ArgsNewSmartContractProcessor defines the arguments needed for new smart contract processor

type SCQueryService 

type SCQueryService struct {
	// contains filtered or unexported fields
}

SCQueryService can execute Get functions over SC to fetch stored values

func NewSCQueryService 

func NewSCQueryService(
	args ArgsNewSCQueryService,
