    System Fees

    The system fee is calculated by opcodes to be executed by the Neo virtual machine. The 10 GAS free system fee will be cancled in NEO3. The total fee is subject to the quantity and type of instructions in the contract script. The calculation formula is as follows:

    where OpcodeSet is opcode set, OpcodePriceiis the cost of opcode i, niis the execution times of instruction i in the contract script.

    The fee of each interop service and instruction is shown in the table below.
