Stake Tokens

Make sure not to bond all your AVL balance since you will be unable to pay transaction fees from your bonded balance.

Go To Staking Tab

Click on stash as shown in picture

Sign and Submit after entering the details

Submit Session Key

Go to Network → Staking again, Ensure you are on Account actions, and enter session key
