If youâve ever paid a toll on a highway, then you already know something about Ethereum gas fees. Ethereum gas fees are like paying a âtollâ to use the Ethereum blockchain. Highway tollbooths may be operated by one person, but the Ethereum blockchain involves many decentralized operators.
Hereâs a quick guide to Ethereum gas fees, including what they are, how theyâre determined, and why they matter for your crypto portfolio.
Key Points
- Transaction processing fees on the Ethereum network are called gas.
- Gas prices for the Ethereum blockchain are influenced by network demand.
- Ethereum gas fees can be volatile and prohibitively expensive.
Ethereum gas is what users pay to process transactions or use smart contracts on the Ethereum network. Ethereum gas is denominated in gwei, short for gigawei, with one gwei equal to one billionth of an ETH. Ethereum gas fees can only be paid in Ethereumâs native token, Ether (ETH).
Ethereum gas fees exist because operating the Ethereum network uses resources in the form of computational power. Participants in the Ethereum network can voluntarily operate the blockchain to earn gas fees, provided that they stakeâthat is, agree not to trade or sellâtheir ETH.
Gas fees on the Ethereum network are determined by three variables:
- Complexity. Specifically, the amount of gas required to process a transaction.
- Base fee. The reserve price below which a transaction is ineligible for processing on the blockchain.
- Priority fee. An optional incentive fee to expedite processing time. (Itâs like a theme park FastPass or a tip to the headwaiter.)
Your total Ethereum gas fee is determined by adding the base fee to the optional tip and multiplying that sum by the amount of gas used.
How do Ethereum gas fees work?
Suppose you want to buy ETH for your crypto wallet. Hereâs the step-by-step process that illustrates how Ethereum gas fees work:
- You initiate a transaction. Using the platform or crypto exchange of your choice, you can initiate a transactionâto purchase ETH, in this example. You would input your desired purchase amount and other relevant information.
- You approve an estimated gas fee. The platform provides you with an estimate for the Ethereum gas fee. Many platforms and exchanges automatically evaluate current Ethereum gas fees and current network demand to suggest a gas fee that balances cost with transaction speed. If the estimated gas fee is acceptable, then you can submit the transaction for processing.
- The transaction is sent to the Ethereum blockchain. Your ETH purchase order is sent to the Ethereum network. The data included with the purchase order places an upper limit on the total gas fee that youâre willing to pay.
- A proof-of-stake validator creates a new block. Ethereum network validators assemble new blocks for the Ethereum blockchain by selecting which transactions to validate. Transactions with the highest gas fees typically get selected first, as theyâre the most profitable for validators. Your transaction is generally classified as complete once itâs included in a block and the block is added to the blockchain.
- Your digital wallet balance updates. With your transaction published to the blockchain, your Ethereum balance updates and the gas fee is withdrawn. Your transaction total is the ETH purchase amount plus the gas fee.
- The validator receives gas fees. The validator that processed your transaction receives the tip portions of your gas fee and the gas fees from all the transactions in the block. The base fees are âburnedââremoved from circulationâto prevent ETH currency inflation.
Why Ethereum gas fees matter for your investment portfolio
If youâre interested in owning or trading ETH, then itâs important to understandâand aim to minimizeâyour Ethereum gas fees.
You might already be familiar with the importance of minimizing fees as a mutual fund investor or a stock trader. Fees can eventually snowball into a big sum. So, even a seemingly small fee can have a compounding effect on the overall performance of your portfolio. Stock traders who frequently buy and sell shares can lose money on brokerage fees, and crypto traders can be caught by surprise by high gas prices.
The same principle of compounding fees applies to Ethereum gas fees and their potential overall effect on your crypto portfolio. Actively buying and selling on the Ethereum platform or participating in decentralized finance (DeFi) activities can cause you to pay gas fees that quickly add up. Andâunlike the mostly predictable fees charged by stock brokeragesâEthereum gas fees can (and do) spike.
One way to think about Ethereum gas fees is to consider them in the context of your expected return on investment. If you expect a high return or place high value on an Ethereum transaction, then you may be willing to pay a higher gas fee. But the smart move for cost-conscious investors is to always minimize your gas expenses.
How to monitor Ethereum gas prices
You can minimize what you pay in Ethereum gas by monitoring the prevailing Ethereum gas price. Does that sound like a lot of work? It doesnât have to beâplenty of online tools are dedicated to tracking gas prices on the Ethereum platform.
A few of the top gas fee monitoring tools include Etherscan, ETH Gas Station, and GasNow.* Additionally, many crypto platforms offer their own or a third partyâs gas monitor.
Each of these tools provides detailed information about Ethereum gas fees for slow, medium, and fast transactions on the Ethereum network. You can also find historical information, moving averages, and leaderboards that list the biggest gas guzzlers.
Why are Ethereum gas prices so volatile?
Just like gas prices at the pump, Ethereum gas fees can be volatile. If many traders, investors, and decentralized app users want to access the Ethereum blockchain, then the network can become congested. Ethereum blockchain users may be willing to pay more generous tips for their transactions to be completed quickly, driving gas prices up.
Ethereum gas prices can decline sharply for similar reasons. If network usage is low, then validators wishing to add blocks to the chain are likely to accept low tips. The constant change in network congestion creates continuous volatility for Ethereum gas fees. Ultimately, itâs a supply and demand thing.
Understanding Ethereum gas fees and how they work is key to avoiding what could be a major unexpected expense. For example, you donât want to be the one paying high Ethereum gas fees just because a trendy memecoin is creating network congestion.
Luckily youâre already on the right track just by reading this high-level overview of gas fees and how they work. If youâre transacting in ETH, be sure to monitor current gas fees and be relatively certain what the all-in (gas included) price will be.
