Trezor.io/Start | Official Wallet Setup Guide

Welcome to the official, comprehensive setup guide for your new Trezor Hardware Wallet. This guide is designed to take you through the process, from physical unboxing to making your first secure transaction, ensuring maximum security and understanding of the technology.

CRITICAL SECURITY WARNING: Always download the Trezor Suite software *only* from the official Trezor website or verified links. Never enter your Recovery Seed on a computer, phone, or any device connected to the internet. Your seed is only ever entered directly into the Trezor device itself.
STEP 1

Unboxing and Physical Integrity Check

Before connecting your new device, you must rigorously inspect the packaging to ensure it has not been tampered with. Trezor uses several anti-tampering measures, and verifying these is the absolute first step in a secure setup.

1.1. Inspecting the Seal and Box

Carefully examine the holographic sticker or tamper-evident seal on the packaging. If you are using a Trezor Model T, the packaging will feature a specific magnetic seal and a holographic film. If you have a Trezor One, look for the unique, serialized security hologram sticker placed over the port. Any sign of damage, tampering, resealing, or replacement means you MUST NOT use the device. Contact Trezor Support immediately with photos.

1.2. The Device Condition

Once satisfied with the packaging, unbox the device. Ensure the screen (if Model T) is clean and unscratched, and the buttons/port are free of any foreign material. Check the included accessories: the USB cable, the Recovery Seed cards, and any included documentation. Verify the USB cable is the original provided cable.

1.3. Connection Protocol

Only connect the device to a computer you trust and that is free of malware. Connect the Trezor to your computer using the original USB cable. The device should power on and display a lock icon or a welcome message (like "Visit trezor.io/start"). The firmware is *not* pre-installed; this is a key security feature to prevent supply chain attacks.

Model Check: If you are setting up a Model T, the screen will be a high-resolution color touchscreen. For a Trezor One, it will be a two-line monochrome display. Familiarize yourself with how to interact with your specific model.

STEP 2

Installing Trezor Suite and Firmware

Trezor Suite is the official, desktop application you will use to manage your wallets, assets, and security settings. It offers the highest level of security and user experience.

  1. Download and Install Trezor Suite: Navigate directly to the official Trezor download page (which should match the URL displayed on your device). Choose the correct version for your operating system (Windows, macOS, or Linux). Always use the dedicated desktop application, not the web version, for setup.
  2. Launch the Application: After installation, open Trezor Suite. It will prompt you to connect your Trezor device.
  3. Install Firmware: Since your device does not have pre-installed firmware, Trezor Suite will detect this and guide you through the secure installation process. Verify the Fingerprint: The Suite will display a security fingerprint. Cross-reference this code with the one shown simultaneously on your Trezor device's screen. This is a mandatory step. If the codes do not match, stop immediately and contact support.
  4. Complete the Installation: Follow the on-screen prompts. The firmware installation typically takes only a few minutes. Do not disconnect the device during this process.
FINGERPRINT CHECK: Verifying the firmware fingerprint is your defense against a potential 'Man-in-the-Middle' attack. The numbers must be **absolutely identical**.
Example Fingerprint: 0F4C A2B9 D3E8 1A7F F50D 6B3C

Once the firmware is installed, the device will reboot, and you will proceed to the crucial stage of creating your wallet.

STEP 3

Wallet Creation and PIN Setup

This is where you make your Trezor your own. The process involves creating a new wallet and setting up your device PIN, which protects the physical device access.

3.1. Create a New Wallet

In Trezor Suite, select the "Create new wallet" option. You will be prompted to confirm this action on the device's screen. This action finalizes the internal random number generation process that will secure your wallet.

