Hardhat is a comprehensive development environment consisting of different components for editing, compiling, debugging, and deploying your smart contracts.
Requirements
Before you begin, you need to install the following dependencies:
If you are on Windows, we strongly recommend using WSL 2 when following this guide. When deploying to Monad, set evmVersion: "prague" in your Hardhat Solidity compiler settings. For example:solidity: {
version: "0.8.28",
settings: {
evmVersion: "prague",
},
},
1. Create a new Hardhat project
You can use the hardhat-monad template to create a new project with Monad configuration already set up.hardhat-monad is a Hardhat template with Monad configuration. git clone https://github.com/monad-developers/hardhat-monad.git
cd hardhat-monad
2. Install dependencies
3. Create an .env file
Edit the .env file with your private key:PRIVATE_KEY=your_private_key_here
Protect your private key carefully. Never commit it to version control, share it in public repositories, or expose it in client-side code. Your private key provides full access to your funds.
4. Deploy the smart contract
The following commands use Hardhat Ignition:Deploying to the local hardhat node
Run hardhat node by running:To deploy the example contract to the local hardhat node, run the following command in a separate terminal:npx hardhat ignition deploy ignition/modules/Counter.ts
Deploying to Monad Testnet
Ensure your private key is set in the .env file.Deploy the contract to Monad Testnet:npx hardhat ignition deploy ignition/modules/Counter.ts --network monadTestnet
npx hardhat ignition deploy ignition/modules/Counter.ts --network monadTestnet --reset
Deploying to Monad Mainnet
Ensure your private key is set in the .env file.Deploy the contract to Monad Mainnet:npx hardhat ignition deploy ignition/modules/Counter.ts --network monadMainnet
npx hardhat ignition deploy ignition/modules/Counter.ts --network monadMainnet --reset
1. Create a new Hardhat3 project
You can use the hardhat3-monad template to create a new project with Monad configuration already set up for Hardhat3.hardhat3-monad is a Hardhat3 template with Monad configuration.To learn more about Hardhat3, please visit the Getting Started guide. git clone https://github.com/monad-developers/hardhat3-monad.git
cd hardhat3-monad
2. Install dependencies
3. Set up your private key
Create a .env file in the project root:PRIVATE_KEY=your_private_key_here
ETHERSCAN_API_KEY=your_etherscan_api_key_here
Protect your private key carefully. Never commit your .env file or expose your private key. Your private key provides full access to your funds.
4. Deploy the smart contract
The following commands use Hardhat Ignition:Deploying to a local chain
npx hardhat ignition deploy ignition/modules/Counter.ts
Deploying to Monad Testnet
Ensure your .env file is set up with your private key.npx hardhat ignition deploy ignition/modules/Counter.ts --network monadTestnet
Deploying to Monad Mainnet
Ensure your .env file is set up with your private key.npx hardhat ignition deploy ignition/modules/Counter.ts --network monadMainnet
