Ethereum put Glamsterdam’s Hoodi fork on hold. What did auditors find?

Ethereum developers have put Glamsterdam’s Hoodi testnet fork on hold while they work through findings about how applications behave when a transaction runs low on gas. The upgrade changes the way the network charges for some operations that touch or expand its state, and auditors found that even contracts written before the upgrade can behave differently under the proposed rules. Summary Ethereum developers had targeted 26 October for the Hoodi fork before postponing it. A 6 November developer update kept the fork on hold while the teams addressed issues raised during review. Two proposals, EIP-8037 and EIP-8038, affect the cost of creating state and accessing existing state. The change can alter how much gas a contract has left at a particular point in execution. ChainSecurity identified cases where a call can fail and the contract that made it can still complete its failure handler. Under the earlier gas rules, the same path might have caused the outer transaction to revert. Developers are checking assumptions across client implementations and existing contracts. ChainSecurity, Dedaub and internal reviewers contributed to the review, according to the Ethereum Foundation update. ...
