Multisig

A multisig (multi-signature) arrangement requires more than one private key to authorise a transaction. A wallet configured as 2-of-3, for example, holds three keys and needs any two to move funds. No single keyholder can act alone, and the loss of one key does not strand the assets.

Why it matters

In estate and succession planning, multisig matters because it separates control from custody. It lets a principal, a fiduciary and a recovery agent each hold a key, so authority can transfer on death or incapacity without any party having unilateral access beforehand. No single custody model is a universal fiduciary requirement.
