What is Trezor?
Trezor is a hardware wallet designed to provide secure offline storage for cryptocurrencies. Developed by SatoshiLabs in 2014, it was the first hardware wallet ever created. Trezor stores your private keys offline, away from internet-connected devices, significantly reducing the risk of hacking, malware, and phishing attacks. It enables users to safely store, send, and receive digital assets such as Bitcoin, Ethereum, and hundreds of other cryptocurrencies.
As a hardware device, Trezor functions like a small computer that’s built specifically for managing crypto keys. It connects to your PC or mobile via USB, allowing you to authorize transactions while keeping your keys protected within the device.
Why Choose a Hardware Wallet?
Unlike software wallets (apps or browser extensions), hardware wallets like Trezor ensure your private keys never touch the internet. This makes them immune to many common threats like viruses, keyloggers, and remote hackers.
- Offline, tamper-proof environment for key storage
- Trusted display for transaction confirmation
- Recovery options in case of loss or damage
Reminder: If you don’t own your private keys, you don’t truly own your crypto. Trezor puts you in full control.

How Trezor Works
When using Trezor, transaction signing happens inside the device. Here’s how it works:
- You initiate a transaction using the Trezor Suite or supported wallet software.
- The transaction data is sent to the Trezor device via USB.
- You review transaction details on the Trezor display (amount, address, etc.).
- You approve the transaction by physically pressing a button.
- Trezor signs the transaction inside the device and sends the signed version back to your computer for broadcasting.
At no point do the private keys leave the device. Even if your computer is compromised, your keys remain safe.
Setting Up Your Trezor
Initial setup is simple and takes only a few minutes:
- Unbox and connect your Trezor device to a computer.
- Visit the official Trezor website or open the Trezor Suite app.
- Follow on-screen instructions to install firmware and create a wallet.
- Write down your recovery seed and store it safely.
- Set up a secure PIN and optional passphrase.
Once set up, you can send and receive cryptocurrencies directly from the Trezor Suite interface.

Can Trezor be used with MetaMask?
Yes, Trezor can be connected to MetaMask for added security when using DeFi apps or NFTs. The signing still occurs on the hardware device.

Trezor Model One is affordable and supports most major coins. Trezor Model T offers a touchscreen and more advanced features, including Shamir backups and expanded asset support.
