Trezor Safe 3 vs Safe 5
Pick the Safe 3 if the lower list price matters more than the screen and two buttons are enough for you; pick the Safe 5 for a color touchscreen with haptic feedback and a microcontroller that Trezor says was not affected by the 2024 Safe 3 supply-chain finding.

Side B · Safe 5
-
From its datasheet Suits people who want a color touchscreen with haptic confirmation on a Trezor that connects by USB-C cable, and who do not need Bluetooth or wireless charging.
- Open-source firmware
- Bitcoin-only edition
- Touchscreen (not listed on the Safe 3 side)
Chips are shown only where the device's spec record supports them: open-source firmware, a Bitcoin-only edition, QR or air-gapped signing, Bluetooth, NFC, a built-in battery and a touchscreen. A missing chip means the record does not list the feature or we could not verify it.

The Safe 3 and Safe 5 share Trezor’s security model, backup formats and app. They differ in the screen and input, size and price, and the Safe 5 uses a more recent microcontroller than the original Safe 3. On 14 October 2026 Trezor’s comparison page listed the Safe 3 at $59 and the Safe 5 at $129.
Trezor Safe 3 or Safe 5: which one fits?
The Safe 3 fits if you want Trezor’s open-source software, an EAL6+ certified secure element and a choice of BIP39 or SLIP39 backups at the lower outlay, and you are comfortable confirming actions with two buttons on a small monochrome screen.
The Safe 5 fits if you want to read and approve transactions on a color touchscreen, with haptic confirmation, and you prefer the model Trezor names as unaffected by the supply-chain research published on the Safe 3.
Neither lists Bluetooth or a battery. If you want both, the Safe 7 is the Trezor that has them; see Trezor Safe 5 vs Safe 7.
What does the Safe 5 add over the Safe 3?
A color touchscreen with haptic feedback
The Safe 3 uses a 0.96-inch monochrome OLED at 128 x 64 pixels and a two-button pad. The Safe 5 uses a 1.54-inch color touchscreen at 240 x 240 pixels, and Trezor describes “confirmation haptic feedback” when you approve an action. This is the difference you meet every time you use the device.
A different microcontroller from the original Safe 3
On 12 November 2024 Ledger Donjon, the security lab of rival maker Ledger, reported that some Safe 3 countermeasures against supply chain attacks could be bypassed. In this case, the threat is tampering with a device before it reaches its owner. Trezor’s disclosure says the Safe 5 is not affected because it uses a more recent microcontroller. The report was not described as extracting keys from a wallet already set up and locked. Trezor’s developer documentation also says the Safe 3 “was upgraded post-release” and now exists in two chip variants. Our records do not compare the upgraded Safe 3 chip with the Safe 5’s.
A microSD card slot
Trezor lists a microSD card slot on the Safe 5. The Safe 3 lists USB-C only. Our records do not say what the slot is used for.
More size and weight
The Safe 3 measures 59 x 32 x 7.4 mm and weighs 14 g. The Safe 5 measures 65.9 x 40 x 8 mm and weighs 23 g.
A higher list price
The gap was $70 on 14 October 2026. Prices change; the date is part of the figure.
Is the Trezor Safe 5 more secure than the Safe 3?
On paper the two share most of their protections. Both list a secure element certified to EAL6+, and Trezor’s secure element page names the same chip for both, the OPTIGA Trust M (V3). EAL6 is level six of seven in the Common Criteria, Part 3, which lets a level be augmented by adding assurance components or by substituting higher-level ones. Both run Trezor’s device software, which Trezor’s security page says “has always been open-source”. Both support a passphrase.
The documented difference is the microcontroller and the 2024 supply-chain finding above, which concerned the original Safe 3 hardware. Both models share the brand-level phishing incidents involving Trezor’s support systems in January 2024 and June 2025; the January 2024 one predates the Safe 5. Trezor restricted support-portal access and warned affected users after the first, and said the second was contained and the phishing site taken down. Beyond that, documentation alone does not let us rank the two on overall security, and we do not try.
What do the Safe 3 and Safe 5 have in common?
- Backups. Both offer 12- and 24-word BIP39 backups and a 20-word SLIP-39 backup. Trezor’s backup guide says the 20-word Single-share Backup is the default on both (on the Safe 3 since June 2024). A SLIP39 backup needs SLIP39-compatible recovery; BIP39 restores on most other wallets. Our seed phrase guide explains the difference.
- Multi-share Backup. Trezor’s SLIP39 FAQ lists both, with firmware 2.7.2 or newer.
- App and coins. Both use Trezor Suite, and Trezor says each manages “1000s of coins & tokens”. Each has a Bitcoin-only edition.
- Multisig. Neither does it directly in Trezor Suite; Trezor points to compatible third-party software.
- Connection and power. Both connect over USB-C and take power from it.
- Origin. A February 2025 reply on Trezor’s forum says Trezor devices are made in the Czech Republic.

What we could not verify
- Safe 5 battery. Trezor says the Safe 5 is powered over USB-C but the pages we checked do not state that it has no battery. The Safe 3 FAQ says plainly that it has none.
- Which Safe 3 chip variant a given unit has. We found no buyer-facing way to tell.
- What the Safe 5’s microSD slot does. Not recorded in our dataset.

- Trezor support-form impersonation campaign. Attackers abused support replies for phishing. Trezor said the issue was contained and the phishing site removed. src
- Original Safe 3 supply-chain countermeasures. Ledger Donjon demonstrated a bypass of some supply-chain countermeasures. This was not described as extraction from an initialized, locked wallet. Later Safe 3 hardware uses an upgraded MCU. src
- Trezor support portal, brand-level. Unauthorized portal access enabled seed-phishing messages. Trezor restricted access and warned affected users. src
