Protocol Level Frontrunning

Architecture

Protocol Level Frontrunning, within cryptocurrency and derivatives markets, exploits vulnerabilities inherent in the on-chain execution of transactions. It involves strategically positioning a transaction ahead of a target transaction by observing pending transactions in the mempool and submitting a transaction with a higher gas price to achieve priority inclusion in the next block. This technique is particularly relevant in decentralized exchanges (DEXs) and options protocols where price impact from large orders can be substantial, creating an arbitrage opportunity for the frontrunner. The design of robust protocols must incorporate mechanisms to mitigate this risk, such as transaction ordering fairness and gas price prioritization schemes.
