Your private key is split into 3 components which are stored separately to ensure security. Your key components never leave your devices during transaction signing.
These are the features that make GP7 so great. For differences between TSS and other technologies see the comparison table.
GP7 doesn’t use a master key, but generates separate key components instead. All components are generated in a decentralized manner so that the components cannot be merged in one place, allowing an attacker to get hold of them and sign transactions.
We have created a groundbreaking desktop key manager. In case you lose your key component it will help you restore your wallet app, funds, and the lost component.
Store your key components on different devices for extra security
Recover your wallet with all your funds via the desktop app
Lock your device in case it is lost or stolen to prevent access to your money
You can set a limit for transactions. You will need to confirm your transaction in case its amount exceeds the limit.
