Ethereum Glamsterdam Upgrade Delayed Again: No Launch Date as 8 Rules Break — What It Means for ETH at $2,140

Ethereum's biggest upgrade in years no longer has a launch date. On November 6, 2026, the Ethereum Foundation confirmed that core developers will not fork the Hoodi testnet — the final rehearsal before mainnet — until eight smart-contract rules broken by Glamsterdam's new gas pricing are fixed. One everyday operation, delegating an empty account, would jump from 25,000 gas to 235,606 gas: a 9.4x increase that could break wallets, relayers and contracts holding real user funds. ETH, already trading at $2,140 after a brutal weekend that saw it touch $2,060, now faces a second problem: the roadmap's most important upgrade is open-ended, with no replacement date for the testnet fork and no mainnet target at all.

This is not a hack, not a chain halt, and not a reason to panic-sell your ETH. It is something rarer in crypto: a delay caused by the safety process working exactly as designed. The bugs were caught on testnets, before a single dollar of mainnet funds was at risk. But the delay still matters — for developers, for ETH's price, and for anyone who believed Glamsterdam was weeks away. Here is what actually broke, what it means for your coins, and the three scenarios that decide where ETH goes next.

What Just Happened: The November 6 Decision

On Friday, November 6, Ethereum Foundation developer Marius van der Wijden published an update that changed Glamsterdam's status overnight. The All Core Developers group — the engineers who decide when Ethereum upgrades ship — will not proceed with the Glamsterdam fork on the Hoodi testnet until problems found during testing are resolved. The post named no new date for Hoodi, and it set no mainnet target. As one analysis of the decision put it, this was the first time in Glamsterdam's cycle that core developers took the mainnet target off the roadmap entirely.

The decision followed an October 13 review by ChainSecurity, the smart-contract auditing firm, which found that two Ethereum Improvement Proposals at the heart of Glamsterdam — EIP-8037 and EIP-8038 — could break smart contracts that rely on fixed assumptions about gas costs. The Foundation is now working with ChainSecurity and Dedaub on the fix, has published a repository listing the eight invariants, and has opened a dedicated mailbox, [email protected], asking every team in the ecosystem to check its code privately and report exposure.

The important context: Glamsterdam had already slipped once. The Hoodi activation was originally scheduled for October 26, 2026, at 17:42:48 UTC. That slot was postponed on October 23, when the first security concerns surfaced — a delay we covered at the time. The November 6 post is broader and more serious: the whole fork process is now paused pending a formal fix, and the Foundation says its preferred path is changing the two EIPs themselves rather than dropping them. Work on Hegota, the upgrade planned after Glamsterdam, continues in parallel.

The Two EIPs at the Center: EIP-8037 and EIP-8038 Explained in Plain English

To understand what broke, you need to understand what Glamsterdam is trying to do. It is the biggest reshape of Ethereum's fee mechanics since EIP-1559, the 2021 upgrade that introduced fee burning. The goal is to price the network's resources more honestly: today, some operations are far cheaper than the burden they place on the network, and the upgrade rebalances those costs.

EIP-8037 introduces state-growth metering. In plain English, it creates a separate gas reservoir for operations that make Ethereum's state bigger — creating new accounts, adding storage slots, deploying code — and meters that growth separately from ordinary execution. Once the reservoir is exhausted, state-touching operations are repriced to punitive levels rather than simply reverting. EIP-8038 reprices cold access: the cost of the first touch of an account or storage slot that has not been used recently. Together, the two proposals change what some of the most common operations on Ethereum actually cost.

That is where the eight broken invariants come in. An invariant is an assumption developers bake into their code — for example, "this operation will always cost roughly X gas." Thousands of deployed contracts were written against the old gas schedule. If a contract assumes a call costs 25,000 gas and the upgrade makes it cost 235,606, the contract does not just get more expensive. It can fail outright, run out of gas mid-transaction, or behave differently in ways its authors never anticipated. ChainSecurity's October review found real-world projects exposed in exactly this way.

The Sepolia testnet activation on October 6, 2026, held without incident — the new gas rules ran fine on a test network. But Sepolia is a rehearsal with test tokens. Hoodi is the final dress rehearsal before mainnet, and the decision was that it does not happen until the compatibility problem has a real fix.

The 25,000 to 235,606 Number That Explains Everything

One example in the Foundation's material captures the scale of the problem better than any abstract explanation. Under Glamsterdam's proposed rules, delegating an empty account — an operation used by smart wallets and account-abstraction systems — would cost 235,606 gas, up from 25,000 gas today. That is a 9.4x increase on a single, routine operation.

Why does that matter to someone who just holds ETH and never writes a line of code? Because smart wallets are exactly the products millions of new users are being onboarded with, and relayers — the services that submit transactions on users' behalf — budget their gas costs in advance. A 9.4x jump on a routine step means transactions that used to succeed could fail and services that priced their fees on the old schedule would suddenly be underwater. Multiply that across the eight broken invariants, and you get an upgrade that, shipped as-is, could have broken a meaningful slice of the applications people actually use.

