You need to install a wallet to interact with blockchain applications. Currently, we support [MetaMask](https://metamask.io/download.html) wallet.

Go ahead and install MetaMask wallet. After a successful installation, you will see a 'fox' like icon at the upper right corner of your browser. 

Click the 'fox' like icon and follow the instructions to create your asymmetric keys(public key and private key).
