Ethereum’s Glamsterdam upgrade has delivered on its headline promise: record transaction volumes and gas fees that have fallen by roughly 78% since the hard fork activated. The results are reshaping how developers and users think about activity on Ethereum’s base layer.
The upgrade, which targets both throughput and fee sustainability simultaneously, has produced all-time high transaction counts on Ethereum Layer 1 – a notable reversal for a network that had been ceding activity to its own rollup system as base layer fees climbed.
What Glamsterdam Changed
Glamsterdam introduced several interconnected improvements. Parallel transaction processing allows the execution environment to handle non-conflicting transactions simultaneously rather than sequentially. On-chain block building was restructured to reduce bottlenecks in how transactions are ordered and included. And the gas limit was raised to 200 million – a roughly 2.5x increase over the pre-Glamsterdam ceiling.
The combined effect on fees has been significant. Ethereum.org’s official plan page describes the upgrade’s purpose: “Adjusting network fees to accurately reflect the long-term hardware cost of storing new data, unblocking future gas limit increases while preventing hardware performance degradation.”
In plain language: Glamsterdam makes Ethereum’s base layer cheaper to use without sacrificing the network’s long-term sustainability.
The Fee Numbers
Before Glamsterdam, simple ETH transfers routinely cost $2-$8 during periods of moderate demand, with complex DeFi interactions reaching $30-$100 or more at peak congestion. Following the upgrade, transfer costs have dropped below $0.50 for most activity, and complex smart contract calls have fallen proportionally.
The 78% reduction cited across multiple analyses reflects median fee conditions across both simple and complex transaction types. Coinfomania, which tracked the upgrade’s initial performance, reported “record transactions and 78% lower gas fees, boosting DeFi growth and Layer 1 scalability.”
These numbers will fluctuate with network demand, but the structural changes mean that the gas limit ceiling that previously caused fees to spike has been substantially raised.
Impact on DeFi
The fee reduction has immediate consequences for DeFi protocols that had been partially displaced to Layer 2 networks by high L1 costs.
Smaller trades, more frequent interactions, and liquidity management operations that were economically unviable at $20+ gas costs become feasible at sub-dollar fees. Several DeFi protocols have already reported increases in direct L1 activity following the Glamsterdam activation.
The active also affects how Ethereum competes with lower-fee chains. One of the consistent criticisms of Ethereum from Solana, Avalanche, and other alternative Layer 1 advocates has been base layer transaction cost. Glamsterdam narrows that gap substantially.
The Throughput Story
Beyond fees, Glamsterdam’s parallel execution and gas limit increase have raised Ethereum’s raw transaction throughput. The network is processing more transactions per second on L1 than at any previous point in its history, according to on-chain data reviewed by Phemex’s analysis team.
The upgrade is also being watched as a signal of whether Ethereum can scale its base layer without full migration to a rollup-centric model. For years, the prevailing Ethereum development philosophy held that L1 would handle settlement while rollups handled execution. Glamsterdam challenges that assumption by making L1 execution meaningfully more competitive.
What Critics Are Watching
Not everyone expects the fee gains to hold. When the gas limit was raised in earlier Ethereum upgrades, demand eventually caught up, pushing fees back up. The question for Glamsterdam is whether parallel execution and structural efficiency improvements change that active – or whether the network simply absorbs the extra capacity and returns to congestion at higher throughput levels.
Developers are also monitoring whether the shift to parallel execution introduces new edge cases in smart contract behaviour, particularly for contracts written with sequential execution assumptions.
The Ethereum Foundation hasn’t officially commented on projected fee sustainability, but the ethereum.org plan language about “ensuring performance stays high” as capacity increases suggests the development team is aware of the demand absorption risk.
FAQ
what’s the Ethereum Glamsterdam upgrade? Glamsterdam is Ethereum’s latest hard fork, introducing parallel transaction execution, on-chain block building improvements, and a gas limit increase to 200 million. The upgrade has produced a 78% reduction in gas fees and record transaction throughput on Ethereum Layer 1.
How much have gas fees dropped after Glamsterdam? Median gas fees have dropped approximately 78% compared to pre-Glamsterdam averages, bringing simple ETH transfers below $0.50 and significantly reducing costs for DeFi and smart contract interactions.
Will Glamsterdam permanently lower Ethereum gas fees? Glamsterdam raises the structural capacity of the network, which should sustain lower fees under equivalent demand conditions. However, if demand scales proportionally with the new capacity, fees will rise again. The upgrade changes the ceiling, not the demand curve.
