PR Description
This PR resolves an issue where simulating a legacy transaction in a post-frontier fork environment was impossible. The current logic defaults to using
maxFeePerGasandmaxPriorityFeePerGas, which incorrectly identifies the transaction type as EIP-1559.Changes in
TransactionSimulator:buildTransactionmethod to conditionally setmaxFeePerGasandmaxPriorityFeePerGasonly if they are provided. This ensures proper handling of both legacy transactions and EIP-1559 transactions.Changes in Test Cases:
shouldSimulateLegacyTransactionWhenBaseFeeNotZero, to confirm that the transaction simulator correctly processes legacy transactions when the base fee is not zero.
