func (Keeper) Logger ¶

func (k Keeper) Logger(ctx sdk.Context) log.Logger

Logger returns a module-specific logger.

func (Keeper) OnAcknowledgementPacket ¶

func (k Keeper) OnAcknowledgementPacket(ctx sdk.Context, packet channeltypes.Packet, data types.FungibleTokenPacketData, ack channeltypes.Acknowledgement) error

OnAcknowledgementPacket responds to the the success or failure of a packet acknowledgement written on the receiving chain. If the acknowledgement was a success then nothing occurs. If the acknowledgement failed, then the sender is refunded their tokens using the refundPacketToken function.

func (Keeper) OnRecvPacket ¶

func (k Keeper) OnRecvPacket(ctx sdk.Context, packet channeltypes.Packet, data types.FungibleTokenPacketData) error

OnRecvPacket processes a cross chain fungible token transfer. If the sender chain is the source of minted tokens then vouchers will be minted and sent to the receiving address. Otherwise if the sender chain is sending back tokens this chain originally transferred to it, the tokens are unescrowed and sent to the receiving address.

func (Keeper) OnTimeoutPacket ¶

func (k Keeper) OnTimeoutPacket(ctx sdk.Context, packet channeltypes.Packet, data types.FungibleTokenPacketData) error

OnTimeoutPacket refunds the sender since the original packet sent was never received and has been timed out.

func (Keeper) SendPacket ¶

func (k Keeper) SendPacket(ctx sdk.Context, channelCap *capabilitytypes.Capability, packet exported.PacketI) error

SendPacket implements the ICS4Wrapper interface from the transfer module. It calls the underlying SendPacket function directly to move down the middleware stack. Without SendPacket, this module would be skipped, when sending packages from the transferKeeper to core IBC.

func (Keeper) SendTransfer ¶

func (k Keeper) SendTransfer(
	ctx sdk.Context,
	sourcePort,
	sourceChannel string,
	token sdk.Coin,
	sender sdk.AccAddress,
	receiver string,
	timeoutHeight clienttypes.Height,
	timeoutTimestamp uint64,
	router string,
	fee sdk.Coin,
	memo string,
) error

func (Keeper) SetErc20Keeper ¶

func (k Keeper) SetErc20Keeper(erc20Keeper types.Erc20Keeper) Keeper

func (Keeper) SetRefundHook ¶

func (k Keeper) SetRefundHook(hook types.RefundHook) Keeper

func (Keeper) SetRouter ¶

func (k Keeper) SetRouter(rtr fxtypes.Router) Keeper

SetRouter sets the Router in IBC Transfer Keeper and seals it. The method panics if there is an existing router that's already sealed.

func (Keeper) Transfer ¶

func (k Keeper) Transfer(goCtx context.Context, msg *types.MsgTransfer) (*transfertypes.MsgTransferResponse, error)

Transfer defines a rpc handler method for MsgTransfer.

func (Keeper) WriteAcknowledgement ¶

func (k Keeper) WriteAcknowledgement(ctx sdk.Context, channelCap *capabilitytypes.Capability, packet exported.PacketI, ack exported.Acknowledgement) error

WriteAcknowledgement implements the ICS4Wrapper interface from the transfer module. It calls the underlying WriteAcknowledgement function directly to move down the middleware stack.
