Extended Parachain Template

Check Build

The Extended Parachain Template is a ready-to-use parachain template, pre-configured with the Assets pallet, a simple Governance system (Collective & Motion pallets), and other useful base features.

This is a solid starting point for most Parachain projects as it is a more feature-rich alternative to the base Substrate Parachain Template (which it is derived from).

This template is maintained by the Delivery Services team at Parity.

🚀 Getting Started

🦀 Rust Setup

First, complete the basic Rust setup instructions.

🔧 Build

Clone the extended parachain template repository:

git clone https://github.com/paritytech/extended-parachain-template

Use the following command to build the node without launching it:

cargo build --release

🕸️ Run a local network

Next you will need a compatible release of Polkadot to run a testnet. You may also want to use Zombienet (available for Linux and MacOS) for spinning up a testnet:

You can find linux and macOS executables of the Zombienet CLI here:

https://github.com/paritytech/zombienet/releases Download the Zombienet CLI according to your operating system.

Tip: If you want the executable to be available system-wide then you can follow these steps (otherwise just download the executable to your working directory):

wget https://github.com/paritytech/zombienet/releases/download/v1.3.30/zombienet-macos
chmod +x zombienet-macos 
cp zombienet-macos /usr/local/bin

Make sure Zombienet CLI is installed correctly:

./zombienet-macos --help

You should see some similar output:

Usage: zombienet [options] [command]

Options:
  -c, --spawn-concurrency <concurrency>  Number of concurrent spawning process to launch, default is 1
  -p, --provider <provider>              Override provider to use (choices: "podman", "kubernetes", "native")
  -m, --monitor                          Start as monitor, do not auto cleanup network
  -h, --help                             display help for command

Commands:
  spawn <networkConfig> [creds]          Spawn the network defined in the config
  test <testFile> [runningNetworkSpec]   Run tests on the network defined
  setup <binaries...>                    Setup is meant for downloading and making dev environment of Zombienet ready
  version                                Prints zombienet version
  help [command]                         display help for command

You may use a reference implementation from the folder zombienet-config or make your own. More instructions here: Simulate parachains in a test network

🏛 Governance

Parachain governance is a very crucial topic that goes beyond using sudo for privileged calls. Read our Governance Explainer here
