Hoodi fork delayed over Glamsterdam gas-repricing invariants
The Ethereum Foundation's Glamsterdam network upgrade activated on Sepolia on October 6, adding ePBS, block-level access lists, and gas repricing via EIP-8037 and EIP-8038, which rework gas charges for certain operations and for state. The Hoodi testnet activation remains postponed with no new date after Chainsecurity flagged projects that would be vulnerable post-Glamsterdam because they rely on invariants the EIPs break.
On November 6, EF developer Marius van der Wijden confirmed in a blog post that ACD decided to delay the hardfork process and not fork Hoodi until the issues are resolved. The EF published a repository of the eight broken invariants with examples and prompts, and is asking contract developers and auditors to check whether their projects rely on any of them, reporting to glamsterdam@ethereum.org.
- Details of the potential issues are available in the Chainsecurity blog post and a community-built repricing tool
- Breaking change for app developers: gas repricing removes the fixed maximum gas ceiling, so wallets, indexers, and gas estimators assuming a hardcapped limit must be updated
