# Connect Binance Futures to VOOI Ultra

This guide explains how to connect Binance Futures trading to VOOI Ultra.

To trade through VOOI Ultra, you need to create a Binance API key and enable the required trading permissions.

## Before You Start

For the **Binance master account**, make sure that:

* The account is verified and funded
* Additional Verification Method is enabled
* Binance Futures is enabled

If you plan to connect a **sub-account**, also make sure that:

* The sub-account has been created and is accessible from the master account
* **Futures trading is enabled for the sub-account**
* The sub-account is funded

**API key:** The API key must be created for the account or sub-account you will use to trade through VOOI Ultra.

1. Log in to Binance at <https://www.binance.com/>
2. Go to **Account > API Management**.
3. If the **Default Security Controls** checkbox is selected, clear it:

   **By checking this box, all existing API Key(s) on your master account and sub-accounts will be subject to Default Security Controls.**

   Complete Binance security verification if prompted.
4. Click **Create API**.
5. Create a new API key.

   Example name: `VOOI Ultra`
6. Complete Binance security verification.
7. Copy the **API Key** and **Secret Key**.

{% hint style="info" %}
**Important:** Copy the Secret Key when Binance shows it. It may not be available again after the API key is saved.
{% endhint %}

8. After **Default Security Controls** have been cleared and the required Binance security verification has been completed, open the API key permissions and enable:
   1. **Enable Futures**
   2. **Enable Spot & Margin Trading**

{% hint style="info" %}
**Important:** Enable these permissions only after updating the Default Security Controls setting and completing the required verification. If the steps are done in the opposite order, Binance may not apply or save the trading permissions correctly.
{% endhint %}

9. Do not enable:
   1. **Enable Withdrawals**
10. Save the API key settings.

5. For an existing sub-account, check that these features are already enabled.
6. If needed, click the **three-dot menu** next to the sub-account and enable the required options.

## If Permissions Are Not Available

If Binance does not allow trading permissions, follow the security steps shown in Binance.

Depending on the account, Binance may require IP restrictions, a self-generated API key, or changes to Default Security Controls.

If **Enable Futures** is not available, make sure Binance Futures was enabled before the API key was created. If needed, create a new API key after enabling Binance Futures.
