Definition ∞ A fee fabrication exploit refers to a malicious act where an attacker manipulates a system to generate or claim illegitimate transaction fees. This exploit often targets vulnerabilities in smart contracts or protocol logic that govern fee distribution. The perpetrator benefits by siphoning off funds intended for legitimate network participants. Such an attack undermines the economic security of a decentralized system.
Context ∞ News reports occasionally detail fee fabrication exploits within decentralized finance protocols, resulting in financial losses for users or the protocol itself. These incidents highlight the necessity for rigorous auditing of smart contract code and economic models. Developers continually work to fortify protocols against such sophisticated forms of financial manipulation.
