What is gas fee ?
Gas is a made up unit used to denote the amount of resources required to do tasks such as installing new smart contracts.
Gas refers to the fee, or pricing value, required to successfully conduct a transaction or execute a contract on the Ethereum blockchain platform. Priced in small fractions of the cryptocurrency ether (ETH), commonly referred to as gwei and sometimes also called nanoeth, the gas is used to allocate resources of the Ethereum virtual machine (EVM) so that decentralized applications such as smart contracts can self-execute in a secured but decentralized fashion.
The exact price of the gas is determined by supply and demand between the network’s miners, who can decline to process a transaction if the gas price does not meet their threshold, and users of the network who seek processing power.
