If you have a cross-border operation with Brazil and want to use Pix to pay your suppliers, partners or users, you will need a payment service provider. This institution can be a bank, or another authorized entity, such as Payment Institutions.
A payment via Pix will always be made in Brazilian reais (BRL). This means that to generate a Pix payment you must be integrated with institutions that offer Pix payments, such as WEpayments, for example.
It is not possible to link a bank account abroad directly to Pix. However, you can use Pix to make a payment to your Brazilian supplier, partner or user using a specialized solution, such as WEpayments' Payout.
