Frequently Asked Questions
Gas is the fee required to successfully conduct a transaction or execute a contract on the Ethereum blockchain. It's paid in ETH and compensates miners for the computational resources needed to process transactions.
Gwei is a denomination of ETH. 1 Gwei equals 0.000000001 ETH (10^-9 ETH). Gas prices are typically quoted in Gwei because transaction fees are usually very small fractions of ETH.
Gas Limit is the maximum amount of gas you're willing to spend on a transaction. Gas Price is the amount of ETH (in Gwei) you're willing to pay per unit of gas. Total Fee = Gas Limit × Gas Price.
Gas fees fluctuate based on network congestion. During peak times when many users are transacting, fees increase due to competition for block space. During quiet periods, fees decrease.
Simple ETH transfers require 21,000 gas. ERC-20 token transfers need 65,000 gas. Smart contract interactions vary from 100,000 to millions of gas depending on complexity. NFT minting typically requires 200,000-300,000 gas.
