Contracts Parachain Template

This is the Pop CLI contracts parachain template.

It is based on the Polkadot SDK and is updated by R0GUE after releases in the main Polkadot SDK monorepo.

• ⏫ This template provides a starting point to build a contracts parachain.

• ☁️ It is based on the Cumulus framework.

• 🔧 Its runtime is configured to support WebAssembly smart contracts and PolkaVM smart contracts.

Template Structure

A Polkadot SDK based project such as this one consists of:

• 💿 Node - the binary application.
• 🧮 Runtime - the core logic of the parachain.

Getting Started

Install Pop CLI - the all-in-one Polkadot development tool:

Detailed installation instructions can be found here.

cargo install --force --locked pop-cli

Start a new parachain project with this template:

pop new parachain

When prompted, select 'Pop' as the template provider and 'Contracts' as the type of parachain.

More info can be found here.

Learn how to run your parachain using the pop up command:

pop up parachain -f ./network.toml

PolkaVM smart contract development:

• To emulate the Ethereum JSON RPC, a proxy server needs to be deployed, allowing users to connect to it instead of directly connecting to the node.
• Modified version of Remix IDE for the PolkaVM smart contract development: https://github.com/paritytech/revive-remix.
