Asteria Corporation (Headquarters: Shibuya-ku, Tokyo; President: Yoichiro Hirano; Securities Code: 3853; hereinafter 'Asteria') and Haudi Crypto Inc. (Headquarters: Chuo-ku, Tokyo; President: Kazunori Asada; hereinafter 'Haudi Crypto') announce a business alliance between Asteria's corporate JPYC deposit/withdrawal management service 'JPYC Gateway' and the domestically developed hardware wallet*1 'Openloop' (hereinafter 'Openloop') developed by Haudi Crypto. This partnership provides a secure management environment for private keys*2 for companies adopting JPYC Gateway, accelerating the use of stablecoins in business. Additionally, Openloop will be provided free of charge to the first 100 companies to adopt JPYC Gateway.
■ Background of the Business Alliance
With the issuance of the Japanese Yen-pegged stablecoin JPYC*3 scheduled to begin in October 2025 and projected to reach a scale of approximately 30 trillion yen by 2030, the use of stablecoins by enterprises is rapidly expanding.
However, for companies to utilize stablecoins in their operations, secure management of private keys and signatures is essential. Especially for enterprises, leakage of private keys or unauthorized access directly impacts business risk, requiring high-level security. Most hardware wallets currently on the market are manufactured overseas; there was a demand for a highly reliable device developed and supported domestically that can flexibly adapt to the evolution of the Japanese market for managing Japanese Yen stablecoins.
Therefore, Asteria, which provides the 'JPYC Gateway' service, and Haudi Crypto, which develops the 'Openloop' hardware wallet with a highly reliable hybrid design*4, have formed this alliance to build an environment where companies can utilize JPYC safely and securely.
■ Overview of the Business Alliance
This alliance includes the following initiatives:
- Integration of hardware wallets for private key management in JPYC Gateway. When sending funds, transaction details are confirmed on the device's touchscreen, and user approval is performed via cryptographic signature, ensuring that no transfer can 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, supporting them in building a secure wallet environment immediately.
- Joint development and provision of best practices for corporate stablecoin utilization.
■ About 'JPYC Gateway'
'JPYC Gateway' is a corporate JPYC deposit/withdrawal management service provided by Asteria. Transaction fees are 8 yen per transaction, significantly lower than general bank fees, and it can be linked with existing ERP and accounting systems via ASTERIA Warp without coding.
■ About 'Openloop' Hardware Wallet
'Openloop' is a domestically developed hardware wallet (crypto signer) planned, designed, and developed from scratch by Haudi Crypto. It features a built-in EAL6+ certified secure element to strictly protect the seed (the master key for private keys) within the device. Furthermore, its unique 'DualSecure' technology, which combines keys from two independent chips to double-encrypt the seed, maintains safety even if one chip is attacked.
It is designed for ease of use by individual and corporate users, featuring a touchscreen, battery operation, and audio feedback. It supports three connection methods: Air Gap (QR code), USB, and Bluetooth, allowing for flexible operation according to security policies.
