Gas cost refers to the fee required to execute operations on a blockchain, primarily on networks like Ethereum. Each action, whether it’s sending tokens, deploying a smart contract, or performing a transaction, consumes computational resources. These resources are measured in gas.Gas is quantified in units, and each action has a specific gas amount associated with it, depending on its complexity. Users pay for this gas using the native currency of the blockchain, like Ether for Ethereum. The price of gas fluctuates based on network demand, which can lead to higher fees during peak times.The gas fee comprises two components: the gas limit, which is the maximum amount of gas a user is willing to spend on a transaction, and the gas price, which determines how much a user pays per unit of gas. Effective management of gas costs is crucial for users, as it can significantly impact the total expense of executing transactions or contracts.
