Foundry vs Hardhat in 2026: Which Solidity Toolchain Wins? Two toolchains. Same goal: write, test, and deploy Solidity. Different design philosophies, very different best-fits in 2026. I've used both in production across smart-contract audits and protocol work over the last two years. Here's an honest comparison so you don't waste a week picking the wrong default for your team. TL;DR Foundry — best for security work, audits, protocol engineering, and anyone who values speed and Solidity-native t
