Trezor ONE introduction

Trezor One (or previously simply Trezor) is the first model of Trezor device line and simultaneously the first hardware wallet in the world that was released on July 29, 2014. It offers unmatched security for cryptocurrencies, password management, second-factor authentication, while maintaining an absolute ease of use, whether you are a security expert or a brand new user.



The TREZOR One is a battle tested hardware wallet that supports a wide variety of cryptocurrencies at an affordable price. The company behind it (Satoshi Labs) is considered a pioneer in the Bitcoin industry. Additional security measures such as PIN codes and passphrases make this hardware wallet as close to “hack proof” as you can get.

Full control in your hands

Trezor is a small single-purpose computer. It is designed to protect your private keys from possible online and offline risks. To do this, Trezor keeps the private keys away from the Internet and confirms the transactions in-device. That way, you can always check the screen for the right address, amount and transaction fee before sending your bitcoins.


In layman’s terms, you can connect Trezor to an infected computer and still be able to have 100% control over the funds in your device.

One of the Best Wallets Around

Trezor One is an advanced and reliable hardware wallet, designed to keep your Cryptocurrencies safe & secure. It supports over 1800 different cryptocurrencies, including Bitcoin, Litecoin and Ethereum. The Trezor wallet has several cryptographic encryptions to keep your coins safe from malware, viruses and hackers.


The most important function of this amazing hardware wallet is to store, sent and receive your cryptocurrencies in a safe & reliable way. However, the device can also be used for:


  • 2 factor authentication for several services, like Dropbox en Gmail.
  • Very secure password-manager
  • Full support for ERC-20 tokens.

Recovery seed. Offline.

Your entire wallet is always accessible via your personal 12 to 24 words long recovery seed. you can do it anytime you want .


Unique for you.

When you first set up your Trezor, it will generate the seed for you. When you need to restore access to your wallet, use this offline backup.



The recovery seed follows a standard created by us at SatoshiLabs, but it is widely used, compatible with many wallet apps.

Top perks of Trezor ONE 

Offline storage

your coins are kept off the internet so hackers cannot get to them. Cold storage is safer than hot storage, as access to your coins is impossible via the internet. your crypto is as safe as it can be when entrusted to the care of a Trezor device. With the Trezor One, your coins will be much safer than they would be with your average software wallet.



Trezor One uses limited USB access to ensure safety with other devices. When the Trezor connects to another device, it only gives permission to send and receive cryptocurrency transactions. This means that it can connect to malware-infected devices without risking your coins. This wallet provides great security for your coins, and ensures that even if the device is lost, your coins won’t be.



Recovery seed for lost or destroyed wallets

One of the fail safes Trezor offers when you use its hardware wallets is a method of recovery for lost or destroyed wallets. Trezor provides you with a recovery seed when setting up your device. If you lose your device, your recovery seed can be used to get your coins back.



Exchange currencies in the wallet

it allows users to exchange their coins for others, right within the Trezor app. This wallet does not force users to choose between flexibility and security. Trezor allows users to keep their coins in cold storage, while diversifying their portfolios with Trezor’s exchange. New investors can make trades without having to give their information to an exchange or transfer their funds from wallet to wallet.

Advanced features for expert users.

Compatible with many applications, ready for power users.

Manage your entire digital identity.

Coins, keys or passwords. All in one device, owned and controlled by you.

Is Trezor One Safe?

Your private keys are stored and isolated inside the device, keeping them offline. A PIN code is required to access the hardware wallet, and all transactions must be confirmed by pressing the physical buttons on the wallet which are connected to a device via USB cable.


An extra security feature is that you can create a separate account protected by a passphrase. You can store whatever assets you wish here, so if your PIN is compromised, whatever is stored in this separate account cannot be accessed. This makes it harder for your assets to be compromised if lost or stolen.


Finally, this product uses a 24-word recovery seed phrase. There is also the option to use a 12-word recovery phrase.

In addition, Trezor allows compatibility with Universal 2nd Factor (U2F).

Which cryptocurrencies does Trezor One support?

The product supports over 1,000 different types of cryptocurrencies, including Bitcoin, Ethereum, Tether, and more. However, the device’s offering is missing a few essential coins. If you are looking to store Ripple, Cardano, or Monero, you will need to invest in another hardware wallet.

What is inside the box ?

