Ethereum Delays Glamsterdam Hoodi Testnet Fork Over Gas Security Flaws

The delay matters less for the schedule slip than for what it reveals: the gas repricing bundled into Glamsterdam carries contract-level risk that surfaced only in external review, with ChainSecurity pointing to real-world cases rather than a theoretical edge. That puts smart-contract teams and tooling providers in the path of any eventual change, since the failure mode described affects deployed contracts, not just new code. With no replacement date set, the open question is whether the gas changes are narrowed or redesigned before the fork is rescheduled — and how much the review extends the broader upgrade timeline.
