-  <summary>If I want to unsubscribe my validator from <a href="https://smooth.dappnode.io/">Smooth</a>, when is the best time to do it?</summary>
-    Unsubscribing a validator from <a href="https://smooth.dappnode.io/">Smooth</a> causes it to lose all its pending rewards. Hence, the ideal moment to exit <a href="https://smooth.dappnode.io/">Smooth</a> is just after your last successful block proposal is reflected in Smooth's Smart Contract. A successful block proposal transfers all pending rewards claimable, allowing you to claim them before unsubscribing. This approach minimizes the pending rewards lost when unsubscribing.

   No, <a href="https://smooth.dappnode.io/">Smooth</a> does not take your CL rewards. CL rewards are always sent directly to your withdrawal address. <a href="https://smooth.dappnode.io/">Smooth</a> only takes the execution layer rewards, which are the fees or MEV of the blocks you propose. These are the rewards that are sent to the fee recipient.