Thw package is protected by two silver seals on both sides and is wrapped in a thin plastic foil. The package is carefully sealed with a strong glue, which makes it impossible to open the package without tearing it apart. It contains the following:

  • Trezor One device
  • USB cable (type B)
  • Getting started card (package)
  • Recovery seed card (24 words) 2x
  • Sticker 4x


TREZOR provides top-notch security for bitcoin (BTC), protecting against both physical and virtual theft.

TREZOR is an HD wallet where you control the private keys, so an entire wallet can be backed up with the 24 words generated on setup. The original 24-word seed is generated using RNG from the device and the computer. The seed is generated offline and displayed on the TREZOR’s screen, which ensures that the seed is never on an internet-connected device.


A PIN code is required on setup, and required for spending.

After each incorrect guess the wait between guesses is raised by a power of two. Making 30 guesses would take 17 years.


You can add a passphrase to the 24-word seed as an extra security feature, which acts as a 25th word. You must remember the passphrase because the seed without the passphrase is not enough to recover the wallet. A passphrase offers more security, but if forgotten the wallet cannot be recovered.


You can recover the entire wallet with the 24-word seed and passphrase if used, in the event that your TREZOR is lost or damaged. Recovery can be done with another TREZOR or with other wallets, like Electrum or Mycelium.

TREZOR’s screen allows you to confirm that you’re sending to the intended recipient, but this does not prevent against phishing attacks.

Best Features of Trezor ONE

The best features of the Trezor One cryptocurrency hardware wallet are that it is extremely secure and Trezor provides detailed step-by-step support for setup, purchase, and exchange of assets.

Many Trezor One reviews also highlight the affordability of the wallet. At around half the cost of the Ledger Nano X, and even cheaper than the Nano S, the Trezor One offers the same level of security. It’s also significantly cheaper than Trezor’s other wallet — the Trezor Model T.



this product also allows users to purchase crypto directly through the Trezor Wallet app using fiat. These purchased assets can be traded on there too. With this setup, you  are able to safely store your crypto assets right away.



It’s also worth pointing out SatoshiLabs, the inventors of the Trezor wallet, are constantly innovating and developing different cryptocurrency-based projects. Over the years SatoshiLabs have helped a variety of different crypto companies shore up their security including some open-source projects. They are a huge boon for the crypto industry overall.

Trusted by Over 300,000 Customers Worldwide.

I think it’s only a matter of time before most companies
(if not all) start working on TREZOR compatibility. This is a very solid device
in my opinion, and considering they are working on it continually, it can only
get better. I hope they can stay ahead of the hackers…

7 Reasons why Trezor’s Wallets Are Fantastic

1. Trezors Are All Cold Wallets

trezor one

Most crypto wallets you’ll find in the market are software-based. It removes the need for service providers to manufacture and hold inventory. That means less capital expenditure and risk on their part.


For users, hardware wallets offer a degree of security that isn’t in the same league as software wallets. Unless you somehow hook a hardware wallet up to a connected source, it’s not going to get hacked.

2. Trezor Wallets Are Ultra-Portable

trezor one_size

Trezor devices are tiny and will easily fit into the palm of your hand. The lightweight construction doesn’t seem exceptionally durable, but it’ll ensure portability no matter how you carry it.

The smaller model is a mere 60mm x 30mm x 6mm (2.4in x 1.2in x 0.2in) and weighs a mere 12 g (0.42 oz). The Model T is larger at 64 mm x 39 mm x 10 mm (2.52 in x 1.54 in x 0.39 in) and ups the weight to 22 g (0.77 oz).

3. Security On Any Trezor Is Airtight

Aside from them being hardware wallets, Trezor puts a tremendous focus on the security of their wallet. It starts with the Trezor Core, a custom-designed operating system (OS) that runs on their devices.


That’s only the beginning, though. Security on Trezors is so comprehensive that the following offers just a taste of what they do to help protect your crypto;

1. Trezor Trusted Display

The Trezor Trusted Display is hard-baked to show only the exact details of ongoing transactions. If your PC or phone is somehow compromised, you’ll be able to tell by the mismatching information. That gives you enough time to cancel any transactions.



2. On-device security


On-device security is an essential element for protecting your private key as well. No matter what you’re doing, confirmation via a PIN on your Trezor will be mandatory. Unless you lose both the Trezor and your PIN, that’s not likely going to happen.



3.Solid cryptography

Trezors support various high cryptography standards that help increase the security of your transactions. For example, their BIP-39 passphrase adds extra length to seeds, further increasing resilience.




It’s configurable enough to add high complexity, so even some missing words aren’t enough to compromise security. At the same time, you can split and the seeds on multiple devices to make things even more difficult to compromise.



