FAQ

Is the gas widget free?

Yes. The widget and the badge are completely free — no API key, no sign-up, no tracking. The only ask is that you keep the small “EVMgastracker” credit link so your readers can find the data source.

How often does it update?

The gas price refreshes about every 60 seconds. Values are read from each chain’s public RPC and converted to USD using the chain’s own native gas-token price.

Which chains can I embed?

All 56 EVM chains tracked by EVMgastracker — Ethereum, major Layer 2s (Base, Arbitrum, OP, Scroll, Linea…) and EVM L1s (BNB, Avalanche, Polygon…). Pick any chain in the selector above.

Can I put the badge in a GitHub README?

Yes. Copy the Markdown snippet and paste it into your README. The SVG badge updates automatically each time the page is viewed, so it always shows the current gas price.
