# How to add an exchange currency pair

Add currency pairs that will be available for exchange in the Back Office and B2CORE UI. You can add currency pairs one by one or add multiple pairs at once.

### How to add a currency pair

To add a currency pair:

{% stepper %}
{% step %}
Navigate to **Currencies** > **Currency pairs**.
{% endstep %}

{% step %}
Click **+Create** in the upper-right page corner.
{% endstep %}

{% step %}
On the **Create currency pair** page, fill in the following fields:

* In the **From currency** dropdown, select a base currency.
* In the **To currency** dropdown, select a quote currency.
* The **Enabled for admin** and **Enabled for client** options are set to **Yes** by default, meaning that the currency pair will be available for exchange in the Back Office and B2CORE UI.
* If you want to make the currency pair unavailable for exchange in the Back Office or B2CORE UI, or both, select **No** for the corresponding option.
* In the **Max amount** field, enter the maximum allowed amount per exchange operation in the currency pair.
* In the **Step** field, the minimum increment by which an amount can be changed at a time.
* In the **Request required** dropdown, select:
  * **Yes** — to create requests for admin approval when clients initiate exchanges in the currency pair in the B2CORE UI. After approval, exchanges are executed using the rates specified in the approved requests.
  * **No** — to execute exchanges in the currency pair without admin approval.
