Cold Wallet Hardware Devices

Cold wallet hardware devices are encrypted “self-custody” electronic wallets that are not connected to the internet (and are thus safe from hackers). These devices hold your private keys and are designed to be very difficult to hack. Some look like a USB flash drive or microcard; others have an LED display. Many require a PIN and “seed phrase” to regenerate private keys.
