JPYC Co., Ltd. Launches 'JPYC EX Integration API' for Wallet and JPYC-Utilizing Services

JPYC Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Noritaka Okabe; hereinafter "the Company") announces the launch of the 'JPYC EX Integration API' for wallet operators and service providers utilizing the Japanese yen-pegged stablecoin 'JPYC'.

This API enables a seamless transition for users from a service provider's wallet application or service interface to the issuance and redemption process screens on 'JPYC EX', operated by the Company. For the development and implementation of this API, Simplex Co., Ltd. (Headquarters: Minato-ku, Tokyo; Representative Director: Hideki Kaneko), which also developed JPYC EX, served as the technical development partner.

As a result, users can now complete JPYC issuance and redemption procedures seamlessly without leaving their everyday wallet or service platform.

Background of the Launch

The Japanese yen-pegged stablecoin JPYC is expected to be used across various use cases, including payments, remittances, web3 services, integration with local currencies and loyalty points, and corporate settlements.

However, for stablecoins to be effectively integrated into real-world service experiences, it is crucial that users clearly understand 'how to issue JPYC' and 'how to redeem it back into Japanese yen'.

Previously, users of wallet apps or other services had to navigate away to JPYC EX to complete issuance or redemption procedures, and then return to their original wallet or service platform.

The newly launched 'JPYC EX Integration API' is designed to improve this user experience by enabling smooth transitions from partner services directly to the JPYC EX procedure screens.

This allows wallet operators and service providers to clearly guide users to JPYC EX within their own service flow, making it easier and more intuitive for users to proceed with JPYC issuance and redemption.

Overview of the JPYC EX Integration API

The 'JPYC EX Integration API' is a suite of APIs designed to enable seamless user transitions from wallet apps or service platforms to the Company's screens on JPYC EX.

Key features include:

- Login and account linking with JPYC EX - Seamless navigation to JPYC EX issuance and redemption procedure screens - Assistance with wallet address registration - Status synchronization for post-transaction screen control

By utilizing this API, users can initiate and complete JPYC issuance and redemption procedures from within their familiar wallet or service app, creating a unified and integrated experience.

It should be noted that this API is solely a connectivity tool to streamline user navigation and does not authorize partner services to accept issuance/redeemption applications or determine transaction eligibility or reservation confirmations on behalf of the Company. All procedures including review, additional authentication, final application acceptance, and confirmation will continue to be conducted by the Company as before.

Implementation Example: Integration with HashPort Wallet

As an implementation example, integration with 'HashPort Wallet', a web3 wallet app provided by HashPort Inc., is planned.

By leveraging this API, HashPort Wallet will enable users to smoothly transition from the HashPort Wallet interface to the issuance and redemption procedure screens on JPYC EX.

This allows users to access JPYC EX directly from the wallet app, confirm details, complete authentication and application procedures on JPYC EX, and then proceed to confirm JPYC receipt and initiate transfers within the wallet.

Future Developments

Going forward, JPYC will continue enhancing connectivity from external services to JPYC EX, striving to build a stablecoin utilization ecosystem that is intuitive for users and easy to adopt for businesses.
