AdvanceAbility Announces Development of 'JPYC Subscription Service,' a Payment Infrastructure for JPY Stablecoin

AdvanceAbility Co., Ltd. (Headquarters: Yatsushiro City, Kumamoto Prefecture; CEO: Mutsuo Mitsugiri) has announced the conceptual plan for 'JPYC Subscription Service (tentative name),' a subscription payment infrastructure utilizing the Japanese Yen stablecoin 'JPYC.'

This service independently develops the JPYC subscription functions previously verified in the company's internal services, providing recurring billing features to external businesses in the form of APIs and SDKs. It aims to realize an infrastructure where businesses can easily implement continuous billing based on JPY-denominated stablecoins.

### Background of Development
While the global market for stablecoin payments is expanding, with services using USDC emerging overseas, infrastructure for recurring billing using JPY-denominated stablecoins has not yet become widespread in Japan. This has created a high barrier for Web3 service providers. In response to the growing popularity of 'JPYC' and the increasing need for JPY-denominated on-chain payments, AdvanceAbility is moving forward with this next-generation recurring billing platform.

### About 'JPYC Subscription Service'
The service is a payment infrastructure that allows businesses to integrate JPYC recurring billing on an API basis. By using the planned Checkout SDK and REST API, businesses can efficiently implement wallet connection, Permit signing, subscription management, payment status tracking, and Webhook notifications.

### Key Feature: Gasless Subscription Experience
Users can set up recurring payments with JPYC simply by signing in their wallet. This eliminates gas fees and complex on-chain operations for the user, achieving a UX close to Web2 services.

**Adoption of EIP-2612 Permit**
The service plans to adopt the Ethereum standard 'EIP-2612 Permit.' This will enable:
- Improved UX through off-chain signing
- Gasless approval amounts
- Permission management with expiration dates

### Flexible Integration via API/SDK
Planned features include:
- Checkout SDK
- Subscription API
- Customer and Plan Management
- Permit Management
- Webhook Notifications
- Auto-retry function

Target industries include digital content, creator communities, Web3 SaaS, and membership services.

### Regulatory Compliance Policy
Compliance with the amended Payment Services Act is crucial for stablecoin services in Japan. AdvanceAbility positions legal compliance as a top priority. The service adopts a 'pass-through' architecture where funds are sent directly from the user's wallet to the merchant's wallet, ensuring the service provider does not hold user assets. The company is also consulting with legal experts and regulatory authorities to build a proper operational structure.

### Future Outlook
AdvanceAbility plans to proceed in stages, starting with a closed beta, followed by the release of the Checkout SDK, multi-chain support, Account Abstraction integration, and social login implementation.
