# Sandwich Attack Mechanics ⎊ Definition **Published:** 2026-03-13 **Author:** Greeks.live **Categories:** Definition --- ## Sandwich Attack Mechanics Sandwich attack mechanics describe a specific form of MEV where a searcher identifies a large pending trade on a decentralized exchange and places a buy order immediately before it and a sell order immediately after it. The large trade drives the price of the asset up, allowing the attacker to sell their position at a profit while the original trader suffers from increased slippage. This process relies on the transparency of the mempool, where transactions wait to be included in a block. Searchers pay higher gas fees to ensure their transactions are prioritized by validators, effectively "sandwiching" the victim's trade. This activity is a major concern for retail users who face worse execution prices than expected. To combat this, many users are turning to private transaction relays that bypass the public mempool, making it harder for sandwich bots to detect and front-run their trades. - [Slippage Tolerance Settings](https://term.greeks.live/definition/slippage-tolerance-settings/) - [Code Minimization](https://term.greeks.live/definition/code-minimization/) - [Validator Node Hardening](https://term.greeks.live/definition/validator-node-hardening/) - [Side-Channel Attack Protection](https://term.greeks.live/definition/side-channel-attack-protection/) - [Brute Force Attack Resistance](https://term.greeks.live/definition/brute-force-attack-resistance/) - [Electromagnetic Analysis](https://term.greeks.live/definition/electromagnetic-analysis/) - [MEV-Boost Architecture](https://term.greeks.live/definition/mev-boost-architecture/) - [Attack Surface Reduction](https://term.greeks.live/definition/attack-surface-reduction/) ## Glossary ### [Decentralized Governance Models](https://term.greeks.live/area/decentralized-governance-models/) Algorithm ⎊ ⎊ Decentralized governance models, within cryptocurrency and derivatives, increasingly rely on algorithmic mechanisms to automate decision-making processes, reducing reliance on centralized authorities. ### [Gas Price Sensitivity](https://term.greeks.live/area/gas-price-sensitivity/) Price ⎊ Gas price sensitivity, within the context of cryptocurrency options and derivatives, represents the degree to which trading volume and open interest respond to fluctuations in network transaction fees. ### [Liquidity Pool Exploitation](https://term.greeks.live/area/liquidity-pool-exploitation/) Exploit ⎊ Liquidity pool exploitation, within cryptocurrency, options trading, and financial derivatives, represents a class of attacks targeting vulnerabilities in automated market maker (AMM) protocols and related decentralized finance (DeFi) infrastructure. ### [MEV Extraction Techniques](https://term.greeks.live/area/mev-extraction-techniques/) Arbitrage ⎊ MEV extraction techniques frequently leverage arbitrage opportunities across decentralized exchanges (DEXs), capitalizing on temporary price discrepancies for the same asset. ### [Blockchain Forensics](https://term.greeks.live/area/blockchain-forensics/) Analysis ⎊ Blockchain forensics, within the context of cryptocurrency, options trading, and financial derivatives, represents a specialized investigative discipline focused on reconstructing events and identifying actors involved in illicit or anomalous activities. ### [Cryptoeconomic Security](https://term.greeks.live/area/cryptoeconomic-security/) Incentive ⎊ Cryptoeconomic security utilizes economic incentives and penalties to ensure network participants act honestly and maintain protocol integrity. ### [Block Production Incentives](https://term.greeks.live/area/block-production-incentives/) Incentive ⎊ Block production incentives represent the economic mechanisms designed to motivate participants to validate transactions and secure proof-of-stake blockchain networks. ### [On-Chain Analytics](https://term.greeks.live/area/on-chain-analytics/) Analysis ⎊ On-Chain Analytics represents the examination of blockchain data to derive actionable insights regarding network activity, participant behavior, and the underlying economic dynamics of cryptocurrency systems. ### [Systems Risk Assessment](https://term.greeks.live/area/systems-risk-assessment/) Analysis ⎊ ⎊ Systems Risk Assessment, within cryptocurrency, options, and derivatives, represents a structured process for identifying, quantifying, and mitigating potential losses stemming from interconnected system components. ### [Information Transparency](https://term.greeks.live/area/information-transparency/) Context ⎊ Information transparency within cryptocurrency, options trading, and financial derivatives signifies the degree to which pertinent data regarding market participants, order flow, and instrument valuation is readily accessible. ## Discover More ### [Front Running](https://term.greeks.live/definition/front-running-2/) ![A stylized mechanical device with a sharp, pointed front and intricate internal workings in teal and cream.
