Tether Launches USDT on Kaia Blockchain, Integrates with LINE Mini Dapps

·

Tether, the issuer of the world’s most widely used stablecoin USDT, has officially launched its native token on Kaia, a Layer 1 blockchain introduced in August 2024. This strategic deployment marks a significant step toward expanding digital dollar adoption across Asia, particularly within the expansive ecosystem of LINE, one of the region’s most popular messaging platforms.

The integration enables seamless use of USDT within LINE’s Mini Dapps and its self-custodial wallet, allowing over 200 million active users to engage in real-time transactions such as in-app payments, cross-border remittances, and decentralized finance (DeFi) activities—all without leaving the familiar LINE Messenger interface.

Expanding Digital Dollar Access in Asia

Tether’s move to deploy USDT natively on Kaia is more than just a technical upgrade—it’s a gateway to mainstream financial inclusion. With this launch, users can now earn rewards in USDT through various tasks within Mini Dapps, send and receive dollar-pegged digital assets instantly via LINE’s in-app wallet, and participate in Web3 applications with minimal friction.

“Tether’s stablecoin will support Mini Dapps and more, ushering in a new era of digital dollar usage in Asia.”

This initiative aligns with LINE NEXT’s vision of building a “dollar corridor” in Asia—a trusted, efficient channel for digital dollar transactions that leverages blockchain technology while maintaining user accessibility. According to Youngsu Ko, CEO of LINE NEXT, the partnership aims to make digital assets an integral part of daily life for millions across Japan, South Korea, and Southeast Asia.

Paolo Ardoino, CEO of Tether, emphasized the broader implications:

“Native deployment of USDT on Kaia represents another leap toward bringing stablecoins to millions of mainstream users. With LINE NEXT’s robust blockchain infrastructure, over 200 million LINE users can now easily interact with digital assets in their everyday lives.”

Seamless Integration with LINE's Ecosystem

The collaboration between Tether and LINE NEXT unlocks powerful use cases:

All these features operate within the secure and user-friendly environment of LINE Messenger, significantly lowering the barrier to entry for non-crypto-native users.

This integration also enhances the utility of Kaia Chain, which was designed specifically to support high-throughput, low-latency applications tailored for mass-market adoption. By anchoring USDT as a primary settlement asset, Kaia strengthens its position as a leading blockchain infrastructure provider in the Asian market.

Driving Web3 Adoption Through Familiar Platforms

One of the biggest challenges in Web3 adoption has been usability. Most blockchain applications remain complex and intimidating to average consumers. By embedding USDT functionality directly into LINE—a platform already used for messaging, shopping, and social networking—Tether and LINE NEXT are effectively bridging the gap between traditional internet experiences and decentralized finance.

Users no longer need to navigate separate crypto wallets or understand private keys. Instead, they interact with digital assets through intuitive interfaces they already trust. This “invisible onboarding” model could serve as a blueprint for future Web3 integrations across other consumer platforms.

Moreover, the partnership fosters innovation among developers building on Kaia. With access to a ready-made user base and a stable transactional currency (USDT), developers can focus on creating compelling experiences rather than worrying about liquidity or payment rails.

Strategic Momentum Behind Tether’s Growth

The Kaia deployment follows closely on the heels of Tether minting an additional $1 billion USDT on the Tron network** on May 5, 2024—bringing the total supply on Tron to **$71.4 billion. Meanwhile, USDT circulation on Ethereum has reached $72.8 billion, underscoring sustained demand across multiple blockchains.

Tether also reported $1 billion in operating profit during Q1 2025, driven primarily by strong returns from its U.S. Treasury investments. This financial strength reinforces confidence in the stability and sustainability of USDT, especially amid growing scrutiny of stablecoin reserves globally.

These developments reflect Tether’s dual strategy:

  1. Expanding supply to meet rising global demand.
  2. Deepening integration into high-traffic ecosystems like LINE to drive real-world usage.

Frequently Asked Questions (FAQ)

Q: What is Kaia Blockchain?
A: Kaia is a Layer 1 blockchain launched in August 2024, optimized for high performance and ease of use. It powers LINE’s Web3 initiatives and supports native deployment of major cryptocurrencies like USDT.
