Hi trandongnhat, you have to use Metamask on the Kovan network. To do it:
- Click on the Metamask fox on your browser
- At the top left of the Metamask pop-up, click on "Main Ethereum Network"
- From the menu, choose "Kovan Test Network"
And that's all. Now make sure to read the tutorial to know of to request Kovan Ether and use the platform.
