Hardhat est un environnement de développement pour créer et déployer vos logiciels Ethereum

Foundry est une chaîne d'outils Rust rapide et portable pour l'ingénierie de contrats intelligents Ethereum qui gère les dépendances, compile Solidity, exécute des tests de fuzzing et unitaires, déploie des contrats et pilote l'interaction de chaîne scriptée à partir du terminal ou de scripts d'automatisation Solidity.

PoWFaucet is a modular testnet faucet for EVM chains with anti-abuse methods including a mining puzzle, captcha, IP limits, and Gitcoin Passport, and it backs the Sepolia proof-of-work faucet. Teams running a testnet self-host it to hand out test ETH without giving it all to one address.

hardhat-deploy is a Hardhat plugin for replicable deployments with named accounts, proxies, and diamonds. Builders install it when deployments must be repeatable across networks and track upgradeable contracts.

eth-docker is a Dockerized stack for deploying and managing execution, consensus, and validator clients on mainnet. Node operators use it to run a full node setup from configuration files instead of hand-installed binaries.

The Kurtosis ethereum-package spins up reproducible multi-client Ethereum devnets, including mev-boost and supporting tooling. Builders run it when they need a local network that mirrors a real client mix.
