An arbitrage sandwich attack is a predatory trading strategy where a malicious actor identifies a pending transaction in the mempool and executes two transactions around it. The attacker places a buy order immediately before the target transaction and a sell order immediately after, effectively “sandwiching” the user’s trade. This tactic exploits the price slippage caused by the original transaction, allowing the attacker to profit from the price difference. The attack relies on manipulating the order of transactions within a block to extract value from legitimate trades.
Consequence
The primary consequence for the victim is significant price slippage, resulting in a less favorable execution price than initially intended. This extraction of value from legitimate trades reduces overall market efficiency and creates a negative user experience on decentralized exchanges. The profitability of these attacks incentivizes searchers to compete for block space, driving up gas fees for all network participants.
Mitigation
Countermeasures against sandwich attacks include implementing private transaction relays, which prevent transactions from being broadcast to the public mempool where searchers operate. Protocols like SUAVE aim to create a more equitable distribution of MEV by allowing users to express their preferences for transaction ordering. Additionally, some decentralized exchanges utilize anti-MEV mechanisms to automatically detect and prevent such predatory trading strategies.
