On September 22, Layer 1 blockchain Kaia and LINE NEXT, the Web3 subsidiary of messaging giant LINE, announced plans to launch Project Unify. The initiative will introduce a stablecoin super-app on LINE Messenger later this year, providing nearly 200 million monthly users across Japan, Taiwan, and Thailand with access to payments, remittances, and cryptocurrency services on a single platform.
Project Unify Combines Payments, Remittances, & Crypto On/Off-Ramps
The announcement took place during Korea Blockchain Week in Seoul, where Kaia and LINE NEXT outlined their vision for Project Unify. The app is designed as a universally compliant solution that simplifies cross-border money use under a single interface.

A beta launch is scheduled for later this year. Project Unify will appear both as a standalone Kaia-powered app and as a Mini Dapp inside LINE Messenger.
The dual model expands reach, ensuring adoption among LINE’s existing user base while also serving as an independent financial tool.
The super-app will support stablecoins linked to major currencies, including the U.S. dollar, Japanese yen, Thai baht, Korean won, Indonesian rupiah, Philippine peso, Malaysian ringgit, and Singapore dollar.
Users will be able to deposit stablecoins and earn instant rewards, transfer money across borders as easily as sending a message, and make purchases both online and in stores with access to global spending benefits.
Kaia and LINE NEXT also emphasized tools for developers and issuers. A Unify software development kit will allow stablecoin issuers to distribute tokens across multiple regions to improve liquidity.
At the same time, app developers will be able to integrate stablecoin functions into their own platforms, from games to online marketplaces.
Stablecoin Adoption Gains Global Momentum
Project Unify’s timing coincides with rapid growth in the stablecoin sector. In April 2025, the U.S. Treasury projected that the $295 billion market could swell to $2 trillion by 2028.
This outlook has shifted the approach of governments, businesses, and innovators toward digital currencies.
In South Korea, lawmakers are preparing a bill expected in October to regulate how won-pegged stablecoins are issued, backed, and managed.
In the United States, President Trump signed the Genesis Act, which requires full reserve backing, monthly audits, and strict anti-money laundering checks.
Private companies are also moving quickly. PayPal has expanded its stablecoin, PYUSD, to eight more blockchains, adding support beyond Ethereum to networks such as Solana, Arbitrum, Tron, Avalanche, Aptos, and Stellar. At the same time, interest from large corporations is climbing.

Adoption is also rising among major businesses. A recent survey shows that nearly 29% of Fortune 500 executives now plan to use stablecoins, a sharp rise from just 8% last year.
By combining payments, remittances, stablecoin yields, and crypto on- and off-ramps in one platform, Project Unify enters a market where regulation, innovation, and adoption are aligning.
Its reach through LINE Messenger’s 200 million users places Kaia and LINE NEXT in a strong position to shape the next stage of digital finance.
