The cost of transacting on the Ethereum network has reached a five-year low, signaling a major shift in user behavior and network dynamics. As of August 10, the median gas fee for sending an Ethereum (ETH) transaction dropped to just 1.9 gwei, with low-priority transactions falling below 1 gwei—a level not seen since mid-2019. This dramatic reduction reflects declining congestion on the Ethereum mainnet, driven largely by the rapid adoption of Layer-2 (L2) scaling solutions.
This trend underscores a broader transformation within the Ethereum ecosystem: users and developers are increasingly migrating to L2 networks for faster, cheaper transactions, leaving the Layer-1 (L1) chain with significantly reduced activity.
The Dencun Upgrade: Catalyst for Lower Gas Fees
The sharp decline in gas prices coincides with the successful implementation of the Ethereum Dencun upgrade in March 2024. This pivotal network update introduced nine Ethereum Improvement Proposals (EIPs), most notably EIP-4844, which enables “proto-danksharding”—a foundational step toward full sharding.
Proto-danksharding introduces data blobs, temporary storage units that allow Layer-2 rollups to offload transaction data more efficiently to Ethereum’s main chain. By reducing the data burden on L1, this innovation dramatically lowers costs for L2 networks like Arbitrum, Optimism, and Base.

According to Dune Analytics, median gas prices plummeted from a year-to-date high of 83.1 gwei in March to just 1.9 gwei by mid-August—a staggering 98% decrease. This makes Ethereum transactions more accessible than ever, even as core activity shifts off the mainnet.
Prior to Dencun, high gas fees were a persistent pain point during periods of network congestion. Now, with L2s handling the bulk of transactions, Ethereum L1 is operating at historically low utilization levels.
Why Lower Gas Fees Matter
Low gas fees are often seen as a positive development, but they also raise important questions about Ethereum’s long-term economic sustainability.
When gas fees fall too low, it reduces the revenue earned by validators who secure the network through staking. Martin Köppelmann, co-founder of Gnosis, highlighted this concern in a widely shared post on X (formerly Twitter):
"Basefee right now at a multi-year low of ~0.8 GWEI. 23.9 would be required to offset staking rewards. IMO Ethereum needs to get more L1 activity again and even if it sounds counterintuitive at such low rates, raising the gas limit can be part of a strategy."
Köppelmann’s insight reveals a critical challenge: a healthy blockchain economy requires sufficient transaction demand to sustain validator incentives. At current fee levels, Ethereum may struggle to maintain long-term security without adjustments to its fee or issuance model.
Still, for users and developers, low fees mean lower barriers to entry, increased experimentation, and broader adoption—especially for decentralized applications (dApps) that rely on frequent microtransactions.
Layer-2 Networks Drive the Shift
The exodus from Ethereum L1 to L2 solutions is not just theoretical—it’s backed by hard data.
According to L2Beat, Base, Coinbase’s Layer-2 network, processed over 109 million transactions in the past 30 days, far surpassing Ethereum’s own 33 million during the same period. This surge comes less than a year after Base’s official launch and was further accelerated by Coinbase’s strategic move to migrate customer-held USDC stablecoins to the Base chain in March 2024.
Other major L2 platforms are also thriving:
- Arbitrum and Taiko combined recorded nearly 97 million transactions in the last month.
- These networks leverage Ethereum’s security while offering near-instant finality and sub-cent transaction costs.
This migration reflects a maturing ecosystem where Ethereum acts as a settlement layer, while L2s handle day-to-day operations. It’s a model often described as “modular blockchain architecture”—a design that separates execution, consensus, and data availability across specialized layers.

Implications for Ethereum’s Ecosystem
The shift toward L2 dominance has broader implications:
1. Reduced Pressure on L1
With most transactions occurring off-chain, Ethereum’s mainnet experiences less congestion, improving stability and predictability for critical operations like smart contract deployments and cross-chain bridges.
2. Increased ETH Supply Pressure
Recent data shows that over 13,400 ETH (~$34.1 million) was added to circulating supply in just seven days—partly due to reduced transaction burn from low fees. With fewer fees being burned (via EIP-1559), net issuance may rise unless offset by higher staking withdrawals or future upgrades.
3. Need for Economic Rebalancing
As Martin Köppelmann suggests, Ethereum may need to reconsider its gas limit policy or explore new mechanisms to incentivize L1 usage—such as native account abstraction, enhanced smart contract functionality, or mandatory on-chain verification steps for certain L2 outputs.
Frequently Asked Questions (FAQ)
Q: Why are Ethereum gas fees so low right now?
A: Gas fees have dropped due to reduced network congestion, primarily because most transactions have moved to Layer-2 networks like Base and Arbitrum. The Dencun upgrade also improved data efficiency, lowering demand on the mainnet.
Q: Is low gas fee good or bad for Ethereum?
A: It's beneficial for users seeking affordable transactions but potentially concerning for network security. Lower fees mean less revenue for validators, which could impact long-term economic sustainability if not addressed.
Q: What is proto-danksharding?
A: Proto-danksharding (via EIP-4844) allows Layer-2 rollups to store transaction data off the main Ethereum chain temporarily using “data blobs.” This reduces data load and cuts costs significantly.
Q: How do Layer-2 networks reduce gas fees?
A: L2s batch hundreds or thousands of transactions off-chain and post a single proof to Ethereum L1. This minimizes data usage on the mainnet, resulting in much lower costs per transaction.
Q: Will Ethereum gas fees stay this low?
A: It depends on user behavior and protocol evolution. If L2 adoption continues growing, L1 fees may remain low unless new use cases (like AI contracts or identity systems) drive fresh demand.
Q: Can I still make money validating Ethereum with low fees?
A: Yes—validators still earn staking rewards in ETH. However, they no longer receive as much in priority fees (tips), and fewer fees are burned, which affects overall tokenomics.
Conclusion
Ethereum’s record-low gas fees are both a triumph and a challenge. They reflect the success of scaling innovations like the Dencun upgrade and widespread Layer-2 adoption—proving that scalable, affordable blockchain access is achievable.
Yet, they also expose vulnerabilities in Ethereum’s current economic model. As the network evolves into a modular architecture with L1 as a settlement layer, developers and stakeholders must ensure that core incentives remain aligned.
The future of Ethereum may not be measured by how many transactions it processes directly—but by how securely and efficiently it supports an entire ecosystem built atop it.
