Multi-Sig Wallets

Multi-Sig Wallets are cryptocurrency wallets that require more than one private key to authorize a transaction. They are a fundamental security tool for protocols and teams, ensuring that no single person has unilateral control over funds or contract administrative functions.

By setting a threshold, such as three out of five signatures, the wallet prevents theft even if one or two keys are compromised. This is a critical defense against insider threats and phishing attacks.

In the context of DeFi, multi-sigs are often used to manage protocol upgrades and emergency pauses, providing a decentralized layer of trust and accountability for sensitive operations.
