two-of-three multisignature
wallet · security
A wallet policy where any two of three independent keys can authorize a spend, balancing redundancy and theft resistance.
- Also known as
- 2-of-3 Multisig
1.definition
A 2-of-3 multisig wallet locks funds so any two of three keys must sign a transaction. It is common for shared custody, business treasuries, inheritance planning, and self-custody setups that need recovery options.
2.practice
Good 2-of-3 setups avoid single points of failure by separating seed backups, devices, locations, and roles. Users should also back up the wallet policy or output descriptor, because signatures alone are not enough to reconstruct every wallet.
