func GetPrefixedDenom 

func GetPrefixedDenom(portID, channelID, baseDenom string) string

GetPrefixedDenom returns the denomination with the portID and channelID prefixed

func GetTransferCoin 

func GetTransferCoin(portID, channelID, baseDenom string, amount int64) sdk.Coin

func ParamKeyTable 

func ParamKeyTable() paramtypes.KeyTable

ParamKeyTable type declaration for parameters

func ParseHexHash 

func ParseHexHash(hexHash string) (tmbytes.HexBytes, error)

ReceiverChainIsSource returns true if the denomination originally came from the receiving chain and false otherwise.

func RegisterInterfaces 

func RegisterInterfaces(registry codectypes.InterfaceRegistry)

RegisterInterfaces register the ibc transfer module interfaces to protobuf Any.

func RegisterLegacyAminoCodec 

func RegisterLegacyAminoCodec(cdc *codec.LegacyAmino)

RegisterLegacyAminoCodec registers the necessary x/ibc transfer interfaces and concrete types on the provided LegacyAmino codec. These types are used for Amino JSON serialization.

func RegisterMsgServer

func RegisterQueryHandler 

func RegisterQueryHandler(ctx context.Context, mux *runtime.ServeMux, conn *grpc.ClientConn) error

RegisterQueryHandler registers the http handlers for service Query to "mux". The handlers forward requests to the grpc endpoint over "conn".

func RegisterQueryHandlerClient 

func RegisterQueryHandlerClient(ctx context.Context, mux *runtime.ServeMux, client QueryClient) error

RegisterQueryHandlerClient registers the http handlers for service Query to "mux". The handlers forward requests to the grpc endpoint over the given implementation of "QueryClient". Note: the gRPC framework executes interceptors within the gRPC handler. If the passed in "QueryClient" doesn't go through the normal gRPC flow (creating a gRPC client etc.) then it will be up to the passed in "QueryClient" to call the correct interceptors.

func RegisterQueryHandlerFromEndpoint 

func RegisterQueryHandlerFromEndpoint(ctx context.Context, mux *runtime.ServeMux, endpoint string, opts []grpc.DialOption) (err error)

RegisterQueryHandlerFromEndpoint is same as RegisterQueryHandler but automatically dials to "endpoint" and closes the connection when "ctx" gets done.

func RegisterQueryHandlerServer 

func RegisterQueryHandlerServer(ctx context.Context, mux *runtime.ServeMux, server QueryServer) error

RegisterQueryHandlerServer registers the http handlers for service Query to "mux". UnaryRPC :call QueryServer directly. StreamingRPC :currently unsupported pending https://github.com/grpc/grpc-go/issues/906. Note that using this registration option will cause many gRPC library features (such as grpc.SendHeader, etc) to stop working. Consider using RegisterQueryHandlerFromEndpoint instead.

func RegisterQueryServer 

func RegisterQueryServer(s grpc1.Server, srv QueryServer)

func SenderChainIsSource 

func SenderChainIsSource(sourcePort, sourceChannel, denom string) bool

SenderChainIsSource returns false if the denomination originally came from the receiving chain and true otherwise.

func ValidateIBCDenom

ValidateIBCDenom validates that the given denomination is either:

func ValidatePrefixedDenom 

func ValidatePrefixedDenom(denom string) error

ValidatePrefixedDenom checks that the denomination for an IBC fungible token packet denom is correctly prefixed. The function will return no error if the given string follows one of the two formats:

  • Prefixed denomination: '{portIDN}/{channelIDN}/.../{portID0}/{channelID0}/baseDenom'
  • Unprefixed denomination: 'baseDenom'
