What Are Common Questions About Hardhat?

Hardhat is a development-environment for Ethereum that allows developers to compile, test, debug and deploy smart-contracts. It comes with a local-Ethereum-network (Hardhat-Network), for fast testing, a built-in-Solidity-compiler, a testing-framework and a plugin-system. Developers control their entire development-workflow via command-line-commands.

Hardhat makes use of JavaScript / TypeScript and has a rich-plugin-ecosystem as well as a local network, making it the ideal choice for teams who prefer to work with JavaScript-tooling. Foundry makes use of Rust for faster compilation and testing but has a higher learning curve. Hardhat is particularly well-suited for working on complex projects where a high degree of customization is needed.

Yes, Hardhat is entirely free and open-source under the MIT license. There are no paid versions or subscription-based versions. The entire ecosystem, including all plugins, is community-driven.

Hardhat supports any EVM-compatible chain, such as Ethereum, Arbitrum, Optimism, Base, and Polygon. Hardhat simulates chain-specific behavior through its configuration and plugins. The local Hardhat Network simulates main-net behavior for testing.

Hardhat has two options to deploy your smart contract: Hardhat Ignition (a declarative deployment system), or custom JavaScript code. In addition to deploying in parallel, if there are errors during deployment, you can recover from them. Your deployed smart contract will also be verifiable on explorers like Etherscan.

Yes, but you should have some knowledge of JavaScript and how to use a terminal. The quickstart option will create a fully functional project structure for you automatically. There is comprehensive documentation available, as well as a VS Code plugin that will allow Ethereum beginners to quickly get started using Hardhat.

Hardhat supports Solidity unit tests, including fuzzing. It also provides end-to-end testing in TypeScript. Additionally, Hardhat allows you to test your smart contracts in a simulated environment called Hardhat Network. When running your tests, Hardhat will provide you with the ability to see the Solidity stack trace of where your contract failed. If your contract fails at runtime, Hardhat will provide you with an auto-generated error message. Hardhat will also report back to you the amount of gas used when you run your tests.

One of the limitations of Hardhat is that it depends on JavaScript and therefore is slower than Foundry's Rust-based solution. Also, while you can easily manage many plugins with Hardhat, large projects can require a lot of work to manage. Because there isn't a built-in way to monitor your deployed smart contract(s) on the mainnet (you would have to use an external service for this), you wouldn't want to use Hardhat to deploy your smart contract to the mainnet unless you had already tested it extensively.

Is Hardhat Worth It?

Hardhat is the top-of-the-line Ethereum development environment, providing mature support for both professional development teams and individuals, all thanks to its robust ecosystem and flexibility. Hardhat's JavaScript native design, extensive library of plugins and the fact that it includes a local network to develop your smart contracts in, make it perfect for developing smart contracts for production purposes. As an open source platform led by Nomic Foundation, Hardhat is one of the most reliable solutions for EVM based smart contract development.

Recommended For

  • All types of Ethereum and EVM developers (from beginner to advanced)
  • Production smart contract development teams
  • JavaScript/TypeScript developers looking to enter the world of Web3
  • Teams working on complex DApps and require custom tooling
  • Multi-chain development teams

!
Use With Caution

  • Rust developers who prefer the speed of Foundry

What Are the Best Alternatives to Hardhat?

  • •
    Foundry: A Rust-based toolkit for developing Ethereum applications that can perform faster compilations and testing. Best suited for development environments where performance is critical, however, has a steeper learning curve and a smaller ecosystem. Recommended for developers who use Rust or those that are looking to develop at high speeds. (getfoundry.sh)
  • •
    Remix IDE: A browser-based Integrated Development Environment (IDE) for rapid prototyping and learning. Does not require a local setup, however, does not have a lot of the advanced testing options nor a plugin ecosystem. Recommended for beginner users and those writing simple smart contracts. (remix.ethereum.org)
  • •
    Truffle Suite: Legacy Ethereum framework that provides migrations and integrates with Drizzle. Provides a more opinionated experience than Hardhat and takes longer to develop. Recommended for teams who already have existing Truffle project(s). (trufflesuite.com)
  • •
    Ape Framework: Python-based Ethereum framework which focuses on testing and coverage. Smaller community, however, has many Python developers. Recommended for data scientists creating on-chain analytical tools. (ape.dev)
  • •
    Brownie: A lightweight Python Ethereum framework that focuses on testing and scripting. Has been discontinued, however, still functions. Alternative for Python developers who want to avoid using JavaScript. (github.com/eth-brownie/brownie)
