Trezor Review (2026)

Trezor's Safe 5 uses an EAL6+ certified secure element described as NDA-free, which is the combination that lets a hardware wallet be both chip-certified and genuinely open source. It costs $129 and it has no Bluetooth.

The verdict

The auditable option, and the one to buy if that is why you are shopping. An EAL6+ certified chip without the usual confidentiality agreement resolves the old tension between certification and open source. You pay for it with no Bluetooth and a $129 price.

EAL6+ against EAL5+, and what that actually means

The Trezor Safe 5 uses a secure element certified to EAL6+. The Ledger Nano X uses one certified to EAL5+. These are Common Criteria evaluation assurance levels, and a higher number means the design was subjected to more rigorous formal verification.

The distinction is real but it is not the whole story. An evaluation level describes how thoroughly a chip was assessed, not how well the surrounding system uses it.

What makes the Trezor position more interesting is the second claim: an NDA-free secure element. Secure element vendors have historically required confidentiality agreements that make open-source firmware effectively impossible.

Trezor built its reputation on auditability and long avoided secure elements for exactly that reason. Shipping a certified chip without the usual NDA is the resolution of that tension, and it is the strongest technical argument this product has.

The screen is not a cosmetic upgrade

A 1.54 inch 240 x 240 color display sounds like a comfort feature. It is closer to a security feature, because the entire security model of a hardware wallet rests on you reading what is on that screen before approving.

Verifying a long address character by character on a small monochrome display is genuinely tedious, and tedium is what makes people skip the check.

Address-substitution malware exists precisely because people approve without reading. Anything that makes verification less unpleasant reduces a real attack surface.

This is the clearest practical advantage the Safe 5 holds over cheaper devices, including cheaper Trezors.

What you give up: no Bluetooth

The Safe 5 connects over USB-C only. If you manage crypto primarily from a phone, that is the concrete trade against the Ledger Nano X, which offers Bluetooth.

Desktop-first users lose nothing

If your wallet lives on a laptop, USB-C is simpler and arguably safer than a wireless radio you do not need.

Phone-first users feel it daily

Cabling a device to a phone every time is the kind of friction that leads to leaving assets on an exchange instead.

Some people consider it a feature

No wireless interface means no wireless attack surface. Whether that matters to you is a genuine judgment call rather than a settled fact.

The microSD slot is not storage for your coins

It supports device features rather than holding assets. Your recovery card is still the thing that matters.

Your situation, our answer

If this is you, do this

Auditability is central to your security model

This is the device

Open-source development plus an NDA-free certified secure element is the combination Ledger cannot offer. If that is why you are shopping, stop here.

You manage crypto mainly from a phone

Consider the Nano X instead

No Bluetooth is a real daily cost. Read our Ledger Nano X review and weigh convenience against open firmware honestly.

You verify addresses carefully and often

The screen justifies the price

A color 240 x 240 display makes the security habit that actually protects you far less painful to maintain.

You are protecting under a few hundred dollars

Not yet

At $129 the device costs a meaningful fraction of what you are protecting. A free software wallet is the right call until the balance justifies hardware.

You want the cheapest certified cold storage

Look at the cheaper Trezor models

The Safe 5 premium is mostly the display. Lower models in the same family carry secure elements at a lower price.

The honest ledger

Pros and cons

What we like

  • EAL6+ certified secure element, a higher assurance level than the Nano X
  • NDA-free secure element, which is what makes open source possible here
  • Open-source development model with a long track record
  • 1.54 inch color display makes address verification genuinely easier
  • Gorilla Glass 3 front and a solid physical build
  • Thousands of coins and tokens supported

What to watch

  • No Bluetooth, so phone-first use means cabling every time
  • $129 is a real premium over entry-level hardware wallets
  • Some assets still require a third-party wallet interface
  • The microSD slot is easy to misread as asset storage
  • Open source is a development model, not a personal audit you have performed

How we scored this review

This is a documentary review. Every figure above was read from published documentation on August 16, 2026 and is cited. We did not open a funded account, and we do not claim hands-on testing we did not do.

Scoring rubric with weights
Criterion Weight Mark Why
Security architecture 25% 4.9 The Safe 5 uses an EAL6+ certified secure element, a higher evaluation level than the EAL5+ chip in the Ledger Nano X.
Transparency and auditability 25% 4.8 Open-source development is the product. Trezor describes an NDA-free secure element, which means the chip itself is not hidden behind a confidentiality agreement.
Asset support 15% 4.3 Thousands of coins and tokens supported, though some assets still need a third-party interface.
Hardware and display 15% 4.5 A 1.54 inch 240 x 240 color display behind Gorilla Glass 3, which makes verifying an address materially easier than on a small monochrome screen.
Connectivity and daily use 10% 3.5 USB-C and a microSD slot, but no Bluetooth. Phone-first users lose the convenience the Nano X offers.
Value for money 10% 4.0 Published at $129, which is a real premium over entry-level hardware and buys a certified chip and a proper screen.

What we could not verify

  • The specific secure element chip model. Trezor states EAL6+ certification and NDA-free status but the page we checked on August 16, 2026 did not name the part.
  • The exact count of supported assets. Stated as "thousands" rather than a figure.
  • Which specific assets require a third-party interface rather than Trezor Suite.
  • Battery and physical dimensions, which were not stated on the page we checked.
  • Independent confirmation of the NDA-free claim. It is Trezor's own statement and we have not verified it with the chip vendor.

Trezor FAQs

Is Trezor better than Ledger?

On the two things Trezor optimizes for, yes. The Safe 5 carries an EAL6+ certified secure element against the Nano X's EAL5+, and Trezor's open-source development plus its NDA-free chip mean the security claims are inspectable rather than asserted. Ledger wins on Bluetooth and phone convenience. Neither answer is universal; it depends whether you value auditability or usability more. Read our Ledger Nano X review for the other side.

What does EAL6+ mean?

It is a Common Criteria evaluation assurance level, a standard for how rigorously a security design has been formally verified. Higher numbers mean more rigorous assessment. EAL6+ is a step above the EAL5+ rating on the Ledger Nano X. It describes how thoroughly the chip was evaluated, not how well the rest of the system uses it, so treat it as one input rather than a verdict.

Why does open source matter for a hardware wallet?

Because it changes what you are trusting, with closed firmware you trust a company and a certificate. With open firmware you trust code that security researchers can and do inspect. Neither is automatically safer in practice, but only one of them can be independently checked, and for many buyers that is the whole point of self-custody.

Does the Trezor Safe 5 have Bluetooth?

No. It connects over USB-C only. That is the main practical difference against the Ledger Nano X, and whether it matters depends entirely on whether you manage crypto from a phone or a computer. Some buyers consider the absence of a wireless radio a security advantage rather than a missing feature.

How much is the Trezor Safe 5?

Published at $129 on Trezor's own product page when we checked on August 16, 2026. Prices change and regional pricing varies, so confirm before buying. Buy directly from Trezor rather than a marketplace reseller: supply-chain tampering is a genuine attack against hardware wallets.

Is a hardware wallet worth $129?

It depends entirely on what you are protecting. Spending $129 to secure $200 makes little sense, and a free software wallet is the better call. Spending it to secure several thousand is straightforwardly sensible. The threshold is roughly the point where losing the balance would genuinely upset you. See our beginner wallet guide for the free options worth starting with.

The bottom line

Should you use Trezor?

Buy the Safe 5 if you want cold storage whose security claims can be inspected rather than taken on trust, and you are content to plug in a cable. Buy the Ledger Nano X instead if your crypto life happens on a phone and Bluetooth is worth more to you than open firmware.
