Hardhat-reef-template

Hardhat-reef-template is used to create a new Hardhat project for the Reef-chain. It includes all the essentials dependencies used to develop Reef contracts.

Installing

Clone template and configure the new project name.

git clone git@github.com:reef-defi/hardhat-reef-template.git project-name

Install all dependencies with yarn.

You are good to go!

Running

Write scripts under the scripts directory and run them using the following run template...

yarn hardhat run scripts/{script-name}.js

The default Greeter contract script can be run using the following command...

yarn hardhat run scripts/sample-script.js

Configure

Define your Reef chain URL in hardhat.config.js (by default ws://127.0.0.1:9944):

Hardhat-reef uses the default network reef. If the user wants to run the script on the other network, he can do so in CLI with --network {network-name} flag.

Example:

yarn hardhat run scripts/sample-script.js --network hardhat

Users can define the network configuration in hardhat.config.js. He can switch the defaultNetwork to the desired one.

Configuring the Reef network, the user can edit its URL. If the URL exists (can be pinged), the system will automatically connect to it, else it will run internal Reef-Node and try to connect to it.

The default configuration has reef defined as the default network, and its URL is set to: ws://127.0.0.1:9944.

module.exports = {
	solidity: "0.7.3",
  defaultNetwork: "reef" // just an example of picking the desired network. This line is not needed!
};

Users can modify their values by replacing the existing ones like so...

module.exports = {
	solidity: "0.7.3",
  networks: {
		reef: {
			url: "ws://127.0.0.1:9944",
		}
	},
};

Connect to the reef-testnet...

module.exports = {
	solidity: "0.7.3",
  networks: {
		reef: {
			url: "wss://rpc-testnet.reefscan.com/ws",
		}
	},
};
