Trezor
Trezor is a portable hardware wallet, providing two variants: the Model T (enhanced version) and Model One. Their hardware wallets utilize open-source designs, allowing public auditing and enhancement of the security level. The hardware wallets require a user-set PIN that can be up to 50 digits long. The wallet can interface with the internet via the Trezor Suite application or well-known third-party wallets such as MetaMask.
