From First Contract to Trusted dApp

Blockchain promises trust without a middleman, but the code has to actually earn that trust. This course starts with the fundamentals, then puts you straight into writing your first smart contract in Solidity. You will compile, test and deploy on Ethereum using Hardhat or Foundry, treating every deployment like it's real money, because eventually it will be. Security sits at the center of this course: you will learn to spot reentrancy and integer overflow before an attacker does. You will then build a full dApp with Web3, connecting a frontend to your own deployed contract. Your final project brings it all together, an audited, secured contract, and leads to your certification. Every exercise runs on a live testnet, so mistakes cost nothing except a little gas and a lesson learned, long before real funds are ever on the line. If you want to build applications where the code itself enforces the rules, this is where you start. Let's deploy your first contract.
