Definition ∞ A code logic vulnerability is a defect in the design or implementation of a smart contract or blockchain protocol’s operational sequence that permits unintended behavior or unauthorized actions. This type of weakness stems from an error in the program’s intended execution flow, rather than a simple syntax mistake. Such flaws can lead to asset theft, protocol manipulation, or system instability.
Context ∞ Code logic vulnerabilities represent a significant security concern in the decentralized application landscape, frequently exploited in high-profile hacks and substantial financial losses. The industry places considerable emphasis on thorough code audits, formal verification, and bug bounty programs to identify and mitigate these critical weaknesses prior to deployment. News reports often detail the consequences of such exploits on specific projects and the broader digital asset market.
