A cold wallet is an offline cryptocurrency wallet that stores the private keys to your cryptocurrency funds in a more secure manner, away from the internet. Even if you make transactions from a cold wallet, the wallet confirms the transactions in an offline environment. This process helps keep your private keys away from the internet at all times.
