Best bitcoin inheritance services
Six companies offer a structured bitcoin inheritance product, and the biggest structural difference is whether the plan still works if the company is gone. Casa, Bitkey, and Onramp's default processes require the company's servers or staff to be operational when the heir claims; Unchained, AnchorWatch, and Nunchuk's on-chain Miniscript option are designed to execute on the Bitcoin network regardless of company status. Waiting periods also vary widely — from none at Unchained to six months at Casa standard and Bitkey.

About this guide
These comparisons are maintained by Unchained. We have tried to represent every service accurately and fairly, and where another service does something well that Unchained does not, we say so. Unchained appears as the reference point throughout because every page is built around a single question: how does this service differ from Unchained? That framing is why Unchained is more prominently featured, not because we consider it the default right answer for every reader.
