Types ¶

type ICS20Module ¶

type ICS20Module struct {
	porttypes.IBCModule
	// contains filtered or unexported fields
}

ICS20Module implements ibcporttypes.IBCModule for ICS20 transfer middleware. It overwrites OnAcknowledgementPacket and OnTimeoutPacket to revert quota update on acknowledgement error or timeout.

func NewICS20Module ¶

func NewICS20Module(app porttypes.IBCModule, cdc codec.JSONCodec, k quota.KeeperBuilder, l ltypes.MsgServer,
) ICS20Module

NewICS20Module is an IBCMiddlware constructor. `app` must be an ICS20 app.

func (ICS20Module) OnAcknowledgementPacket ¶

func (im ICS20Module) OnAcknowledgementPacket(
	ctx sdk.Context, packet channeltypes.Packet, acknowledgement []byte, relayer sdk.AccAddress,
) error

OnAcknowledgementPacket is called on the packet sender chain, once the receiver acknowledged the packet reception.

func (ICS20Module) OnRecvPacket ¶

func (im ICS20Module) OnRecvPacket(ctx sdk.Context, packet channeltypes.Packet, relayer sdk.AccAddress,
) exported.Acknowledgement

OnRecvPacket is called when a receiver chain receives a packet from SendPacket.

record IBC quota
Try to unpack and prepare memo. If memo has a correct structure, and fallback addr is defined but malformed, we cancel the transfer (otherwise would not be able to use it correctly).
If memo has a correct structure, but memo.messages can't be unpack or don't pass validation, then we continue with the transfer and overwrite the original receiver to fallback_addr if it's defined.
Execute the downstream middleware and the transfer app.
Execute hooks. If hook execution fails, and the fallback_addr is defined, then we revert the transfer (and all related state changes and events) and use send the tokens to the `fallback_addr` instead.

func (ICS20Module) OnTimeoutPacket ¶

func (im ICS20Module) OnTimeoutPacket(ctx sdk.Context, packet channeltypes.Packet, relayer sdk.AccAddress) error

OnTimeoutPacket implements types.Middleware

type ICS4 ¶

type ICS4 struct {
	porttypes.ICS4Wrapper
	// contains filtered or unexported fields
}

ICS4 implements porttypes.ICS4Wrapper (middleware to send packets and acknowledgements) and overwrites SendPacket to check IBC quota.

func NewICS4 ¶

func NewICS4(parent porttypes.ICS4Wrapper, kb quota.KeeperBuilder) ICS4

func (ICS4) SendPacket ¶

func (q ICS4) SendPacket(
	ctx sdk.Context,
	chanCap *capabilitytypes.Capability,
	sourcePort string,
	sourceChannel string,
	timeoutHeight clienttypes.Height,
	timeoutTimestamp uint64,
	data []byte,
) (uint64, error)

SendPacket implements types.Middleware

type MemoHandler ¶ added in v6.4.0

type MemoHandler struct {
	// contains filtered or unexported fields
}
