GetAllInterchainAccounts returns a list of all registered interchain account addresses and their associated connection and controller port identifiers

func (Keeper) GetAllPorts 

func (k Keeper) GetAllPorts(ctx sdk.Context) []string

GetAllPorts returns all ports to which the interchain accounts controller module is bound. Used in ExportGenesis

func (Keeper) GetAppVersion 

func (k Keeper) GetAppVersion(ctx sdk.Context, portID, channelID string) (string, bool)

GetAppVersion calls the ICS4Wrapper GetAppVersion function.

func (Keeper) GetInterchainAccountAddress 

func (k Keeper) GetInterchainAccountAddress(ctx sdk.Context, connectionID, portID string) (string, bool)

GetInterchainAccountAddress retrieves the InterchainAccount address from the store associated with the provided connectionID and portID

func (Keeper) GetOpenActiveChannel 

func (k Keeper) GetOpenActiveChannel(ctx sdk.Context, connectionID, portID string) (string, bool)

GetOpenActiveChannel retrieves the active channelID from the store, keyed by the provided connectionID and portID & checks if the channel in question is in state OPEN

func (Keeper) GetParams 

func (k Keeper) GetParams(ctx sdk.Context) types.Params

GetParams returns the total set of the controller submodule parameters.

func (Keeper) InterchainAccount added in v4.1.0 

func (k Keeper) InterchainAccount(goCtx context.Context, req *types.QueryInterchainAccountRequest) (*types.QueryInterchainAccountResponse, error)

InterchainAccount implements the Query/InterchainAccount gRPC method

func (Keeper) IsActiveChannel 

func (k Keeper) IsActiveChannel(ctx sdk.Context, connectionID, portID string) bool

IsActiveChannel returns true if there exists an active channel for the provided connectionID and portID, otherwise false

func (Keeper) IsBound 

func (k Keeper) IsBound(ctx sdk.Context, portID string) bool

IsBound checks if the interchain account controller module is already bound to the desired port

func (Keeper) IsControllerEnabled 

func (k Keeper) IsControllerEnabled(ctx sdk.Context) bool

IsControllerEnabled retrieves the controller enabled boolean from the paramstore. True is returned if the controller submodule is enabled.

func (Keeper) Logger 

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

Logger returns the application logger, scoped to the associated module

func (Keeper) OnChanCloseConfirm 

func (k Keeper) OnChanCloseConfirm(
	ctx sdk.Context,
	portID,
	channelID string,
) error

OnChanCloseConfirm removes the active channel stored in state

func (Keeper) OnChanOpenAck 

func (k Keeper) OnChanOpenAck(
	ctx sdk.Context,
	portID,
	channelID string,
	counterpartyVersion string,
) error

OnChanOpenAck sets the active channel for the interchain account/owner pair and stores the associated interchain account address in state keyed by it's corresponding port identifier

func (Keeper) OnChanOpenInit 

func (k Keeper) OnChanOpenInit(
	ctx sdk.Context,
	order channeltypes.Order,
	connectionHops []string,
	portID string,
	channelID string,
	chanCap *capabilitytypes.Capability,
	counterparty channeltypes.Counterparty,
	version string,
) (string, error)

OnChanOpenInit performs basic validation of channel initialization. The channel order must be ORDERED, the counterparty port identifier must be the host chain representation as defined in the types package, the channel version must be equal to the version in the types package, there must not be an active channel for the specfied port identifier, and the interchain accounts module must be able to claim the channel capability.

func (Keeper) OnTimeoutPacket 

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

OnTimeoutPacket removes the active channel associated with the provided packet, the underlying channel end is closed due to the semantics of ORDERED channels

func (Keeper) Params 

func (k Keeper) Params(c context.Context, _ *types.QueryParamsRequest) (*types.QueryParamsResponse, error)

Params implements the Query/Params gRPC method

func (Keeper) RegisterInterchainAccount 

func (k Keeper) RegisterInterchainAccount(ctx sdk.Context, connectionID, owner, version string) error

RegisterInterchainAccount is the entry point to registering an interchain account: - It generates a new port identifier using the provided owner string, binds to the port identifier and claims the associated capability. - Callers are expected to provide the appropriate application version string. - For example, this could be an ICS27 encoded metadata type or an ICS29 encoded metadata type with a nested application version. - A new MsgChannelOpenInit is routed through the MsgServiceRouter, executing the OnOpenChanInit callback stack as configured. - An error is returned if the port identifier is already in use. Gaining access to interchain accounts whose channels have closed cannot be done with this function. A regular MsgChannelOpenInit must be used.

func (Keeper) SendTx 

func (k Keeper) SendTx(ctx sdk.Context, chanCap *capabilitytypes.Capability, connectionID, portID string, icaPacketData icatypes.InterchainAccountPacketData, timeoutTimestamp uint64) (uint64, error)

SendTx takes pre-built packet data containing messages to be executed on the host chain from an authentication module and attempts to send the packet. The packet sequence for the outgoing packet is returned as a result. If the base application has the capability to send on the provided portID. An appropriate absolute timeoutTimestamp must be provided. If the packet is timed out, the channel will be closed. In the case of channel closure, a new channel may be reopened to reconnect to the host chain.

func (Keeper) SetActiveChannelID 

func (k Keeper) SetActiveChannelID(ctx sdk.Context, connectionID, portID, channelID string)

SetActiveChannelID stores the active channelID, keyed by the provided connectionID and portID

func (Keeper) SetInterchainAccountAddress 

func (k Keeper) SetInterchainAccountAddress(ctx sdk.Context, connectionID, portID, address string)

SetInterchainAccountAddress stores the InterchainAccount address, keyed by the associated connectionID and portID

func (Keeper) SetParams 

func (k Keeper) SetParams(ctx sdk.Context, params types.Params)

SetParams sets the total set of the controller submodule parameters.
