what is whbar-unwrapper fr?

WHBAR Unwrapper is a small self-hostable web app for converting WHBAR back into native HBAR on the Hedera network, at a fixed 1:1 rate. WHBAR is a wrapped version of HBAR, and this tool exists to reverse that wrapping so the coins arrive directly in your wallet again. Using it is simple: you connect a Hedera wallet, type in an amount, and approve two transactions. The first grants a smart contract permission to spend exactly that amount of WHBAR, never more. The second calls a function on that same contract, which redeems the WHBAR and sends native HBAR back to your account. Both steps happen through SaucerSwap's publicly documented WhbarHelper contract, though this project itself is not affiliated with SaucerSwap. Wallet connections work through the WalletConnect standard, so wallets like HashPack are supported, and account balances are read from Hedera's public mirror node. The app is built with plain TypeScript and no front end framework, using Vite as the build tool and the official Hedera JavaScript SDK to construct transactions. Styling is handled with a single plain CSS file. Running it locally just takes an npm install and npm run dev, after setting a WalletConnect project ID and choosing mainnet or testnet in a small config block. It can be built into a static site and hosted anywhere, and a Netlify config file is already included for one click deployment there or on similar services. Everything runs entirely in the browser. There is no backend server and no database, so transactions are built and signed locally in the user's own wallet, and private keys never leave it. The README includes a lengthy disclaimer making clear that use is at your own risk, since blockchain transactions cannot be reversed and the authors accept no liability for lost funds. The project is released under the MIT license.
