What is PayEngine? 🤔

PayEngine is a SaaS platform that enables your application to process payments through the Lightning Network. Our innovation doesn’t lie in simply offering a payment service, but in the flexibility of configuring those payments. Thanks to the granularity of satoshis (sats), we introduce the concept of Pay Rules: conditional payment rules that define exactly when and how money flows.

Real-World Examples 🎯

Imagine a service that unlocks entirely new monetization models:

• 🎶 Per minute spent at a music festival
• 📺 Per second of video streaming (and why not unlock unlimited access once a certain threshold is reached?)
• 🖼️ Per meter walked inside a museum
• 🍺 Per centiliter poured from a beer tap in a bar

With such a system, the possibilities for business model innovation are nearly limitless.

This is what we’re building 🚀

With PayEngine, we’re developing conditional payments with unmatched granularity, designed to be developer-friendly:

• ⚡ Quick and simple integration
• 📦 Multiple SDKs availables
• 🔑 A clear and flexible API

Our field of possibilities begins where traditional solutions stop.

Non-custo is the way but...

As Bitcoiners, we believe in self-sovereignty and non-custodial solutions. But when it comes to building a product that is truly user-friendly and accessible to everyone, a fully non-custodial approach can become a barrier — especially on the Lightning Network.

⚡ That’s why, in order to make PayEngine as accessible as possible, we chose to launch it as a custodial solution.

If custodial services are a no-go for you, we totally understand. But don’t worry: choosing custody first doesn’t mean we won’t add non-custodial support in the future.

👉 Our vision is to let users decide for themselves: custodial or non-custodial.
