Day 10: The Multi-Chain Frontier!🌐 Started the Cross-Chain Rebase Token section 💰 Elastic Supply: Balances that breathe based on interest ⚙️ Chainlink CCIP: The bridge for moving tokens across chains Complexity is high, but the grind continues🚀 #Solidity #DeFi #Web3Dev

Day 9 Success: Invariant Testing & Oracle Security🛡️ ✅Built Handler contracts to bound fuzzer inputs for collateral & minting ✅Implemented OracleLib to protect against stale Chainlink price feeds ✅Stablecoin Engine is tested against volatility #Foundry #DeFi #SmartContracts

Day 9: The Wall is Real. 🧱 Finished the Stablecoin section of #AdvancedFoundry. Honestly? It's a lot. There are moments where the complexity makes you want to back out. The only way is forward. Mastery isn't instant—it’s built through the grind. 🛠️ #Web3Dev #Solidity #Foundry

Day 8: Fuzzing the Stablecoin Engine!💥 Finished the unit tests and now the core logic with Fuzz Testing Goal for the night: Achieve max coverage percentage. I need to find the bugs random inputs uncover Security requires brute force testing🛡️ #Foundry #Solidity #Web3Security

Day 7: Full Stop for Security🛑 Today was 100% dedicated to writing unit tests for the core Stablecoin Engine(DSCEngine) Testing the deposit, mint, and Health Factor logic is non-negotiable. Slow progress is solid progress Security over speed🛡️ #Foundry #Solidity #Web3Security

Liquidation & Audits: Why Web3 is High Stakes🤯 Spent hours on deep-dive research today: Understood the Collateral Ratio & Liquidation (it protects the protocol, not the user) Audits: tiny code bugs lead to multi-million dollar exploits Security is a developer's first job.🚨

Back on the DeFi Grind! Day 6: Engine Fully Coded🛡️ Stablecoin Engine (DSCEngine.sol): Coded the Health Factor logic (math that prevents insolvency) Implemented CEI Pattern and ReentrancyGuard in the deposit flow No shortcuts on security!🚀 #Foundry #DeFi #Solidity #Web3Dev

Day 5: DeFi is Live! 🪙 Building the Decentralized Stablecoin Engine (DSCEngine.sol). Core wins: Overcollateralization (Security backbone). Handler Contracts (Hyper-efficient Fuzz Testing). The financial engineering phase has begun. 🛠️ #Foundry #DeFi #Stablecoins #Web3Dev

Day 4: NFT Done. EVM Unlocked. 🔑 From deploying On-Chain SVGs to the machine level: EVM: Opcodes, Bytecode. Encoding: abi.encode vs. abi.encodePacked. Low-Level Calls: Mastering .call(). Knowing the why is the path to truly secure code. 🧠 #Foundry #EVM #Solidity #Web3Dev

Day 3: NFT Mastery Complete! 🎉 Deployed NFT to testnet (MetaMask verified) Key win: Mastering asset permanence—encoding On-Chain SVGs vs relying on IPFS/Pinata Wrote adeployment script and executed the transaction flow perfectly #Foundry #Solidity #NFTs #OnChainArt #Web3Dev

Day 2 of #AdvancedFoundry: NFT Collection🖼️ The focus was ERC-721 and data security: IPFS: Mastered decentralized metadata storage (tokenURI). Contract, deployment script, and some few tests today Securing the data is the core of NFT mastery #Foundry #Solidity #NFTs #Web3Dev

Day 1 of #AdvancedFoundry: ERC-20 Complete🪙 Key wins: Built a token manually, then leveraged OpenZeppelin. Robust unit testing focus (Forge) and secure deployment scripting Learned the limits of using AI for writing test Next : DeFi protocols.🚀 #Foundry #Solidity #Web3

BIG NEWS: Officially starting Advanced Foundry! 🚀 Finished the Fundamentals, now moving to building full-scale protocols. What's next? DeFi, NFTs, DAOs Upgradeable Contracts Fuzz Testing & Security Deep Dives TheTime to push for mastery. 💡 #Foundry #Solidity #Web3Dev

Final Day: Smart Contract Lottery Project Complete! 🏆 Forked Testing Deployment Scripts (Automated deploy) Cheatcodes (vm.warp/roll) Honestly, advanced concepts need deep revision. Completion ≠ Mastery. That study time starts now #Foundry #Solidity #Web3Dev #SmartContracts

Day 5 not Day4 Hahaha

Day 5

Foundry Day 4: Chainlink & Code Integrity. 🔑 Mastered three essentials: Chainlink VRF: For secure, true randomness. Custom Errors: For gas-efficient error handling. CEI Pattern: Reinforced security against reentrancy. Building robust, fair dApps. 🛡️ #Foundry #Solidity

Foundry Day 4: Security + Efficiency 🛡️ Mastered three tools: Code Coverage: Measured test effectiveness Foundry Chisel: Used the REPL for rapid testing Storage Packing: Optimized gas by correctly ordering state variables Test everything. Save gas🚀 #Foundry #Solidity

Day 3 of the #FoundryRevisionChallenge was all about making the knowledge stick! 🧪 Mastered tests and deployment scripts. Key lesson: You don't truly learn to code until you code.🛡️ The revision pass is where the knowledge actually sticks! 🧠🚀 #Foundry #Solidity #Web3Dev

Back from being sick for Day 2 of the #FoundryRevisionChallenge! Focused on L2 deployment & gas hacks. 🚀 L2 Pro Tip: Deploying to non-EVM L2s (like zkSync) requires the foundry-zksync tool. Use EIP-1559 for predictable transaction costs.🛡️ #Foundry #Solidity #Web3Dev
