Gwei is a denomination of Ether, the cryptocurrency used on the Ethereum network. It is specifically used to calculate gas fees for transactions and smart contract operations. One Gwei equals one billionth of an Ether (0.000000001 ETH). This unit allows users to better understand and manage the costs associated with their Ethereum transactions. When you conduct any operation on the Ethereum blockchain, fees are required, and these are expressed in Gwei. Understanding Gwei is crucial for efficiently managing costs on the Ethereum platform.
