Crypto hardware wallet comparison Trezor Safe 5 vs Coldcard Mk4

Our impressions

Trezor Safe 5

Coldcard Mk4

Pros
  • Small form factor and portable
  • Touchscreen with Gorilla® Glass 3
  • Excellent value at a reasonable price point
not reviewed yet
Cons
  • Requires constant USB connection to operate
  • In our tests touch input was not as accurate as with the older Model T. We experienced situations that felt like lag, where we had to press multiple times, and adjacent letters to the ones we tried to enter. It is not a deal-breaker, but hopefully something that can improve with future firmware updates.

Verdict

The second product in the first line of Trezor products incorporating a secure element. The Trezor flagship model with touchscreen and successor of the Model T. Main difference being, that it lost the convenient magnetic dock, gained a Gorilla® Glass 3 front , snappier hardware, and a minimally sleeker form factor.

Is it worth it?
If you are in the market for a new hardware wallet this seems one of the most secure, versatile, and portable options.Trezor is the most veteran and one of the biggest players in the hardware wallet market for a reason. Their newest products belong to the best products you can get currently.

If you already have a Model T and use wallets with long custom 25th word there is not really a compelling need for the upgrade.

Even if you don’t have a Model T and are looking for a new hardware wallet, the Trezor Safe 3 is a very strong competitor. It too has a Secure Element, is even a tiny bit smaller and easier to carry, and has a phenomenal alternative text input method with two buttons – which does not feel much inferior to touchscreen input TBH. Given that it boasts almost the same feature-set, coin support, and costs less than half the Trezor Safe 5 we feel like the Trezor Safe 3 is the logical choice.

We recommend you go for the Trezor Model 5 only if you prefer touch input, want to make use of the advanced SD card feature, or need to have the latest and shiniest gadget.
