Trezor.io/start – The #1 Hardware Crypto Wallet (Official)
Trezor devices are designed with strict isolation between the secure environment where private keys are stored and the outside world. When a user initiates a transaction, the data is sent to the Trezor, where the signing process happens entirely within the device. This means even if a computer is compromised, the private keys remain securely locked inside the Trezor hardware wallet, inaccessible to any malicious software.
