LINE NEXT, the U.S.-based blockchain subsidiary of LINE Yahoo, has introduced Unifi Pay, a new stablecoin payment platform designed to make global digital payments faster, cheaper, and easier for businesses and developers.
The company has opened developer pre-registration ahead of the platform’s planned global launch in the third quarter of 2026. Built on the Unifi stablecoin wallet, the service aims to provide near-instant settlements with zero payment fees while supporting multiple stablecoins from day one.
Unifi Pay to Support USDT, JPYC, and IDRP
At launch, Unifi Pay will support three major stablecoins:
- USDT (Tether)
- JPYC, a Japanese yen-backed stablecoin
- IDRP, an Indonesian rupiah-backed stablecoin
Users in Japan and Indonesia will be able to complete identity verification and top up their stablecoin wallets directly from local bank accounts.
LINE NEXT also confirmed plans to introduce additional local stablecoins in other markets as regulations evolve, expanding the platform’s global reach over time.
Zero-Fee Payments With One-Second Settlement
One of Unifi Pay’s biggest selling points is its fee-free payment model.
According to the company, the wallet-based infrastructure allows users and merchants to transact directly without traditional payment processing fees.
The platform also delivers an average settlement time of around one second, making it significantly faster than many conventional payment systems.
This combination of low costs and rapid settlement could make stablecoin payments more practical for both businesses and consumers.
Easy Integration for Developers
LINE NEXT is also targeting developers through the launch of the Unifi Pay SDK.
The software development kit enables businesses, creators, and AI developers to integrate stablecoin payments into their applications with minimal effort.
According to the company, developers can generate a fully functional payment page in approximately 10 minutes using a single command.
The SDK also supports Agent-to-Agent (A2A) task execution, allowing AI agents to automate payment-related processes more efficiently.
Rewards for Businesses Holding Stablecoins
Beyond payment processing, LINE NEXT plans to reward businesses that retain their payment proceeds within the Unifi wallet.
Depending on the stablecoin used, developers and merchants may earn annual rewards of up to 5% on wallet balances.
The reward system is designed to encourage long-term use of the platform while increasing liquidity within the Unifi ecosystem.
Successful Beta Paves the Way
Before announcing the public rollout, LINE NEXT conducted a year-long beta program.
According to the company, the beta processed approximately 100 billion Korean won in cumulative payment and settlement volume.
The successful trial demonstrated growing demand for stablecoin-based payment infrastructure and helped validate the platform ahead of its global release.
Building on Project Unify
The launch of Unifi Pay is part of LINE NEXT’s broader blockchain strategy.
The company has already been working with Kaia through Project Unify, an initiative introduced during Korea Blockchain Week 2025.
Project Unify aims to transform LINE Messenger into a stablecoin-powered super app by combining:
- Digital payments
- Stablecoin wallets
- On- and off-ramp services
- Yield opportunities
- Access to decentralized applications (dApps)
The project is expected to support several regional currencies, including the U.S. dollar, Japanese yen, Korean won, Thai baht, Indonesian rupiah, Philippine peso, Malaysian ringgit, and Singapore dollar.
Expanding Stablecoin Payments Across Asia
LINE Yahoo’s ecosystem already serves hundreds of millions of users across Asia, giving Unifi Pay a significant potential user base.
By combining stablecoin payments with developer-friendly tools and fast settlement speeds, LINE NEXT hopes to create payment infrastructure that supports businesses, creators, AI applications, and digital commerce across multiple countries.
As regulations surrounding digital assets continue to mature, the company plans to expand support for additional local stablecoins and financial services.
The Bottom Line
With the upcoming launch of Unifi Pay, LINE NEXT is positioning itself as a major player in the growing stablecoin payments market.
The platform combines zero transaction fees, near-instant settlement, support for multiple stablecoins, and simple developer integration to create a payment solution designed for the next generation of digital commerce.
Backed by LINE Yahoo’s massive user ecosystem and its ongoing blockchain initiatives, Unifi Pay could play an important role in accelerating stablecoin adoption across Asia and beyond.
