# Frequently asked questions

Gas are the fees used in the Ethereum network to incentivise miners to fulfil your request. To find out more visit Ethereum Gas Explained in Plain English
# What is Gwei (used to denominate gas price)?
Gwei is a denomination of the cryptocurrency ether (ETH), which is used on the Ethereum network.
Gwei is the most commonly used unit of ether because "gas" prices are easily specified in gwei. For example, instead of saying that your gas costs 0.000000001 ether, you can say your gas costs 1 gwei.
# Why does it cost so much to mint?
The Ethereum network is constantly processing transactions based on demand, it naturally has spikes in usage at various times or driven by things happening in the ecosystem, therefore, the price of gas will rise and fall inline with this demand.
The current version of the smart contracts cost 400k gas to mint a new edition. We are working on new smart contracts to improve the efficiency of blockchain interaction.
Today with ETH at approx $1500 and sending a transaction with 50 gwei gas price (about average for Jan. 2021) it costs around $30.
Note: As a consequence the cost of minting a piece of work will also increase if you attempt to mint in a period of intense usage.
If you have been quoted an unusually high price for minting we recommend you hold off and keep checking a gas price checker like this one GAS Now till the price has normailsed. If the average price of gas is above 75 gwei we would recommend waiting till the price drops again. You are also able to send a transaction through at a lower price than the average, though these do take a bit longer than those sent through at higher gas.
