About this app

Protect your reputation and pave the way for the mass adoption of digital assets with Impenetrable Custody—the only technology that enables institutions to support digital assets that are 100% theft-proof.

The app is available exclusively for GK8 customers—join us to get started!


The GK8 mobile app allows you to:
- Create, confirm and authorize transactions
- Execute predefined transactions from the Proxy Vault without accessing the Impenetrable Vault

GK8’s mobile app almost exactly mirrors the functionality available in the desktop version. This means mobile users can initiate transactions from the mobile app rather than execute transactions created elsewhere. This ensures seamless, real-time management of digital assets, whether you're in the office or on the go.

GK8’s uMPC enables an unlimited number of co-signers, delivering unparalleled security and significantly increased speed. While current MPC solutions, with up to three shards, often cap at 6-8 signatures per second, GK8’s uMPC, tested with 30 shards, achieved up to 7,500 signatures per second.

With uMPC, financial institutions can leverage the most advanced MPC capabilities to protect their digital assets while meeting regulatory requirements and enhancing operational efficiency.
