This protocol proposes a novel method to mitigate Sandwich Attacks in DeFi using Uniswap V4's action hooks. By detecting potential malicious transactions at the contract layer, the protocol secures trades and improves fairness of DEXs.
This project addresses the pressing issue of Maximal Extractable Value (MEV) and its specific manifestation in the form of Sandwich Attacks within the Decentralized Finance (DeFi) ecosystem. Leveraging the features introduced in Uniswap V4, particularly the usage of action hooks, we propose a novel protocol solution aimed at mitigating these attacks. The methodology involves the detection of potentially malicious transactions at the contract layer and places them in an intermediate state, pending further analysis. Our solution seeks to balance heightened security measures with user experience. Empirical data support the urgency and feasibility of implementing this protocol to protect users from financial losses and ensure a fair and secure trading environment.
Smart Contracts: Written in Solidity for Ethereum blockchain. Foundry: Framework for smart contract development Uniswap V4 SDK: To leverage action hooks and other protocol features. Flashbots: For MEV-related operations. OpenZeppelin Defender: For monitoring and automated responses. Web3.js: For interacting with Ethereum nodes. JavaScript/React: For the frontend to visualize and interact with the protocol.
