# Manage Polkadot Validators

{% hint style="info" %}
Validators can often vary in the amount of time that they are elected and their performance. These factors ultimately can affect the amount of staking rewards you earn from nominating to them. As such Nova Wallet recommends that you monitor your Validator's performance on a semi-frequent basis.
{% endhint %}

{% hint style="info" %}
Nova Wallet by default will nominate your stake to recommended Validators. These Validators are selected by an algorithm every staking era (24 hours on Polkadot) based on a range of security and profitability criteria. You can manually select Validators if you so desire at any time.
{% endhint %}

You can change the Validators which you stake with at any time:

1. Open the Nova Wallet application.
2. `Select` the **Staking screen**.
3. `Select` your staking position, in this case, would be **Polkadot DOT**.
4. From the Polkadot staking screen `select` **"Your validators"**.
5. From the Your validators screen `select` **Change**.
6. You can now choose to select Nova Wallet's recommended validators, or you can choose to select them by yourself.
7. Once you are happy with your validators `select` **Continue**.
8. Review the contextual information including any associated fees and `select` **Confirm**.
9. Your validators will now be updated in the next staking era.
