Hi @mrmeansoup, there is no offline wallet for STEEM. Your wallet is contained in your steemit address. Regarding your question about how to transfer STEEM from poloniex, I think this might help. You can find your STEEM address thus. 1. Click on your photo icon 2. Use the drop down button to find 'wallet'. 3. Click on 'wallet' 4. Find 'permissions' on the left side of your PC and click on it. 5. Click on 'active'. 6 . Select and copy the wallet address on 'active' (e.g. STM64ifx...) and paste on poloneix, the field where you should enter your address. I hope this helps you.
