This repository contains the advanced phase of my 30-day Solidity mastery challenge — Days 21–30.
Focus: Refactor previous projects, write *Foundry tests, deploy smart contracts to *Sepolia Testnet, and verify functionality.
🟢 New to Phase 2?
Phase 2 focuses on testing, deployment, scripting, and production-level best practices.
You’ll see the same projects from Days 1–20, but now refactored, fully tested, and verified.

- 💻 Advanced smart contract refactoring
- 🧪 Full Foundry test suites for all projects
- 🚀 Deployment scripts to Sepolia Testnet
- 📚 Project-specific READMEs with instructions and contract addresses
- Solidity ^0.8.30
- VS Code + Remix IDE
- Git + GitHub (SSH)
- Foundry (forge test / forge script)
- Sepolia Testnet deployment
Phase 2 pushes me from writing contracts to testing, deploying, and verifying production-ready smart contracts.
This is how professional Web3 developers ensure code quality and reliability.
