Trezor is a hardware wallet for cryptocurrencies like Bitcoin. It is designed to provide secure cold storage, protecting cryptocurrencies from various types of threats, including malware and physical compromise.
The key idea behind hardware wallets like Trezor is to isolate the private keys from the internet and the rest of the world. This way, even if your computer is compromised, your private keys cannot be stolen. To perform a transaction, the device signs the transaction inside its secure environment and sends the signed transaction back to your computer to be broadcast.
Trezor supports a variety of cryptocurrencies, including Bitcoin, Litecoin, Ethereum, and many others. It also features a user-friendly interface and the ability to backup your wallet in case the device is lost or stolen.
