The short answer

The Safe 3 has the same security model as the Safe 5 — certified secure element, fully open firmware, Shamir backup — at around $80. What you give up is screen size, which matters when verifying contract interactions rather than simple sends.

Recommendable to most readers, with stated caveats. The headline 8.7 is the weighted mean of these marks — see our methodology. Not financial advice.

What we liked

  • Same secure element and open stack as the flagship
  • Shamir backup support for split recovery
  • Excellent value at around $80

Where it falls short

  • Small monochrome screen makes complex transactions harder to verify
  • Shares the vendor's 2022 customer data breach history

For most users the Safe 3 is the right Trezor. It closes the physical-extraction weakness of the older models with a secure element, keeps the fully open firmware that has always distinguished Trezor, and costs roughly half what the flagship does.

Where the saving shows

The screen. It is small and monochrome, with two physical buttons. For sending bitcoin to a verified address that is fine. For approving a complex contract interaction on Ethereum, a small display is where blind signing habits form — people scroll rather than read. If you interact with DeFi regularly, the extra spend on a Safe 5 or a Keystone buys real safety rather than comfort.

What you get

Bitcoin, Ethereum, ERC-20 tokens and a wide asset list through Trezor Suite and third-party wallets; passphrase support for hidden wallets; Shamir backup for split recovery; and firmware that anyone can read and build.

Vendor considerations

The 2022 third-party support vendor breach that leaked customer contact data applies to Trezor as a company, and phishing aimed at Trezor owners remains common. Buy directly from the manufacturer, verify the packaging, and never enter a seed phrase into anything but the device itself.

Who should use it

Anyone wanting verifiable open firmware with modern physical security at a reasonable price, whose usage is mostly holding and sending rather than heavy contract interaction.

FAQ

What is the difference between Safe 3 and Safe 5?
The security model is identical — same secure element, same open firmware. The Safe 5 adds a large colour touchscreen, which matters mainly for verifying complex transactions.
Does the Safe 3 support Ethereum and tokens?
Yes, through Trezor Suite and third-party wallets including MetaMask and Rabby, alongside Bitcoin and a wide list of other assets.
Is $80 enough for a secure hardware wallet?
Yes. The Safe 3 has a certified secure element and open firmware; the more expensive devices buy screen size, air gapping or wider coverage rather than fundamentally better key security.
Where should I buy a Trezor?
Directly from the manufacturer. Second-hand or third-party marketplace devices carry supply-chain risk that no security feature can mitigate.
