Would you mind sharing the rough estimates of the costs for both of the plans?

We are going with $25/wallet/year for silver plan which includes just PIN recovery and $100/wallet/year for gold plan which includes estate recovery also.

Quote

Am I correct in assuming that there aren't any inactivity checks for nominee #1?

Yes

Quote

^{- Not sure if I'm just being pessimistic, but I do have mixed feelings about the second nominee option.}

You can choose not to have nominee #2. Its optional.

Quote

Does the executor have a similar set of requirements to the nominees?

Its a little different. Unlike the nominee, the helper won't know upfront that he is a helper. It is again optional.

Cypherock Cover, the scheme that makes the simple stuff unfeasibly large and bulky.

Speaking of inheritance itself. Split SEED phrase into SSS blobs using 2 of 3 scheme. Encrypt each blob with your hardware based pgp key (How the setup such keys is described here). Give one of the encrypted blobs and HW security key to your nominee. Include one of the remaining encrypted blobs into you legal will with assigned nominee as the lawful beneficiary under will. Instruct lawyer to hand over this will to nominee after your passing.As simple as that. A simple and reliable inheritance plan that doesn't require Cypherock Cover.

You don't know how difficult that is for 99% of the people to do what you just described. So many ways you can screw things up and prevent the assets from being inheritable. Not to forget how expensive it can be to update this setup over time relative to our solution.

Time is flying and who knows what will happen with Cypherock (and as consequence with all its so called inheritance scheme) let's say in 25 years

Solution I have proposed is in the hands of people rather than of 3rd company .

Besides it is more cost effective. In my estimation it requires 3 flash drives/SDcards ( two of them as a backup just for the case) ~ $8-10 to keep SSS blob and two pgp HW key (again one for backup, ~$60) and of this for all period, let's take 25 years. Your solution for the same period will cost $25 x 25 + cost of hardware (silver plan) or $100 x 25 + cost of hardware (gold plan)

You should add the legal costs to this.

Adding the legal will cost nothing to users who already have their wills. To include into the will just an envelope with SSS blob will cost nothing.

Here you are the cost for hardware needed.

2GB Flash Drive - $5.68 . And you can get even cheaper if buy such things in pack. Just do a search.

Security Key C NFC (for setting up pgp key) - $29.00

Looks much cheaper than your hardware, isn't it.

And besides, no 3^rd party.

Thank you for the above explanations, but I still need clarification about how the executor can help a nominee in the estate recovery process.
^{- Despite not getting the whole picture yet, I think it'd be better to assign someone willing to act as the helper than assigning someone who might end up not helping the nominee at all.}

Think of the executor as someone who has technical know hows but does not have have financial skin in the same. This is could be your family friend. Again it is optional and you can completely choose against nominating someone here.
