About Cosy Eth Gas

Cosy Eth Gas is a lightweight Ethereum gas tracker for Chromium browsers. It shows the current Ethereum mainnet gas price directly on the pinned browser toolbar icon, with a cleaner one-decimal view in the popup. The extension is intentionally minimal: no wallet connection, no content scripts, no page injection, no browsing history access, no analytics, and no tracking. Cosy Eth Gas fetches eth_gasPrice from PublicNode every 30 seconds, with LlamaRPC as a fallback. USD cost estimates use a cached Coinbase ETH/USD spot price that refreshes at most once per hour. Features: • Whole-gwei gas badge in the toolbar • One-decimal gas display in the popup • USD estimates for common Ethereum transaction costs • Nice and Cosy design • No wallet permissions • No page access • No tracking or analytics • Open-source code on GitHub
