A sandwich attack is a form of Miner Extractable Value (MEV) exploitation where an attacker observes a pending transaction in the mempool and places two of their own transactions around it: one immediately before and one immediately after. The front-running transaction drives up the price for the victim’s buy order, and the back-running transaction profits from the victim’s increased price impact. This extracts value from the victim.
Mechanism
Attackers monitor the public mempool for large swap orders on Automated Market Makers (AMMs) that are likely to cause significant price slippage. They then execute a buy order just before the victim’s transaction, and a sell order immediately after, profiting from the price movement induced by the victim. This requires precise timing and control over transaction ordering. It exploits market microstructure.
Mitigation
Mitigation strategies for sandwich attacks include using private transaction relays to hide orders from the public mempool, implementing batch auctions to execute multiple orders at a single price, and designing AMMs with anti-MEV features. These measures aim to reduce the attacker’s ability to manipulate transaction ordering. Strategic protocol design is crucial for fostering a fair and sustainable trading environment, protecting users from predatory practices. This ensures market integrity.
