# Become a Validator Once you have configured and launched your node either using the launcher app or using CLI, you'll now have to become a validator to start producing and finalizing the blocks. For this, you'll need to set up a Humanode wallet address (this address will be linked to your validator account and will be used to pay the network fees for authentication and enrollment of your biometrics) and a handheld device. ### Handheld devices for a web app You will need a handheld device (like a phone or tablet) to capture the biometric data. No special configuration is required. * iOS or Android. UPD: iOS 15 is not supported yet. Update in development. * Camera * Accelerometer * Modern Web browsers (Chrome / Firefox / Safari) Move to the next step to set up your substrate address. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
