What You'll Learn

 

➡️ Blockchain & Ethereum Fundamentals:

▸ Understand how Blockchains, from Bitcoin to Ethereum, work.

▸ Master core concepts: cryptographic hashing, consensus (PoW vs. PoS), and the EVM.

▸ Learn to use essential tools like Metamask and Etherscan.

➡️ Solidity: From Zero to Smart Contract Master:

▸ Core Solidity: Master variables, data types, functions, modifiers, and error handling.

▸ Advanced Patterns: Implement inheritance, libraries, and upgradeable contracts (proxies).

▸ Security is Key: Learn to identify and prevent common attacks like re-entrancy, oracle manipulation, and integer overflows.

➡️ Professional Smart Contract Development:

▸ Modern Tooling: Use industry-standard tools like Hardhat and Foundry for professional development workflows.

▸ Testing & Deployment: Write comprehensive unit and integration tests; deploy your contracts to testnets and mainnet.

▸ ERC Standards: Create your own cryptocurrencies (ERC-20) and NFTs (ERC-721/1155).

➡️ Decentralized Finance (DeFi) Deep Dive:

▸ DeFi Primitives: Understand the "money legos"—stablecoins, DAOs, and oracles (like Chainlink).

▸ Building a DEX: Code a complete Automated Market Maker (AMM) like Uniswap from the ground up.

▸ Lending & Borrowing: Engineer a DeFi protocol where users can lend assets and borrow against collateral, like Aave or Compound.
