Want to know when to submit ETH transactions to save on fees? This article explores the "when are ETH gas fees lowest" perspective to help you find the best time periods and provides easy-to-follow tips that even newbies can implement right away.

What is ETH Gas fee? Understand it thoroughly.

In the Ethereum ecosystem, every transaction or smart contract execution requires the consumption of “Gas” - the “fuel” of network resources. The Gas fee you pay = (number of Gas units) × (price per unit), with the unit typically being gwei. This fee is used to pay validators for processing the transaction. For example, a simple transfer of ETH may only require about 21,000 gas units, while complex contract operations may require more. The level of fees depends on two factors: the price per unit (affected by network congestion) and the number of gas units (affected by transaction complexity).

The key factors affecting gas fees

The main factors affecting ETH Gas fees include:

  • Network congestion level: When many users are operating on the chain simultaneously (such as NFT minting, DeFi interactions), competition intensifies, and the base fee increases.
  • Time zones and active user demographics: User activity times differ in major markets such as Europe and America, and Asia. The higher the activity level during certain periods, the higher the fees.
  • Transaction Type/Complexity: Contract interactions consume more gas units than simple transfers, which naturally incurs higher fees.
  • Tool and strategy usage: Using L2 networks, manually selecting trading times, and monitoring Gas prices can all help reduce costs.

Best Trading Time Revealed: When is the ETH Gas Fee the Lowest?

So, when is the best time to trade with the lowest fees? Here is a summary of the best time periods:

  • Weekdays late at night / early morning (Eastern Standard Time): from 12 AM to 4 AM EST, it is a period when most people in Europe and America are resting and online activity decreases.
  • Weekend early morning: Such as Saturday or Sunday 2 AM - 3 AM EST, is a time when many users around the world are inactive, and network congestion is the lightest.
  • Based on UTC: Observational data shows that the network is relatively quiet from 1 AM to 5 AM UTC; for Asian users, this roughly corresponds to the morning or evening hours.
  • Avoid peak hours: For example, during European and American office hours, popular NFT (drop) or DeFi events, fees often suddenly increase.

It should be noted that while these time periods generally have low fees, it cannot be guaranteed that they will always be the “lowest” each time, as network conditions can change rapidly. It is still very important to use real-time tools for monitoring.

Practical Strategies: How Newbies Can Avoid High Fees?

  • Plan your trades in advance: If your trade is not urgent (such as transfers, reserving assets, etc.), you can choose to submit during the low fee periods mentioned above.
  • Use monitoring tools: Open the Gas fee tracker (such as Etherscan Gas Tracker, QuickNode Gas Tracker) to observe the current base fee and priority fee.
  • Set a reasonable priority fee: If the wallet allows, choose the “slower but lower fee” option, suitable for non-urgent transactions.
  • Try Layer-2 networks: Users who frequently operate can switch to networks like Polygon, Arbitrum, and Optimism, where transaction fees are usually much lower than on the mainnet.
  • Avoid peak activity periods: During popular NFT sales or the launch of new DeFi projects, congestion often occurs, so try to avoid these times.

Summary: Get on the low-fee time train

If you want to save on ETH transaction fees, the rule “when are ETH gas fees lowest” is very useful: choose the time period when the fewest global users are active, allowing the network to “calm down” before you proceed. Newbies just need to remember: late night/early morning + weekend = low fees and high cost-effectiveness, so they can take the lead in practical operations. Before initiating a transaction next time, it might be a good idea to spend a minute checking the gas fees before deciding whether to “wait a bit.” This way, you are not just a participant in the transaction but also a smart strategy user. Wishing you smooth operations and the lowest fees!
