The thing with glacier btw, is I'm not recommending people to use the glacier software necessarily (I've never used the glacier software), just that its a good reference as a guide for tools you know and love already.

The thing about custodians, is that I just don't like my collaborative custodian (because I'll never use full custodian eww) to be a company. I'd rather my collaborative custodian not be a government protected entity, but a real person and preferably, family. That's all, and even then, I'd prefer if those collaborative custodians only really have access to a timelocked key, such as what's provided in liana wallet.

In fact, because glacier does not include timelocks, its an incomplete guide and maybe even outdated?

And obviously descriptor wallets are not as easy to work with as "Just memorizing 12 words (and the wallet and version you generated it from to avoid additional footguns)

Here's a neat tool to help deal with that. I probably wouldn't bother with it until your Bitcoin starts to look more like a retirement account than a savings account tho. https://seedhammer.com/

So in other words, what I prefer as the ultimate solution, is full self custody with keys in multiple locations, which only failing that after a timelock, collaborative custody of keys where multiple people who are not likely to collaborate together, sign a psbt you create from a watch only wallet (to ensure they don't collaborate together).

But ah incorperating timelocks into people's setups and even multi-sig on its own is such a new idea to so many people. I was about to bring pre-signed transaction possibilities into this lol.

Anyway, arman the parman's guide is a little more simple and goes over "levels of custody" rather than "This is how you do it" You know like, imagine sending glacier to a newbie right? https://armantheparman.com/zerotrust/
