As an NFT enthusiast, DeFi investor, trader, or Ethereum project developer, understanding when gas fees are at their lowest can save you significant costs. This guide explores the best times to transact on Ethereum and strategies to minimize gas expenses.
Understanding Ethereum Gas Fees
Every Ethereum transaction incurs gas fees, determined by network supply and demand. Key factors influencing gas costs include:
- Current network demand for gas
- Computational complexity of smart contracts
- Total transaction volume
- Size of the smart contract being executed
Major Causes of Gas Fee Spikes
1. DeFi Boom Drives First Major Gas Peak
Ethereum pioneered smart contracts, enabling developers to build decentralized applications (DApps). The 2020 DeFi summer saw gas prices surge 20x, with DeFi remaining a dominant force in 2022—processing thousands of daily smart contracts.

2. NFT Minting and Trading Escalate Gas Fees
The 2017 CryptoKitties craze caused Ethereum's first major congestion, raising gas fees from 0.002 ETH to 0.008 ETH. Today, platforms like OpenSea and LooksRare fuel NFT trading, spiking gas fees during high-demand mints.
3. High Gas Consumption Trends
Over the past five years, average gas fees have peaked at $100 per transaction, notably during August 2021's play-to-earn and NFT boom. This demand accelerated Layer 2 networks like Polygon, Avalanche, and BSC.
Optimal Times for Low Gas Fees
Based on historical data (UTC timezone):
- Avoid: Weekday mornings (1 AM–5 AM UTC), especially Fridays.
Best windows:
- Weeknights: 9 PM–11 PM UTC
- Weekends: Saturday/Sunday evenings (10 PM–11 PM UTC lowest)

Pro Tip:
Schedule transactions when fewer users are active—typically outside standard "office hours."
FAQ
Q1: Why do gas fees fluctuate hourly?
A1: Fees reflect real-time network congestion. High activity (e.g., NFT drops) creates spikes.
Q2: Are weekends consistently cheaper?
A2: Generally yes, but monitor real-time trackers—events can override typical patterns.
Q3: How do Layer 2 solutions reduce costs?
A3: They process transactions off-chain, bundling them for cheaper mainnet settlement.
Q4: Should I always wait for low-fee periods?
A4: Balance urgency vs. savings. For small transactions, fees may be negligible.
Q5: Can I predict future gas trends?
A5: While historical patterns help, unexpected events (e.g., token launches) can disrupt trends.
