Kaia and LINE NEXT Launch Stablecoin Super-App

Kaia and LINE NEXT are rolling out a stablecoin super-app aimed at unifying Asia’s fragmented markets through LINE Messenger.

Summary

• Kaia and LINE NEXT announced plans to launch Project Unify at KBW 2025.
• The stablecoin super-app integrates payments, remittances, and DeFi into LINE.
• It targets LINE Messenger’s nearly 200 million users, supporting various Asian fiat-pegged stablecoins.

On September 22, during Korea Blockchain Week in Seoul, Kaia announced Project Unify, which aims to provide millions of users in Asia with access to decentralized finance, remittances, and payments. The company describes Project Unify as a “universally compliant” platform that integrates stablecoin payments, yields, on/off-ramps, and access to over 100 decentralized apps directly within LINE Messenger, which boasts almost 200 million monthly active users.

Stablecoin Orchestration for Asia

LINE’s Finschia and Kakao’s Klaytn merged to form Kaia in 2024, branding itself as Asia’s “stablecoin orchestration layer.” With support for currencies like USD, JPY, KRW, THB, IDR, PHP, MYR, and SGD at launch, Project Unify aims to unify the region’s fragmented stablecoin markets.

The platform will provide developers and issuers with tools through a dedicated Unify SDK, emphasizing regulatory compliance, particularly in South Korea. Kaia’s recent trademark filings for a KRW stablecoin suggest the rollout of a won-pegged asset to solidify the ecosystem.

LINE Messenger as the Distribution Layer

With nearly 200 million monthly active users in Japan, Taiwan, Thailand, and Indonesia, LINE Messenger offers the scale necessary for Kaia and LINE NEXT to drive adoption. The app will enable users to pay, earn yield, and access Web3 services without leaving the messenger interface.

This integration comes on the heels of Kaia’s recent regional expansions, including a partnership with Taiwan Mobile and co-hosting of the Wave Stablecoin Summer Hackathon with Tether (USDT), attracting global developers to create DeFi Mini Dapps for LINE’s ecosystem.

If Project Unify succeeds, it could link institutional regulation with retail adoption, making it Asia’s first mass-market, compliant stablecoin platform.

Supported by the distribution power of Kakao and LINE, Kaia’s stablecoin initiatives position it competitively against local fintech giants and aim to establish stablecoins as the foundation of Asia’s digital economy.
