🚀 Master Smart Contract Development in 30 Days! Welcome to the 30 Days of Solidity: The Ultimate Guide to Smart Contract Development (2025) playlist! This comprehensive Solidity tutorial series takes you from zero to hero in smart contract programming, building robust, secure decentralized applications (dApps) on the Ethereum blockchain. Each day, we tackle a new concept or build a practical smart contract, ensuring a hands-on learning experience. What you'll learn: * Solidity Basics: Variables, data types, functions, modifiers, control structures. * Advanced Smart Contracts: DeFi, NFTs, DAOs, Oracles. * Real-World Projects: MiniDex, StableCoin, YieldFarming, NFT Marketplace, Lending Pool, and more! * Ethereum Blockchain Development: Deploy and interact with smart contracts. * Best Practices: Secure coding patterns and common pitfalls. 📚 Complete Video Playlist with Direct Links: • Day 1: https://youtu.be/7AoTBeDrFgk • Day 2: https://youtu.be/jMxpX_OiW4g • Day 3: https://youtu.be/uBre8NtNKxY • Day 4: https://youtu.be/OI9x4G6Tu-k • Day 5: https://youtu.be/MCz9RrQfpj8 • Day 6: https://youtu.be/sxWujOuZRuw • Day 7: https://youtu.be/J0XWaNMFN-c • Day 8: https://youtu.be/zidzGRim__I • Day 9: https://youtu.be/AUA6yZBabJ0 • Day 10: https://youtu.be/QgtW7mwRPC0 • Day 11: https://youtu.be/irc--Pts8zw • Day 12: https://youtu.be/59b60LEo1Lo • Day 13: https://youtu.be/P8qmIlSLOLA • Day 14: https://youtu.be/cqZ9gBj5S-A • Day 14: Part 2: https://youtu.be/vkQkVyF_kJo • Day 15: https://youtu.be/AeVctT0E61s • Day 16: https://youtu.be/3j-SrLl412o • Day 17: https://youtu.be/4AXyPg4GwHU • Day 18: https://youtu.be/FnTUo_WWSTg • Day 19: https://youtu.be/delfyPTbHY8 • Day 20: https://youtu.be/Q9oEHYQGQI4 • Day 21: https://youtu.be/DdvrGf5Rg4Q • Day 22: https://youtu.be/IciiaXNIscg • Day 23: https://youtu.be/lnAFa73apAE • Day 24: https://youtu.be/Ar6AR6I-j-s • Day 25: https://youtu.be/xcaz8XQmtE8 • Day 26: https://youtu.be/kNIzxWTi89g • Day 27: https://youtu.be/Noly0ZUzfeE • Day 28: https://youtu.be/SoWNluca-Bk • Day 29: https://youtu.be/oyitivoEyEg • Day 30: https://youtu.be/mcMp_X1pH4M In this video, we’re building a smart contract called SimpleIOU—a lightweight, peer-to-peer IOU tracker where friends can record debts, pay each other back, and transfer Ether all on-chain. You’ll learn how to: 👥 Register and manage a list of trusted friends 💰 Let users deposit Ether into their account 🧾 Record who owes what to whom with a simple debt ledger 💸 Pay back debt directly using internal balances 📤 Send Ether using both transfer() and call() 🏧 Withdraw funds back to your wallet It’s a great way to practice Solidity concepts like nested mappings, Ether transfers, and balance tracking—while also building something that actually makes sense in the real world. 👨💻 Code from this video: https://builder-hub.notion.site/Simple-IOU-Contract-1ce5720a23ef80acbcb9dda43b5f803f?pvs=4 📚 Join the 30 Days of Solidity Challenge: Build one contract a day and level up your Web3 skills: https://www.web3compass.xyz/challenge-calendar 🔗 Follow Web3 Compass for more Solidity content: 🐦 X (Twitter): https://x.com/the_web3compass 💼 LinkedIn: https://www.linkedin.com/company/the-web3compass 💬 Telegram: https://t.me/+Bmec234RB3M3YTll
