# Address Whitelisting in Casa

## Whitelisting is a security feature that restricts outgoing transactions from your Casa vaults to only addresses you've pre-approved. When enabled, you will not be able to send to any address that isn't saved in your Address Book, giving you an extra layer of protection against unauthorized or accidental transfers.

### How to Enable Whitelisting

1. Log in to your Casa account at [casa.io](https://casa.io/)
2. In the left-hand menu, select **Address Book**
3. At the top of the page, locate the **Whitelisting** toggle (shown as OFF by default)
4. Click the toggle and a confirmation dialog will appear
5. Review the information in the dialog, then click **Enable whitelisting** to confirm

Once enabled, the toggle will display **Whitelisting ON** and a banner will confirm that whitelisting is active across your vaults.

### What Happens When You Enable Whitelisting

- **Takes effect immediately.** The restriction applies to all your vaults as soon as you confirm
- **Existing addresses are automatically whitelisted.** Any addresses already saved in your Address Book will be approved without any additional steps
- **New addresses have a 48-hour waiting period.** Newly added addresses will not be available for transactions until 48 hours after they are added. This is by design, to protect against unauthorized address additions

### Before You Enable Whitelisting

We recommend reviewing your Address Book before turning on this feature to make sure all the addresses you regularly send to are already saved. You can do this directly from the confirmation dialog by clicking **Review Address Book**.

### Managing Whitelisted Addresses

To add a new address to your whitelist:

1. Navigate to **Address Book** in the left-hand menu
2. Click **\+ Add Address** in the top right
3. Add in the address details and save

The new address will be added to your Address Book and will become active after a 48-hour waiting period.

To remove an address from your whitelist, please note that removals are also subject to a 48-hour waiting period before they take effect.

### Turning Off Whitelisting

If you choose to disable whitelisting, please be aware that this change is also subject to a 48-hour waiting period. Whitelisting will remain active and enforced across your vaults until the waiting period has passed.

### Things to Keep in Mind

- Whitelisting applies across **all your vaults**
- You will be **unable to send** to any address not on your whitelist while this feature is active
- Newly added and removed addresses each have a **48-hour waiting period** before changes take effect
- Disabling whitelisting is also subject to a **48-hour waiting period**
- Make sure your Address Book is up to date **before** enabling, to avoid any disruption to planned transactions
