Answer 1

You can't include metadata in an additional output of an exchange transaction, unless that transaction has already been balanced. So you have two options here:

1. Add the metadata in the last stage, which balances the exchange. You can use the completerawexchange API to make this easy.
2. If you are using MultiChain 2.0 alpha 2, you can embed metadata within the same transaction output as represents the 'ask' of the change. Something like this:

createrawexchange 7b899fb5050d067bc2fce644dc34bedf9006737779bdb2a37aeb30ae74779127 0 '{"asset1":100,"data":"012345"}'
