Blockchain DeFi

Build the future of finance. Master Decentralized Finance (DeFi) protocols, liquidity pools, yield farming, and lending smart contracts.

DeFi is rebuilding the banking system without banks. This course explores the architecture of decentralized financial protocols. You will learn to write Solidity smart contracts for ERC-20 tokens, build Automated Market Makers (AMMs) like Uniswap, and create lending/borrowing platforms. We cover Flash Loans, Staking mechanisms, and the security risks unique to DeFi. Perfect for developers wanting to build the next Unicorn protocol on Ethereum.
