What Are Cold Wallets?
Cold wallets are also called hardware wallets. Cold wallets are hardware devices resembling USB storage devices with connectivity features like USB, WIFI and Bluetooth. Cold wallets secure crypto assets held in a blockchain account by storing the wallet’s private keys offline, unlike hot wallets which are always connected to the internet.
This makes cold wallets more inconvenient to use, as signing transaction requests involves more steps. However, their reduced convenience is a key part of its rigid security structure. Some popular cold wallets include Trezor, Ledger, SafePal, and Tangem Wallet. The security level of cold wallets is usually rated according to the EAL metrics.
