First you need your Metamask private key. Open Metamask.

Click on the identicon (the icon on the opposite side of the Metamask logo).

Select the account you'd like to export.

On the Account page, click on the menu (three dots) at the upper right corner:

Click on the “Account Details” button.

Click “Export Private Key”:

Enter your password and click “Confirm”

Your private key is revealed. Copy to clipboard.

Now, you need to import your Metamask wallet into your Oasis Chrome extension wallet. Open your Chrome extension wallet.

1. Click on the identicon.
2. Click 'Import' on the bottom of the page.
3. Select 'Ethereum-compatible Private Key'
4. Give your account a name of your choosing. I like 'Emerald paratime account' or something like that.
5. Paste your private key from steps 1-7 above.

Now you can click the identicon on your Oasis wallet to switch back and forth between your Oasis consensus layer account and your Emerald paratime account.

1. Click the identicon and switch to your Oasis consensus layer account.
2. Copy your address to the clipboard.
3. Click the identicon and switch to your Emerald paratime account.
4. Select 'Paratimes', then 'To Consensus' and send your ROSE to the address copied on your clipboard.

Yes, I also hope this process gets easier as development proceeds. Sixteen steps to transfer money is a big impediment to ease-of-use.
