly through LINE’s familiar interface.

Tether CEO Paolo Ardoino emphasized the importance of this integration, saying it “underscores [Tether’s] commitment to fostering stablecoin adoption across Asia and beyond.” He noted that Kaia’s infrastructure simplifies user access to digital assets, making them more practical for daily transactions.

Initial features include mission-based USDt rewards via LINE Mini DApps and wallet-based peer transfers. The roadmap may later expand USDt utility to additional parts of LINE’s platform.

The Kaia blockchain, which underpins LINE’s DApp ecosystem, is designed for speed and scalability with low-latency and instant finality—key traits for handling stablecoin-based transactions. Sam Seo, chair of the Kaia DLT Foundation, said the collaboration aims to deliver “the fastest, easiest, and most reliable” USDt experience across messaging apps, DeFi services, and centralized exchanges.

Line Next CEO Youngsu Ko added that the integration will help establish a “dollar-based gateway” for consumers across Asia, making Web3 experiences more accessible and integrated into daily life.

USDt continues to dominate the stablecoin market, with a circulating supply of over 149.4 billion tokens. Tether recently minted $1 billion in new USDT on the Tron network on May 5, raising its Tron-based supply to $71.4 billion—just slightly below its Ethereum supply of $72.8 billion.

Tether also announced a compliance-focused partnership with Chainalysis on May 6, integrating monitoring tools into its tokenization platform amid growing regulatory scrutiny in the crypto space.
