A malicious contract is a piece of code, often a smart contract on a blockchain, designed with the intent to deceive, defraud, or harm users. These contracts can exploit vulnerabilities in code or user behavior to steal funds, manipulate data, or disrupt network operations. Identifying and avoiding malicious contracts is paramount for the security of participants in the digital asset ecosystem. Understanding the characteristics of such contracts provides crucial context for assessing the risks associated with interacting with decentralized applications.
