Ethereum: Smart Contracts in Practice

Intermediate · 5 lessons · 0 complete

A hands-on follow-up to Ethereum Fundamentals that gets you into real Solidity code: the anatomy of a contract, the ERC-20 and ERC-721 token standards, the security patterns every serious contract needs, and how a frontend actually talks to a deployed contract. Built for learners who already understand accounts, gas, and the EVM conceptually and are ready to write and reason about production-grade code.
