Glamsterdam upgrade

RSS

The Glamsterdam upgrade, originally set for Oct 26 2026 17:42:48 UTC on the Hoodi testnet (gas limit 200 M), was postponed on Oct 22 2026 after ChainSecurity identified 13 real‑world smart‑contract safety risks linked to the proposed EIP‑8037 (gas‑reserve for state creation) and EIP‑8038 (state‑access gas cost). The Ethereum Foundation confirmed that the testnet activation would not proceed and that a main‑net release is under review, with Dec 1, Dec 8, or Dec 9 on the horizon. Node operators should revert to earlier software versions or upgrade to clients that exclude the scheduled activation. The upgrade still aims to implement Enshrined Proposer‑Builder Separation (EIP‑7732), Block‑Level Access Lists (EIP‑7928), and other EIPs such as EIP‑8037 and EIP‑8038, pending safety verification. The Glamsterdam upgrade was tested on the Sepolia testnet.
