A fungible object or unit is one that is interchangeable - like a penny, for example. Like with ETH transactions, NFT transactions also require gas fees. While this prevents attacks on the network, it does mean that not paying enough gas for a transaction can result in financial losses. If there is not enough gas available to make a transaction, the user still pays for the work that has been done even if a transaction fails. Without a gas cost, a user could - in theory - execute a program that never ends, either intentionally or accidentally, which would bring the entire Ethereum network to a standstill. So, if the minimum amount of gas required to process a standard transaction is 21K gas units, that number must be multiplied by the average gas cost in Gwei to determine how much ETH you need for the transaction.Īll of this can be done in your digital wallet - most wallets that support ETH and Ethereum-based tokens will allow you to select the speed of your transaction and calculate the required amount of Gwei necessary to process your request.Ī gas cost exists so that the network can function properly. But, these gas units must be converted to Gwei, first. The example above touches upon how gas fees work in Ethereum. If a friend puts a gas limit of 100K for the same standard transfer, their transaction will be performed before yours in the line-up, although your transaction will still be processed before anyone who pays the fee of 21K gas units for a standard transaction. But if you specify 20K units for a standard transfer, your 20K units will be consumed but your transaction will not be complete. As a result, gas fees on Ethereum have risen as the platform has become more and more popular and adjusting to a higher gas price ensures that your transaction is prioritized.Īs an example, if you put a gas limit of 50K for a standard transfer (which we noted above is 21K gas units), the system would consume 21,000 units of gas and you would get back the remaining 29,000 units. ![]() Each person is trying to have their transaction executed at the same time, but there is a limit to the number of transactions that can be included per Ethereum block as each block contains only 12.5mn units of gas.Ī new block is created every 13 seconds but when demand is high and supply is constrained, the price increases. Well, when you submit a transaction on Ethereum, you are competing with others who also want to submit a transaction. If you would rather pay a lower gas fee, though, be prepared for your transaction to take a lot longer. Essentially, a priority is given to requests that are willing to pay higher gas fees. However, when you send a transaction request to the Ethereum network, how quickly your transaction is processed depends on the gas limit you are willing to pay. You can think of Gwei as cents, since 1 cent is. Gas fees are denoted in Gwei, which is just. A standard ETH transfer requires a gas limit of 21,000 units of gas. When you want to transact in ETH on the Ethereum platform, you have to pay a gas fee. ![]() Essentially, gas is like a toll on the highway and costs are often higher for larger or more complicated transactions, just as truck drivers pay higher tolls than smaller vehicles. ![]() In the cryptocurrency world, “gas” refers to the computational effort required to execute transactions on the platform in question. ![]() Similarly, cryptocurrencies also have fees to execute a contract or transaction on their platforms, like Ethereum, which are known as gas fees. In fact, with most financial transactions, we’re used to paying a fee, whether it’s a fee to withdraw money from an ATM or a fee to convert currency when abroad. Chances are you have paid an ACH fee when you transfer money into or out of your bank.
