Full origin of cold wallet →Frequently asked questions
What is the difference between a cold wallet and a hot wallet?
A hot wallet is connected to the internet, which makes it convenient for frequent transactions and reachable by online attackers. A cold wallet keeps the keys offline, which makes theft over the internet far harder but every transaction more of a chore.
Is a cold wallet the same as a hardware wallet?
A hardware wallet, a small dedicated device that keeps keys offline, is the usual form of cold wallet, but not the only one. Keys written on paper or stamped into metal and stored away are also cold storage.
What happens if a cold wallet is lost or broken?
The device itself is replaceable; what matters is the recovery phrase generated when it was set up. With that phrase the same keys can be restored on another device. Without it, and without any other backup, the funds cannot be reached by anyone.
