Definition ∞ Swap data manipulation is the illicit alteration of information related to token exchange transactions. This refers to the deceptive modification of data associated with decentralized exchange (DEX) swap operations. It often involves price feeds, transaction details, or liquidity pool states. Such manipulation can lead to unfair trade execution, front-running, or other exploitative practices. These disadvantage legitimate users.
Context ∞ Swap data manipulation is a serious security concern in decentralized finance, often exploited through flash loan attacks or oracle manipulation. News frequently reports on incidents where attackers exploit these vulnerabilities. This underscores the continuous need for robust oracle security, transparent transaction validation, and comprehensive protocol auditing.
