Read Contract Variable — Hardhat Code
Read a public variable from a deployed contract using Hardhat.
async function main() {
const Counter = await ethers.getContractFactory('Counter')
const counter = await Counter.attach('0xYourContractAddress')
const value = await counter.count()
console.log('Counter value:', value)
}
main().catch((error) => { console.error(error); process.exitCode = 1 })Hardhat Language Guide

Primary Use Cases
- ▸Compiling and deploying Solidity smart contracts
- ▸Running local Ethereum test networks
- ▸Automated testing of smart contracts
- ▸Debugging and logging transactions
- ▸Scripted contract interactions and deployments
Notable Features
- ▸Local development network (Hardhat Network)
- ▸Solidity compilation and artifact management
- ▸JavaScript/TypeScript-based scripting
- ▸Plugin system for extended functionality
- ▸Integration with ethers.js, web3.js, and Waffle
Origin & Creator
Hardhat was created by Nomic Labs in 2018 to simplify Ethereum smart contract development and provide a powerful local blockchain testing environment.
Industrial Note
Hardhat is preferred for Ethereum development workflows, CI/CD smart contract testing, automated deployment, and integration with frontends or other tools like ethers.js and web3.js.
