Notes for users

In order to submit a relayer fee for an IBC packet, a MsgPayPacketFee needs to be in the TX before the packet creating msg.

• native ics20 transfer:

transferCoin := sdk.NewCoin(sdk.DefaultBondDenom, sdk.NewInt(1))
ibcPayloadMsg := ibctransfertypes.NewMsgTransfer(path.EndpointA.ChannelConfig.PortID, path.EndpointA.ChannelID, transferCoin, actorChainA.String(), receiver.String(), clienttypes.Height{}, uint64(time.Now().Add(time.Minute).UnixNano()))
ibcPackageFee := ibcfee.NewFee(oneToken, oneToken, sdk.Coins{})
feeMsg := ibcfee.NewMsgPayPacketFee(ibcPackageFee, ibctransfertypes.PortID, path.EndpointA.ChannelID, actorChainA.String(), nil)

_, err = chainA.SendMsgs(feeMsg, ibcPayloadMsg)

• cw20-ics transfer

execMsg := wasmtypes.MsgExecuteContract{
	Sender:   actorChainA.String(),
	Contract: cw20ContractAddr.String(),
	Msg:      exec,
}
ibcPackageFee := ibcfee.NewFee(oneToken, oneToken, sdk.Coins{})
feeMsg := ibcfee.NewMsgPayPacketFee(ibcPackageFee, ibcContractPortID, path.EndpointA.ChannelID, actorChainA.String(), nil)

_, err = chainA.SendMsgs(feeMsg, &execMsg)
