Hardware Wallets: A hardware wallet is a special type of bitcoin wallet which stores the user’s private keys in a secure hardware device.
They have major advantages over standard software wallets:
private keys are often stored in a protected area of a microcontroller, and cannot be transferred out of the device in plaintext
immune to computer viruses that steal from software wallets
can be used securely and interactively, private keys never need to touch potentially-vulnerable software
much of the time, the software is open source, allowing a user to validate the entire operation of the device

The Trezor One by SatoshiLabs paved the way for the ever-growing hardware wallet industry. Launched in 2014, the original vaulting solution for cryptocurrency continues to be widely used today – in spite of the appearance of more modern alternatives.
For users that like to balance security with usability, the Trezor One’s small form factor and compatibility with a handful of desktop, browser, and mobile wallets make it a reliable everyday crypto wallet.
The web interface allows users to manage, send, and receive thousands of coins and tokens or to sign and verify messages. It doesn’t yet support multisig or native SegWit for Bitcoin transactions, but the Trezor One can be used with Electrum to get around these limitations.
When connecting the wallet to another device, users must enter their PIN to unlock it. The numbers are mapped to a grid on the Trezor, but masked on the other device’s screen. The device must be used in conjunction with the wallet for the user to input their PIN. This ensures that the computer, even if compromised, can’t gather any information from the wallet.
Nonetheless, because the Trezor One is more dependent on a secondary device for operations, it generates a 24-word seed phrase for greater security. Still, seeds of different lengths can be recovered on the device.
Another nice addition is the Trezor One’s usability as a password manager.
The TREZOR Model-T is a second generation Bitcoin/Altcoin hardware wallet manufactured by SatoshiLabs. The TREZOR line debuted in 2014 with the TREZOR One (T-One) and has remained one of the most popular cryptocurrency cold storage solutions to date.
The footprint of the Model-T is similar to the T-One, with the biggest differentiator being the color touchscreen and lack of physical buttons. The Model-T’s firmware (dubbed TREZOR Core) was written from scratch to further optimize security. As with the T-One, this hardware wallet is designed to be used safely even on malware infected devices (although this is not recommended).
KeepKey is a hardware wallet that secures bitcoin, bitcoin cash, ethereum, litecoin, dogecoin, dash and multiple erc-20 tokens. KeepKey works with the wallet software on your computer by taking over the management of private key generation, private key storage, and transaction signing.
