Boba Network Transaction Fees

1/*
2Total transaction fee is a combination of an "L2 execution fee" and an "L1 security fee":
3
4total_fee = (l2_gas_price * l2_gas_used) + (l1_gas_price * l1_gas_used)
5
6Where:
7- `l2_gas_price` corresponds to the cost of execution on L2
8- `l2_gas_used` corresponds to the amount of gas used on L2
9- `l1_gas_price` corresponds to the cost of publishing the transaction data on L1
10- `l1_gas_used` corresponds to the amount of transaction data published on L1
