Gas Fees are transaction costs required to perform operations on blockchain networks, particularly on the Ethereum network. These fees compensate miners or validators for the computational energy and resources needed to process and validate transactions or execute smart contracts.
Gas fees are typically measured in Gwei, a denomination of Ether (ETH), where 1 Ether (ETH) = 1,000,000,000 Gwei. The total gas fee for a transaction is calculated by multiplying the Gas Price by the Gas Limit. Gas Price is the amount a user is willing to pay per unit of gas. Gas Limit is the maximum amount of gas a user is willing to consume for their transaction. Gas fees fluctuate based on network demand. They increase during periods of high congestion to reflect the supply and demand for processing power on the network.
