They made a switch even for new Trezor Safe 3 and Trezor Safe 5 that include standard paper backups only for 20 words, that is the new SLIP39 standard.
Even when you add firmware in Trezor Suite for Trezor Safe 3 and 5 you are now getting 20 words as a default option.
Older Trezor Safe 3 had paper backups in package with 12/24 seed words.
I understand now what you are talking about. You are right: The new 20-word backup feature is available on both Trezor Safe models. I just checked the box content of those two models. The Safe 5 is shipped with the 20-word backup cards. However, they don't specify what backup cards are part of the Safe 3 box. It only says "
2x Wallet backup card." It's fair to assume that those are also the 20-word ones.
It's too bad that they removed the traditional 12/24 word backup cards. I am sure that many users still prefer those and both Trezor Safe models support them.
Interesting. Last time I checked, they removed the Trezor T from the hardware wallet section in their shop, but they didn't touch the bundles. I even posted about it in one of the Trezor threads in this sub. It's good that it's back.
I believe it should be 40% instead.
Their Amazon store says 50%. I didn't make any calculations on my own until now. Now that you asked, it's 50%. Old price: $179. New price: $89.40.
