BTCPay Server

Docker Automated build Deploy to Azure CircleCI

BTCPay Server

Introduction

BTCPay Server is a free and open-source cryptocurrency payment processor which allows you to receive payments in Bitcoin and altcoins directly, with no fees, transaction cost or a middleman.

BTCPay is a non-custodial invoicing system which eliminates the involvement of a third-party. Payments with BTCPay go directly to your wallet, which increases the privacy and security. Your private keys are never uploaded to the server. There is no address re-use, since each invoice generates a new address deriving from your xpubkey.

The software is built in C# and conforms to the invoice API of BitPay. It allows for your website to be easily migrated from BitPay and configured as a self-hosted payment processor.

You can run BTCPay as a self-hosted solution on your own server, or use a third-party host.

The self-hosted solution allows you not only to attach an unlimited number of stores and use the Lightning Network but also become the payment processor for others.

Thanks to the apps built on top of it, you can use BTCPay to receive donations, start a crowdfunding campaign or have an in-store Point of Sale.

How to build

While the documentation advises to use docker-compose, you may want to build BTCPay yourself.

First install .NET Core SDK v2.1.9 as specified by Microsoft website.

On Powershell:

.\build.ps1

On linux:

./build.sh

How to run

Use the run scripts to run BTCPayServer, this example shows how to print the available command line arguments of BTCPayServer.

On Powershell:

.\run.ps1 --help

On linux:

./run.sh --help

How to debug

If you want to debug, use Visual Studio Code or Visual Studio 2017.

You need to run the development time docker-compose as described in the test guide.

You can then run the debugger by using the Launch Profile Docker-Regtest on either Visual Studio Code or Visual Studio 2017.

If you need to debug ledger wallet interaction, install the development time certificate with:

# Install development time certificate in the trust store
dotnet dev-certs https --trust

Then use the Docker-Regtest-https debug profile.
