Overview

With self custody on Fortary, external keys that are imported into the platform are done through the Fortary mobile app. The keys are sharded between 2 MPC TEE nodes managed by Fortary and within the dedicated mobile device that you imported the keys into.  Keys are a very vulnerable piece of holding crypto assets. Exposed keys can mean permanent loss of assets. This procedure may take time to set up, but it provides layers of security to keep your keys secure while your organization operates efficiently.  Here is additional info on imported keys and mobile device considerations.
