Sandwich Attack Resistance refers to a protocol’s ability to prevent a specific type of malicious trading strategy in decentralized exchanges where an attacker places two transactions around a victim’s transaction. The attacker executes a transaction before the victim’s and another immediately after, profiting from the resulting price manipulation. Resistance mechanisms aim to neutralize this exploit, ensuring fair and predictable transaction execution. The goal is to protect users from predatory trading practices.
Context
Sandwich attack resistance is a critical design consideration for decentralized exchange protocols and automated market makers (AMMs) seeking to protect users from Maximal Extractable Value (MEV) exploitation. Developers are exploring various techniques, such as batch auctions, encrypted mempools, and transaction ordering mechanisms, to counter these attacks. The ongoing challenge involves mitigating such exploits without compromising decentralization or efficiency. News frequently covers new protocol upgrades and research aimed at enhancing resistance to these front-running strategies.
