Functions

func GetDenomPrefix 

func GetDenomPrefix(portID, channelID string) string

GetDenomPrefix returns the receiving denomination prefix

func GetEscrowAddress 

func GetEscrowAddress(portID, channelID string) sdk.AccAddress

CONTRACT: this assumes that there's only one bank bridge module that owns the port associated with the channel ID so that the address created is actually unique.

func GetModuleAccountName 

func GetModuleAccountName() string

func RegisterCodec 

func RegisterCodec(cdc *codec.Codec)

RegisterCodec registers the IBC transfer types

func RegisterInterfaces 

func RegisterInterfaces(registry cdctypes.InterfaceRegistry)

RegisterInterfaces register the ibc transfer module interfaces to protobuf Any.
