What is gas price gwei?

Gwei is a very small part of the crypto Ether (ETH). It is used to measure the gas price.

Think of "gas" like the fuel your transaction needs to run on the Ethereum network. The gas price is what you pay for each unit of that fuel.

Because the price for one unit is so small, we use Gwei. It is like using cents instead of dollars. So, if the network is busy, the gas price in Gwei goes up. If you want your transaction to be faster, you can choose to pay a higher Gwei price.
