Smart contracts sound futuristic, but they're just code that runs on a distributed computer. What makes them interesting—and tricky—is the constraint environment. Every operation costs gas, code can't be easily updated after deployment, and bugs can drain millions in minutes.
This course teaches Solidity fundamentals through actual contract development. You'll deploy to test networks, interact with contracts using Web3 libraries, and learn to read verified contract code on Etherscan. We focus heavily on common vulnerabilities: reentrancy attacks, integer overflow, and access control failures that have caused real exploits.
The goal isn't to make you a blockchain developer overnight, but to give you enough technical understanding to evaluate projects, understand what smart contracts can and can't do, and recognize red flags in contract code.
