Gwei

Gwei, a denomination of Ether (ETH), is used to measure gas fees for transactions on the Ethereum network. One gwei equals one billion wei, where wei is the smallest unit of Ether. This smaller unit simplifies the calculation and comparison of gas fees, as most transactions require fractions of an Ether.

Using gwei allows users to specify gas prices more accurately and ensures transparent, precise pricing for executing smart contracts and transactions on the Ethereum blockchain.
