Hamirach Signer

Hamirach Signer is a secure mobile application for approving and signing cryptocurrency transactions using Multi-Party Computation (MPC) technology. Built for teams managing digital assets, Hamirach Signer provides enterprise-grade transaction approval workflows with multi-layer security verification. KEY FEATURES — MPC Transaction Signing Approve transactions with threshold signatures. Multiple signers must approve before any transaction executes, eliminating single points of failure. — Multi-Layer Security Configure up to 3 verification layers per transaction: biometric authentication (fingerprint or face), PIN code, and TOTP (Google Authenticator compatible). — Real-Time Approval Queue View pending transactions with urgency indicators. Filter by status, amount or network, and retry requests that were temporarily blocked. — Business Context On Every Request Amount, destination, network and fees are shown before you approve, so the decision is made with the full picture. — Multi-Network Support Sign transactions on Polygon, Ethereum, Base and more. Monitor vault balances across all supported networks. — Signing Policies Set custom policies per network: minimum signers required, transaction limits and time-locked approvals. — Key Ceremony Securely generate and distribute MPC key shares among authorized signers with a guided setup flow. — QR Device Pairing Pair your device with the Hamirach admin panel using encrypted QR codes. SECURITY - No private keys stored on the device - Biometric, PIN and TOTP verification layers - AES-256 encrypted local storage - Certificate-pinned API communication - ISO 27001 compliant infrastructure Hamirach Signer works with the Hamirach platform (hamirach.com) — white-label fintech infrastructure for crypto and fiat services. It is intended for authorized operators of companies using that platform, not for the general public.
