Proprietary might have been the wrong word.
The protocol itself was developed in-house that leverages Superbacked )to encrypt the keys) mixed with the inheritance and legal side of things.
-It doesn't require us to hold any keys
-It's fully non kyc
-Keys are geographically disbursed (nothing at your house)
-No annual fee
Proprietary in the sense that were the only company doing this. Maybe unique would have been a better word!
