Ethereum Tutorial | How to Calculate the Gas Price for an Ethereum Transaction

In this Ethereum tutorial, we'll look at how you check how much gas on Ethereum your smart contract functions are using, and we'll discuss how to estimate how much ETH (or MATIC, AVAX, etc) that your users will have to pay to run the transaction.

This is useful for example to know how much it will cost your users to mint an NFT.

Once you know the gas used, you can get the actual cost by multiplying by the gas price, which is typically presented in GWEI.

This is a great tutorial for beginners to get their heads around the basics of how gas works on Ethereum.
