Hardhat

Foundry is a fast, portable Rust toolchain for Ethereum smart contract engineering that manages dependencies, compiles Solidity, runs fuzz and unit tests, deploys contracts, and drives scripted chain interaction from the terminal or Solidity automation scripts.

Kurtosis packages reproducible multi-service devnets so you can spin up realistic Ethereum or rollup stacks for integration tests faster than hand-maintained compose files.

CreateX is pcaversaccio's trustless universal deployer that wraps CREATE, CREATE2, and CREATE3-style flows so teams can launch contracts from predictable addresses without bespoke factory code.

A hardhat plugin that provides gas usage analytics for smart contract test suites. It has dedicated support for OPStack chains, is a dependency in > 150k Github repos and is downloaded from NPM > 100k per week.

Hardhat plugin to deploy your smart contracts across multiple EVM chains with the same deterministic address. A total of 133 EVM chains are currently supported, including (almost) all OP-stack-powered chains.

A tool to get the most recent deployment from a given environment in foundry. This way, you can do scripting off previous deployments in solidity.
