New to self-custody so please forgive misunderstandings.
I’m attempting to setup BTC wallets for self-custody and I would love it to attain the next 3 objectives:
(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 towards any pockets software program implementations: no dependence on any pockets or firm in any manner. Can get well pockets purely from phrases.
Up to now the 2 issues I discovered are Multisig wallets or a singlesig + BIP39 passphrase.
Enjoying 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 (beneficial air-gapped cellular pockets for Jade) to create a Multisig pockets from 2 keys I created on the Jade. But it surely 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 specific 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 aim #1. And it would not open in different wallets I attempted, which appears to tie it to Nunchuk (or perhaps a subset of wallets?) and so additionally appears to violate aim #3. Additionally feels uncomfortable to not perceive the totally different features wsh and others in that doc.
The opposite factor I noticed that Jade affords is utilizing an extra BIP39 passphrase (I assume they name it the thirteenth/twenty fifth phrase) on high of the usual restoration phrase. This appears to fulfill #1 and #2 however I do not know if that is commonplace and might be opened with different wallets or one thing bizarre and particular to Jade.
Any suggestions on the best way to setup a pockets that may fulfill these 3 objectives?
