Ethereum remains the second-largest cryptocurrency after Bitcoin, but its main advantage is not only its financial value. At the time of writing, ETH is trading at around $2.92K with a market capitalization of $352.98B. The reason for its popularity is simple: decentralized applications and smart contracts operate on this blockchain platform, which have literally transformed the crypto space.
However, there is one “headache” for all users – gas fees. If you’ve ever bought or sold an NFT on Ethereum, you’ve likely encountered unexpectedly high processing fees. These fees are not network whims but a necessity to compensate for computational resources.
What’s Behind Gas in Ethereum
Imagine a car that needs gasoline. Ethereum works similarly, but instead of gasoline, it uses gas. This is a measurement unit that indicates how much “fuel” your transaction requires to be executed.
Each operation on the network requires a different amount of gas:
Simple ETH transfer: 21,000 units
ERC-20 token transfers: 45,000–65,000 units
Interacting with a smart contract: 100,000 units or more
The gas price is measured in gwei (1 gwei = 0.000000001 ETH). The total fee is calculated simply by multiplying: gas amount × gas price.
For example: you send ETH with a gas price of 20 gwei.
Gas required: 21,000 units
Gas price: 20 gwei
Total fee: 21,000 × 20 = 420,000 gwei = 0.00042 ETH
NFTs and Actual Purchase Cost
When it comes to NFTs, the situation becomes more complex. An operation involving a non-fungible token requires interaction with a smart contract, which means significantly more gas than a simple transfer.
Here are typical scenarios:
Operation
Gas Required
Approximate Cost at 20 gwei
Simple ETH transfer
21,000
0.00042 ETH
Minting an NFT
100,000+
0.002 ETH+
Buying on a marketplace
120,000–200,000
0.0024–0.004 ETH
Creating an NFT collection
150,000+
0.003 ETH+
Important note: during peak activity periods (for example, when everyone rushes to a new NFT project or meme coin surges), gas prices can increase 5-10 times. A transaction that cost $1 can suddenly cost $5-10.
The EIP-1559 Revolution: When the System Finally Became Fair
Until August 2021 (London Hard Fork), users participated in an auction for space in a block. Everyone bid different prices, creating chaos and unpredictability. It was a bidding war.
EIP-1559 changed the game. Now, the system works as follows:
Base fee is set automatically based on network demand
This base fee is burned (removed from circulation), reducing the total ETH supply
Users can add tip (priority fee) to speed up processing
Result? Fees have become more predictable. You know exactly the minimum amount that will be spent and can add a little more for priority if you’re in a hurry.
Why Gas Prices Spike: Main Reasons
Demand and competition in the network
When many users want to do something simultaneously (for example, everyone tries to buy a popular NFT), they compete for a spot in the block. It’s like an auction – the price rises because everyone says: “I’m willing to pay more to get my transaction processed first.”
Operation complexity
Interacting with a complex smart contract (for example, on Uniswap) requires more computations than a simple transfer. This directly affects the amount of gas needed.
Network congestion
Ethereum can process about 15 transactions per second. When traffic exceeds this capacity, gas prices increase exponentially.
How to Track and Plan Expenses
Several tools can help you avoid overpaying:
Etherscan Gas Tracker - the most reliable source. Shows current gas prices by categories (low, standard, high speed) and provides estimates for specific operations: swaps, NFT sales, token transfers.
Blocknative offers real-time data on gas trends and helps predict when prices will drop.
Milk Road - for visually oriented users. Heat maps and charts show when network load is minimal (usually weekends or early mornings in the US).
Tips for Saving on Gas
Choose the right timing
Transactions on weekends tend to be about 30-40% cheaper. Early morning hours (UTC) are the best period for savings.
Use “standard” or “slow” priority levels
If you’re not in a rush, choose the cheapest option. The transaction will just take longer but will still go through.
Switch to Layer 2 solutions
This is where real magic happens. Second-layer networks process transactions off the main Ethereum chain, significantly reducing load.
Examples of solutions:
Optimism and Arbitrum (Optimistic Rollups) bundle multiple transactions and record them as a single batch
zkSync and Loopring (ZK-Rollups) use cryptographic proofs for verification
Results are impressive: a transaction on Loopring costs less than $0.01, while doing the same on the mainnet costs several dollars. Throughput increases from 15 TPS to about 1000 TPS thanks to the Dencun upgrade (EIP-4844 proto-danksharding).
Batch processing
Instead of sending five separate transactions, send them simultaneously via specialized interfaces. This saves gas.
What’s Coming in the Future: Ethereum 2.0 and Beyond
Ethereum 2.0 promises a revolution. The shift from Proof of Work to Proof of Stake (has already happened on the Beacon Chain), reducing energy consumption and increasing throughput.
Development strategy includes:
The Merge - already completed
Sharding - splitting the network for parallel processing
Dencun - already active, improves efficiency
Long-term goal: reduce fees to less than $0.001 per standard operation.
Frequently Asked Questions
Why do I pay gas for a failed transaction?
Because validators still spent resources processing it. The fee is for work done, not the result.
How to fix the “Out of Gas” error?
The gas limit was too low. Increase it on retry, making sure it covers the complexity of the operation.
What’s better for NFT: standard or fast gas?
For NFTs, it’s recommended to choose standard or fast depending on urgency. During peak demand, even fast gas can be expensive.
How to reduce fees?
Wait for off-peak times, use Layer 2 networks, monitor Etherscan, plan ahead.
Final Advice
Mastering the Ethereum gas system is not only a way to save money but also a key to efficient blockchain use. With the right understanding of mechanics, tracking tools, and timing strategies, you can buy NFTs, swap tokens, and interact with smart contracts without unnecessary overpayments. And with the development of Layer 2 solutions and upcoming Ethereum upgrades, the future looks even more promising.