4.Trezors protect themselves

One common way that hackers attempt security breaches is by infiltrating devices. For example, they might access a device and overwrite or modify specific code such as the OS or firmware.


Trezors safeguard against this with firmware signature verification. Only signed firmware will run, and tampering will display warning messages. At the same time, nobody can replace Trezor bootloaders as they’re write-only.

4. Increase Anonymity By Routing Through Tor


Trezor offers communications that can be routed via the Tor network, potentially increasing the anonymity of your transactions. This capability requires special server configurations on their infrastructure, but to us, it just takes the toggle of a switch in the Trezor Suite.


Aside from enabling Tor communication, you can also set a unique IP address and port number. In addition, you can also opt to open the .onion version of any Trezor links.

5. Trezors Are Easy To Use With A Smooth Onboarding Process

trezor one _start

when you receive the package and  in original sealed packaging. Inside, there is the device, some accessories, and tiny documentation slips. You can junk the documentation and simply head to


From there, download the Trezor Suite and install it. The suite will guide you through the entire setup process. It’s fast and painless, even for the greenest of newbies. The process will take you just a few minutes.

6. Over 1,800 Crypto Types Supported

Trezor supports over 1,800 types of crypto, from the mainstream to the obscure. if you want to check if your crypto of choice is supported, simply head to the list of crypto supported on the Trezor website.


Do note, though, that this number refers to the cryptos supported. At any time, your Trezor only allows you to handle ten crypto accounts of your choice. you can use it for Bitcoin, ETH, and Dogecoin. It’s a limitation enforced by Trezor to keep their server loads more manageable.


Aside from the main crypto list, you can also handle several testnet coins on your Trezor. These aren’t “real” crypto but are useful for testing.

7. Trezor Displays Are Surprisingly Readable

trezor one_display

When you first glance at the Trezor wallets, you might be a little concerned about the seemingly tiny displays. The Trezor One has an OLED display of only 128×64 pixels but its well made .


When you connect it , you will be pretty impressed with the quality and legibility of the text. The Trezor One offers slightly fuzzier text, but it is undoubtedly readable. you might also be impressed with the inclusion of touchscreen technology.

Conclusion – Is the TREZOR One worth it?

the experience with it is extremely pleasant. The setup is easy, the device is intuitive and the security measures seem pretty robust.



The Model One has an obsolete port, the Trezor Suite doesn’t display NFTs, and it doesn’t support XRP, Cardano, Binance Smart Chain, and a slew of other popular crypto networks. It’s not compatible with iOS nor Chrome OS. 


The Ledger Nano series may have an edge over the Trezor line due to its stellar Ledger Live app, but the 2020 hack doesn’t sit well with many crypto investors. the Trezor Model One is ideal for investors who prefer to trade blue-chip cryptocurrencies (e.g., Ethereum and Bitcoin) — established digital assets that will likely stand the test of time.

Frequently Asked Questions (FAQs)

Here you can find almost all FAQs around web about this product collected by Walletbaz team. also you can ask your questions, then we will answer your questions and add them into this page FAQs section


I lost my hardware wallet. Now what ?

That is not a problem. You can restore your accounts to a new hardware wallet using the recovery key you wrote down when you set it up.

Is it possible to restore all cryptocurrencies with a hardware wallet backup ?

Most wallets support more than just one cryptocurrency, but only generate one backup. Nevertheless, this one backup is sufficient to restore all cryptocurrencies as all private keys of the different wallets result from the seed that is backed up as a backup during setup.

How does a hardware wallet work ?

Hardware Wallets such as the Ledger Nano X, TREZOR Model T, BitBox02 or KeepKey all work according to the same principle. They are a special form of a so-called wallet, which is used to manage cryptocurrencies. A hardware wallet is a physical device that securely and inisolationly generates the private keys to the cryptocurrencies. Due to the extra hardware, they have some advantages over software wallets:

1- Private keys are often stored in a protected area of a microcontroller and cannot be transferred out of the device in clear text.

2- Hardware wallets are immune to computer viruses that steal from software wallets.

3- They can be used securely and interactively, private keys never need to come into contact with potentially vulnerable software.

4- The software is in most cases open source, so that the user or professionals can validate the entire operation of the device.

However, it is important to understand that hardware wallets are an attractive target for attackers and depend on several assumptions to maintain security. They are not a miracle weapon, and there are several realistic ways to hack a hardware wallet Especially if someone has physical access to the device.

TREZOR Model T or TREZOR One ?

