Ethereum developers postpone Glamsterdam upgrade on Hoodi testnet

October 23, 2026

Ethereum core developers decided on the ACDE #248 call to postpone the Glamsterdam upgrade on the Hoodi testnet, which had been scheduled to activate on October 26, 2026. The delay allows further investigation into how EIP-8037 and EIP-8038 interact with existing mainnet contracts, with concerns centered on EIP-8037's gas-pricing changes and smart-contract compatibility.

No new activation date has been set for the testnet fork
Lido relayed the update to its community on X (post)
