Smart Contract Exploit

Definition ∞ A smart contract exploit is a security vulnerability within a self-executing contract that is intentionally leveraged by malicious actors. This exploitation typically results in the unauthorized transfer of funds or manipulation of contract logic. Such events occur due to coding errors, design flaws, or unforeseen interactions between contract components. Identifying and mitigating these vulnerabilities is a critical aspect of decentralized application development.
Context ∞ Smart contract exploits represent a persistent and significant risk within the decentralized finance (DeFi) sector, frequently dominating headlines. Current discussions often revolve around the methods used by attackers, the scale of financial losses incurred, and the subsequent impact on project credibility and user trust. Developers and auditors are continually refining their methodologies for code analysis and risk assessment to prevent future incidents.
