The Ethereum London Upgrade, implemented in August 2021, introduced significant changes to the network's fee structure. While not directly targeting scalability, it aimed to make transaction costs more predictable for users. Over half a year later, data reveals insightful trends about gas fees, user behavior, and network activity.
This analysis explores how gas fees have evolved, the adoption rate of the new EIP-1559 transaction type, and practical strategies users can employ to minimize their costs.
Understanding the London Upgrade's Impact on Fees
The London Upgrade fundamentally altered Ethereum's fee mechanism. Previously, users paid a single gas fee to miners. The upgrade split this into two distinct parts:
- Base Fee: A mandatory fee that is dynamically adjusted based on network congestion and is subsequently burned, permanently removing it from circulation.
- Priority Fee (Tip): An optional fee paid directly to miners to incentivize them to prioritize a transaction.
This new structure was designed to create a more predictable and efficient auction market for block space.
Overall Gas Price Trends
Contrary to some expectations, the London Upgrade did not lead to a consistent downward trend in the overall average gas price. Network demand, driven by DeFi, NFT, and GameFi activity, remains the primary driver of fee costs. The average gas price and average base fee have shown fluctuations aligned with market activity rather than a clear, sustained decrease.
The key change is in the composition of the fees. Data shows that the vast majority of a user's transaction cost is now the base fee, with priority fees typically constituting only about 15% of the total. This indicates that users are benefiting from the predictability of the new system, reducing the likelihood of overpaying.
A Shift in Gas Price Distribution
While the overall average might seem stable, a deeper look at the median gas price and distribution tells a more nuanced story.
The Move to Lower Fees
The median gas price has seen a slight decrease. Recent data shows a median price of approximately 72 Gwei, compared to around 79 Gwei in September 2021. More notably, the distribution of gas prices has shifted "left," meaning a higher proportion of transactions are now executed at lower fee levels.
- Approximately 50% of all transactions now occur at or below 60 Gwei.
- Nearly 90% of all transactions are completed for under 140 Gwei.
- This represents a 9% increase in transactions falling under the 60 Gwei threshold compared to data from September.
This shift is a direct result of increased user adoption of the EIP-1559 transaction type, which offers superior fee predictability.
EIP-1559 vs. Legacy Transactions
Adoption of the EIP-1559 standard has grown dramatically. In the six months post-upgrade, its usage has surged from less than 50% of all transactions to nearly 80%.
The data reveals a clear cost advantage for users who have switched:
- The median gas price for EIP-1559 transactions is 67 Gwei.
- The median gas price for legacy transactions is significantly higher at 83 Gwei.
Furthermore, the fee distribution for EIP-1559 transactions is smoother and more concentrated in lower price brackets. Over 51% of EIP-1559 transactions were executed below 70 Gwei, compared to only 35% of legacy transactions. This demonstrates that the upgraded fee mechanism is effectively helping a majority of users save on gas costs.

Identifying Patterns in Gas Fee Fluctuations
Gas fees are ultimately a function of supply and demand on the network. Analyzing historical data reveals consistent daily and weekly patterns that users can leverage.
Time-of-Day Analysis
Gas prices follow a predictable rhythm throughout the UTC day:
- Low-Cost Periods: The most affordable times to transact are between UTC 04:00 and 13:00. The lowest average price (around 76 Gwei) typically occurs near UTC 11:00.
- High-Cost Periods: Prices rise significantly in the afternoon and evening UTC, peaking around UTC 17:00 with average prices near 150 Gwei.
- Volatility: The variance in price is also higher after UTC 14:00, meaning fees are less predictable and can spike more easily during this window.
Choosing to transact during low-cost, low-volatility periods can reduce gas fees by nearly half.
Day-of-Week Analysis
A weekly pattern is also evident:
- Weekends: Sunday and Saturday generally offer the lowest average gas prices.
- Weekdays: Prices are highest on Thursday.
- Volatility: Saturday shows the highest price variance, while Sunday tends to be both low-cost and relatively stable.
For users looking for the best combination of low and predictable fees, Sunday presents an optimal window for transaction activity.
The Future of Ethereum Gas Fees
Many in the community look forward to Ethereum's full transition to a proof-of-stake (PoS) consensus mechanism and the implementation of sharding with Ethereum 2.0. These upgrades are designed to drastically increase network throughput and capacity, which should, in theory, alleviate congestion and reduce fees.
However, this transformation is a complex, multi-stage process that will unfold over time. In the immediate future, several factors could exert upward pressure on fees:
- Growing Demand: The rapid expansion of the crypto ecosystem, including new dApps, NFT projects, and blockchain gaming, continues to increase demand for block space.
- ETH Valuation: The London Upgrade's fee-burning mechanism is making ETH a potentially deflationary asset. If the price of ETH rises significantly, the fiat-equivalent cost of gas fees will also increase, even if the gas price in Gwei remains stable.
While fundamental scalability solutions are on the horizon, users today must remain savvy. Understanding data trends and adapting transaction habits are the most effective tools for managing costs. To make informed decisions, view real-time tools that can help you track these patterns.
Frequently Asked Questions
What was the main goal of the Ethereum London Upgrade?
The primary goal was not to lower fees but to make them more predictable. It introduced EIP-1559, which split fees into a burnable base fee and an optional tip, creating a better user experience and a deflationary pressure on ETH.
How can I pay less for Ethereum gas fees?
First, use wallets that support the EIP-1559 transaction type. Second, schedule your transactions for low-demand periods, typically weekend mornings UTC. Finally, avoid times of high network volatility, like during major NFT drops.
Will Ethereum 2.0 solve the high gas fee problem?
Ethereum 2.0, with its shift to proof-of-stake and sharding, is designed to massively increase network capacity, which should reduce congestion and lower fees. However, it is a gradual rollout, and high demand may continue to impact costs.
What is the difference between base fee and priority fee?
The base fee is a mandatory, algorithmically set fee that is burned. The priority fee (or tip) is an optional incentive paid directly to validators (miners) to prioritize your transaction in the next block.
Why are gas fees sometimes so high?
Fees are determined by auction-style dynamics. When many people want to use the network simultaneously (e.g., for a popular NFT mint), users bid higher priority fees to get their transactions processed first, driving up the cost for everyone.
Is it better to use EIP-1559 or legacy transactions?
Data shows that EIP-1559 transactions consistently have a lower median cost and more predictable pricing. It is generally recommended to use the new standard for most transactions.
