What You Will Learn
The fundamental innovation of Ethereum as a programmable general-purpose blockchain
How smart contracts execute automatically and the 'code is law' immutability paradox
The architectural layers of DeFi and core financial primitives like DEXs and lending pools
Mechanics of collateralisation, liquidations, impermanent loss, and yield APY sources
Web3 digital ownership, wallet-based identity, and standardisation patterns
How DAOs govern, allocate treasuries, distribute voting weight, and their core limitations
A comprehensive audit of DeFi security vulnerabilities, oracle attacks, and economic death spirals
About This Course
Ethereum, DeFi & Web3 introduces you to the programmable future of finance and decentralized organizations. We move beyond simple asset transfers to study the self-executing agreements that power a multi-billion dollar decentralized economy.
You will learn how Solidity smart contracts execute, how Aave manages collateralized lending without credit checks, how Uniswap executes swaps peer-to-peer using mathematical formulas, how wallets form your portable identity across the web, and how security exploits like reentrancy and oracle attacks threaten the ecosystem.
