Layer 1 blockchain Kaia and LINE NEXT, the Web3 arm of messaging giant LINE, announced Monday that they plan to launch "Project Unify," a stablecoin superapp set to debut on LINE's Dapp Portal later this year.

In a Monday statement shared with The Block, Kaia said the Unify service aims to combine consumer payments, remittances, and on- and off-ramps into a single interface. The company added that users would be able to deposit stablecoins to earn real-time incentives, transfer funds via messages, and make online and in-store payments worldwide with spending rewards.

The pair noted that they plan to offer a companion Unify software development kit (SDK) to target two groups: stablecoin issuers, who could distribute across borders to build liquidity and utility, and app developers, who could embed stablecoin features within their products.

The Unify app is scheduled to launch its beta later this year, offered both as a Kaia-powered standalone service and as a Mini Dapp run by LINE NEXT, according to the statement. It is designed to support stablecoins tied to the U.S. dollar and other major currencies, including the Japanese yen, Thai baht, Korean won, Indonesian rupiah, Philippine peso, Malaysian ringgit, and Singapore dollar. 

The announcement builds on the companies' January 2025 launch of Mini Dapps, which they said has attracted more than 130 million new registered users to date.

"We have seen both the needs and the potential of stablecoins," said Youngsu Ko, CEO of LINE NEXT. "We plan to lead the expansion of Asia’s stablecoin ecosystem by introducing a superapp that anyone can use easily and safely."

Sam Seo, chairman of the Kaia DLT Foundation, said another key element is the stablecoin orchestration layer, noting that Asia’s payment infrastructure "remains highly fragmented," and that Kaia aims to "consolidate it and drive cross-border financial inclusion."

Kaia was launched in April 2024 through the merger of Kakao’s Klaytn and LINE’s Finschia blockchains. Kakao operates South Korea’s dominant messaging app, while LINE is a major messaging platform in markets including Japan, Taiwan and Thailand.
