Multi-Sig Wallets

Definition

Multi-sig wallets are cryptocurrency storage solutions requiring multiple distinct private keys to authorize a transaction. This security feature, short for multi-signature, mandates that a predetermined number of signatories must approve a transaction before it can be executed. For instance, a “2-of-3” multi-sig wallet requires two out of three designated keys to sign off on any outgoing transfer. This mechanism significantly reduces the risk of single points of failure, protecting assets against theft, loss of a single key, or unauthorized access, making them a preferred choice for institutional holdings and joint accounts.
