Types

type IBCModule

type IBCModule struct {
	porttypes.IBCModule
	// contains filtered or unexported fields
}

IBCModule implements the ICS26 callbacks for the transfer middleware

func NewIBCModule

func NewIBCModule(
	app porttypes.IBCModule,
	bankKeeper types.BankKeeper,
	transferKeeper types.TransferKeeper,
	hubKeeper types.HubKeeper,
	hooks types.MultiDenomMetadataHooks,
) IBCModule

NewIBCModule creates a new IBCModule given the keepers and underlying application

func (IBCModule) OnAcknowledgementPacket

func (im IBCModule) OnAcknowledgementPacket(
	ctx sdk.Context,
	packet channeltypes.Packet,
	acknowledgement []byte,
	relayer sdk.AccAddress,
) error

OnAcknowledgementPacket adds the token metadata to the hub if it doesn't exist

func (IBCModule) OnRecvPacket

func (im IBCModule) OnRecvPacket(
	ctx sdk.Context,
	packet channeltypes.Packet,
	relayer sdk.AccAddress,
) exported.Acknowledgement

OnRecvPacket registers the denom metadata if it does not exist. It will intercept an incoming packet and check if the denom metadata exists. If it does not, it will register the denom metadata. The handler will expect a 'denom_metadata' object in the memo field of the packet. If the memo is not an object, or does not contain the metadata, it moves on to the next handler.

type ICS4Wrapper

type ICS4Wrapper struct {
	porttypes.ICS4Wrapper
	// contains filtered or unexported fields
}

ICS4Wrapper intercepts outgoing IBC packets and adds token metadata to the memo if the hub doesn't have it. This is a solution for adding token metadata to fungible tokens transferred over IBC, in case the Hub doesn't have the token metadata for the token being transferred.

func NewICS4Wrapper

func NewICS4Wrapper(
	ics porttypes.ICS4Wrapper,
	hubKeeper types.HubKeeper,
	bankKeeper types.BankKeeper,
	getState func(ctx sdk.Context) hgtypes.State,
) *ICS4Wrapper

NewICS4Wrapper creates a new ICS4Wrapper.

func (*ICS4Wrapper) SendPacket

func (m *ICS4Wrapper) SendPacket(
	ctx sdk.Context,
	chanCap *capabilitytypes.Capability,
	destinationPort string, destinationChannel string,
	timeoutHeight clienttypes.Height,
	timeoutTimestamp uint64,
	data []byte,
) (sequence uint64, err error)

SendPacket wraps IBC ChannelKeeper's SendPacket function
