🧪 FoundryProject251

A modular smart contract monorepo powered by Foundry, built for testing, experimentation, and learning.
This repo contains multiple self-contained Solidity projects, including zkSync experiments and Chainlink-integrated dApps.

�� Monorepo Structure

foundry-projects/
├── foundry-fund-me-f25/        → Chainlink + Crowdfunding
├── foundry-simple-storage-f23/ → Beginner storage contract
├── foundry-zksync/             → zkSync test suite and experiments
├── .gitignore
└── .env                        (not committed)

Each subproject is independently runnable with its own scripts, tests, and deployments.
