New to self-custody so please forgive misunderstandings.
I’m attempting to setup BTC wallets for self-custody and I would really like it to attain the next 3 targets:
(1) Simplicity of storing keys: full entry to the pockets from simply phrases
(2) No single level of failure (i.e., not only a plain singlesig pockets)
(3) Future-proofed in opposition to any pockets software program implementations: no dependence on any pockets or firm in any means. Can get well pockets purely from phrases.
To this point the 2 issues I discovered are Multisig wallets or a singlesig + BIP39 passphrase.
Taking part in round with multi-sig wallets I discovered that it was a bit awkward to re-access the pockets after creating it. For instance, I used Nunchuk (advisable air-gapped cell pockets for Jade) to create a Multisig pockets from 2 keys I created on the Jade. However it appeared simply understanding the 2 keys xpub’s was not sufficient to re-access the pockets later after eradicating it from Nunchuk. To re-access the pockets I needed to export a file from Nunchuk with some descriptors for the two keys with a selected perform (I attempted to learn the bitcion github doc on this however bought confused: https://github.com/bitcoin/bitcoin/blob/grasp/doc/descriptors.md)
wsh(sortedmulti(2,
[--------/84'/0'/0']xpub-----/**,
[--------/84'/0'/0']xpub-----/**))
/0/*,/1/*
So this appeared to violate purpose #1. And it would not open in different wallets I attempted, which appears to tie it to Nunchuk (or possibly a subset of wallets?) and so additionally appears to violate purpose #3. Additionally feels uncomfortable to not perceive the completely different features wsh and others in that doc.
The opposite factor I noticed that Jade provides is utilizing a further BIP39 passphrase (I suppose they name it the thirteenth/twenty fifth phrase) on high of the usual restoration phrase. This appears to fulfill #1 and #2 however I don’t know if that is normal and might be opened with different wallets or one thing bizarre and particular to Jade.
Any suggestions on methods to setup a pockets that may fulfill these 3 targets?
