Today I’m going to show you how to build an Ethereum Dapp with React.js! Let’s create a blockchain-based simple application powered by Ethereum smart contracts on the blockchain. I’ll walk you through step-by-step in the process from start to finish.

We’ll create the Ethereum smart contract first, deploy it to the blockchain and connect it with our React app.

Ethereum Smart Contract

When coding the ethereum blockchain, we actually write code, called Smart Contract with Solidity. We program and debug it on our own development environment (a personal blockchain run in local computer). Once it is ready, we deployed it to the public ethereum testnet (there are multiple ones), and finally launch it to the mainnet.

Contract deployment costs ether. We can get ether for free in testnet, but have to pay a small amount of ether (read money) to deploy contracts in the mainnet…
