You can restrict which cryptocurrencies and networks customers can pay with to fulfill your [payment requests](/payment-requests).

By default, all [supported currencies and networks](/supported-currencies) are available. Whenever CryptoProcessing adds support for a new cryptocurrency or network, it becomes available by default for all merchants. To disable a specific cryptocurrency or network, follow the steps below.

These settings affect only the **payment currency**, not the **expected currency**. See [Currency selection](/payment-requests#currency-selection) for more details.

<Steps>
  <Step>
    Go to **Settings → Payment requests**.
  </Step>

  <Step>
    On the **Currencies** tab, click **Manage**.
  </Step>

  <Step>
    In the dialog that appears, enable or disable specific currency-network pairs by clicking on network names next to the currencies. Search by currency ISO or network name if necessary.

    Disabling a currency-network pair means that the customer will not be able to pay in this specific currency over this network. Disabling all networks for a currency means the currency will not be available for the customer at all. Make sure at least one currency-network pair stays selected, i.e. at least one network is allowed for at least one currency.
  </Step>

  <Step>
    Enter your 2FA code and click **Save changes**.

    The updated settings take effect immediately and affect all new payment requests you create — both [via merchant dashboard](/payment-requests/create-a-payment-request) and [via API](/api-reference/endpoints/payments). They also apply to any ongoing payment requests for which [currency selection](/payment-requests#currency-selection) hasn't been confirmed yet.
