Ethereum is preparing its most ambitious network upgrade since The Merge, and the numbers behind it are hard to ignore. The Glamsterdam hard fork — a combined update to both the Execution Layer (Amsterdam) and the Consensus Layer (Glamour) — has locked in a 200 million gas limit floor, a figure that represents more than a 3x expansion of Ethereum’s current processing capacity and sets the stage for dramatically lower transaction fees for years to come.
The upgrade follows the successful deployment of Pectra in May 2025 and Fusaka in late 2025, both of which shipped on time and without major incident — a sharp contrast to Ethereum’s earlier track record of repeated delays.
What Is the Gas Limit and Why Does It Matter?
The gas limit is the ceiling on how much computational work Ethereum’s network can process per block. A higher limit means more transactions can be packed into each block, increasing throughput and reducing the backlog that drives fees up during periods of high demand.
Currently, Ethereum’s gas limit sits at around 60 million — a figure that forces significant congestion during peak periods and pushes transaction costs to double or triple digits in dollar terms. Glamsterdam’s 200 million floor changes that arithmetic entirely.
By tripling throughput at the base layer, the upgrade does two things simultaneously. First, it makes Layer 1 Ethereum competitive for a wider range of use cases that previously had to route through Layer 2 networks to remain economically viable. Second, it reduces pressure on Layer 2 infrastructure by expanding the amount of work that can be settled directly on the main chain.
Industry analysts at Phemex estimate that the combination of increased gas limits and related efficiency improvements will push Ethereum toward 10,000 transactions per second while cutting gas fees by approximately 78%.
What Else Is in Glamsterdam
The gas limit expansion is the headline, but Glamsterdam contains eight EIPs (Ethereum Improvement Proposals) that Vitalik Buterin outlined in late February 2026. The full set has not yet been publicly disclosed in final form, but confirmed components include:
- EIP-7702 extensions — Building on the account abstraction work from Pectra, Glamsterdam deepens smart account capabilities, allowing externally owned accounts to temporarily operate like smart contracts for the duration of a single transaction. This unlocks batch payments, sponsored gas, and social recovery without requiring users to migrate to new wallet infrastructure.
- 200M gas limit floor — Rather than leaving the gas limit to miner/validator discretion, the upgrade introduces a protocol-enforced floor that guarantees a minimum capacity level across the network.
- Validator performance improvements — Following the validator stake limit increase to 2,048 ETH in Pectra, Glamsterdam includes quality-of-life improvements that reduce computational overhead for node operators managing large validator sets.
- Blob throughput increases — The blob transaction mechanism introduced in Dencun (2024) gets another capacity expansion, further reducing costs for Layer 2 rollups to settle data on Ethereum L1.
The Competitive Pressure Behind the Upgrade
Ethereum is not upgrading in a vacuum. Solana’s on-chain metrics hit new highs in Q1 2026 — DEX volume, active addresses, and transaction counts all reached record levels even as SOL’s price underperformed relative to Bitcoin. The performance gap between Solana’s sub-second finality and Ethereum’s historically sluggish throughput has been a persistent talking point in the alt-L1 versus Ethereum debate.
Glamsterdam is the most direct answer Ethereum’s developer community has given to that critique. By expanding base-layer capacity while maintaining the security and decentralisation properties that make Ethereum the preferred settlement layer for institutional DeFi, the upgrade attempts to close the performance gap without sacrificing the qualities that differentiate Ethereum from faster but less battle-tested alternatives.
Ethereum’s Pectra upgrade, which introduced EIP-7702 smart accounts and expanded blob throughput, showed that the network can ship meaningful changes without destabilising the stack. That track record matters for the institutional cohort that has been steadily increasing ETH exposure through spot ETFs and treasury allocations.
What Glamsterdam Means for ETH’s Price Trajectory
The direct relationship between network upgrades and ETH price is notoriously difficult to quantify. The Merge drove an enormous amount of pre-event speculation that quickly reversed post-upgrade. But Glamsterdam’s fee reduction thesis is different in kind from proof-of-work elimination — it is fundamentally about expanding the market for Ethereum blockspace, which theoretically increases demand for ETH as gas.
If gas fees drop by 78% but transaction volume grows by more than 4x, the net ETH burned per day — the deflationary mechanic introduced in EIP-1559 — could actually increase despite lower per-transaction fees. That scenario would make Glamsterdam the first upgrade where fee reduction and ETH deflation are simultaneously achievable.
Devnet-4 testing is currently underway, and the upgrade is expected to go live in the first half of 2026, with a specific activation date likely confirmed at the upcoming Ethereum developer calls.
FAQ
Q: When does Glamsterdam go live on Ethereum mainnet?
A: Glamsterdam is scheduled for the first half of 2026. Devnet-4 is currently running, with the mainnet activation date expected to be confirmed at an upcoming All Core Developers call. The upgrade follows Pectra (May 2025) and Fusaka (late 2025), both of which launched on schedule.
Q: Will Glamsterdam make Ethereum cheaper to use?
A: Yes, significantly. The combination of a tripled gas limit floor and related efficiency improvements is projected to reduce average gas fees by approximately 78% compared to current levels. The impact will be most pronounced during high-congestion periods that currently push fees into the tens of dollars per transaction.
Q: How does Glamsterdam compare to Solana’s throughput?
A: At 10,000 TPS with Glamsterdam, Ethereum’s L1 throughput would approach Solana’s advertised peak capacity. However, Solana achieves high throughput partly through different decentralisation trade-offs. Ethereum’s upgrade maintains its full validator set and security model, making the comparison one of capability rather than equivalence.
