Hamirach Signer

Hamirach Signer is a business-to-business authorization companion app used by employees and administrators of companies operating on the Hamirach corporate treasury platform.

The app does not provide cryptocurrency exchange, trading, brokerage, wallet, or storage services to end users. It is restricted to authorized corporate employees who use it to approve internal transfer requests issued by their company's web-based administration panel.

Key capabilities:
• Receive internal authorization requests created by company administrators
• Review transaction details and destination
• Approve or reject each request using biometric authentication and a personal PIN
• Multi-Party Computation (MPC) technology ensures no single device ever holds a complete signing key

The app is operated under ISO 27001, SOC 2, and PCI DSS compliance controls. Access requires a one-time pairing code issued by the company's administration panel, and use is limited to authorized internal operators.
