# Error Shield

When Error Shield Guard is activated, your transaction undergoes a simulation to prevent potential execution errors before it is broadcasted to the network. The purpose of Error Shield is to prevent unnecessary gas expenditure on transactions that are anticipated to fail. Please note that this feature introduces some latency to your trade, as the simulation must be completed before the trade is executed.
