It is non-custodial, meaning funds go directly to the merchant’s wallet, offering immediate access and control. The software is free and can be self-hosted or shared, making it accessible for beginners and small businesses. It integrates with major e-commerce platforms and supports the Lightning Network for fast, low-cost transactions. BTCPay Server includes tools for invoicing, point-of-sale, tipping, and crowdfunding, with strong security features like hardware wallet support. It is designed for global use, supporting multiple languages and offering APIs for automation and migration from other payment processors. The project is community-driven, with a permissive MIT license ensuring it remains open and free. This model could revolutionize global commerce by making payment processing more accessible and inclusive.
