Live Ethereum gas prices — updated every 30 seconds.
This tool shows the current cost of transacting on Ethereum, expressed as gas prices in gwei. It helps users decide when to send transactions or interact with contracts by revealing how expensive network activity is at the moment.
Gas prices reflect demand for block space and are typically shown in gwei, with the fee you pay depending on how much gas your transaction consumes multiplied by the price per unit. When the network is busy, gas prices rise, and a simple transfer costs less gas than a complex smart-contract interaction.
Gas is the unit that measures the computational work a transaction requires on Ethereum. You pay a fee equal to the gas your transaction uses multiplied by the price per unit of gas, which compensates validators for processing it.
Gas prices are driven by demand for limited block space, so they rise when many people transact at once and fall when the network is quiet. Fees can vary significantly within a single day depending on activity.
Transacting when the network is less congested generally means a lower gas price, and simpler transactions consume less gas than complex contract calls. Some users also set a lower priority fee when they are not in a hurry for confirmation.
