# Add/Remove Whitelists

Whitelist on Coinstarter is list of administrator-approved addresses whereby, only these addresses can participate in the presale. The goal of having a whitelist is to protect a presale from bot attacks and having real investors. You can enable/disable the whitelist function when you [create a Launchpad](broken://pages/v4qXBzCoNsdXxvK2TTMe).

When creating the launchpad, at step 2 - Launchpad Info, you can choose to enable/disable whitelist here by toggling the "switch" on “Whitelist” section:
