Projected Fee Reductions
Published 6/19/2026, 5:43:32 AM
The Glamsterdam upgrade is a proposed Ethereum protocol upgrade currently in development and scheduled for activation in H2 2026 [Source: https://ethereum.org/roadmap/glamsterdam]. While some reports suggest a target fee reduction of approximately 78%, these figures are forward-looking projections rather than realized data, as the upgrade has not yet been implemented.
Projected Fee Reductions
The 78% reduction claim is based on a massive increase in network capacity and structural changes to how transactions are processed. If the upgrade meets its technical targets, the estimated cost shifts for standard operations are as follows:
| Transaction Type | Pre-Upgrade Cost (Est.) | Post-Upgrade Target |
|---|---|---|
| Simple ETH Transfer | $2.00 – $5.00 | ~$0.025 |
| ERC-20 Transfer | $5.00 – $15.00 | ~$0.076 |
| Uniswap Swap | $3.00 – $8.00 | $0.21 – $0.80 |

Technical Mechanisms for Fee Reduction
The Glamsterdam upgrade (tracked as EIP-7773) relies on four primary pillars to achieve these efficiency gains:
- Parallel Execution (EIP-7928): Introduces Block-Level Access Lists (BALs) that pre-declare state dependencies. This allows the network to process non-conflicting transactions simultaneously rather than one-by-one, aiming for a 3-4x throughput gain [Source: https://everstake.one].
- Capacity Expansion: The upgrade proposes raising the block gas limit from 60 million to 200 million, with a target throughput of 10,000 TPS [Source: https://phemex.com/blogs].
- Enshrined Proposer-Builder Separation (ePBS - EIP-7732): Moves block-building coordination directly on-chain. This is intended to eliminate reliance on external relays and reduce MEV extraction by up to 70% [Source: https://ethereum.org/roadmap/glamsterdam].
- Gas Repricing (EIP-7904): Recalibrates gas costs to favor computation over state creation. While this makes transactions cheaper, it may increase the cost of deploying new contracts to prevent "state bloat."
Critical Nuances and Risks
- Activation Status: [Verified: https://ethereum.org/roadmap/] Contrary to some reports claiming the upgrade is live, official Ethereum documentation confirms it is still "In development" as of early 2026.
- The "Glamsterdam Paradox": A 78% reduction in fees would significantly lower the amount of ETH burned via EIP-1559. This could potentially end Ethereum's "ultrasound money" deflationary trend, even if network utility increases.
- Demand Elasticity: Lower fees typically invite higher demand. If the 10,000 TPS capacity is quickly filled by new use cases, the "market price" for gas could rise again, negating some of the projected savings.
Conclusion
The 78% fee reduction is a theoretical target based on increasing the gas limit to 200 million and implementing parallel execution. While the technical roadmap supports the possibility of such a reduction, it cannot be confirmed until the upgrade's scheduled launch in the second half of 2026.
Next Steps:
- Would you like a technical deep dive into EIP-7928 (Parallel Execution) to see how it compares to Solana's execution model?
