Can you expand on "strict protocols" please?

"strict protocols" refer to our will execution schedule, which ensures that the keys are only accessible after the switch is triggered. Even if someone were to hack the system and access the keys before execution, only the designated beneficiaries would have the ability to decrypt the data.

What exactly is preventing someone with the key decrypting the data before some other code in your system runs?

Where an how is user data stored? Do you use cloud providers/SaaS and in which jurisdiction? Considering legal requests for user data are being served, location/jurisdiction for both CipherWill and its servers are important and I don't seem to find this mentioned. Aside, but I don't think I'm alone in considering this a non-starter combined with the whole stack including the client being closed-source. Fresh advertis…

You didn't address the main question:

Sheesh; no excuse not to back up your BIP-39 mnemonic phrases using SLIP-39 (Shamir secret sharing): https://slip39.com/app

Furthermore, you can use the same App to SLIP-39 any arbitrary 128-, 256- or 512-bit key in a way that your family can combine their data to recover.

I can't remember why I didn't pursue this, something about the hardware wallets having a way to do the Shamir upfront? In a different way than just sharing the words. Such that each person winds up with 24 words rather than a subset.

Anyway, I decided I didn't want to migrate my wallet, so I'll look into this. Arbitrary key support is also interesting. Thanks for the tip!

Yes, there are hardware wallets that support SLIP-39 natively; however, the sequence of derived wallets is different than that produced when you take the same seed and save it as a BIP-39 and derive the wallets from the BIP-39 mnemonics.

Using the app, we actually produce the SLIP-39 recovery mnemonics from the underlying BIP-39 seed, and since we can recover the underlying seed, we can regenerate the BIP-39 mnemonics, and import that into a standard hardware wallet.

You’re in the fun phase of designing the tech, but that’s not where the problem lies. I don’t trust you at all. You can tell me about the system you’ve designed, but I only have your word that it really works that way. Trust is 90% of your problem, and the tech is only 10%. I can’t think of anything you could write that would change that. I guess I have to trust my bank with my safe deposit box, but there I see keys, sign in sheets, staff that I recognize that are watching each other enter the vault, etc. How will a website mimic that?

I completely understand — building trust is key, and we’re working on adding transparency through decentralization and exploring open-sourcing to give users more control over their data.

All data is stored in the encrypted form in frankfurt as the cloud provider is from EU. We also use vercel to deliver client code.

Only the people who you've added in your beneficiaries can decrypt the data if Cipherwill is hacked.

How will you prove the decentralization is real and not some BS written by a scammer? How will you prove your app matches the open source to someone that can’t compile it themselves?
