Trezor Trezor Safe 7
A plan byTrezor
Trezor, made by SatoshiLabs (Czech Republic), is the first hardware wallet ever sold and one of the most respected for transparency: firmware and design are open-source and auditable. The current lineup starts with the Safe 3 (≈€59) with an EAL6+ certified secure element and two buttons, moves up to the Safe 5 (≈€129) with a colour touchscreen and haptic feedback, and tops out with the Safe 7 (≈€249) with Bluetooth, Qi2 wireless charging and the auditable TROPIC01 chip. Every model also comes in a Bitcoin-only edition. Devices are managed through the Trezor Suite app (desktop and web), which also integrates buy/sell/swap (Invity) and staking for ADA, ETH, SOL and TRX. The legacy Model One and Model T have been discontinued.

Strengths
- Auditable open-source firmware and design; EAL6+ secure element on Safe models; mature Trezor Suite app; industry pioneer with a long track record.
- Self-custody: funds stay in your wallet — the platform cannot touch them.
- No KYC: usable without identity verification.
- Open-source, verifiable code.
- Self-hostable: you can run your own instance or node.
Weaknesses
- USB-C connection (Bluetooth on the Safe 7), not air-gapped; the Model One and Model T have been discontinued; coin support mainly handled via Suite; buying and swapping inside Suite carries third-party provider fees plus a Trezor commission.
- No notable sovereignty drawback documented.
Verdict
Score 4.5/5, outstanding profile. In its favour: auditable open-source firmware and design; EAL6+ secure element on Safe models; mature Trezor Suite app; industry pioneer with a long track record. The trade-off to weigh: uSB-C connection (Bluetooth on the Safe 7), not air-gapped; the Model One and Model T have been discontinued; coin support mainly handled via Suite; buying and swapping inside Suite carries third-party provider fees plus a Trezor commission.
On the Sovereignty lens the score is 4.8/5 (outstanding): the strength is fund control (5.0/5), while privacy & anonymity (4.5/5) is the weak link.

FAQ
How much does a Trezor cost?
The entry-level Safe 3 costs about €59 ($59 on the official shop). The Safe 5 with a colour touchscreen costs about €129, and the flagship Safe 7, with Bluetooth and wireless charging, about €249. The older Model One and Model T are no longer sold.
Is Trezor open source?
Yes, largely so: firmware, software and hardware design are public and auditable. This is one of the brand's historic strengths versus competitors with closed-source firmware.
Does Trezor have a secure element?
The Safe 3, Safe 5 and Safe 7 use an EAL6+ certified secure element; the Safe 7 also adds the TROPIC01 chip, which Trezor presents as the first auditable secure element. The older Model One, now discontinued, had none and relied on the microcontroller alone.

Update history
- reputazione Not affected by the 30 Jul 2026 Coldcard exploit (an entropy flaw specific to that firmware): Trezor stated user funds are safe, different randomness-generator design.
- reputazione TROPIC01 chip vulnerability (Safe 7) and a Safe 3 disclosure, found in lab conditions by Ledger Donjon (laser fault injection: requires physical access and advanced equipment). No real-world attack, funds safe, transparent handling via responsible disclosure.
