Smart Contract Vulnerabilities

Definition ∞ Smart contract vulnerabilities are flaws or weaknesses in the code of self-executing contracts deployed on a blockchain. These imperfections can be exploited by malicious actors to steal funds, disrupt operations, or manipulate contract outcomes. Identifying and rectifying these vulnerabilities is paramount for the security of decentralized applications and financial protocols.
Context ∞ News concerning smart contract vulnerabilities frequently arises after significant exploits or hacks occur in the decentralized finance (DeFi) sector. These reports highlight the critical importance of rigorous code audits, formal verification, and secure development practices to safeguard the integrity of on-chain applications and user assets.
