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.
KeepKey is a cold-storage wallet that has no operating system. PIN and passphrase protection guard against unauthorized use. You get customizable transaction speeds and limitless wallet addresses on one device.
KeepKey is owned by ShapeShift, a digital assets platform that enables customers to buy, sell, trade, track, send, receive, and interact with their digital assets.
Keystone offers staking a high-end cold storage wallet for advanced users (Cobo Vault), and custodial services for institutional investors, with support for more than 30 coins and 700 tokens.
Ledger Nano X can be optionally and temporarily connected via cable to a Mac or Windows device so you can buy, sell, exchange, stake, lend, and otherwise manage 1,500+ tokens. The optional Live Ledger mobile app manages the wallet via Bluetooth; wireless connectivity is otherwise blocked.
NGRAVE is a cold wallet device that is completely “air-gapped” and does not rely on any kind of network connection capability (such as WiFi/Bluetooth/NFC). It prevents online attacks by using a one-way QR code to relay information.
