The XDN QT Wallet allows users to stake their holdings directly without ever giving up control of your funds.
In order to stake your coins from the QT Wallet you must first encrypt your wallet. You cannot stake from a wallet that is not encrypted.
To get started, simply select "Unlock Wallet..." from the Settings menu. You will then be prompted to enter your wallet passphrase.
IMPORTANT: You must leave your wallet open and "unlocked for staking" in order to actively stake your coins!
