Ethereum Sellers Go Quiet as the Glamsterdam Countdown Begins

Ethereum rolls out hard forks on public testnets such as Hoodi before touching mainnet, a practice that caught problems ahead of Dencun in 2024 and Pectra in 2025. Glamsterdam, the next scheduled upgrade, was due on Hoodi on October 26, 2026 at epoch 132,352. That activation is now the one being pulled back, with EIP-8037's gas-accounting logic under fresh review for how it touches contracts already live on mainnet.

Node operators running Hoodi must now switch to client software that strips out the scheduled fork, undoing configuration they had already set for the October 26 activation. Developers lose the public test window they were counting on to validate EIP-8037 before mainnet, and with no new Hoodi date set, there is also no trigger point for scheduling Glamsterdam on mainnet. Projects building around the proposal's gas changes are left waiting without a timeline.

A four-day-out cancellation over gas-accounting interactions with existing mainnet contracts is a sign the review process is doing its job, not that it is broken: catching a compatibility risk on a testnet is the entire point of running one. The trade-off is between shipping Glamsterdam's features on a predictable schedule and reopening audited code each time a new interaction surfaces, a tension Ethereum's multi-client, multi-testnet process has never fully resolved.

Watch for a revised Hoodi activation announcement specifying a new epoch and UTC time, which would restart the countdown to a mainnet trigger for Glamsterdam. Until core developers publish that date, the upgrade has no public test schedule and no mainnet target; the resolution of the EIP-8037 and gas-accounting review is the specific gate that determines when, or whether, that announcement comes.
