![]() You can adjust the max fee and pay more to execute the transaction. In Metamask in particular, the max fee equals the base fee plus tip. But wait… What is the “max fee” I see in my wallet? Generally, if there’s a transaction you need to execute quickly, a higher tip is a good bet that the miners will pick it up sooner. You can set the tip as high or low as you want, and some wallets will provide a suggestion. To continue providing incentives for the miners, the London upgrade now allows users to set the tip, i.e. With the London upgrade, the base fee is determined by the network, and once paid, the ether is burned, i.e. Prior to this upgrade, the base fee was determined through users bidding to get included in the block. TipĪlso known as the priority fee, this is another London upgrade innovation. The base fee changes based on the current network demand, going up when more users are all trying to get transactions written to the blockchain at the same time. The good news with the London upgrade is that the fee is calculated based on previous blocks, making gas prices more predictable. Each block has a minimum base fee that needs to be met for a transaction to be included. The London upgrade introduced the base fee, which is expressed in gwei. While most wallets give you a choice of a low, medium or high gas limit, you can also manually set your limit (for instance, making it even higher if you’ve got a transaction you want to be certain gets completed quickly). Anything less than that means your transaction won’t get picked up and processed by miners.Īs transactions get more complex, the 21,000 limit required to execute the transaction increases. ![]() It’s expressed by units - for example, for basic Ethereum transactions, the minimum gas limit is at least 21,000 units. Gas limit represents the total amount of gas you want to spend per transaction. Gas fee = gas units (limit) * (base fee + tip) This was especially true before the London upgrade, which was implemented in August 2021.Ĭurrently, the gas price is calculated through the following formula: Unlike something like an ATM fee, which is a fixed charge regardless of how much money you’re taking out, the gas fee can vary widely, which is a headache for users. When every transaction has a cost, it’s not so easy to send thousands of spammy transactions per second! How Are Gas Prices Determined? Gas fees are not only an incentive for miners, they also serve to prevent users from spamming the network with malicious or unnecessary transactions. Instead of saying your gas fee cost 0.000000001 ETH, you can just say it cost 1 gwei. Think of it like this: gwei is to ether what pennies are to a dollar. However, gas prices are usually expressed in gwei - a denomination of ether. Gas fees are paid in ether, the Ethereum native currency. The gas fee is the price users need to pay to cover some of the costs associated with the computational work and resources needed to run the network. Gas is a unit that describes the amount of computational work miners need to do. ![]() Miners need an incentive to perform that work - which is where gas comes in. Since Ethereum is currently a proof-of-work network (with a planned transition to proof-of-stake later this year - more on that later), every transaction needs to be processed and validated by miners. Similar to how its physical namesake is needed to make a car go, gas is what makes the blockchain operate smoothly. You have to pay gas on every transaction, whether it’s buying an NFT or swapping tokens, in order to pay for the resources required to make that transaction happen on the Ethereum blockchain. There are several essential components to any interaction that happens on the Ethereum blockchain - one of those components is gas.
