TREZOR One is a hardware portfolio launched in August 2014 and is a pioneer in the hardware wallet market: it is the first to offer ultra-secure cold storage while allowing transactions to be made easily in cryptocurrencies. The size of a USB stick, it connects to a computer via a cable. Bitcoin, Ethereum, and all other altcoin private keys are stored exclusively offline.
its use remains safe even on a computer infected with a virus or malware, which no online wallet or office wallet can guarantee.
TREZOR works on the same principle as the most popular hardware wallets on the market. The device connects via USB cable to a computer and allows the user to make secure transactions without having to trust any third partyTREZOR supports more than 500 cryptocurrencies. The choice is less important than with the Ledger Nano S, but it remains extremely interesting.
