[First in Japan] JPYC Stablecoin Now Available on Unifi Wallet, Accessible Through the LINE App

JPYC Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; CEO: Noritaka Okabe), the company behind the Japanese Yen stablecoin 'JPYC,' is pleased to announce that JPYC has been officially adopted and is now available on 'Unifi,' a web3 wallet launched by LINE NEXT Inc., a group company of LINE Yahoo Corporation focused on global web3 business.

This development is expected to create an unprecedented new experience in payments, remittances, rewards, and interest, combining the high security of a 'non-custodial' (self-managed) model with the utility of a Japanese Yen stablecoin, accessible from the LINE app used by over 100 million people in Japan. Furthermore, the use of JPYC on the Kaia network via the LINE app is the first of its kind in the country.

## Background of the Integration

With this official launch, users can now instantly use the price-stable Japanese Yen stablecoin 'JPYC' through 'Unifi.' An environment where users can manage the value of their stablecoins with intuitive operations, without being conscious of complex blockchain technology, and perform payments, transfers, and deposits is scheduled to be progressively implemented in society.

By operating on the widely used LINE app, it opens up the web3 experience, previously limited to a niche audience, to the masses, providing a new financial experience of handling digital money with the same ease as sending a message.

## Four User Benefits Planned by Unifi × JPYC

- **Seamless User Experience**: A comprehensive experience from wallet creation to payment, transfer, deposit, and reward reception will be sequentially offered entirely within the LINE app. The UI/UX, which abstracts away the blockchain, allows for smooth operation by anyone.
- **High Extensibility for Daily Payments**: As JPYC is denominated in Japanese Yen, it can be used for everyday payments and transfers. It can also support a wide range of uses, such as purchasing digital content and community rewards.
- **Security through Self-Management (Non-Custodial)**: The model allows users to manage their own private keys, rather than entrusting assets to a third party.
- **No Additional App Installation Required**: Wallet creation is completed within the everyday LINE app, eliminating the need for new app downloads or complex initial setups.

## About Unifi: A Next-Generation Web3 Experience on the LINE App

'Unifi' is a non-custodial wallet that can be used instantly with just a LINE account. It eliminates the complex processes inherent in traditional self-managed wallets, achieving overwhelming convenience by being 'usable in the fewest steps without leaving the LINE app.' Unifi is also planned to be offered separately as a mini-app within the LINE app in Japan, allowing a broader range of users to engage with JPYC in a familiar environment. A JPYC rewards campaign for Japanese users is scheduled to start on Unifi today.

## About the Start of JPYC Issuance on the Kaia Network

As of May 15, 2026, JPYC has officially begun issuance on the 'Kaia' blockchain, one of Asia's largest web3 ecosystems.

KAIA is a leading high-performance public blockchain in Asia with a potential user base of over 250 million. This issuance will provide users with the following value:

- **Overwhelming Operational Speed and Convenience**: Achieves processing speeds and usability comparable to web2 messenger services.
- **Optimized Payment Experience for Japanese Users**: Using a stablecoin (JPYC) linked to the familiar 'Japanese Yen' mitigates price volatility risk for everyday transfers and payments.
- **Participation in a Global Ecosystem**: Deepens collaboration with various domestic and international web3 services and decentralized applications through the Kaia network, expanding JPYC's use cases.
