A gas fee is the payment you make to a blockchain network to process and confirm your transaction, varying with network demand and complexity.
A gas fee is the cost of performing a transaction or running a smart contract on a blockchain. It compensates the validators or miners who process and secure the network.
Fees vary with network congestion. When demand is high, gas fees rise as users compete to have their transactions confirmed sooner. Complex transactions, like interacting with DeFi protocols, cost more than simple transfers.
The term originated with Ethereum, where computational effort is measured in units of "gas," but similar fees exist on most blockchains under different names.
Understanding gas fees helps you avoid overpaying. Many users time transactions for periods of lower congestion or choose lower-fee networks for routine activity.
