Types

type Keeper 

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

Keeper defines the IBC interchain accounts host keeper

func NewKeeper 

func NewKeeper(
	cdc codec.Codec, key storetypes.StoreKey, legacySubspace icatypes.ParamSubspace,
	ics4Wrapper porttypes.ICS4Wrapper, channelKeeper icatypes.ChannelKeeper, portKeeper icatypes.PortKeeper,
	accountKeeper icatypes.AccountKeeper, scopedKeeper exported.ScopedKeeper, msgRouter icatypes.MessageRouter,
	authority string,
) Keeper

NewKeeper creates a new interchain accounts host Keeper instance

func (Keeper) AuthenticateCapability 

func (k Keeper) AuthenticateCapability(ctx sdk.Context, cap *capabilitytypes.Capability, name string) bool

AuthenticateCapability wraps the scopedKeeper's AuthenticateCapability function

func (Keeper) ClaimCapability 

func (k Keeper) ClaimCapability(ctx sdk.Context, cap *capabilitytypes.Capability, name string) error

ClaimCapability wraps the scopedKeeper's ClaimCapability function

func (Keeper) GetActiveChannelID 

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

GetActiveChannelID retrieves the active channelID from the store keyed by the provided connectionID and portID

func (Keeper) GetAllActiveChannels 

func (k Keeper) GetAllActiveChannels(ctx sdk.Context) []genesistypes.ActiveChannel

GetAllActiveChannels returns a list of all active interchain accounts host channels and their associated connection and port identifiers

func (Keeper) GetAllInterchainAccounts 

func (k Keeper) GetAllInterchainAccounts(ctx sdk.Context) []genesistypes.RegisteredInterchainAccount

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

func (Keeper) GetAppVersion 

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

GetAppVersion calls the ICS4Wrapper GetAppVersion function.

func (Keeper) GetAuthority 

func (k Keeper) GetAuthority() string

GetAuthority returns the 27-interchain-accounts host submodule's authority.

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 host submodule parameters.

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) Logger 

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

Logger returns the application logger, scoped to the associated module

func (Keeper) OnChanCloseConfirm 

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

OnChanCloseConfirm removes the active channel stored in state

func (Keeper) OnChanOpenConfirm 

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

OnChanOpenConfirm completes the handshake process by setting the active channel in state on the host chain

func (Keeper) OnChanOpenTry 

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

OnChanOpenTry performs basic validation of the ICA channel and registers a new interchain account (if it doesn't exist). The version returned will include the registered interchain account address.

func (Keeper) OnChanUpgradeTry 

func (k Keeper) OnChanUpgradeTry(ctx sdk.Context, portID, channelID string, proposedOrder channeltypes.Order, proposedConnectionHops []string, counterpartyVersion string) (string, error)

OnChanUpgradeTry performs the upgrade try step of the channel upgrade handshake. The upgrade try callback must verify the proposed changes to the order, connectionHops, and version. Within the version we have the tx type, encoding, interchain account address, host/controller connectionID's and the ICS27 protocol version.

The following may be changed: - tx type (must be supported) - encoding (must be supported) - order

The following may not be changed: - connectionHops (and subsequently host/controller connectionIDs) - interchain account address - ICS27 protocol version

func (Keeper) OnRecvPacket 

func (k Keeper) OnRecvPacket(ctx sdk.Context, packet channeltypes.Packet) ([]byte, error)

OnRecvPacket handles a given interchain accounts packet on a destination host chain. If the transaction is successfully executed, the transaction response bytes will be returned.

func (Keeper) Params 

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

Params implements the Query/Params gRPC method
