Ethereum’s Glamsterdam Upgrade Goes Live on Sepolia as ETH Slips

Ethereum’s Glamsterdam upgrade went live on the Sepolia testnet on Tuesday, a key rehearsal before any mainnet activation, according to Coincentral. The testnet launch landed alongside a sharp price move: ETH traded around $2,617 after dropping below $2,600, a fall of 2.98% on the day as of 06:37 UTC on October 7.

Coincentral reported that more than $400 million in long positions were liquidated within 20 minutes during the drop, while Coinglass data showed $15.3 million in ETH liquidations over 24 hours, $10.5 million of it from longs.

Key facts

• Glamsterdam went live on Sepolia on Tuesday at 1:53 pm UTC, announced by Ethereum community contributor Pooja Ranjan, per Cointelegraph.
• The gas limit rises from 60 million to 200 million under the upgrade, which combines the Amsterdam and Gloas packages and spans 18 core proposals plus 7 supporting ones.
• Spot Ethereum ETFs have posted six consecutive days of net outflows, with $207 million pulled over five days — the longest streak since June.
• Ethereum co-founder Vitalik Buterin said at the OKX NOW event on Tuesday that onchain apps will lean more on AI over the next two years, with bots handling much of the front-end activity.
• ETH’s RSI sits above 50, and the MVRV Ratio climbed from 1.4% to 3.5%, according to Coincentral.

What the upgrade changes

Coincentral described Glamsterdam as covering changes to how the network handles blocks and data. Cointelegraph reported that the Ethereum Foundation’s Sept. 28 blog post framed it around enshrined proposer-builder separation, block-level access lists and gas-pricing changes that better reflect execution cost. Cryptobriefing added that the upgrade realigns gas costs with resource usage and is meant to test the network’s capacity without affecting mainnet.

EIP-7732, the ePBS change, separates block proposers from builders on Ethereum’s consensus protocol and separates consensus validation from execution validation, giving validators more time to check execution payloads. EIP-7928 introduces enforced block-level access lists recording accounts and storage touched during a block so clients can read state and validate transactions in parallel. Cointelegraph noted the Ethereum Foundation set a 200 million gas limit floor for Glamsterdam in a May blog post.

ETF outflows and on-chain signals

The ETF picture has been weak. Lookonchain data cited by Coincentral showed Ethereum ETFs at -21,432 ETH (-$58.29 million) on a one-day basis and -79,193 ETH (-$215.37 million) over seven days as of Oct. 6. Coincentral read those flows as early buyers taking profits after ETH climbed from $2,400 to $2,800 in late September.

The technical picture is mixed. ETH still holds above its 20-, 50- and 100-day moving averages, with resistance near $2,781, $3,075 and $3,260 and support at the 20-day average near $2,656, then $2,631, $2,558 and the 50-day at $2,500. Coincentral noted analysts comparing the setup to April-May 2025, when ETH bottomed near $1,400 before rallying to a new all-time high after the Pectra upgrade, and said a similar pattern could play out if the $2,400 floor holds.

Why it matters

Sepolia is one of the final major rehearsals before Glamsterdam reaches mainnet, so a clean run matters for the layer-1 scaling roadmap that follows Fusaka. The timing is awkward for holders: the testnet milestone arrived in the same window as six straight days of ETF outflows and the largest short-term liquidation event Coincentral described. A successful testnet run keeps the upgrade on track; a technical problem would push the schedule and leave Ethereum on its current gas limit. The Competing framing is worth noting — Coincentral treats the milestone as already achieved while Cryptobriefing, writing before activation, framed it as poised to occur.

What to watch

Cointelegraph reported that after the Sepolia launch, developers will set Glamsterdam’s activation date on the Hoodi testnet and only then fix the mainnet date. Following mainnet activation, developers move to Hegotá, for which 66 proposals were under review in August as part of scoping, with several aimed at adding privacy features to the protocol.

The price levels Coincentral flagged — the $2,400 floor and the $3,400 upside — remain the reference points traders are watching. This is not financial advice; crypto markets are volatile and uncertain, and price predictions should not be treated as guaranteed outcomes.
