{% hint style="success" %}
In this example:&#x20;

* a separate wallet is used (not the validator's wallet)
* a separate wallet is attached to the validator and `Environment=VALIDATOR_ADDRESS='<nibivaloper1....>'` is added to the service file&#x20;
* a separate wallet should have coins for commissions&#x20;
* the validator must be in the active set
