101 sats \ 3 replies \ @dtonon 17 Oct 2022 \ on: Which hardware wallets (other than ColdCard) support BIP 85? bitcoin
Interesting feature. Probably useful in a company enviroment or for specific projects.
For personal use I don't know if I want to have an unique master seed and mix all my seeds (real, testing, temporary, etc wallets) under a unique key. Without a note attached to the single seeds could be confusional retriving the correct one only by the index. Ok, you can have an "index - note" list elsewhere :)
Finally you put all the eggs in one basket, if you leak this master seed you are in troubles... But if you need to generate a lot of seeds keeping an offline backup for all of them can actually be a real problem, that BIP85 solves.
Any other useful use of BIP85?

good for uncle jim setups. i have this for two family members who use hardware wallets and will most certainly lose their backup but i don't want their seeds in my possession. i know i could derive them if needed again

You actually own their seeds :)
However your point is clear, managing family group is a use case! Thank you for the feedback.

Yes, you'd need a note to explain the use of the additional generated seeds. But this doesn't have to be encrypted, and could be part of your estate planning.
One seed to rule them all..
