What is gas in crypto?
Gas is the fee paid to network validators to process a transaction or smart contract interaction. It's usually measured in gwei, a small fraction of the network's native coin. Gas prices rise and fall with network congestion - the busier the network, the higher the price needed to get a transaction confirmed quickly.
Frequently Asked Questions
Where does this gas price data come from?
It is read directly from public Ethereum, BNB Chain and Polygon nodes using the standard eth_gasPrice call, the same method wallets use internally.
Why is gas higher on Ethereum than on Polygon?
Ethereum mainnet has less transaction throughput and higher demand for block space, so it typically costs more per transaction than newer, higher-throughput chains like Polygon.
How often does this update?
The page refreshes gas prices automatically every 20 seconds.
Does a low gas price guarantee a fast transaction?
No. Gas prices reflect current network demand, and using a price below the current market rate can cause a transaction to sit pending until network activity drops.
Is this gas fee tracker free to use?
Yes, checking live Ethereum, BNB Chain and Polygon gas prices here is free, with no signup and no wallet connection needed.
