Hold assets safely, move them on demand.
Hamirach secures digital assets with multi-party computation (MPC): the key is split into shares so no single party ever holds it, and a threshold is required to sign. A device-bound mobile app adds biometric approval for high-value moves.

Frequently asked questions
What is MPC custody?
MPC (multi-party computation) custody splits a private key into shares held by different parties, so no single party holds the full key and transactions require a threshold to sign. It removes the single point of failure of a traditional key.
Which networks are supported?
