About Gas Fees
Gas fees fluctuate based on network congestion. Use block explorers like https://etherscan.io to check real-time gas prices. During peak times, gas prices can be 10-100x higher than average. Consider using Layer 2 networks (Arbitrum, Optimism, Base) for significantly lower fees.
Understanding Gas Fees
Gas Price (Gwei)
The price you're willing to pay per unit of gas, measured in Gwei (1 Gwei = 0.000000001 ETH). Higher gas prices mean faster confirmation. Check current prices on block explorers.
Gas Limit
The maximum gas a transaction can use. Simple ETH transfers need 21,000 gas, while complex DeFi interactions can require 300,000+. Unused gas is refunded.
Layer 2 Savings
L2 networks like Arbitrum, Optimism, and Base offer 10-100x lower fees than Ethereum mainnet. Use this calculator to compare costs across networks before choosing where to transact.
