GasDash

GasDash is a zero-backend analytics tool that turns raw Hedera transaction history into an instant cost report. Paste (or auto-fill from WalletConnect) any Hedera account ID and hit Fetch. In 3-5 s the app:

Pulls the last 10 transactions directly from Hedera’s public Mirror Node REST API (no API key).

Sums the network fees, converts them to USD in real-time using the network’s live exchange-rate endpoint.

React 18 + TypeScript template → pulls Mirror-Node REST with native fetch, does the math in a Web Worker, and styles with Material-UI. WalletConnect handles HashPack/MetaMask, exchange-rate endpoint converts ℏ→USD. Entire build was pure vibecoding. Front-end SPA React 18 + TypeScript (Create-React-App) Rapid UI scaffolding; strict types for API data. State / calc React Hooks + a tiny Web Worker Parses JSON, totals tinybars, converts to HBAR/USD, computes latency stats off-thread to keep UI smooth.
