Definition ∞ A Multi-Sig Exploit refers to a security breach targeting a multisignature (multi-sig) wallet or smart contract. Multisignature wallets require multiple private keys to authorize a transaction, enhancing security by distributing control. An exploit occurs when an attacker circumvents these security measures, often by compromising a sufficient number of the required signatures or exploiting vulnerabilities in the smart contract logic governing the multi-sig setup.
Context ∞ News regarding Multi-Sig Exploits typically arises from incidents where decentralized finance (DeFi) protocols or institutional digital asset custodians suffer significant fund losses. The discussion often centers on the specific vulnerabilities exploited, such as flawed access control mechanisms or insufficient signature threshold configurations. Future considerations involve the development of more resilient multi-sig designs and rigorous auditing processes for smart contracts that manage pooled assets.
