Definition ∞ An EVM Security Flaw describes a vulnerability or defect within the Ethereum Virtual Machine or smart contracts executing on it. Such flaws can lead to unintended behavior, asset loss, or system instability. These weaknesses often arise from coding errors, logical oversights, or unexpected interaction patterns. Exploitation of an EVM security flaw can have significant financial repercussions for users and projects.
Context ∞ EVM security flaws remain a persistent concern for developers and users within the Ethereum ecosystem and its compatible chains. Regular security audits, formal verification, and bug bounty programs are standard practices to address these risks. The community continuously works to develop more secure coding standards and analysis tools to reduce the occurrence of such vulnerabilities.
