Trezor Safe 5 vs Safe 7

Pick the Safe 5 if a USB-C cable suits you and you want a color touchscreen at the lower price; pick the Safe 7 if you want Bluetooth, a battery with Qi2 charging, a 2.5-inch screen and a second secure element (TROPIC01), at roughly twice the list price on 14 October 2026.

Compared with the Safe 5, the Safe 7 adds Bluetooth, a battery, a larger screen and a second secure element. Both use color touchscreens, Trezor Suite and the same backup formats. On 14 October 2026 Trezor’s comparison page listed the Safe 5 at $129 and the Safe 7 at $249.

Trezor Safe 5 or Safe 7: which one fits?

The Safe 5 fits if you are happy to plug the wallet into a computer, want a color touchscreen with haptic confirmation, and prefer a device with no wireless radio listed in its specifications.

The Safe 7 fits if you want to use the wallet without a cable, want a larger screen, and value a second secure element whose maker publishes its design for review, at the higher list price.

If the price gap matters more than either, the two-button Safe 3 keeps the same backup formats at $59 on the same date; see Trezor Safe 3 vs Safe 5.

What does the Safe 7 add over the Safe 5?

Bluetooth, a battery and wireless charging

The Safe 5 connects over USB-C, which Trezor says carries both power and data; it also lists a microSD card slot. The Safe 7 adds Bluetooth 5.0 or later, Qi2 wireless charging and a LiFePO4 battery rated at 3.2 V and 330 mAh. That removes the cable from everyday use. It also adds a wireless interface that the Safe 5 does not have, and whether that trade matters depends on where and how you sign.

A second secure element

The Safe 5 lists one secure element, certified to EAL6+, which Trezor’s secure element page identifies as the OPTIGA Trust M (V3). The Safe 7 combines two secure elements with a separate microcontroller, which Trezor calls “Three independent layers of security”. The new one is TROPIC01, designed by Tropic Square, which describes it as auditable and open source. Tropic Square calls itself a SatoshiLabs company, and SatoshiLabs says Trezor is part of SatoshiLabs, so the chip maker and wallet maker sit in the same group. The other is an EAL6+ secure element that the Safe 7 product page names as Optiga and the same secure element page identifies as the OPTIGA Trust M (V3) also used in the Safe 5. EAL6 is level six of seven in the Common Criteria, Part 3.

A larger screen

The Safe 5 has a 1.54-inch touchscreen at 240 x 240 pixels. The Safe 7 has a 2.5-inch touchscreen at 520 x 380 pixels.

More size and weight

The Safe 5 measures 65.9 x 40 x 8 mm and weighs 23 g. The Safe 7 measures 75.4 x 44.5 x 8.3 mm and weighs 45 g, nearly twice as much.

A higher list price

The gap was $120 on 14 October 2026. Prices change, so check the date before relying on it.

Is the Trezor Safe 7 more secure than the Safe 5?

The Safe 7 has more documented hardware layers: two secure elements instead of one, one of them open to outside review according to its maker. Both run Trezor’s device software, which Trezor’s security page says “has always been open-source”, and both support a passphrase.

The security records differ in age. Trezor’s disclosure on the November 2024 Ledger Donjon research says the Safe 5 “is not affected” by the supply-chain bypass found on the Safe 3. The Safe 7, launched on 21 October 2025, has its own 2026 record. On 3 June 2026 Ledger Donjon published a laser fault-injection attack on an opened TROPIC01 chip that bypassed its firmware signature check; Trezor’s response says the attack needs physical possession, disassembly and lab equipment, and that compromising TROPIC01 alone does not give access to the PIN or funds. Trezor also published Safe 7 disclosures reported on 22 June 2026 about completing pairing without the on-device code and on 16 August 2026 about authenticity-proof checks; it says the pairing values involved are now rejected and each proof is now bound to its own secure element. The Safe 7 also adds Bluetooth as an interface to study. These disclosures do not establish an overall security ranking between the devices, and we do not rank the two from documentation alone.

What do the Safe 5 and Safe 7 share?

  • Backups. Both offer 12- and 24-word BIP39 backups and a 20-word SLIP-39 backup, which Trezor’s backup guide names as the default on both. Trezor’s SLIP39 FAQ lists both for Multi-share Backup, with firmware 2.7.2 or newer. A 20-word SLIP39 backup needs SLIP39-compatible recovery; see our seed phrase guide.
  • Passphrase. Supported on both.
  • App and coins. Both use Trezor Suite. Trezor says each handles thousands of coins and tokens; for the Safe 7 it names BTC, ETH, SOL, Arbitrum and USDC as examples. Each has a Bitcoin-only edition.
  • Multisig. Neither does it directly in Trezor Suite; Trezor points to compatible third-party software.
  • Touch input. Both use color touchscreens.

What we could not verify

  • Safe 7 country of manufacture. We found no model-specific statement. A February 2025 forum reply covering earlier models names the Czech Republic for the Safe 5.
  • Safe 7 battery life. Our records hold capacity, not runtime.
  • Safe 5 battery. Trezor says it is powered over USB-C but does not state outright that it has no battery.
  • Bluetooth platform support. Which phones and operating systems pair with the Safe 7 is not recorded in our dataset.

Every documented event our dataset lists for each model, placed by date. The count includes maker-level events that predate a model, as the scope line says. An empty row means we found no documented event, not that none exists.

  • Trezor Safe 5 3 events

    3 events, 17 Jan 2024 to 23 Jun 2025
    1. Trezor support-form impersonation. Attackers abused support replies for phishing. Trezor said the issue was contained and the phishing site removed. src
    2. Safe 3 research, explicit Safe 5 exclusion. Trezor states Safe 5 was not affected by the reported Safe 3 supply-chain bypass because it uses a newer MCU. src
    3. Historical Trezor support-portal incident. Unauthorized portal access enabled seed phishing. Trezor restricted access and warned affected users. This predates Safe 5. src
  • Trezor Safe 7 5 events

    5 events, 17 Jan 2024 to 16 Aug 2026
    1. Safe 7 secure element authenticity checks, date reported. Trezor's security portal says Safe 7 authenticity proofs were verified against a combined key set rather than per secure element, so one valid proof could satisfy all three checks. Trezor says each proof is now bound to its own element. src
    2. Safe 7 host pairing (Trezor Host Protocol), date reported. Trezor's security portal says a host could complete Safe 7 pairing without the code shown on the device by supplying a degenerate value in the pairing key exchange. Trezor says such values are now rejected. src
    3. TROPIC01 secure element in the Safe 7, physical lab attack. Ledger Donjon published a laser fault-injection attack on an opened TROPIC01 chip that bypassed its firmware check and could extract a secret tied to its PIN functions. Trezor says it needs physical possession and lab equipment, that TROPIC01 alone does not give access to the PIN or funds, and that users need not act; a full firmware fix cannot be applied remotely. src
    4. Historical Trezor support-form impersonation. Attackers abused support replies for phishing. Trezor said the issue was contained and the phishing site removed. src
    5. Historical Trezor support-portal incident, not Safe 7 hardware. Unauthorized portal access enabled seed phishing. Trezor restricted access and warned affected users. src
