Get Started

This guide covers the prerequisites and the basic project wiring for building on Canton with OpenZeppelin's Daml packages.

Prerequisites

• JDK 21: the Daml toolchain runs on Java. Install a recent OpenJDK 21 build and make sure JAVA_HOME points at it.
• DPM (Daml Package Manager): Digital Asset's package manager and SDK installer. Install it from Digital Asset's public installer, then use it to provision the Daml SDK / Canton baseline.
• A Daml project: a directory with a daml.yaml (single package) or a multi-package.yaml (workspace of packages).

Add OpenZeppelin packages

OpenZeppelin's Canton library is distributed as Daml packages. Add the packages you need as dependencies of your Daml project, then build:

# from your project root, with DPM on PATH
dpm build --all

Refer to each component's page for the module path to import and the templates and interfaces it exposes:

• Access Control
• Ownable
• Pausable

• The Settlement (CIP-112) primitive shows how to compose the library into an atomic, value-moving settlement flow.
• The Reference Implementations walk through complete application blueprints built on these pieces.
