Trezor Cold Wallets

Trezor hardware wallets are self-custody devices designed to keep cryptocurrency private keys offline while allowing secure transaction review and approval directly on the device.

This page explains Trezor’s current hardware wallet lineup, how the models differ, and which features matter depending on how you plan to use cold storage. The goal is clarity and understanding — not recommendations or financial advice.

What is a Trezor hardware wallet?

A Trezor wallet is a type of cold storage device that generates and stores private keys inside dedicated hardware rather than on an internet-connected phone or computer.

When a transaction is made, the details are shown on the Trezor device and must be confirmed directly on the hardware. This keeps private keys isolated and reduces exposure to online threats such as malware and phishing.

Trezor devices work with Trezor Suite and compatible third-party wallet software to manage supported assets while keeping signing on the device itself.

Trezor wallet models — overview

Trezor currently offers three primary hardware wallet models: Safe 3, Safe 5, and Safe 7. All three follow the same core self-custody principles but differ in interface, display, and security architecture.

Choosing between them depends largely on how you prefer to interact with a device and how much on-device visibility you want when approving transactions.

Trezor Safe 3 — simple, button-based cold storage

The Trezor Safe 3 is a straightforward hardware wallet that uses a monochrome display and physical buttons for transaction review and confirmation.

The Trezor Safe 5 builds on the Safe 3 by introducing a color touchscreen for transaction review and device interaction. This removes the need for physical buttons and allows for more intuitive navigation during setup and daily use.

Like other Trezor devices, private keys remain offline and transactions must be confirmed directly on the device.

Key characteristics:
• Offline private key storage

• USB-C connectivity

The Safe 7 combines multiple security components with a modern interface while maintaining the same core self-custody principles as other Trezor wallets.

Key characteristics:

• Large touchscreen display
• USB-C connectivity
• Enhanced security architecture
• Recovery seed and passphrase support

Good fit if you:

Note: All models require secure offline storage of the recovery seed. Display and interface differences affect usability, not custody ownership.

How to choose between Trezor wallets

All Trezor wallets provide offline private key storage and require on-device transaction confirmation. The main differences are how you interact with the device.

• Safe 3 prioritizes simplicity and physical buttons
• Safe 5 adds touchscreen convenience
• Safe 7 offers the largest display and enhanced security design

None of these devices remove the need to securely store your recovery seed phrase.

Trezor hardware wallets — common questionsClear answers for beginners about security, setup, and recovery

What is a recovery seed?

A recovery seed is a list of words generated during wallet setup. It is the only way to recover your funds if the device is lost or damaged.

Do Trezor wallets connect to the internet?

The device itself does not connect to the internet. A computer or phone prepares transactions, but signing happens offline on the device.

What happens if I lose my Trezor?

Funds can be restored on another compatible wallet using the recovery seed. If both the device and seed are lost, funds cannot be recovered.

Are Trezor wallets suitable for beginners?

They can be, as long as the user understands the responsibility of securely storing the recovery seed.

Trezor accessories for recovery seed protection

Trezor also offers accessories designed to help protect your recovery seed phrase. These accessories do not store private keys themselves.

Common options include:
• **Trezor Keep Metal** (20-word or 24-word) stainless steel backup plates
• Protective cases for hardware wallets
• USB-C cables and screen protectors

Seed backup tools are optional but help protect recovery phrases from fire, water, and physical damage.
