Trezor® Wallet — Secure Bitcoin & Crypto Storage™

Hardware security for your digital assets. Trezor devices are purpose-built to keep private keys offline and under your control — protecting Bitcoin, Ethereum and thousands of other cryptocurrencies from online threats.

What is a Trezor® hardware wallet?

A Trezor® hardware wallet is a small, tamper-resistant device that stores the private keys used to sign cryptocurrency transactions. Unlike exchange wallets or software wallets that keep keys on internet-connected devices, a hardware wallet isolates keys inside secure hardware so that signing operations happen offline. Trezor pioneered accessible, open hardware security for individuals and institutions who want to own — not just hold — their crypto.

Core security features

Cold storage & offline signing

Private keys never leave the device. Transactions are created on your computer but signed within the Trezor and only the signed transaction is shared.

Recovery seed (BIP39)

During setup you generate a mnemonic recovery phrase — a human-readable backup that can restore your wallet if the device is lost or damaged. Securely store this seed offline.

PIN protection & passphrase

A PIN prevents casual access. Optional passphrases create hidden wallets for plausible deniability and stronger security.

Open-source firmware

Trezor publishes firmware and software code openly so the community can audit it for security and correctness.

Why choose Trezor?

Trezor strikes a practical balance between usability and security. It supports many mainstream coins and tokens, integrates with major wallets and DeFi tools, and offers a clear recovery model. For users who want long-term custody without trusting custodial services, a Trezor device is a resilient choice.

Quick setup: getting started

The following high-level steps show how to set up a new Trezor device. Always follow the official manufacturer instructions that come with your device.

  1. Unbox the device and verify packaging for tamper indicators.
  2. Connect the Trezor to your computer and open the official Trezor Suite or web interface.
  3. Create a new wallet and write down your recovery seed on the provided card — do not store it digitally.
  4. Choose a PIN and optionally enable a passphrase for an additional hidden wallet.
  5. Update the firmware if prompted to ensure you have the latest security fixes.

After setup, transfer a small amount first to verify everything is working before moving larger balances.

How Trezor fits into your overall security plan

A hardware wallet is one layer of a multi-layered security approach. Combine it with secure habits: use a strong, unique PIN; never type your seed into a connected device; store backups in separate physical locations; and enable passphrases for sensitive holdings. Consider multisig arrangements if you need higher institutional controls or shared custody.

Using Trezor with wallets and services

Trezor integrates with wallets and services for convenience while keeping keys offline. You can use it with the Trezor Suite desktop app, browser extensions, and third-party wallets that support hardware devices. When interacting with DeFi or exchanges, the signing still happens on the device — even for complex smart contract interactions, Trezor displays transaction details for your approval on its screen.