The Foundation's response is the responsible one: pause, publish the full list of what breaks, ask every team to check, and fix the specifications before the fork moves forward. The full Glamsterdam explainer we published earlier covers the upgrade's other pieces, including ePBS and block-level access lists, which are not the source of this delay.

Timeline: How Glamsterdam Lost Its Launch Date

The delay did not arrive out of nowhere. It built up over a month of findings, each one narrowing the upgrade's path to mainnet. Here is the sequence that matters:

Date	What happened	What it meant
October 6, 2026	Glamsterdam activates on the Sepolia testnet	The new gas rules run cleanly in rehearsal; the upgrade looks on track
October 13, 2026	ChainSecurity publishes its review of EIP-8037 and EIP-8038	Eight broken invariants identified; real projects shown to be exposed
October 23, 2026	Hoodi testnet fork postponed	The planned October 26 activation is pulled; first public delay
November 6, 2026	Foundation post by Marius van der Wijden: no Hoodi fork until issues resolved	Whole fork process paused; no new Hoodi date; no mainnet target
November 9, 2026	ETH trades at $2,140 after touching $2,060	Market prices in the delay alongside the midterm sell-off and ETF outflows
Next milestones	Revised EIP specifications, confirmed fixes, then a new Hoodi date	No dates set; the next All Core Developers call is the event to watch

What Most People Get Wrong About the Delay

Every Ethereum upgrade delay produces the same wave of misunderstandings. Here is what the November 6 decision is — and what it is not.

Myth 1: Ethereum is broken or halted. Wrong. The network is running normally. The delay applies to a testnet fork, not to mainnet. No user funds are affected, and no mainnet exploit has been reported. The Foundation's own post is explicit that the concern is about how applications would behave after the upgrade, not about the chain today.

Myth 2: The delay means Glamsterdam is cancelled. Wrong. The upgrade is paused pending a fix, with the EIPs kept in the fork and Hegota work continuing. Ethereum has delayed upgrades before — and shipped them after the fixes landed. The responsible comparison is not a cancellation, it is a postponed launch.

Myth 3: This is the reason ETH fell to $2,060. Partly wrong. ETH did fall about 5% to a low of $2,060 over the weekend, but the bigger drivers were macro: Democrats winning both chambers of Congress in the US midterms, a hot October jobs report that pushed December Fed rate-hike odds toward 80%, and $365 million leaving US spot Ethereum ETFs in the week ending November 6. The Glamsterdam news added to the pressure, but it did not cause the sell-off on its own. Bitcoin fell to $73,708 at the same time, and Bitcoin has no Glamsterdam.

Myth 4: Developers should panic. Wrong — developers should audit. The Foundation published the eight invariants and a contact address precisely so teams can check their own exposure quietly, before anything ships. If your project touches gas assumptions, the time to look is now.

Myth 5: A delayed upgrade is bad for ETH's price long-term. Unproven. A rushed upgrade that breaks live contracts would be far worse for ETH than a delayed one. What the market is really pricing right now is uncertainty — and uncertainty ends the moment the Foundation names the fix and a new Hoodi date.

What It Means for ETH at $2,140

ETH is trading at $2,140 on Monday morning, down sharply from the $2,240 level it held just days ago. The weekend low of $2,060 was the weakest print since the summer, and the technical picture is fragile: analysts put the first support at $2,060–$2,100, the zone ETH must defend, and the first resistance at $2,229–$2,262, the level it must reclaim to turn the short-term trend around. The Crypto Fear and Greed Index sits at 28, deep in fear territory, and Ethereum traders lost $345 million in liquidations in a single night — more than Bitcoin traders lost in the same session.

The Glamsterdam delay lands on top of an already heavy tape. US spot Ethereum ETFs lost $365 million in the week ending November 6, and Bitcoin ETFs lost $1.28 billion in the same week, including $411.9 million on Friday alone. The October jobs report — 165,000 new jobs against roughly 65,000 expected, with unemployment falling to 4.1% — pushed market-implied odds of a December Federal Reserve rate hike toward 80%. And the next big event is hours away: the October Consumer Price Index lands Tuesday, November 10, at 8:30 AM ET, with core inflation expected at +0.2% month over month. That report, not Glamsterdam, is what decides whether ETH holds $2,100 or tests $2,000.

Here are the three scenarios that decide ETH's next move. They are predictions, labelled as such, not guarantees.

Scenario	Trigger	ETH target	What to watch
Bull — relief rally	CPI comes in cool, Fed hike odds fall, ETF outflows slow	$2,450	Reclaim of $2,229–$2,262 resistance, then $2,450; Glamsterdam fix announced
Base — chop	CPI in line, market digests the delay, no new shock	$2,060–$2,260 range	ETH holds $2,060–$2,100 support and grinds sideways into the next All Core Developers call
Bear — breakdown	Hot CPI, hike odds rise further, $2,060 support fails	$2,000, then $1,950	Daily close below $2,060 opens $2,000; a further leg down targets the $1,950 zone

The Glamsterdam angle matters most in the bull case. A credible fix and a new Hoodi date would remove the uncertainty premium sitting on ETH right now, and it would arrive as a positive catalyst in a market starved of good news. In the bear case, the delay is a footnote — macro would be doing the damage. The base case is the most likely in the near term: ETH chops between $2,060 and $2,260 while traders wait for Tuesday's CPI print and the next word from the core developers.

