Trezor

Trezor is a hardware BTC wallet that works as a USB dongle, allowing clients to securely get access to cryptocurrencies even if a user's device is not safe. It was created in the late summer in 2014 by Satoshilab. Nowadays, it is one of the leaders in the market among hardware wallets.

Design

Trezor designers chose a minimalistic style for this cold wallet. The gadget is small, it has two buttons and the display. Apart from this, Trezor is tamper-proof, water-resistant, and very durable. It requires a USB cable to connect to a computer or mobile devices.

Compatibility

The Trezor hardware wallet is compatible with Windows, Mac OS, and Linux. It can also work on one of the mobile operating systems – Android. The browsers that support this wallet are Google Chrome and Firefox. A BTC owner can use other browsers as well, but they can’t give 100% of the functionality.

Cooperation

The wallet cooperates with many third parties that work in the sphere of cryptocurrencies:

• Wallets: ArcBit, Blockonomics, Mycelium, Sentinel, Electrum, Etherwall, etc.;
• Services: Bitex, Bitstamp, Bitwala, Coinmap, Coinpayments, Osclass, etc.

However, some applications cannot support all Trezor features.

Privacy

The wallet doesn’t require a lot of personal information. Basically, a user has to specify their contact information, such as email.

Security

A cold wallet is safer than any hot wallet, as the chance someone hacks it is greatly reduced. However, it isn’t enough to provide a really good level of protection. For this reason, Trezor has some other security features:

• Recovery seed. It is a mnemonic code that can include 12, 18 or 24 words. The code aims to protect the wallet and recover it if a user loses access to it. This group of words is randomly generated by users when they start working with Trezor. If a device is lost or stolen, it is possible to revive private keys, transaction history and even balance by entering the wallet from another gadget with the help of the seed.
• PIN code. The PIN number is created by a user. Moreover, there is a special method of entering the PIN code that increases the wallet's security level.
• Encryption passphrase. This measure is necessary to protect users in case of a hacking attack. A passphrase is similar to a password, but it is quite longer for additional security.

Even though the Trezor wallet is protected, the company advises not to forget about personal security measures. The good thing is that Trezor is an open-source, which means that users can help improve services and get rid of possible flaws.
