Line Next and the Kaia DLT Foundation have announced plans to launch Project Unify, a web3 super app powered by Stablecoin, which will enter beta versions later this year.
The platform will debut as a Kaia-powered standalone service and as a mini-dup within Line Messenger. One hub combines Stablecoin yields, payments, remittances, on/off ramps, decentralized finance, and Consumer Web3 applications.
Unify makes payments the top priority as Asia’s Stablecoin Race intensifies

The rollout highlights a wider shift. Digital finance is moving to a platform that consumers already use every day. Rather than pushing another wallet download, the following line and Kaia embedded Unify Inside Line Messenger, one of Asia’s most widely used apps.
“We have seen both the needs and possibilities of stubcoin. We plan to lead the expansion of Asia’s Stablecoin ecosystem by introducing a super app that anyone can use easily and safely.”
– Youngsu Ko, CEO, Line Next
Unify includes real-time “Easy Saver” rewards, allowing users to deposit Stablecoins and earn instant returns. Your Unify Visa card promises a return of up to 5%. Stablecoin payments work with online and offline merchants all over the world. Peer-to-peer forwarding can be done via line messages within one minute.
This service extends the access point. Its wide on/off ramp coverage aims to simplify travel between Fiat and Stubcoin, a permanent hurdle for users. Beyond payments, Unify offers over 100 Web3 apps, including Defi, NFT and games, with additional rewards for engagement.
Next Line and Kaia tested this model in January 2025 by launching the Mini Dup at Line Messenger. They explain that the rollout attracted more than 130 million new registered users. With Line’s 194 million monthly active users in Japan, Taiwan and Thailand, Unify is trying to turn its traction into a complete consumer platform.
Regional stability integration and SDK expansion
Unify aggregates local stubcoins into one framework. It supports tokens pinned in the US dollar, Japanese yen, Korean victory, Thai baht, Indonesian rupiah, Philippine peso, Malaysian ringgit and Singapore dollar. By integrating fragmented payment rails, Kaia is unified as an Asian orchestration layer for issuance, payments and yields.

The next line and Kaia will release the Unify SDK for Stablecoin publishers and developers to expand their reach. Publishers can distribute tokens across the boundaries, but developers can embed payments and gain functionality in the app. It aims to expand the liquidity and practicality of the regional market.
The company emphasized that Unify will adapt to the rules of each jurisdiction. By linking with Line’s DAPP portal, the service can adjust functionality to local regulations. This is an important step in Asia’s diverse legal landscape.
“Project Unify is Kaia’s strategic project to seize opportunities to dominate the Asian stubcoin market. Another core element is the Stablecoin Orchestration Layer. Asia’s payment infrastructure remains highly fragmented and Kaia is uniquely positioned to integrate it and promote fiscal inclusion through borders.”
– Dr. Samsaw, Chairman of the Kaia DLT Foundation
Coinbase Base App vs. Unify: Competing Visions of “All Apps”

Coinbase pursues its own super app vision. Rebranded base apps from Coinbase Wallet bring transaction, payment, messaging and social capabilities to your Layer 2 base network. Includes AI-powered agents, NFC-enabled USDC payments, and “Flashblocks” technology to reduce blocking times from 2 seconds to 200 milliseconds.
In a comment on Beincrypto, Dr. Sam Seo, chairman of the Kaia DLT Foundation, emphasized that it will be unified from the Coinbase model.
“Built on Kaia’s Layer 1 blockchain, Unify integrates with Stablecoin transfers, payments, Dex, and messengers that we already use every day for Mini Apps for Games for NFTS.
– Dr. Sam Seo, Kaia DLT Foundation
SEO said Coinbase’s base app grew from the exchange and wallets of the Western market, and Unify started with Line Messenger. With its foundation, unification can reach hundreds of millions of users and serve as a coordinator for regional stylization.
He also said Unify will expand beyond Kaia’s USDT and include stub coins pinned in currencies such as the Yen, Won, Baht and Ringgit.
“We will integrate plans to combine local stubcoin into a single super app experience using Line’s Reach and Kaia’s network. Featuring Kaia’s Stablecoin orchestration layer, Unify seamlessly delivers payments, Defi and everyday financial services through Line Messenger.”

This contrast shows two paths. Coinbase highlights the speed and social financing of the Western market, with the following line and Kaia focusing on compliance, payments and Asian local currencies. Both want to define the future of Web3 consumer apps, but start with a variety of foundations.
Regulation context and market outlook
Unify’s payment strategy is because regulators are reassessing digital finance. The President’s Working Group on the Digital Asset Market has published a report urging more explicit rules for US digital assets and Stablecoin publishers. Eversheds Sutherland analyzed RePort, which calls for the prompt implementation of the Genius Act, will sign the law in July and create a payment stabilizing licensing system.
In a previous exclusive interview with Beincrypto, Kaia Chairman Dr. Sam Seo emphasized that Asia must prepare a silly of local currency to balance the growing role of USD-promoting tokens based on the Genius Law. He also suggested that the multicurrency Stablecoin Alliance could improve cross-border liquidity and strengthen the region’s financial autonomy.
For Asia, where payment systems remain fragmented, this shift highlights the value of Unify’s orchestration model. By providing compliant and interoperable infrastructure, Unify can open cross-border financial access to both consumers and institutions.
Super App races depend on which models (performance-driven social finance or compliance-driven payment integration).
