Trezor.io/Start | Starting® Up® Your® Device®

Official, friendly walk-through to unbox, set up, and secure your Trezor hardware wallet (Trezor One & Model T). Follow these steps to start interacting with web3 safely.

Quick start — what this page covers

This guide takes you from unboxing to your first secure transaction: downloading Trezor Suite, initializing the device, writing down your recovery seed, installing firmware and apps, connecting to web services, and following security best practices. It also includes troubleshooting tips and an FAQ for common questions.

Before you begin — essentials

  • Buy only from the official Trezor store or authorized resellers.
  • Use the original USB cable that came with the device (data-capable).
  • Have a pen and the recovery card (or a metal backup) ready to write down your recovery seed.
  • Allocate 15–30 minutes to complete the setup carefully — rushing increases risk.

1) Download Trezor Suite (official app)

Go to the official start page at trezor.io/start and download Trezor Suite for your platform (Windows, macOS, Linux) or get the mobile version from the App Store / Google Play. Trezor Suite is the recommended desktop app to configure your device, manage accounts, and interact with supported blockchains.

2) Unbox & inspect

Check the package for tamper evidence. A sealed and untampered package is the safest starting point. If the seal looks altered, contact Trezor support and the seller before proceeding.

3) Initialize your device

  1. Connect the Trezor device to your computer using the USB cable.
  2. Open Trezor Suite and choose Initialize → Create new wallet.
  3. Follow the on-device instructions: choose a PIN and confirm it. Make sure your PIN is memorable but not trivial.
  4. The device will display your recovery seed (12 or 24 words depending on model/settings). Write these words down EXACTLY in order on the recovery card. Consider using a metal backup for durability.
  5. Confirm the seed when prompted on the device to ensure you've recorded it correctly.

Warning: Never enter your recovery seed into a website or share it. Trezor staff will never ask for your seed.

4) Update firmware and apps

After initialization, check for firmware updates in Trezor Suite. Firmware updates are cryptographically signed — install them when available to ensure your device has the latest security improvements. For certain coins you may need to install specific apps via Trezor Suite.

5) Add accounts & receive funds

Use Trezor Suite to add accounts for Bitcoin, Ethereum, and supported tokens. When receiving funds, always verify the receiving address on your Trezor device screen and confirm the address matches what the app displays. This protects against clipboard or malware-based address tampering.

6) Sending transactions — approve on-device

When you send funds, Trezor Suite will prepare the transaction and the device will display the recipient address and amount. Carefully verify these details on the device screen before approving. For advanced contract interactions (DeFi), review the details and, if uncertain, verify the transaction on a block explorer or use a trusted interface.

Security best practices

  • Official sources: download Trezor Suite and firmware only from trezor.io.
  • Seed protection: never store your recovery seed digitally. Use a metal backup for long-term protection.
  • Device confirmation: always confirm transaction details on the Trezor screen, not just in the app.
  • Minimal exposure: avoid connecting your device on public or untrusted networks and be cautious with browser extensions and third-party apps.
  • Passphrase use: Trezor supports optional passphrases for hidden wallets — use them only if you fully understand the implications (a lost passphrase equals lost funds for that hidden wallet).

Troubleshooting — quick fixes

Device not recognized:
  • Try a different USB cable/port (ensure it's data-capable).
  • Restart Trezor Suite and reconnect the device.
  • Reboot your computer if necessary.
Firmware update errors:
  • Follow on-screen instructions, ensure stable internet, and avoid interrupting the device during updates. If stuck, consult Trezor support.
Mobile pairing (Bridge/WebUSB issues):
  • Use compatible browsers and follow the Trezor Suite mobile pairing guide; enable permissions if prompted.

Advanced topics

Trezor supports advanced features such as passphrases (hidden wallets), integration with third-party wallets and dApps, and developer tools for integrating Trezor support. If you use advanced features, document your setup carefully and keep additional backups for passphrases.

FAQ

Can I recover my funds if I lose my device?
Yes — restore your wallet using the recovery seed on a new Trezor or compatible device.
What should I do if my seed is exposed?
If you suspect your seed was exposed, transfer funds to a new wallet (new seed) as soon as safely possible.
Does Trezor charge fees?
Trezor does not charge transaction fees — network fees apply when broadcasting transactions on blockchains.
