Tether Expands Its USD₮ Stablecoin to Line's Mini DApp Ecosystem

As part of a broader collaboration with Line Next, the Web3 arm of Line

Tether, the issuer of the largest stablecoin, USDt, has announced the integration of its flagship token with Line Next, the Web3 arm of Japan’s popular messaging platform, Line.

The partnership will see USDt (USDT) deployed on the Kaia blockchain, which powers Line’s Mini DApps and is used by over 196 million people monthly.

The integration means USDt will now be supported across Line’s messenger-based Mini DApp ecosystem and self-custodial wallet, enabling users to interact with stablecoins inside an interface they already use daily, Tether said in a Monday announcement.

Line users will be able to use USDt for in-app payments, cross-border transfers and decentralized finance (DeFi) activities.

“Through LINE NEXT’s blockchain infrastructure, over 200 million LINE users will now have a straightforward way to engage with digital assets in everyday life,” Tether CEO Paolo Ardoino said.

Ardoino added that this partnership will introduce "the fastest, easiest, and most reliable USDT experience" to users across platforms like LINE, DeFi apps, and centralized exchanges.

The partnership will also create a "dollar-based gateway" for users, making Web3 services more practical and accessible for the region's everyday consumers, according to Line Next CEO Youngsu Ko.

The Kaia DLT Foundation chair, Sam Seo, also highlighted the advantages of the Kaia chain, which offers low-latency transactions and immediate finality, making it a strong partner for stablecoin activity.

Initial features will include mission-based USDT rewards within Mini DApps and peer-to-peer USDT transfers via Line’s in-app wallet. Future additions may expand stablecoin functionality across other app layers.

Tether’s USDT is the largest stablecoin in terms of market capitalization, with a circulating supply of over 149.4 billion tokens, according to data from CoinMarketCap.

The stablecoin issuer has also been consistently minting new tokens. On May 5, Tether minted another $1 billion USDT on the Tron network, bringing the total USDT on Tron to $71.4 billion.

In comparison, there is currently $72.8 billion USDT circulating on the Ethereum network.

On May 6, Tether announced a partnership with Chainalysis that will integrate the company’s compliance and monitoring tools onto Tether’s tokenization platform. The move comes amid expanding oversight across the crypto industry.
