🧑‍💻 Developing

To begin developing locally, visit our local development guide. There are also several video-tutorials:

How to build

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

First, install .NET SDK v8.0 as specified by the Microsoft website.

On Powershell:

.\build.ps1

On linux:

./build.sh

How to run

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

On Powershell:

.\run.ps1 --help

On linux:

./run.sh --help

How to debug

If you want to debug, use Jetbrain's Rider or Visual Studio 2022.

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.

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.

Other dependencies

For more information, see the documentation: How to deploy a BTCPay Server instance.

🧪 API

BTCPay Server has two APIs:

Greenfield API (New)
- Greenfield API documentation
- Greenfield API examples with CURL
Legacy API

The Greenfield API is our brand-new API which is still in development. Once complete, it will allow you to run BTCPay Server headlessly. The Legacy API, is fully compatible with BitPay's API. It has limited features, but allows instant migration from BitPay.
