Trezor 3 Safe is a boring name, I expected something more exotic but in reality it is just upgraded Trezor model One, and maybe that is not such a bad thing.
Trezor added usb-c connection, instead of old micro-usb used on model One, and they added EAL6+ Secure Element,
but I can't find information what exact model they are using and it's OPTIGA Trust M.
I also don't know what main processor they are using for Trezor 3, but it should support Monero coin, unlike Trezor One, so it's probably similar like processor from Trezor model T.
Price for Trezor 3 is $79 and I think that is not bad, but don't expect to have bigger screen with Trezor 3, it's the same size as in Trezor One.
If you don't own hardware wallet this would be a solid entry point that will stay updated well after Trezor One gets retired.
Trezor 3 is in a sense just replacement for Model One.
Note that the secure element is not open source. It's just a regular secure element. Pretty funny coming from the company that spent the best part of the last 10 years saying how closed source secure elements are a security risk and secure elements are unnecessary, while sweeping under the rug their unfixable seed extraction vulnerability.
They literally had to make compromise, when they realized how hard is to make their own open source secure element, that is coming out in 2 years.
I won't critize Trezor for this new device, it's just refreshed model One, but we already spoke they need to do this long time ago.
Only thing they could add is bigger screen and small camera for airgapp support, but than price would be higher than $79.
Blockstream Jade has all that and costs less
Jade doesn't have secure element, they have centralized server
Someone asked whether the SE is open source or not. The answer was:
Thanks! This is interesting.
I was looking on their website and I couldn't find what SE model they are using.
It was OPTIGA Trust M secure element, and only hardware wallet that is using secure element from this manufacturer is Keevo, that is using Infineon Optiga Trust-P.
I was looking forward to new Trezor models as I've been on the lookout for a new HW but if what you are saying is true, then I have to look elsewhere.
Trezor 3 is much better than ledger and old Trezor One, and maybe you can even buy it locally.
You don't have much options elsewhere for this price
