Ethereum delays Glamsterdam’s Hoodi fork over gas-repricing risks

Ethereum’s All Core Developers have delayed the Glamsterdam hardfork process and will not fork the Hoodi testnet until teams resolve contract risks linked to two proposed gas-pricing changes.

The Ethereum Foundation said on 6 November that ChainSecurity found projects which could become vulnerable after Glamsterdam because they rely on assumptions that EIP-8037 and EIP-8038 would break. The proposals change how gas is charged for certain operations and for state.

All Core Developers therefore decided to delay the hardfork process and not activate Glamsterdam on Hoodi until the issues are resolved. Work on the later Hegota upgrade continues in parallel, according to the Foundation.

This is a risk discovered during testnet work, not evidence that Ethereum mainnet has newly failed. Developers and auditors are being asked to check eight affected invariants in their own on-chain and off-chain code and report projects that need attention.

The Foundation’s earlier testing note said most projects checked were unaffected and that many flagged cases could be addressed by raising gas limits. No revised Hoodi date has been announced, so the Royal Pond watchlist remains marked delayed.
