Functions

func GetInitiator

func GetInitiator(inputData misc.Blob) (string, error)

func GetMesonFees

func GetMesonFees(transfer worker.EthereumApplicationTransfer, inputData misc.Blob) (applications.ApplicationFeeData, error)

GetMesonFees returns meson's LP and Service Fees as reported by the encoded swap TODO does not calculate fluid volume
