Why: The error is caused by a nil pointer dereference in the RefreshGasPrice method of the FeeHistoryEstimator struct. This typically happens when an object or variable that is expected to be initialized is actually nil.

Suggested fix: Ensure that all pointers and objects are properly initialized before they are used. Add nil checks before dereferencing pointers to prevent runtime errors.
