Ethereum’s core developers have agreed on a 200 million gas limit floor for the upcoming Glamsterdam hard fork — a 3.3x increase from the current 60 million cap — in what may be the single most consequential network change since The Merge.
The decision, confirmed in the latest All Core Developers call and reported by The Defiant and Crypto Briefing on May 4, locks in a throughput expansion that developers say could keep base fees pinned near zero for “multiple years” under normal load conditions.
What Is the Glamsterdam Upgrade?
Glamsterdam is the name for Ethereum’s next major hard fork, targeting H1 2026. It builds on Pectra — which went live last month with EIP-7702 smart accounts — by adding a set of changes focused on raw network throughput, validator efficiency, and MEV reduction.
The key components include:
- ePBS (enshrined Proposer-Builder Separation): Moves block building on-chain, reducing the outsized influence of MEV bots and making the validator set more profitable and fair
- Block-Level Access Lists: Allow more efficient parallelization of transaction processing
- EIP-8037 Gas Repricings: Adjust the computational cost of specific opcodes to better reflect actual validator work
- 200M Gas Limit Floor: A hard floor, not a soft target — meaning validators will not be able to drop below this level, locking in minimum throughput
Together, these changes are designed to enable sustained high-throughput at low fee levels.
Why 200M Gas Matters
To understand the significance, consider what the current 60M gas limit means in practice. Each Ethereum block can only process a fixed amount of computation. When demand exceeds capacity, users bid gas fees up to prioritize their transactions. During peak DeFi activity, gas fees for simple token swaps have historically hit $50–$200. NFT mints during hot launches have triggered $300+ fees.
At 200M gas, Ethereum can process more than three times as many operations per block. That doesn’t mean fees go to zero — it means the threshold at which fee spikes occur is dramatically higher. Developers expect that under current load projections, L1 base fees should remain in the sub-$1 range for routine transactions for the foreseeable future.
“This is a 3x of L1 execution capacity,” wrote Ethereum researcher Justin Drake on X. “With expectation of further doubling soon after that. The era of $50 gas fees is structurally over.”
Impact on Ethereum’s Layer 2 Ecosystem
One counterintuitive question: does cheaper L1 hurt Layer 2 networks like Arbitrum, Optimism, and Base — which have built entire ecosystems around the premise that L1 is too expensive?
The short answer is no, for two reasons. First, L2s benefit from cheaper L1 calldata costs for their own settlement transactions, reducing their operating overhead. Second, a more capable L1 tends to grow the overall Ethereum user base, which lifts all boats.
However, some L2 analysts have noted that Glamsterdam does narrow the fee-advantage gap between L1 and L2. Arbitrum and Optimism may face more price competition for simple use cases.
What This Means for ETH Price
Historically, major Ethereum upgrades have had a complicated relationship with price. The Merge in 2022 was “buy the rumor, sell the news.” Pectra last month saw a modest post-launch rally that faded within days.
Glamsterdam is different in one key respect: it addresses what has long been Ethereum’s primary competitive liability versus Solana and Avalanche — high fees under load. If the upgrade executes cleanly and base fees demonstrably drop, it removes a major talking point for ETH competitors.
ETH is currently trading around $2,340, down slightly from pre-week highs. Options markets show moderate bullish positioning for the 30-60 day window around the expected Glamsterdam launch date.
Timeline and What to Watch
Glamsterdam does not yet have a confirmed mainnet launch date, but developers have indicated a Q2 2026 target. The 200M gas limit floor decision is a major milestone — resolving one of the last significant design debates.
Key dates to watch:
– Next ACD call: Technical finalization of remaining EIPs
– Devnet launch: Public testing phase expected within weeks
– Mainnet target: Q2 2026, pending devnet results
For traders, the key signal to watch is whether the devnet launch triggers renewed institutional interest in ETH — particularly from funds that have been underweight Ethereum relative to Bitcoin in their crypto allocations.
FAQ
What is the Ethereum Glamsterdam upgrade?
Glamsterdam is Ethereum’s next major hard fork, targeting H1 2026. It introduces a 200M gas limit floor (up from 60M), ePBS for fairer block building, and several EIP repricings designed to dramatically increase network throughput and keep fees near zero under normal load.
How will Glamsterdam affect Ethereum gas fees?
The 200M gas limit floor represents a 3.3x increase in per-block computation capacity. Developers expect this to keep L1 base fees below $1 for routine transactions for multiple years under current demand projections, effectively eliminating the high-fee problem that has historically driven users to Layer 2 networks.
When will Glamsterdam launch on mainnet?
Developers have targeted Q2 2026 for the Glamsterdam mainnet upgrade, pending successful devnet testing. No specific date has been confirmed. A devnet launch is expected within weeks following the recent gas limit decision.
