Security Enhancement in DeFi Transactions - The industry is exploring mechanisms to protect users from malicious sandwich attacks by validators in decentralized finance (DeFi) transactions [1] - A novel approach involves enabling transactions to react dynamically to potentially malicious validators, rather than simply reverting [1][2] - The proposed solution adjusts transaction slippage (potentially to 0% or a fraction of the original x%) when a malicious validator is detected [2] Technical Implementation - The solution uses on-chain logic to determine validator status, as the exact validator is unknown at transaction creation [2] - The program accesses the current slot to identify potentially malicious validators, using a compact representation (14 bytes, reducible) [2][3] - The list of malicious validators and their upcoming slots can be sourced from an API or user-provided data [3] Usage and Integration - The solution can be implemented as a simple instruction, integrated with routers like Jupiter v6 to dynamically override slippage, or called directly via CPI from other programs [3] - The prototype is experimental and not deployed on-chain, feedback and contributions are welcome [4]
