-Make sure that your validator have a `0x01` type withdrawal address before exiting your validator or you will lose your funds. In the [consensus explorer](https://gnosischa.in/), if your withdrawal address shows as an address that starts with a `0x00` it means that your withdrawal address needs to be upgraded to a `0x01`, please refer to the guide in the [Gnosis Chain documentation](https://docs.gnosischain.com/node/management/withdrawals#how-to-change-the-withdrawal-credential). If your validator already shows a `0x01` address, you DON'T need to follow these steps.
+It is recommended to update your withdrawal credentials to the `0x01` type before exiting your validator. Updating your withdrawal credentials later, when your node is stopped, is more difficult. To check if you already have updated withdrawal credentials you can check your validators in the [consensus explorer](https://gnosischa.in/), if your withdrawal address shows as an address that starts with a `0x00` it means that your withdrawal address needs to be upgraded to a `0x01`, please refer to the guide in the [Gnosis Chain documentation](https://docs.gnosischain.com/node/management/withdrawals#how-to-change-the-withdrawal-credential). If your validator already shows a `0x01` address, you DON'T need to follow these steps.
