	// The original multiplier of 100 up to CosmWasm 0.16 was based on
	//     "A write at ~3000 gas and ~200us = 10 gas per us (microsecond) cpu/io
	//     Rough timing have 88k gas at 90us, which is equal to 1k sdk gas... (one read)"
	// as well as manual Wasmer benchmarks from 2019. This was then multiplied by 150_000

	// The multiplier deserves more reproducible benchmarking and a strategy that allows easy adjustments.

func (Keeper) OnAckPacket 

func (k Keeper) OnAckPacket(
	ctx sdk.Context,
	contractAddr sdk.AccAddress,
	msg wasmvmtypes.IBCPacketAckMsg,
) error

OnAckPacket calls the contract to handle the "acknowledgement" data which can contain success or failure of a packet acknowledgement written on the receiving chain for example. This is application level data and fully owned by the contract. The use of the standard acknowledgement envelope is recommended: https://github.com/cosmos/ics/tree/master/spec/ics-004-channel-and-packet-semantics#acknowledgement-envelope

On application errors the contract can revert an operation like returning tokens as in ibc-transfer.

For more information see: https://github.com/cosmos/ics/tree/master/spec/ics-004-channel-and-packet-semantics#packet-flow--handling

func (Keeper) OnCloseChannel

	ctx sdk.Context,
	contractAddr sdk.AccAddress,
	msg wasmvmtypes.IBCChannelCloseMsg,
) error

OnCloseChannel calls the contract to let it know the IBC channel is closed. Calling modules MAY atomically execute appropriate application logic in conjunction with calling chanCloseConfirm.

Once closed, channels cannot be reopened and identifiers cannot be reused. Identifier reuse is prevented because we want to prevent potential replay of previously sent packets See https://github.com/cosmos/ics/tree/master/spec/ics-004-channel-and-packet-semantics#channel-lifecycle-management

func (Keeper) OnConnectChannel 

func (k Keeper) OnConnectChannel(
	ctx sdk.Context,
	contractAddr sdk.AccAddress,
	msg wasmvmtypes.IBCChannelConnectMsg,
) error

OnConnectChannel calls the contract to let it know the IBC channel was established. In the IBC protocol this is either the `Channel Open Ack` event on the initiating chain or `Channel Open Confirm` on the counterparty chain.

There is an open issue with the [cosmos-sdk](https://github.com/cosmos/cosmos-sdk/issues/8334) that the counterparty channelID is empty on the initiating chain See https://github.com/cosmos/ics/tree/master/spec/ics-004-channel-and-packet-semantics#channel-lifecycle-management

func (Keeper) OnOpenChannel 

func (k Keeper) OnOpenChannel(
	ctx sdk.Context,
	contractAddr sdk.AccAddress,
	msg wasmvmtypes.IBCChannelOpenMsg,
) (string, error)

OnOpenChannel calls the contract to participate in the IBC channel handshake step. In the IBC protocol this is either the `Channel Open Init` event on the initiating chain or `Channel Open Try` on the counterparty chain. Protocol version and channel ordering should be verified for example. See https://github.com/cosmos/ics/tree/master/spec/ics-004-channel-and-packet-semantics#channel-lifecycle-management

func (Keeper) OnRecvPacket 

func (k Keeper) OnRecvPacket(
	ctx sdk.Context,
	contractAddr sdk.AccAddress,
	msg wasmvmtypes.IBCPacketReceiveMsg,
) ([]byte, error)

OnRecvPacket calls the contract to process the incoming IBC packet. The contract fully owns the data processing and returns the acknowledgement data for the chain level. This allows custom applications and protocols on top of IBC. Although it is recommended to use the standard acknowledgement envelope defined in https://github.com/cosmos/ics/tree/master/spec/ics-004-channel-and-packet-semantics#acknowledgement-envelope

For more information see: https://github.com/cosmos/ics/tree/master/spec/ics-004-channel-and-packet-semantics#packet-flow--handling

func (Keeper) OnTimeoutPacket 

func (k Keeper) OnTimeoutPacket(
	ctx sdk.Context,
	contractAddr sdk.AccAddress,
	msg wasmvmtypes.IBCPacketTimeoutMsg,
) error

OnTimeoutPacket calls the contract to let it know the packet was never received on the destination chain within the timeout boundaries. The contract should handle this on the application level and undo the original operation

QuerySmart queries the smart contract itself.

func (Keeper) SetParams 

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

func (Keeper) Sudo 

func (k Keeper) Sudo(ctx sdk.Context, contractAddress sdk.AccAddress, msg []byte) ([]byte, error)

Sudo allows priviledged access to a contract. This can never be called by an external tx, but only by another native Go module directly, or on-chain governance (if sudo proposals are enabled). Thus, the keeper doesn't place any access controls on it, that is the responsibility or the app developer (who passes the wasm.Keeper in app.go)

type LimitSimulationGasDecorator 

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

LimitSimulationGasDecorator ante decorator to limit gas in simulation calls

func NewLimitSimulationGasDecorator 

func NewLimitSimulationGasDecorator(gasLimit *sdk.Gas) *LimitSimulationGasDecorator

func (LimitSimulationGasDecorator) AnteHandle 

func (d LimitSimulationGasDecorator) AnteHandle(ctx sdk.Context, tx sdk.Tx, simulate bool, next sdk.AnteHandler) (sdk.Context, error)

AnteHandle that limits the maximum gas available in simulations only. A custom max value can be configured and will be applied when set. The value should not exceed the max block gas limit. Different values on nodes are not consensus breaking as they affect only simulations but may have effect on client user experience.

When no custom value is set then the max block gas is used as default limit.
