With Hardhat
Hardhat is a development environment to compile, deploy, test, and debug your Ethereum software.
There are a few dependencies to install before we start. Please install the following:
After installing the above dependencies, we can proceed to install hardhat:
npm install --save-dev hardhat
To create your Hardhat project, run this command while you are in the project's root folder:
npx hardhat
Return (choose the most appropriate option):

> Create a basic sample project
Create an advanced sample project
Create an advanced sample project that uses TypeScript
Create an empty hardhat.config.js
Quit
Let’s create the sample project and go through these steps to try out the sample task and compile, test and deploy the sample contract.
The sample project will ask you to install
hardhat-waffle and hardhat-ethers, which makes Hardhat compatible with tests built with Waffle. You can learn more about it in this guide.Hardhat will let you know how, but, in case you missed it, you can install them withnpm install --save-dev @nomiclabs/hardhat-waffle ethereum-waffle chai @nomiclabs/hardhat-ethers ethers
- After setting up your truffle project, be it cloning a repository or initializing a new hardhat project
- Open
hardhat-config.js - Edit
hardhat-config.jswith f(x)Core network credentials - Create a .env file to store your private key of that corresponding wallet address
The files below are just an example, feel free to rename your variables:
.env
FXCORE_WALLET_PRIVATE_KEY=c3b8df3c3165067e05XXXXXXXXXXXXXXXXXXXXXXXXxxxxXXXXXXbb
hardhat.config.js
require("@nomiclabs/hardhat-waffle");
require("dotenv").config();
const fxcorePrivateKey=process.env.FXCORE_WALLET_PRIVATE_KEY
module.exports = {
defaultNetwork: "fxtestnet",
networks: {
hardhat: {
},
fxtestnet: {
url: "https://testnet-fx-json-web3.functionx.io:8545",
accounts: [`0x${fxcorePrivateKey}`]
}
},
solidity: {
version: "0.8.0",
settings: {
optimizer: {
enabled: true,
runs: 200
}
}
},
}
if you have not already installed dontenv, please do so by running the following command:
npm install dotenv
npx hardhat compile
Run this command in root of the project directory:
npx hardhat run scripts/sample-script.js --network fxtestnet
Contract will be deployed on f(x)Core network, it will look something like this:
Greeter deployed to: 0x70A8aa0fb6a0B4732b2daaBc3143E4C3d560DD57
Remember your address would differ, the above is just to provide an idea of structure. Congratulations! You have successfully deployed Greeter Smart Contract. Now you can interact with the Smart Contract.
