A sandwich attack is a specific type of front-running exploit where an attacker places a buy order immediately before a victim’s transaction and a sell order immediately after. The attacker profits from the price movement caused by the victim’s trade. This exploit is prevalent in decentralized exchanges (DEXs) where transaction ordering is predictable.
Mechanism
The mechanism of a sandwich attack relies on the transparency of the mempool, where pending transactions are visible to all participants. The attacker identifies a large incoming order and uses a higher gas fee to ensure their orders are processed immediately before and after the victim’s transaction. This manipulation extracts value from the victim’s trade.
Protection
Protection against sandwich attacks involves strategies like private transaction relays and order flow auctions. These mechanisms prevent transactions from being broadcast publicly to the mempool, eliminating the attacker’s ability to front-run. Implementing these protections is crucial for ensuring fair execution and maintaining user trust in decentralized platforms.
