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.
Context ∞ Multi-sig wallets are widely recognized as a security best practice in the digital asset space, particularly for managing significant amounts of cryptocurrency held by institutions or decentralized autonomous organizations. News reports often highlight their role in mitigating risks associated with single-party control and enhancing governance. The ongoing development focuses on improving user experience and integrating multi-sig capabilities more seamlessly into various decentralized applications.
