The fee for sending transactions on the Ethereum network is known as gas. You should expect to pay a small fee for sending ether tokens, transferring any other ERC-20 compatible cryptocurrency, or running a smart contract on the network.
Gas fees are required for Ether and many other coins and smart contracts that run on the Ethereum network.
Gas prices fluctuate according to market demand and transaction type.
The Ethereum 2.0 upgrade is expected to lower gas prices.
If your gas offer is too low, your transaction may become stuck or remain pending.

In cryptocurrency, gas refers to the fee required to perform transactions or execute smart contracts on blockchain networks, particularly Ethereum. Gas is measured in small units called gwei, a fraction of the cryptocurrency Ether (ETH).

Gas fees compensate network miners or validators for the computational work they perform, ensuring the network remains secure and operational. The amount of gas required depends on the complexity of the transaction. Simple transfers require less gas while executing complex smart contracts or decentralized applications (dApps) demands more.

Gas prices fluctuate based on network demand. During periods of high activity, fees increase. Users can set a gas limit, but if it’s too low, the transaction may fail, wasting the gas already spent.