The TREZOR Model T is the successor to the bestseller TREZOR One. Both devices are open source, are subject to the same high security standards and are managed with the TREZOR Wallet. However, the TREZOR Model T offers some improvements compared to its predecessor:

1- LCD Touch color display

2- supports more cryptocurrencies

3- supports Shamir Backup

4- has an SD cards slot

What happens if there are new cryptocurrencies – do I need a new hardware wallet?

A new cryptocurrency is rarely supported directly by a hardware wallet at the beginning. However, most providers such as Ledger or TREZOR are constantly working to support new cryptocurrencies. Therefore, it is often worth waiting until the desired currency is supported by your hardware wallet.

I no longer have access to my TREZOR. How do I reset/wipe my TREZOR ?

If you’ve forgotten your PIN or want to reset your hardware wallet TREZOR Model T or TREZOR One for some other reason, you can do so without any problems.


Note: Before resetting, you should check if you still have the recovery seed if you already have cryptocurrencies stored on your hardware wallet. Otherwise, after the reset, access to the cryptocurrencies is lost!

First, connect to the TREZOR Wallet software.

On the TREZOR Model T, swipe your finger across the screen while simultaneously plugging the cable into the TREZOR Model T. The screen will then display the message that you are in bootloader mode. In the TREZOR Wallet software, you can now press the “Reset Device” button.

With TREZOR One, all you have to do is click away the PIN entry window in the TREZOR wallet. Then go on to the Advanced tab in the menu bar located at the top of the page and look for the “Reset Device” button at the bottom.

Complete the process by confirming the action on your device. The TREZOR is now reset. Now you can set up the hardware wallet again after reconnecting.

Hardware wallets: Where are my cryptocurrencies actually stored ?

Are my cryptocurrencies stored in the hardware wallet, or where exactly are they? This is a very good question because the answer defines what your wallet actually needs to protect.

Cryptocurrencies are so named because they are secured by cryptography. For this you need a set of digital keys, for example your (very secret) private key. With this key you can encrypt and digitally sign things.

Let’s take Bitcoin as an example (other cryptocurrencies work in a similar way). The entire Bitcoin network is kept up to date by a common data structure called the blockchain. It contains records of all transactions ever made and is publicly accessible online, so anyone can read it. When you receive some bitcoins, say 0.1 BTC, you see them in your bitcoin wallet, listed under a bitcoin address.

At the same time, the bitcoins are not actually stored in the wallet, they are just an entry in the public blockchain. What the wallet stores is your secret private key that belongs to that address. Since you control that private key, you can spend those Bitcoins again: that’s how “Bitcoin ownership” is defined. Anyone can see these bitcoins, but only you can spend it, so they are yours. But that also means that *anyone* with the right private key can spend those bitcoins. Therefore, it is very important to keep this key secret.

Is Trezor One a Good Way to Store Bitcoin Cash?

Yes! The Trezor One is a great way to store Bitcoin Cash. Trezor hardware wallets offer top-notch security by storing your private keys on the device and protecting access to your wallet with both PIN code and available passphrase security.

Does Trezor One Have a Touch Screen?

No, the Trezor One does not have a touch screen, it has an OLED display which can show up to six lines of text at a time. The Trezor Model T, Trezor’s newer hardware wallet, offers a touchscreen LCD display, but it costs three times as much as the Trezor One.

What devices and operating systems are supported by Trezor?

Trezor device is compatible both with computer and smartphone. The supported operating systems are Windows 10, macOS 10.11 and higher, Linux and Android OS.

Setting up your new device

Enable communication and connect the device

Begin the setup process by connecting your Trezor device to your computer using a USB cable. Please make sure that the device is properly connected.When connected, open your browser and visit as indicated on your Trezor's screen. Continue by selecting your Trezor model. Download and install Trezor Bridge, an application which facilitates communication between your Trezor device and your computer. After successfully installing, refresh the page and let Trezor Wallet automatically detect your Trezor device. Trezor Bridge is a program designed to run in the background and requires no interaction. In other words, there is no need to open or do anything with Bridge once it is installed.

Install the latest firmware

New Trezor devices are always shipped without a preinstalled firmware to ensure the latest firmware is installed when initializing a new device. Leaving this step to you also enables you to check the legitimacy of the firmware. To install the firmware, simply click on Install firmware.To finish the installation, reconnect your Trezor device when asked.

