What Are Gas Fees?
Gas fees are the costs of executing transactions on EVM-compatible blockchains. They are paid to validators/ miners for processing your transaction.
Gwei: The unit used to measure gas price. 1 Gwei = 0.000000001 ETH.
Gas Limit: The maximum gas you're willing to use. More complex operations require more gas.
Tip: Gas prices fluctuate with network demand. Transacting during off-peak hours (weekends, late night UTC) often saves money.

Frequently Asked Questions
What is gas?
Gas is the unit measuring computational effort on Ethereum and EVM-compatible networks. You pay gas fees in the network's native token for each transaction.
Which networks are supported?
The tool supports Ethereum mainnet, Polygon, and BNB Chain with real-time gas data for each.
How accurate are the estimates?
Estimates are based on current network conditions and are updated in real time. Actual costs may vary slightly depending on network congestion.
