Welcome to the world of self-custody. By purchasing a Trezor device, you have taken the most significant step toward securing your digital assets. Unlike software wallets (hot wallets) that live on internet-connected devices like phones or laptops, a hardware wallet (cold storage) keeps your private keys offline at all times.
The philosophy behind the Trezor ecosystem is simple: Don't trust, verify. The device acts as a secure isolation environment. Even if your computer is infected with malware, keyloggers, or viruses, your private keys remain safe inside the Trezor device. The device only communicates public data to the computer, requiring physical confirmation on the device screen for any transaction to occur.
The setup process is the most critical phase of your ownership. This is where you generate your master key (Recovery Seed) and establish the security protocols that will protect your funds for years to come. This guide will walk you through the official initialization process found at the standard start URL, ensuring you do not fall victim to phishing attempts or setup errors.
Before you even plug your device into a computer, you must perform a physical inspection. Supply chain attacks, though rare, are a theoretical vector where a device is intercepted and modified before reaching the user. Trezor mitigates this with holographic tamper-evident seals.
Do not use the device if the holographic seal is broken, missing, or looks like it has been peeled off and reapplied.
The Trezor Model One comes in a box wrapped in plastic foil or has a tamper-evident hologram on the box opening (depending on the batch version). Ensure the box is intact.
The Model T has a holographic seal covering the USB-C port on the device itself. This seal leaves a sticky residue if removed. If there is no hologram over the USB port when you first take it out of the box, contact support immediately.

To communicate with the blockchain, your device needs an interface. Trezor has transitioned from the old web wallet to a robust desktop application called Trezor Suite.
Open your browser and navigate manually to trezor.io/start. Select your device model and download the Trezor Suite app for your operating system (Windows, macOS, or Linux). There is also a web version, but the desktop application is generally recommended for better security and phishing protection.
If you are using the web version, you may be asked to install the "Trezor Bridge," which is a communication driver allowing the browser to talk to the USB device. The desktop app has this built-in.
Plug your Trezor into your computer using the provided USB cable. The device screen should light up, displaying the Trezor logo or a welcome message.
Trezor devices are shipped without firmware installed. This is a security feature. It ensures that the software running on your device is the latest, official version signed by SatoshiLabs, and has not been modified by a middleman.
Once you open Trezor Suite and connect your device, the software will prompt you to Install Firmware.
Fingerprint Verification (Model T): During this process, the Trezor Suite may display a "firmware fingerprint" (a string of characters). You should compare this with the string shown on your physical Trezor device screen. If they match, the software is genuine.
After the firmware is installed, Trezor Suite will offer two options:
Select Create New Wallet. The device will generate a unique "Seed" internally using a Random Number Generator (RNG). This seed is the master key to all your crypto assets.
This is the most critical step in the entire presentation. If you break your device, lose it, or if it is stolen, the Recovery Seed is the ONLY way to get your money back.
The Trezor will display a sequence of words (usually 12, 18, or 24 words) on its small screen. You must write these down, in order, on the provided paper cards.
Trezor Suite will ask you to verify the seed. For the Model One, the computer will ask for specific words (e.g., "What is the 5th word?"), but you must never type the full seed on the PC during setup. For the Model T, the verification happens entirely on the touchscreen of the device.
You will be asked to set a PIN code. This protects the physical device from unauthorized use. If someone steals your Trezor, they cannot use it without the PIN.
The PIN wipes the device after roughly 16 incorrect attempts, protecting you from brute-force attacks.
Once you are comfortable, you can enable the "Passphrase" feature. This acts as a "25th word" added to your seed.
This creates a hidden wallet. Even if someone finds your 24-word seed, they cannot access the funds in the hidden wallet without the specific passphrase you memorized.
Once setup is complete, you will enter the Dashboard. Here is a quick tour of the interface:
On the left sidebar, you can enable various coins (Bitcoin, Ethereum, Litecoin, etc.). Click the "+" symbol to add a new coin account. Each account has its own transaction history and balance.
To fund your wallet:
To send money, paste the recipient address and amount. You will be asked to confirm the transaction on the physical Trezor device. You must physically click the button on the device to sign the transaction.
Congratulations! You have successfully initialized your Trezor device via trezor.io/start. You are now your own bank.
Hardware wallets offer the highest standard of crypto security, but they rely on the user to keep the Recovery Seed offline. By following this guide, you have established a fortress for your digital wealth.
