Get Set Up

Clone the project​

git clone https://github.com/openwallet-foundation/multipaz-utopia.git
cd multipaz-utopia

The repository is a Gradle multi-module project. Each organization lives under organizations/ (dmv, bank_of_utopia, registry, upay, brewery), shared issuer code is in shared/, and the deployment/ module knows how to package everything into one container image.

Install a container runtime​

You need either Podman or Docker. Podman is recommended because it's free and requires no license for commercial use. The build automatically detects which one you have installed.

macOS​

# Install Podman
brew install podman

# Podman runs Linux containers in a VM on macOS — initialize it once
podman machine init

# Start the VM (re-run this after each reboot)
podman machine start

Linux​

On Linux, Podman runs natively — no VM required:

# Ubuntu / Debian
sudo apt-get update && sudo apt-get install -y podman

# Fedora
sudo dnf install -y podman
tip

Already have Docker? You can skip Podman entirely — the Gradle build falls back to docker when no podman binary is found.

Verify your toolchain​

java -version       # should report 17 or higher
podman --version    # or: docker --version

With the project cloned and a container runtime ready, you're set to build the bundle in the next step.