One longer-term point is worth making. Glamsterdam's gas repricing, once fixed, is designed to make Ethereum cheaper and more predictable to use. A delay of weeks or even a couple of months does not change that destination, and ETH's structural story has not changed: the network still settles the majority of stablecoin and DeFi activity. If you are trying to decide whether the delay changes your thesis, the honest answer is that it changes the timing, not the direction.

What ETH Holders Should Do Now

If you hold ETH, the delay asks for a checklist, not a panic trade. Run through these five points before Tuesday's CPI report:

• Check your wallet type. If you use a smart wallet or account-abstraction wallet, you are in the category most affected by the gas changes. Nothing breaks today — the upgrade is not live — but bookmark your wallet provider's announcements for when a new Hoodi date is set.
• Do not move funds because of the delay. There is no mainnet risk from Glamsterdam right now. Moving coins in a fear-driven market usually costs more in fees and slippage than it saves in risk. Our guide to storing crypto safely covers the cold-storage basics that matter far more than any upgrade timeline.
• Watch $2,060 and $2,262. Those are the two levels that decide the next move. A daily close below $2,060 is the breakdown signal; a reclaim of $2,262 is the first sign of stabilisation.
• Watch Tuesday 8:30 AM ET. The October CPI report is the week's main event. A cool print helps everything, including ETH. A hot print hurts everything, including ETH. Glamsterdam will not be the driver that day.
• Watch the next All Core Developers call. That is where the fix and the new Hoodi date will first appear. A credible new date is the single most positive catalyst available for ETH right now — and it will come from the Foundation's blog, not from social media rumours.

What Developers Should Do Now

If you build on Ethereum, the Foundation's message is direct: audit your code against the eight published invariants now, while the fork is paused. Check any place your contracts assume a fixed gas cost, any logic that depends on how much gas remains after an external call, and any relayer flow that budgets gas in advance. Teams that find exposure are asked to report it privately to [email protected] rather than in public issues, so fixes can be coordinated before the specifications are finalised.

FAQs

What is the Glamsterdam upgrade?

Glamsterdam is Ethereum's next major protocol upgrade, focused on repricing how the network charges for gas — particularly the cost of growing the network's state and accessing stored data. It includes EIP-8037 (state-growth metering) and EIP-8038 (cold-access repricing), alongside other changes such as ePBS and block-level access lists. It is described as the biggest reshape of Ethereum's fee mechanics since EIP-1559 in 2021.

Why was Glamsterdam delayed?

Security firm ChainSecurity found in an October 13 review that EIP-8037 and EIP-8038 break eight smart-contract invariants — assumptions that deployed contracts rely on about gas costs. On November 6, the Ethereum Foundation confirmed that core developers will not fork the Hoodi testnet until the issues are fixed, and no new date has been set.

Does the delay affect my ETH or my funds?

No. The delay applies to a testnet fork, not to mainnet. The Ethereum network is running normally, no mainnet exploit has been reported, and no user funds are at risk from Glamsterdam today. The pause exists precisely to make sure funds stay safe when the upgrade eventually ships.

When will Glamsterdam launch now?

There is no date. The November 6 post set no replacement Hoodi date and no mainnet target. The next milestones are revised EIP specifications, confirmed fixes for the affected cases, and then a new Hoodi fork date, most likely announced after the next All Core Developers call.

Is ETH a good buy at $2,140 after the delay?

That depends on your time horizon and risk tolerance, and this article is not financial advice. Short-term, ETH is driven by Tuesday's CPI report and Fed rate expectations, not by Glamsterdam. Long-term, the delay changes the upgrade's timing, not its purpose — cheaper, more predictable gas. The key levels are $2,060 support below and $2,262 resistance above. Anyone considering a purchase should read a full guide to how crypto ETFs work and understand the risks before deciding.

What is Hegota, and is it delayed too?

Hegota is the upgrade planned after Glamsterdam. The Foundation said explicitly that work on Hegota continues in parallel and is unaffected by the Glamsterdam pause. The fix for Glamsterdam's gas proposals will land before Hegota work merges in.

Conclusion

Ethereum just did something the crypto industry rarely gets credit for: it chose to be late rather than wrong. The Glamsterdam delay is frustrating for anyone who wanted a launch date, and it arrives at a bad moment — ETH at $2,140, ETFs bleeding, a CPI report hours away, and a market already in fear. But the alternative was shipping a gas repricing that could have broken live contracts, wallets and relayers, with real money on the line. The eight broken invariants, the 25,000-to-235,606 gas jump, and the open-ended timeline are all real problems — and they are all problems that were found before they could hurt anyone.

The trade for ETH holders is now simple to state and hard to time: Tuesday's CPI decides the next $200, while the Glamsterdam fix decides the next few months. Watch $2,060 and $2,262, watch the CPI print at 8:30 AM ET, and watch the Foundation's blog for the fix that puts Glamsterdam back on the calendar. The upgrade is delayed. It is not dead.
