The Kaia stablecoin super app actually launched through Project Unify, which is a collaboration between Kaia and LINE Next that’s targeting Asia’s digital payment infrastructure right now. This cross-border stablecoin payments platform was unveiled at Korea Blockchain Week 2025, and it integrates stablecoin services under Asia stablecoin regulations for LINE Messenger’s nearly 200 million users.

The Kaia stablecoin super app operates as Asia’s first universally compliant stablecoin platform within LINE Messenger, which is pretty significant. Kaia emerged from the 2024 merger of Klaytn and Finschia blockchains and now powers Project Unify’s cross-border stablecoin payments infrastructure.

Project Unify combines payments, remittances, DeFi access, along with cross-border stablecoin payments through a single interface, targeting the region’s fragmented payment systems that have been problematic for users.

Youngsu Ko, CEO of LINE Next, had this to say:

“We have seen both the needs and the potential of stablecoins. We plan to lead the expansion of Asia’s stablecoin ecosystem by introducing a super-app that anyone can use easily and safely.”

Multi-Currency Support and Regional Integration

The Kaia stablecoin super app supports eight regional currencies including USD, JPY, KRW, THB, IDR, PHP, MYR, and SGD at launch, which covers most of Asia’s major markets. This Line Next stablecoin infrastructure addresses Asia stablecoin regulations by providing compliant cross-border stablecoin payments across different jurisdictions, even as regulatory frameworks continue to evolve.

Dr. Sam Seo, Chairman of Kaia DLT Foundation, stated:

“Project Unify is Kaia’s strategic project to seize the opportunity in dominating the Asian stablecoin market… Another core element is the stablecoin orchestration layer—Asia’s payment infrastructure remains highly fragmented, and Kaia is uniquely positioned to consolidate it and drive cross-border financial inclusion.”

The platform offers real-time yield through “Easy Saver” rewards and also includes a Unify Visa card with up to 5% payback. Users can actually complete peer-to-peer transfers through LINE messages in under one minute, while accessing over 100 Web3 applications including DeFi, NFTs, and some gaming platforms as well.
