The updateGasPriceFromCache method calculates the average gas price based on cached gas prices to update the global gas price used in transaction fees. However, the method incorporates an overly simplistic mean calculation without robust outlier handling or error checks, which could lead to inaccuracies in gas price estimation. An inaccurate gas price can result in either overestimating or underestimating transaction costs, leading to economic losses either by overpaying or by having transactions perpetually stuck due to underpayment.
Code snippet:
Expected Behavior: The gas price calculation should be resistant to potential manipulation by ensuring that outlier values do not skew the average significantly. Implementing a more sophisticated method like the median or trimmed mean could mitigate risks associated with outlier values.
Expected Behavior code snippet:
Logic:
Actual Behavior: The function calculates the mean gas price from cached values directly, without handling outliers or ensuring robust statistical practices. This can lead to incorrect gas price estimations during times of volatile gas price movements or manipulative actions.
