Cold Wallet Hardware Devices
A cold wallet is used to receive, store and send digital assets.
Cold wallet hardware devices are encrypted “self custody” electronic wallets that are not connected to the Internet (and thus safe from hackers) unless the user chooses to connect to the Internet. These devices hold your private keys and are designed to be very difficult to hack. They must be ‘in hand’ for every transaction.
Some cold wallet hardware devices look like a USB flash drive or a microcard, while others have an LED display. When “air-gapped” they provide no Internet cable or wireless connectivity. Many of these devices require a PIN for access and a “seed phrase” to regenerate private keys.
Cold wallet hardware devices may be compatible with other hardware or online wallets. Popular devices support bitcoin, ether and hundreds of other coins and tokens.