Create a new wallet

To generate a new wallet, click on create wallet . Your device will generate a new and unique seed which will hold all of your accounts and addresses. Now, although Trezor is ready to be used, we strongly recommend continuing with the onboarding process. To ensure maximum safety of your Trezor, complete the following four steps.

Create a backup

Click on Create a backup in 3 minutes. and prepare to write down your recovery seed on the specially designed cards included in the package. You will be presented with a random set of English words, each displayed on your device's screen. Note that the seed will only be presented to you twice in a row and then never again. It is not possible to get to the seed or have the device display the words ever again. Pay close attention to every word and make sure you write it down correctly and in the right order. Wallet_onboarding_bar Push the right button on your device to see the next word of your recovery seed. Carefully write down the words in the exact order they are presented. Once all of the words are recorded in the recovery card, your Trezor device will display the 24-word recovery seed again so you can verify the correct order and spelling. Warning : Never make a digital copy of your recovery seed and never upload it online! In case the backup fails during the process (e.g., because of a power failure), see Recovery seed backup fail.

Name your device

Giving your device a unique name to make it distinguishable will help you quickly identify your device and make it easier to select it in Trezor Wallet, especially if you use multiple devices. The maximum length of the name is 16 characters. SET UP A PIN A PIN protects your Trezor device against unauthorized physical access. It is recommended to set up PIN protection as soon as you initialize your new device. Having trouble entering a PIN? See our User manual for detailed instructions Enter your PIN by clicking on the obscured numerical pad displayed in the browser. The layout revealing the position of the digits is displayed on your Trezor device. The PIN layout changes at each new prompt. Recommended PIN length is 4-6 digits without repeating digits. The maximum PIN length is 9 digits.

Bookmark the page

Create a bookmark in your browser to enable easy access to the Trezor Wallet interface. By creating a bookmark, you will be able to avoid unnecessary googling and distractions trying to get you to a fraudulent site.

Mastering the basic Trezor Wallet operations

Switching between cryptocurrencies

Trezor supports over 1000 coins and tokens. Select the corresponding cryptocurrency from a drop-down menu in the upper-left part of the Trezor Wallet interface. Note that some coins or tokens are only accessible through a third-party interface. Refer to for more details about supported cryptocurrencies. Wallet_Receive

Receiving payments

To receive a payment, select an account and click on the Receive tab. The receiving address should be verified on your Trezor device by clicking on Show full address. After verification, copy the receiving address and share it to receive your funds. Important : Generate a new address for each receiving transaction to maintain your privacy

Making payments

To make a payment, select an account and go to the Send tab. Now, paste the recipient's address and enter the amount. Optionally, you can change the transaction priority by adjusting the transaction fee Warning : Do not send or receive transactions to addresses generated for a different cryptocurrency, e.g. bitcoin cash to a bitcoin address.

Personalizing the homescreen

Apart from giving your device a nice personal touch, a custom homescreen can serve as another measure against physical attacks. Having a custom homescreen will quickly let you know whether the device is yours or a forged copy. You can personalize your homescreen by selecting your device in our Wallet interface and navigating to the Homescreen tab. You can choose from a wide variety of preloaded images or upload your own.

Staying on top of the security best practices

Choose a unique and strong PIN

Similar to your phone or credit card, the PIN is there to shield your device from unauthorized physical access. It is in your best interest to keep the PIN memorable, but complex enough to make it difficult to guess. We recommend keeping the PIN at least 4-6 digits long. Avoid using a direct sequence (1234) and duplicating digits (1133, 12334, etc.).

Keep your recovery seed safe

You can think of the recovery seed as an ultimate express-pass to your funds. While it is undeniably very useful to you in emergency situations, it can prove to be dangerous if stolen, lost, or destroyed. It is absolutely crucial to keep your seed in a safe and easy-to-remember location. You should always write your recovery seed on a piece of paper or other durable surface with a lasting marker. Do not make any digital copies of your recovery seed and never store it on your computer. Seed_card_front

A few words about passphrase protection

Enabling the passphrase protection in Wallet Advanced settings lets you hide your accounts by "building" an additional layer onto your seed. Unlike a PIN, the passphrase is never stored on the device, and your wallet becomes dependent on it. When you enable this feature, Trezor will ask you to enter the passphrase which will then be combined with your seed (24-word seed used to backup your Trezor) and a new, unique account will be created. Now you might ask "Why bother?". While a PIN provides effective protection for your device, you can think of the passphrase as the ultimate safeguard for your seed. Warning : The passphrase feature is an advanced security measure. It is recommended to use this feature only if you confidently understand its risks and advantages.
