Gas fees are the fees charged by Ethereum miners for processing transactions on the Ethereum network. These fees are paid in ether, the native currency of Ethereum.
The gas fee is calculated based on the amount of gas used by a transaction, and the gas price, which is set by the miners. The gas price is usually denominated in Gwei, a unit of ether.
The total gas fee paid by a transaction is the gas used by the transaction multiplied by the gas price.
The purpose of gas fees is to incentivize miners to process transactions on the Ethereum network. By charging these fees, miners are able to earn a reward for their work in processing transactions and maintaining the Ethereum network.
Gas fees are an important part of the Ethereum network, and they help to keep it secure and running smoothly.
