BTCPay Server

BTCPay Server is a free, open-source, self-hosted Bitcoin payment processor that allows merchants to accept payments directly to their wallet with zero fees and no intermediaries.

🚀 Overview

BTCPay Server solves the problems of high transaction fees, loss of control over funds, privacy concerns, and censorship risks inherent in third-party cryptocurrency payment processors. It provides a secure, non-custodial way to accept Bitcoin and Lightning Network payments directly into your own wallet.

It's built for merchants, e-commerce store owners, freelancers, non-profits, local businesses, and communities who want full sovereignty over their payment processing without relying on centralized services.

The project was created by the open-source Bitcoin community, starting as an alternative to services like BitPay, to liberate merchants and promote decentralized, censorship-resistant payments. It's maintained by contributors worldwide through the BTCPay Server Foundation.
