Gas fee

A gas fee is the cost required to execute a transaction or operation on a blockchain, such as transferring cryptocurrencies, running smart contracts, or interacting with DeFi applications. This fee compensates validators (in Proof of Stake) or miners (in Proof of Work) for processing and confirming transactions. On the Ethereum blockchain, gas fees are paid in Ether (ETH).

The amount of gas fees depends on network congestion—the more users and transactions, the higher the cost. Users can prioritize their transactions by paying a higher fee to speed up processing. The introduction of Ethereum 2.0 and Layer 2 scaling solutions aims to reduce transaction costs and improve network scalability.
