I actually put together a service that is focused on this issue called Fidelius Vaults (https://www.fideliusvaults.com). If you have a moment to look, I'd be curious to hear your feedback on whether it solves the problem you stated.
I really like this idea, but what's the longevity of the service? Do you have any sort of contingency plan if you die, or if you don't have the funds to maintain the service anymore?
ah, I dabbled in a same idea, but before "guardians" I had another step, which was contacting the "vault" owner after "keyholder" requests and before "guardians" approval allowing for the owner to veto access if needed be, as another layer of authorization.
glad to see things like these are cropping up, there's a need for sure.
