Trezor Safe 3 vs Safe 5 vs Safe 7: Which Trezor Should You Buy?

This article contains affiliate links.

Trezor currently sells three hardware wallets: the Safe 3, the Safe 5 and the Safe 7. All three protect your keys with an EAL6+ certified secure element, run open-source firmware and support the same backup options. The differences are in how you use them: the Safe 3 has two buttons and a small screen, the Safe 5 adds a colour touchscreen, and the Safe 7 adds Bluetooth, a battery, a larger screen and a second secure chip.

In short: the Safe 3 for a first device on a laptop, the Safe 5 if you want a screen you can read comfortably, and the Safe 7 if you mostly use an iPhone or want wireless use. The rest of this comparison explains why.

Prices quoted are Trezor’s regular list prices on trezor.io (€59, €129 and €249). At the start of November 2026 the shop was running a promotion with prices about 15% lower (roughly €50, €109 and €211). Promotions come and go, so check the shop before you buy.

What all three have in common

It is worth starting here, because the shared features are the ones that protect your money:

• A certified secure element. Each model uses an EAL6+ certified chip (Infineon’s OPTIGA Trust M) to protect against physical attacks, such as someone stealing the device and trying to extract the keys.
• Open-source firmware. Trezor publishes its firmware code, so independent researchers can review it.
• On-device confirmation. Every transaction is shown on the device’s own screen and needs your physical confirmation.
• The same backup options. Standard 12-, 20- or 24-word backups and multi-share backups, where the backup is split into shares and a minimum number is needed to restore. Keep in mind that your backup matters more than the model you pick.
• The same app. All three work with Trezor Suite and with compatible third-party wallets.

Put simply, the Safe 3 is not an “unsafe” budget option. It saves money on comfort, not on the core security model.

Trezor Safe 3: the sensible first device

The Safe 3 is small (59 × 32 mm, 14 g) and runs entirely on its two buttons. You scroll through addresses and confirm with a press.

Good to know:

• The 0.96″ monochrome screen is readable, but checking a long address or a complex transaction takes patience.
• It connects by USB-C only. On a computer that is no problem. On an iPhone, Trezor Suite offers only limited functions with this model.
• It is the cheapest way to hold your own keys with Trezor’s current security design.

Choose the Safe 3 if you are new to self-custody, mainly use a laptop or desktop, and sign transactions now and then rather than every day.

Trezor Safe 5: the comfortable middle

The Safe 5 keeps the Safe 3’s security approach and adds a 1.54″ colour touchscreen protected by Gorilla Glass 3, with haptic feedback when you tap. It also has a microSD card slot, which can be used for SD card protection of the device.

What the extra €70 buys:

• Much easier reading of addresses and transaction details, which matters for spotting a wrong address or a suspicious request;
• PIN and passphrase entry on the touchscreen, which feels quicker than button navigation;
• A slightly larger, more solid feel (65.9 × 40 mm, 23 g).

What it does not change: it is still USB-C only, and iPhone support in Trezor Suite is as limited as on the Safe 3.

Choose the Safe 5 if you use your wallet regularly, interact with apps or tokens where reading details on screen matters, or simply want the more pleasant device.

Trezor Safe 7: wireless and built to last

The Safe 7 is Trezor’s flagship. It brings the biggest changes in the range:

• Bluetooth, with encrypted communication between the device and app, alongside USB-C;
• A built-in battery and Qi2 wireless charging, so it works without a cable;
• Full iPhone support in Trezor Suite, which the other two models lack;
• A 2.5″ high-resolution touchscreen (520 × 380), the largest in the range;
• A second secure element, TROPIC01, in addition to the EAL6+ chip, plus a hardened main processor. Trezor describes this as three layers of hardware security, and says the device is designed to receive quantum-resistant updates in future;
• An aluminium body with IP54 protection against dust and water splashes.

The trade-offs: it costs roughly twice as much as the Safe 5, it is the heaviest at 45 g, and Bluetooth is one more interface. Trezor secures the connection and every action still needs your confirmation on the device, so this is a matter of preference rather than a weakness. Note that Trezor lists an operating temperature range of 0 to 45 °C for the Safe 7, narrower than for the Safe 5, which may matter if you keep it in a cold place.

Choose the Safe 7 if your phone, especially an iPhone, is your main device, you want to sign without cables, or you want the most robust build.

Which one should you buy?

• First hardware wallet, laptop user, modest budget: Safe 3.
• You check transactions often or use DeFi apps: Safe 5.
• iPhone first, or you want wireless use: Safe 7.
• You only hold bitcoin: any of the three in the Bitcoin-only edition, which removes support for other coins to reduce the attack surface.
• You are not sure you need a hardware wallet yet: if you hold a small amount on a licensed exchange, you may not. Our explainer on hardware wallets helps you decide.

If you want to compare Trezor with Ledger and other brands, our EU buyer’s guide to hardware wallets covers the main alternatives. If you would rather have a Swiss-made device, the BitBox02 Nova also has fully open-source firmware and comes in multi-coin and Bitcoin-only editions.

What each model really costs: a worked example

A hardware wallet is a one-off purchase, but a sensible setup also includes a durable backup, and most people replace a device after some years. The figures below are a hypothetical example to show how to think about cost, not advice to spend a particular amount.

Assume you keep the device for five years and add Trezor’s Keep Metal steel backup (€99 regular list price for the 20-word version). Using regular list prices:

	Safe 3	Safe 5	Safe 7
Device	€59	€129	€249
Metal backup	€99	€99	€99
Total	€158	€228	€348
Per year over five years	€31.60	€45.60	€69.60
Per year, as a share of €3,000 in crypto	1.05%	1.52%	2.32%
Per year, as a share of €30,000 in crypto	0.11%	0.15%	0.23%

Three things stand out:

• With a hypothetical €3,000 in self-custody, the Safe 7 costs more than twice as much per year as the Safe 3 for the same core security. The extra money buys comfort and convenience, not more protection for your keys.
• With €30,000, the gap between the models shrinks to about a tenth of a percent a year. At that point, picking the device you will use correctly every time matters far more than the price.
• With, say, €300 in crypto, a €158 setup is more than half of what you are protecting. A licensed exchange or a carefully used software wallet may be the more proportionate choice until the amount grows.

Honest downsides

No Trezor model is perfect. These are the drawbacks worth knowing before you buy:

• Safe 3: the small monochrome screen makes checking long addresses tedious, and on an iPhone, Trezor Suite only lets you check balances, buy and receive. You cannot send from an iPhone with it.
• Safe 5: the same limited iPhone support as the Safe 3, at more than twice the price. If iPhone use is your reason to upgrade, the Safe 5 does not solve it.
• Safe 7: the most expensive and heaviest model, and the only one with a battery, which will age over the years. Its listed operating temperature range is narrower than the others’.
• All three: some smaller networks work only through third-party wallets, not in Trezor Suite itself, so check your coins on trezor.io first. Trezor offers no paid recovery service: if you lose both the device and the backup, nobody can help. And, like every well-known brand, Trezor’s customers are targeted by phishing emails and fake “support” accounts.

Buying tips

• Buy from trezor.io or an authorised reseller, never from a marketplace or second-hand.
• Check the tamper-evident seal when it arrives, and always create a new recovery phrase yourself. A pre-filled phrase in the box means a scam; see our guide on how to spot crypto scams.
• Plan your backup before the device arrives: paper to start with, metal if the amount matters.
• Budget for the backup too. At list price, Trezor’s own steel backup plate costs more than a Safe 3.
