Staking / Delegating
You can either delegate your DVPN directly from within the wallet directly or use a 3rd party website that offers more staking options. For example restake.app (which you can interact with through the Keplr wallet as well), offers automatic compounding of your stake.
Do make sure while you are delegating your stake you have carefully selected a validator to trust your stake with. They will never own your stake and you keep being the only one having full control, however it's still important to select a good validator to minimize slashing penalties and support those that bring value to the blockchain and Sentinel overall.
