	// DefaultGasMultiplier is how many CosmWasm gas points = 1 Cosmos SDK gas point.
	//
	// CosmWasm gas strategy is documented in https://github.com/CosmWasm/cosmwasm/blob/v1.0.0-beta/docs/GAS.md.
	// Cosmos SDK reference costs can be found here: https://github.com/cosmos/cosmos-sdk/blob/v0.42.10/store/types/gas.go#L198-L209.
	//
	// 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
	// in the 0.16 -> 1.0 upgrade (https://github.com/CosmWasm/cosmwasm/pull/1120).
	//
	// The multiplier deserves more reproducible benchmarking and a strategy that allows easy adjustments.
	// This is tracked in https://github.com/CosmWasm/wasmd/issues/566 and https://github.com/CosmWasm/wasmd/issues/631.
	// Gas adjustments are consensus breaking but may happen in any release marked as consensus breaking.
	// Do not make assumptions on how much gas an operation will consume in places that are hard to adjust,
	// such as hardcoding them in contracts.
	//
	// Please note that all gas prices returned to wasmvm should have this multiplied.

func (Keeper) OnAckPacket 

func (k Keeper) OnAckPacket(

	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

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

	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

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,
) (ibcexported.Acknowledgement, 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 (k Keeper) OnTimeoutPacket(
	ctx sdk.Context,

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)
