Provides clear, up-to-date guidance and patterns to eliminate confusion and errors when initializing, testing, configuring, and deploying smart contract projects on Hardhat 3, especially for teams migrating from Hardhat 2 or adopting Viem and Ignition workflows.
Create a new Hardhat 3 project configured for ESM with Viem + node:test, add an Ignition deploy module, and run a Solidity and TypeScript test suite on a local edr-simulated network.

Setting up an ESM hardhat.config.ts in Hardhat 3 involves configuring package.json with type module and adjusting tsconfig for node16 compatibility. You must use ESM declarative configuration to correctly initialize your smart contract project.
You run Foundry-compatible Solidity .t.sol tests directly in Hardhat 3 for robust test suites. This workflow supports fuzzing, invariant tests, and event assertions alongside standard TypeScript testing using Viem and node:test.
Hardhat 3 supports running edr-simulated multi-chain local networks for deterministic testing. You can use network.connect usage and extensive vm.* cheatcodes to reliably manage snapshots and forks across these simulated networks.
The best way to deploy with Hardhat Ignition is building declarative Ignition modules to manage deployments and proxies. This approach integrates directly with Hardhat 3 to safely ship contracts and handle secure configVariable management for secrets.
TypeScript test failures with Viem fixtures often stem from incorrect ESM setup or missing node:test integration. Ensure your hardhat.config.ts is properly configured for ESM and that you are using networkHelpers reliably for deterministic simulation.
