Trezor was first presented in 2014 by a company settled in the Czech Republic, known as Satoshi Labs. It’s the first cryptocurrency hardware wallet, i.e. a digital wallet that stores your private keys in a secure hardware device.
Trezor is essentially a miniature device, with a size of a keychain or thumb, and you can easily connect it to your computer with a USB cable. The fact that it stores your crypto assets offline in cold storage makes Trezor Wallet more secure than other wallets, even if you connect the device to a malware-infected computer.
