Keeping cryptoasset signing keys offline to reduce exposure to internet-connected attacks.
How it works
Cold storage keeps the private keys needed to authorize cryptoasset transfers away from internet-connected systems. Implementations include dedicated hardware and carefully controlled offline signing processes.
Example
A hardware wallet can sign a transaction without exposing its private key to the connected computer, provided the device and recovery process remain secure.
Limitations
Offline storage reduces online attack exposure but creates loss, damage, inheritance, backup, and physical-security risks. It does not protect against sending assets to the wrong address.
