# FalconX and Binance

> Get a Binance sub-account from FalconX, set up Portfolio Margin, one-way mode and cross margin, then create its two API keys and enter them in Blockhouse.

> [!WARNING]
>
> Follow these steps in order. Portfolio Margin must be active before you create the keys: a key created earlier can't get the trading permission it needs.

**1. Get your Binance sub-account**

Ask your FalconX customer success contact to open a sub-account on Binance for this strategy and to give you access to it. Continue below once you have access.

**2. Check Portfolio Margin is on**

In the sub-account, open the **USDⓈ-M** futures page, then the settings icon in the top bar. On the **Features** tab, open **Account Mode**: **Portfolio Margin** should be marked **Current Mode**. If it isn't, ask FalconX to activate it before you create the keys.

**3. Set one-way mode**

On the same page, check the margin badge above the order form reads **Cross**. Then in settings, on the **Features** tab, open **Position Mode** and choose **One-way Mode**.

**4. Create the read-only key**

In Blockhouse, on the **Binance** tab of the Credentials step, choose **Copy** → **Space** on the **Read-only API IPs**.

On Binance, in the sub-account, open the profile menu → **API Management** → **Create API**, choose **System generated** and **Next**, enter a label such as `Blockhouse read-only`, and complete the security verification. Paste the **API Key** and **Secret Key** into **Read-only API Key** and **Read-only API Secret** in Blockhouse straight away: Binance doesn't show the secret in full again.

Then choose **Edit restrictions**: leave only **Enable Reading** ticked, choose **Restrict access to trusted IPs only**, paste the IPs and choose **Confirm**. Choose **Save** and complete the verification again. In Blockhouse, tick **IPs are whitelisted for read-only API**.

**5. Create the trading key**

In Blockhouse, choose **Copy** → **Space** on the **Trading API IPs**, then create a second key on Binance the same way, with a label such as `Blockhouse trading`, and paste it into **Trading API Key** and **Trading API Secret**.

In **Edit restrictions**, choose **Restrict access to trusted IPs only**, paste the IPs and choose **Confirm** first: Binance only allows trading permissions on a key restricted to trusted IPs. Then tick:

* **Enable Spot & Margin & Stock Trading**
* **Enable Portfolio Margin Trading**

Leave every other permission off, including **Enable Margin Loan, Repay & Transfer** and **Permits Universal Transfer**, so your funds stay in your control. Choose **Save**, complete the verification, and in Blockhouse tick **IPs are whitelisted for trading API**.

**6. Finish in Blockhouse**

FalconX needs no account ID per exchange, so there's nothing more to enter on the **Binance** tab.

Check that every key field on the tab is filled in and both IP boxes are ticked. Set up any other exchange from the [FalconX guide](https://docs.blockhouse.app/open-an-account/connect-your-exchanges/prime-brokers/falconx), then [submit the Credentials step](https://docs.blockhouse.app/open-an-account/connect-your-exchanges).
