Ionomy doesn't do cash. It's only an exchange for cryptocurrencies. Essentially, you send your Steem, exchange it for Bitcoin, then exchange your Bitcoin for Hive. Or you can just exchange for Bitcoin and then cash that out somewhere else. I use Shakepay for buying Bitcoin or for cashing out Bitcoin. It works through Interac e-transfers. So you could send the bitcoins from Ionomy to your Shakepay Bitcoin address and then exchange them for CAD, and send to your bank account via e-transfer.

For Hive wallet transactions, I installed Hive Keychain and I also use PeakD (the Hive version of Steempeak) as my Hive blogging interface instead of hive.blog, and it has all the features working, including wallet transactions.
