Asteria and Howdy Crypto Form Business Alliance on Stablecoins – JPYC Gateway to Standard Support Domestically Developed Hardware Wallet Openloop

Asteria Corporation (Headquarters: Shibuya-ku, Tokyo; Representative Director and President: Yoichiro Hirano; Securities Code: 3853; hereinafter "Asteria") and Howdy Crypto Inc. (Headquarters: Chuo-ku, Tokyo; Representative Director and President: Kazunori Asada; hereinafter "Howdy Crypto") announce a business alliance between Asteria's corporate JPYC deposit/withdrawal management service "JPYC Gateway" and Howdy Crypto's domestically developed hardware wallet*1 "Openloop" (hereinafter "Openloop"). This partnership will provide companies adopting JPYC Gateway with a secure environment for managing private keys*2 and other assets, accelerating the utilization of stablecoins by businesses. Furthermore, Openloop will be provided free of charge to the first 100 companies that pre-introduce JPYC Gateway.

■ Background of the Business Alliance

With the issuance of the Japanese Yen-pegged stablecoin JPYC*3 commencing in October 2025, and projections of its issuance scale reaching approximately 30 trillion yen by 2030, corporate utilization of stablecoins is rapidly expanding.

However, for companies to effectively utilize stablecoins in their operations, secure management of private keys and the signatures generated using them is indispensable. Especially for corporations, the leakage of private keys or unauthorized access directly impacts business risks, thus demanding high-level security. Most hardware wallets currently on the market are manufactured overseas, creating a demand for a reliable device that is domestically developed, supported in Japan, and can flexibly adapt to the evolving Japanese market for Japanese Yen stablecoin management.

Therefore, Asteria, which provides the corporate JPYC deposit/withdrawal management service "JPYC Gateway," and Howdy Crypto, which develops the highly reliable hybrid-designed*4 domestically developed hardware wallet "Openloop," have formed a business alliance to build an environment where companies can utilize JPYC with peace of mind and security.

■ Overview of the Business Alliance

This business alliance will undertake the following initiatives:

• Integrate hardware wallets for private key management with JPYC Gateway.
  When sending funds, transactions are confirmed on the device's touchscreen, and user approval is performed via cryptographic signatures, realizing a secure mechanism where transfers cannot be executed without physical approval from the device.

• As a launch campaign for JPYC Gateway, Openloop will be provided free of charge to the first 100 companies on a first-come, first-served basis.
  This supports companies in quickly establishing a secure wallet environment.

• Jointly develop and provide best practices for corporate stablecoin utilization.

■ About "JPYC Gateway"

"JPYC Gateway" is Asteria's corporate JPYC deposit/withdrawal management service. The transaction fee is 8 yen per transaction, which is significantly cheaper than typical bank fees, and it can be integrated with existing ERP and accounting systems via ASTERIA Warp using no-code.
