Project Description

FlipFlow is a tiny onchain coin‑flip dapp for Flow EVM Testnet. Connect your wallet, submit a flip transaction, and watch the global flip counter update. Hover over the counter to preview the last five flips, and jump to Flowscan to inspect your latest transaction. The app is a lightweight React + TypeScript frontend with modern wallet UX and zero backend.

How it's Made

React + TypeScript dapp on Flow EVM Testnet. Wagmi + ConnectKit wrap the app for wallet UX; viem handles reads/writes. Public client reads getFlipCount and paged getFlipResults for the hover tooltip; wallet client submits flipCoin, waits for receipt, then refreshes state. HMR boots via frontend.tsx, with a glass UI in index.css. No backend—everything is client‑side. Flowscan links surface the latest tx, and APITester shows simple fetch flows.
