While these transactions differ in size, form, and nature, they all have one thing in common: they require users to pay gas fees. But what are gas fees and why are they necessary?This article explains what Ethereum gas fees are, why they can be expensive, and how you can pay lower fees.Ethereum gas fees are the transaction fees users pay on the Ethereum blockchain to conduct transactions and execute smart contracts. Users pay this fee in Ether (ETH), while the network nodes earn a fraction of fees for validating transactions via Ethereum's Proof of Stake (PoS) consensus mechanism.How are gas fees calculated?To best understand how gas fees are calculated, we'll first need to clearly define a few terms.1. Gas: Gas is the unit that measures computational power required to conduct a transaction, which varies depending on the complexity of the transaction. The computation and gas units needed for a simple token swap, for example, will be much lower than for minting an NFT or publishing a smart contract. 2. Gas price: The gas price is the price per unit of gas, and it is measured in gwei, a smaller unit of ETH that equals 0.000000001 ETH (10-9 ETH). (Conversely, 1 ETH equals 1 billion gwei).3. Gas fees: Gas fees are the final fees paid by users to complete a transaction.

Save money on Bitcoin and Ethereum transaction feesAs we've shown you in this article, there are many cryptocurrencies out there that have much lower transaction fees than Bitcoin and Ethereum. However, there are also ways to save money on transaction fees for users of these top two cryptocurrencies. Both Bitcoin and Ethereum developers are well aware that the transaction fees charged by these networks are high. The most common way to address high transaction fees is layer 2 solutions, which move some operations away from the underlying blockchain to save on fees.For example, most layer 2 solutions for Ethereum bundle up a large number of transactions into "rollups", which are then posted to the Ethereum mainnet. This allows them to offer much lower transaction fees to users while retaining the security benefits of the Ethereum mainnet.There are currently Ethereum layer 2s based on optimistic rollups (for example, Arbitrum and Optimism) and zero-knowledge rollups (for example, Polygon zkEVM and zkSync).Generally speaking, layer 2s based on optim+istic rollups are further along in their development and already provide similar functionality to the Ethereum mainnet. Meanwhile, zero-knowledge rollup technology is at an earlier stage of development but could provide even more impressive speeds and efficiency than their optimistic counterparts. Meanwhile, the leading Bitcoin layer 2 solution is Lightning Network, which achieves lower costs and faster speeds for BTC users through a network of payment channels. The bottom line — Choose the right coins and save on feesEven though transacting with Bitcoin and Ethereum can

Scalability would mean potentially much lower network congestion. In theory, this means transactions will go through without any problem even during times of high volume.Want to see live Ethereum price and market metrics?

If this occurs, the amount of gas would still get deducted from your wallet but the transaction wouldn't go through. It may be a good idea to first check the minimum gas price at any given time across various Ethereum calculators to ensure your transactions don't fail.Sample ETH gas fees in Gwei by transaction speed (Image source)How can I choose the correct gas price?Ethereum's London upgrade has removed uncertainty from gas price calculations. Now, whenever you conduct a transaction, there is always a base fee attached to it that the network decides and you cannot change. However, you can add a priority fee as a tip to validators and expect them to pick your transaction sooner. The gas unit (and thus the gas fee) needed for different kinds of transactions is different. For instance, you will need to pay considerably more for complex transactions such as executing a smart contract.Are there gas fees when buying Ethereum? Depending where you buy Ethereum, you'll need to factor in gas fees when completing your purchase.MoonPay Balances is a cheaper and faster way to purchase Ethereum (ETH) with higher approval rates. To get started, just top up your wallet in euros, pounds, or dollars and use your MoonPay Balance to purchase crypto like ETH. Plus, enjoy zero-fee withdrawals directly to your bank account when you decide to cash out.How can I pay lower gas fees?Even with fixed base fees, there's no certainty that the ETH gas fees will be low. It all depends on network congestion.To avoid paying high gas prices, you can do any (or all) of these three things:1. Plan aheadSchedule your transactions for times with less network congestion. Try not to

Transact during popular NFT mints, as the network may get congested.You can check future NFT drops on NFT rarity sites like Rarity Sniper and rarity.tools.2. Adjust transaction fees in your walletMost Ethereum wallets like MetaMask will allow you to preview the estimated gas price and transaction costs that you'll pay. You can generally alter these numbers in the advanced gas settings within the wallet. 3. Use an external calculatorSeveral tools can show you what current gas prices look like.
