Ethereum Glamsterdam Upgrade Delayed for Smart Contract Review

TLDR: The Ethereum Glamsterdam upgrade will miss its October 26 Hoodi activation as developers review EIP-8037 interactions with mainnet contracts. The postponement also removes the scheduled increase in Hoodi’s gas limit to 200 million, with no replacement activation date announced. EIP-8037 changes the cost of creating permanent blockchain data and separates that accounting from execution to manage database growth. Hoodi node and validator operators must check revised client guidance before October 26, while ETH holders do not need to take action. The Ethereum Foundation has postponed the Ethereum Glamsterdam upgrade on the Hoodi testnet, previously scheduled for October 26, 2026.
