Hardhat Helper

WHAT IT DOES

Hardhat Helper is a developer tool that generates Hardhat configuration files, simulates contract compilation and deployment, and creates custom Hardhat tasks. Select an operation — generate a hardhat.config.js file with network configurations and Solidity version, compile a contract (simulated) with source code, deploy a contract (simulated) to a network, or generate a custom Hardhat task. The tool outputs ready-to-use code snippets that you can copy into your Hardhat project. This is essential for developers setting up Hardhat projects, experimenting with contract deployment, learning Hardhat's configuration structure, or generating boilerplate code.

HOW TO USE

Connect your wallet using the BGWallet bridge (MetaMask or any Web3 wallet). Select the operation: "Generate hardhat.config.js" to create a configuration file with network settings and Solidity version, "Compile contracts (simulated)" to simulate compilation of a contract (provide contract name and source), "Deploy contracts (simulated)" to simulate deployment (returns a contract address), or "Generate custom task" to create a new Hardhat task. Fill in the relevant fields — for configuration, select the network and enter the Solidity version; for compile/deploy, enter the contract name and source code; for tasks, enter the task name and description. Click "Generate / Run" to produce the output. Results display the operation name, status, and the generated code or simulation output in a code preview box. You can copy the output directly into your Hardhat project.

TECHNICAL MECHANISM

The tool generates Hardhat configuration and task files using templates. For configuration, it constructs a module.exports object with solidity version, network configurations (including URLs and account settings), and Etherscan API key placeholder. The network is selected from a dropdown (localhost, Sepolia, Goerli, Mainnet fork). For compilation and deployment, the tool simulates the process — it validates the contract source, extracts the contract name, and generates a simulated output with a successful compilation message or a random deployment address. For custom tasks, it generates a task definition file with the task name, description, and a placeholder function body. The tool does not actually compile or deploy contracts — it provides the output in a format that can be copied and used in a real Hardhat project. All operations are performed client-side — no data is stored or transmitted.

WHAT IT CANNOT SEE

The tool cannot actually compile or deploy contracts without a local Hardhat installation — the compilation and deployment are simulated. It cannot read or modify hardhat.config.js files directly — you must copy the generated output manually. It cannot run real Hardhat tasks or scripts — the generated tasks are templates. It cannot generate test reports or coverage reports — the tool does not run tests. It cannot interact with Hardhat's console or debugging tools — it only generates configuration and code. It cannot validate the correctness of Solidity source code — the simulation assumes the source is valid. It cannot deploy to real networks without a private key and RPC configuration. The tool is read-only and does not sign any transactions.

PLEASE NOTE

This tool works exclusively with EVM-compatible chains for the wallet connection, but the Hardhat outputs are chain-agnostic and work with any Hardhat project. Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported for wallet connection but the outputs work for EVM development. The tool provides simulations and templates — for real development, use Hardhat locally. The tool does not store any data — all operations are performed client-side. The tool is provided as-is with no warranty or liability. Always verify generated configurations before using them in production projects.
