Definition ∞ A batched swap attack is a malicious exploit targeting decentralized exchanges or protocols that process multiple token exchanges within a single transaction. This attack leverages specific vulnerabilities in how these platforms handle grouped operations, often by manipulating pricing or liquidity across several assets simultaneously. The attacker typically executes a series of coordinated trades to extract value, often at the expense of liquidity providers or other users. Such actions disrupt market fairness and can cause significant financial losses for those involved. It represents a sophisticated form of arbitrage or front-running.
Context ∞ The industry is actively working to implement more robust anti-front-running mechanisms and stricter validation for batched transactions to prevent these exploits. Ongoing research focuses on improving smart contract logic and introducing more transparent transaction ordering protocols. A key discussion point involves the trade-off between transaction efficiency and security in decentralized finance. These efforts aim to fortify the integrity of trading environments against coordinated manipulation.
