     Henceforth, the user is charged the full $\texttt{SignedGasPrice}$, so the Executor will execute the transaction using it, concluding the sequencing process.

 3. In the previous case, it was necessary to compute a more precise effective gas price based on the accurate amount of gas, denoted as $\texttt{GasUsedNew}$, obtained during the transaction’s execution using the correct state root at the time of sequencing transactions (which was not known earlier for straightforward reasons).
