In this growing era of crypto investing, exchange hacks, phishing attacks, and millions of funds in software wallets are at risk. And the one question that matters the most here is Where are the private keys of the wallet account? 

Should there be any connection to the internet, your funds are exposed to a risk that no password, two-factor authentication, or antivirus can adequately address.

Trezor Wallet offers an alternative. With Trezor, your private keys will not be stored anywhere online or accessible to your personal computer. Instead, it utilizes an offline hardware component that will hold your private keys in complete secrecy.

In this guide, we will explore all there is to know about the Trezor wallet. We will look into its features, explain how it works, and show you how you can secure your investment with it.

By Trezor Wallet, we mean the whole range of hardware wallets designed by SatoshiLabs, an international cybersecurity firm established in Prague, Czech Republic. The first-ever Trezor model was released back in 2014 by SatoshiLabs, and it became the world's very first hardware wallet for Bitcoin.

So how does a hardware wallet like Trezor Wallet operate? In essence, your private key, the credential that proves your ownership of your cryptocurrency, is generated within your hardware wallet and remains there forever. As soon as you authorize a transaction on your computer, it is then signed directly on your device. What your computer receives is just a signed transaction, but not the private key used to sign it.

Today, SatoshiLabs designs two main types of hardware wallets. The Trezor Model One is the original hardware wallet with two buttons for operating it and no screen. It is relatively cheap yet quite reliable. Another device called the Trezor Model T comes with a color display screen and supports more coins. Additionally, it features a new type of wallet protection – Shamir Backup.

To learn the reasons why the Trezor wallet is a safe space for crypto assets, take a look at the wallet briefing. This will explain why this wallet is different from the software wallets or exchange accounts.

Isolation of Private Key 

• On the initial set-up of a Trezor wallet, the Trezor hardware generates the random private key using a hardware random number generator on board the hardware. 

• It is important to note that the key is never communicated to the computer; neither does it appear on-screen in a readable digital format, nor is it saved elsewhere apart from being held within the secure hardware chip. 

• The computer is simply a monitor that allows the user to interact with the wallet but does not contain any sensitive data.

The Recovery Seed

• As part of the wallet setup process, the Trezor Wallet creates a backup called the recovery seed consisting of 12 or 24 words based on the BIP39 industry standard. 

• This recovery seed is shown on the hardware device's screen word by word. 

• The user needs to write down the seed on a physical piece of paper and keep it safely offline.

PIN Protection

• All Trezor Wallets have a unique PIN code that is entered directly into or via the hardware device itself. 

• For the Model One, the PIN code is entered by inputting random numbers from a grid visible only on the device’s mini-screen; thus, your computer does not know which digits you are entering even if it records your keystrokes due to malware. 

• In the case of the Model T, PIN is typed directly onto the device’s touchscreen, thereby not even using the computer. 

• Once the maximum number of invalid PIN attempts is reached, the device is wiped.

Physical Transaction Verification

• A transaction cannot be verified by any Trezor Wallet without direct physical interaction with the device.

• When you send crypto from the Trezor Suite interface, the transaction details such as recipient address, transaction amount, and network fees are shown on the hardware wallet’s display for you to verify before confirming the transaction. 

• By confirming a transaction via a physical button press or touchscreen, you ensure that even if your computer is fully taken over by malicious software, no stealthy transaction can be executed.

Trezor Wallet offers support for a vast number of cryptocurrencies and their constant growth. All variations of Bitcoin, Ethereum, and all the ERC-20 tokens are covered, as well as Litecoin, Bitcoin Cash, Cardano, Solana, Ripple (XRP), Stellar, Dogecoin, Tezos, Polkadot, and literally hundreds of other types of digital assets. Model T offers a wider selection of assets than Model One thanks to its superior hardware specifications.

Apart from the fundamental hardware-based isolation technology, the Trezor Wallet comes with several other innovative tools for those who want additional security layers.

Passphrase

 You may set up an additional passphrase in order to create unique, hidden wallet accounts based on your recovery seed. Unlike the seed itself, this additional passphrase is never recorded in the device and needs to be manually typed every time you use the hardware wallet. This tool adds yet another layer of security to your account because even if someone steals your hardware device and knows your PIN code, they won’t be able to access your hidden wallet without the additional passphrase.

Shamir Backup (Model T)

The Trezor Model T incorporates Shamir’s Secret Sharing technique that breaks down your secret recovery seed into multiple parts called shares (e.g., 3-of-5). Your wallet cannot be recovered until the minimum share limit required to unlock it has been met.

Multiple Accounts Per Coin Type. 

Trezor Wallet enables you to manage multiple accounts for each coin type independently within one device.

Trezor Wallet may well be regarded as a revolutionary breakthrough in terms of cryptocurrency security. This gadget has been in use for a decade, gaining the confidence of millions of customers due to one simple yet profound feature: your keys always remain offline, safely in your possession and inaccessible to any hacker in the world. The company provides models from the basic model One to more sophisticated Model T with Shamir Backup, which is an equally secure product for everyone, regardless of individual security requirements and budget.

Any individual who possesses cryptocurrencies he cannot afford to lose should be aware that Trezor Wallet is mandatory.
