/*
Scroll gas fees are a combination of "L2 execution fees" (on Scroll) and "L1 security fees" (on Ethereum):

totalFee = (l2GasPrice * l2GasUsed) + l1Fee

Where:
- `l2_gas_price` corresponds to the cost of execution on L2
- `l2_gas_used` corresponds to the amount of gas used on L2
- `l1Fee` corresponds to the data availibity and validity proof costs on L1

/*
Fees are calculated as follows (https://community.optimism.io/docs/developers/l2/new-fees.html):

Total transaction fee is a combination of an "L2 execution fee" and an "L1 security fee":

total_fee = (l2_gas_price * l2_gas_used) + (l1_gas_price * l1_gas_used)

Where:
- `l2_gas_price` corresponds to the cost of execution on L2
- `l2_gas_used` corresponds to the amount of gas used on L2
