Knowledge Notes | Gas Fees
① A transaction fee is roughly equal to the amount of Gas used multiplied by the Gas price. Gas prices are usually quoted in Gwei.
② 1 Gwei equals 0.000000001 ETH, or 10 to the power of -9 ETH.
③ Before confirming, check the estimated fee shown in your wallet. If it seems outrageously high, don’t rush to confirm.