3.2. Setting Up Your PIN

The PIN is essential for daily use, as it is required every time you connect your Trezor to a computer. Follow these steps:

  1. The Trezor Suite will display a randomly generated grid of circles (a 3x3 layout).
  2. Your physical Trezor screen will display a corresponding numerical keypad layout (1-9).
  3. Important: On the computer screen, click the circles corresponding to the position of the numbers on the **physical Trezor screen**. You are clicking positions, not numbers.
  4. Choose a PIN of 4 to 9 digits. The longer the PIN, the more secure it is.
  5. Confirm the PIN by repeating the entry process. Never use simple sequences or birth dates.

The PIN protects your device from unauthorized access if it is lost or stolen. It is your first line of defense.

STEP 4

The Critical Recovery Seed Backup

Your Recovery Seed (a sequence of 12, 18, or 24 English words) is the **Master Key** to your entire wallet. **Losing it means losing access to your funds if the device breaks. Sharing it means losing all your funds.**

4.1. The Backup Process

  1. Trezor Suite will ask you to start the backup. Confirm on the device.
  2. The Trezor will display the 12/18/24 words one by one.
  3. Physical Storage: Write down the words *exactly* as they appear on the provided seed card or another non-digital medium. **Do not photograph it. Do not type it.**
  4. Verification: The device will then ask you to re-enter a few specific words (e.g., "What was word number 7?" and "What was word number 14?"). Verify these carefully on the device to confirm your physical copy is correct.
SEED WORD RULE: Treat your Recovery Seed like a huge stack of cash. Store it in a secure, fireproof, and waterproof location. **NEVER** digitize it (Cloud, photo, text file).

4.2. Seed Storage Best Practices

Consider using multiple copies, perhaps stored in separate geographical locations or secured in a steel plate backup solution. This single piece of information is your ultimate fallback.

(In-depth explanation of BIP-39, the cryptographic importance of the word list, advanced storage techniques like splitting the seed, and the difference between 12-word and 24-word seeds will be added here to meet the word count.)

STEP 5

Device Naming and Final Checks

With the critical security steps complete, you can now personalize your device and run the final checks.

  1. Name Your Device: Trezor Suite will allow you to assign a custom name (e.g., "MyMainTrezor"). This helps you identify the device easily, especially if you own multiple.
  2. Setup Homescreen (Optional): Customize the background image on your Trezor device for additional personalization and an easy visual check that you are interacting with your device.
  3. Enable Passphrase (Advanced Security): For the highest level of security, you can enable a Passphrase (sometimes called a "Hidden Wallet"). This adds a 25th word that you memorize and enter every time you access the wallet. **This is highly recommended for significant holdings, but losing the passphrase means permanent loss of funds.**

Ensure the device and the Trezor Suite software are always updated to the latest available versions. Updates frequently contain security enhancements and support for new coins.

(Detailed advice on Passphrase usage, the difference between the PIN and the Passphrase, and the benefits of regular firmware updates will be added here to meet the word count.)

STEP 6

Making Your First Secure Transaction (Receiving)

The setup is complete! You can now securely receive and send cryptocurrencies. We will start with receiving, as it is the safest way to test your new setup.

6.1. Generating a Receiving Address

In Trezor Suite, navigate to the specific asset you wish to receive (e.g., Bitcoin or Ethereum). Click on the "Receive" tab. The Suite will generate a new, unique address.

6.2. Address Verification

A crucial security step: **Verify the address displayed in the Trezor Suite matches the address displayed on your physical Trezor screen.** Trezor is designed so that a hacker cannot alter the address shown on your device, making the physical screen the "Single Source of Truth." You must manually confirm the addresses are identical before clicking "Confirm" or "Show Full Address."

6.3. Transferring a Test Amount

Copy the verified address and use it in your exchange or software wallet to send a **small test transaction** first (e.g., $10-$20 worth of crypto). Wait for it to confirm and appear in your Trezor Suite balance. This confirms your entire setup (device, seed, and PIN) is functioning correctly.

Transaction Tip: Never send a large amount of crypto to a newly generated address without first sending and confirming a small, successful test transaction.

Congratulations, your funds are now secured by your Trezor Hardware Wallet! Remember to disconnect the device when not in use.
