Gas Front-Running

Gas

⎊ Gas, within cryptocurrency networks like Ethereum, represents the computational effort required to execute specific operations on the blockchain. Front-running, in this context, exploits the transparency of the mempool—the waiting area for unconfirmed transactions—by observing pending transactions and strategically submitting a transaction with a higher gas price to ensure its execution first. This practice allows an actor to profit from anticipated price movements triggered by the observed transaction, effectively capitalizing on information asymmetry and network latency. Consequently, gas front-running introduces a form of market manipulation and can negatively impact user experience through increased transaction costs and potential slippage.
