Ethereum Gas Tracker Screensaver
The Ethereum Gas Tracker screensaver gauges current Ethereum gas prices across speed tiers, read directly from the chain via a public RPC endpoint — no key and no third-party gas API. It's free, runs in your browser, and ESC exits.
How the Ethereum Gas Tracker screensaver works
The saver queries a public Ethereum RPC endpoint directly for the chain's real current base fee.
A gauge shows the real current gas price in gwei, with slow/standard/fast estimates derived from it.
A small trend line tracks how gas has moved over the last few minutes of real blocks.
Readings refresh every block, roughly every 12 seconds, in real time.
A worked example
During a busy period you'll see the real gwei readout climb sharply — genuine network demand pushing up the price of block space, not a simulated spike.
Settings & tips
- Accent recolours the gauge needle.
- Gas moves fast — refreshing every block keeps it current.
- Reading straight from the chain means no third-party gas API can go stale or rate-limit you.
Frequently asked questions
- Is this from Etherscan?
- No — it reads Ethereum's real base fee directly from the chain via a public RPC node, with no third-party gas API or key involved.
- Is a key needed?
- No. Public Ethereum RPC endpoints are free and key-less for light use.
- How often does gas change?
- Every block — roughly every 12 seconds — tracking real network demand.
- Is it free?
- Yes — free, no download, in your browser.
