Cold wallet
A wallet setup that keeps signing keys offline during ordinary storage.
In more detail
Cold storage puts distance between signing keys and an internet-connected device. Transactions can still be prepared elsewhere and passed to the offline signer. It mainly reduces certain remote attacks; backup loss, a mistaken destination and authorizing a harmful transaction remain separate problems to handle.
How you might use it
You prepare the payment on a connected computer, then pass it to an offline signer that keeps the keys off that computer.
