Brazil's Pix payment system has rapidly become a dominant payment method since its 2020 launch. It reaches around 76% of the population and handles millions of transactions monthly, making it one of the most widely used payment rails in the country (GFMag (opens new window), BusinessWire (opens new window)).
However, existing Pix infrastructure often relies on intermediaries or centralized systems, which can dilute user sovereignty.
With the DePix Plugin for BTCPay, merchants can accept Pix payments directly - settling to DePix, a BRL-pegged stablecoin on the Liquid Network. This bridges everyday Brazilian commerce with Bitcoin-native infrastructure.
Seamless by design: the plugin adds Pix and DePix as payment methods directly within BTCPay invoices and the Point of Sale. Built on BTCPay Server's plugin architecture (C#), it plugs into the existing UI so you can enable Pix without changing your checkout flow. At checkout, customers see a Pix option and QR; settlement goes to your DePix wallet on Liquid, and payments are tracked natively in BTCPay.

We're excited to witness the launch of the first version of the DePix plugin. It's designed to be genuinely useful for merchants in Brazil, and we hope to see it keep improving as adoption grows.
