" summary

Live demo builds a tiny Solidity contract, compiles bytecode, and successfully deploy to Rinkeby via an HD wallet provider, printing the deployed address. Uses Remix + JavaScript VM for local testing, then wires the real contract to a React frontend using MetaMask + web3 provider (stealing injected provider). Shows read and write calls, transaction confirmations, and the UI state updates after real network transactions, so the example actually works end to end.
