Example
networkFee

systemFee
System fee used for the contract call
Number

outputs
It is possible to add additional asset transfers together with a contract call by attaching additional outputs. This is a JSON object containing "to", "amount" and "assetId" with json types respectively string, number and string. If "to" is a script hash, it will be translated to a valid NEO address
JSON
{ "to": "AKJrLM5Q…​", "amount": 1, "assetId": "602c79718…​" }
