Trezor.io/Start — Securely Onboard with Trezor

This practical guide walks you step-by-step through buying, setting up, and using your Trezor hardware wallet. We'll cover setup, seed phrase safety, everyday transactions, DeFi compatibility, troubleshooting, and best practices to keep your crypto truly yours.

Beginner-Friendly

Clear setup steps, test transactions, and simple security rules.

Cold Storage

Trezor keeps your private keys offline — essential for long-term safety.

DeFi & More

Use Trezor with wallets and bridges to interact with DeFi securely.

Why Trezor.io/Start is your first step

Trezor.io/Start is the official onboarding route for Trezor devices (Trezor One, Trezor Model T, and other hardware). It ensures you download authentic software, follow verified steps for initialization, and avoid phishing or clone sites — the most common cause of lost funds. In simple words: always start at Trezor.io/Start.

Quick fact: The private key never leaves the Trezor device — all signing happens locally on the device screen, making man-in-the-middle or clipboard malware ineffective.

Step-by-step setup (safe and repeatable)

  1. Buy from official sellers: Purchase from Trezor.io or verified resellers.
  2. Visit Trezor.io/Start: Type the address manually — don't click search ads.
  3. Download Trezor Suite: The official app handles firmware, accounts, and pairing.
  4. Initialize the device: Choose "Create new wallet", set a PIN, and write down your seed (mnemonic) carefully.
  5. Verify the seed on-device: Never enter the seed into any app — verify words shown on Trezor screen.
  6. Test with a small amount: Send a tiny amount first to ensure the receive flow is correct.
  7. Return to cold storage: For long holdings, keep coins on Trezor and use hot wallets only for small, active sums.

Seed phrase and backup best practices

The seed (recovery phrase) is your ultimate key. Treat it like the master key to a vault — if lost or exposed, funds are irrecoverable. Best practices:

  • Never store seed digitally: No photos, no notes in cloud drives, no screenshots.
  • Use durable storage: Consider metal backup plates resistant to fire, water, and corrosion.
  • Distribute with caution: If you split the seed across locations, ensure reconstruction is possible only with strict safety measures.
  • If exposed — migrate: If you suspect anyone ever saw your seed, create a fresh wallet and transfer funds immediately.

Sending & receiving — common pitfalls

Before approving any transaction, confirm values on the Trezor device screen. Many malware attacks try to replace addresses or amounts within wallets; the on-device confirmation is the single source of truth.

Verify on-device

Always match the first and last characters of the address shown on the device to the app.

Gas & fees

Use Trezor Suite or your wallet's recommended presets. For DeFi, estimate gas carefully.

Test transfers

Use a tiny test transfer before moving large balances.

Case study: Recovering from a phishing attempt

A user clicked a malicious link and was prompted to "restore" their wallet on a fake page. Because the user only used Trezor for cold storage and never typed the seed anywhere, the attacker couldn't access funds. This highlights the simplest rule: never enter your seed into a website or app.

Troubleshooting — common errors & fixes

  • Device not recognized: Try a different USB cable/port, ensure Trezor Suite is up to date, and check browser bridge if applicable.
  • Recovery check failed: Reboot and try again; ensure correct word order and spacing when restoring.
  • Phishing URL or fake app: Close the page, never enter words, and verify the official Trezor domain if in doubt.

Can I restore my Trezor on another device?
