If you've ever purchased an NFT, especially on the Ethereum blockchain, you've likely been surprised by the high transaction costs, commonly known as Gas Fees. This article explains why these fees can be so expensive and shares practical strategies to reduce them.
What Are Gas Fees and Who Receives Them?
Gas Fees are not paid to the NFT project team or the seller, nor are they paid to marketplaces like OpenSea. Instead, these fees go to the miners on the blockchain network, with a portion of the Ethereum being permanently destroyed.
Anyone with the right knowledge and equipment—such as graphics cards used in mining rigs—can become a miner. Miners are responsible for recording transactions on the blockchain, and they receive Gas Fees as compensation for their work.
What Causes a Gas War?
Gas Fees are not fixed. When a transaction occurs on the blockchain, it enters a mempool (transaction pool). Miners prioritize transactions that offer higher Gas Fees, processing them first to maximize their earnings.
This system leads to Gas Wars during popular NFT launches. Buyers manually increase their offered Gas Fees to ensure their transactions are processed quickly, driving up the overall cost. If you only set aside the exact amount for the NFT's listed price, you will likely miss out due to these competing fees.
How to Reduce Gas Fees
For those without technical expertise, here are some effective ways to minimize Gas Fees:
Monitor Timing
Gas Fees spike when transaction demand is high. Avoiding peak times is one of the simplest and most effective strategies.
For users in Taiwan, weekdays during the afternoon and early evening often offer lower fees, as users in Europe and North America are less active. Observing Gas Fee trends between 4 PM and 6 PM local time can help identify favorable rates.
Choose the Right Blockchain
While Ethereum is known for high fees—earning it the nickname "the noble chain"—other blockchains like Solana and Tezos offer significantly lower transaction costs.
As a general rule, when purchasing NFTs on Ethereum, allocate around 40% of the NFT's price for Gas Fees. For highly sought-after projects, consider setting aside even more. On other blockchains, 10% is often sufficient.
Understand Protocols
Most NFTs on Ethereum use the ERC-721 standard. However, newer protocols like ERC-721a, used by the popular Azuki project, significantly reduce Gas Fees during minting. As more projects adopt efficient protocols, understanding the underlying technology can help you save money and assess the seriousness of NFT projects.
Use Monitoring Tools
Installing browser extensions like the DeFi Saver Gas Prices Extension allows you to monitor real-time Gas Fees directly from your browser. Over time, you'll learn to recognize what constitutes a "low" fee.
Many users find fees below 70 Gwei acceptable, though this may vary based on personal preference and market conditions.

Frequently Asked Questions
Why are Ethereum Gas Fees so high?
Ethereum’s popularity and limited scalability lead to network congestion. When many users transact simultaneously, miners prioritize higher fees, causing overall costs to rise.
Can I avoid Gas Fees entirely?
While you can’t avoid them completely, choosing less congested blockchains, transacting during off-peak hours, and using efficient protocols can significantly reduce costs.
Do all NFTs have high Gas Fees?
No. Fees depend on the blockchain. Ethereum typically has the highest fees, while networks like Solana and Tezos are more affordable.
What happens if I set my Gas Fee too low?
If your fee is too low, miners may ignore your transaction, causing delays or failed transactions. It’s better to pay a competitive rate during high-demand periods.
Are Gas Fees the same for buying and selling?
Yes, both buying and selling NFTs require Gas Fees, as each transaction needs to be validated on the blockchain.
How do I know if a Gas Fee is reasonable?
Use gas tracking tools to compare current rates with historical averages. Fees tend to be lower during nights and weekends in North American and European time zones.
Final Thoughts
Navigating Gas Fees is essential for anyone involved in the NFT space. By understanding what influences these costs and adopting smart strategies, you can make more informed decisions and reduce unnecessary expenses.
