## What is a Whitelist ?
A whitelist is a defined list of blockchain addresses. When configuring account rules, this list is often used to restrict the permissible recipients for outgoing fund transfers.
A list can contain up to **300 addresses** .
Whitelists can only be edited in batches of 90 addresses. If you need to create a whitelist with more than 90 addresses, you must add these by batches of 90 addresses maximum at a time.
## Create a Whitelist (Administrator)
### Before you start
Your Personal Security Device must be connected to your computer, switched on, and the Ledger Vault app opened.
### Instructions
{% hint style="success" %}
**Best practice:** Create Whitelists per currency, do not mix addresses from multiple currencies in one Whitelist.
{% endhint %}
1. Click **Whitelist** on the left panel.
2. Click **+ New whitelist** in the top right corner.
3. Enter the **Whitelist name** . The group name must be less than 19 characters long and must not contain special characters.
Whitelist names must be unique. Two whitelists can't have the same name.
4. Select the **Whitelist type** from the drop-down list. Note that Transaction type whitelists can only be used in the context of Transaction rules and Smart Contract whitelists in Smart Contract rules, to avoid errors and enable your organization to better manage and control the use of Transaction and Smart Contract rules.
5. (optional) Enter a **Whitelist description** .
6. Click **Next** .
7. Enter addresses.
1. Select a blockchain from the **Currency** drop-down list.
It's not possible to add ERC20 token addresses.
2. Enter the **Name** of the address. It must be less than 45 characters long and must not contain special characters. Address names must be unique per currency. For example, you can have a Polygon and Ethereum address named *Coinplace*, but two Ethereum addresses can't hold the same name.
3. Enter the public **Address** , then click the **Save** button to add it to the list.
The Solana parent Account address can be provided as a SPL token account address. If so DO specify it is saved as a SPL token Account address.
4. Repeat the above steps for each address you want to add.
8. Click **Next**.
9. Check the details and then click **Create whitelist**.
10. Verify that the information displayed on your device is accurate. If it's not, either try again or contact [Support](https://ledgerhq.atlassian.net/servicedesk/customer/portals) .
11. Tap **Confirm** .
### Approval
A *Create Whitelist* request is submitted to all Administrators for approval.
## What's next?
The Whitelist will be created once the request is approved by the number of Administrators defined in the admin rule. \
Once approved, the Whitelist can be added in accounts' rules. For more information, see [Create an account](/help-center/core/workspace-administration/accounts/create-an-account.md) or [Edit an account](/help-center/core/workspace-administration/accounts/edit-an-account.md).
