Ethereum Delays Glamsterdam Hoodi Fork After EIP-8037 and EIP-8038 Risks Emerge
Ethereum's planned Glamsterdam fork on the Hoodi testnet has been delayed after security researchers identified potential compatibility risks involving EIP-8037 and EIP-8038, according to Wu Blockchain. The issues concern changes to gas behavior that could affect existing smart contracts, prompting developers to review whether the upgrade specification requires revisions.
Ethereum researcher Toni Wahrstätter said the delay followed findings from ChainSecurity, which identified risks associated with the two Ethereum Improvement Proposals (EIPs). The findings raise concerns about how certain contracts may behave under the proposed gas changes, including situations involving assumptions about gas consumption and the execution of failed sub-calls.
Compatibility Risks Under Review
One concern is that the gas changes could break contracts designed around the assumption that gas usage can only decrease. If those assumptions no longer hold under the proposed changes, affected contracts could encounter unexpected behavior.
A separate concern involves failed sub-calls, which markets could behave unexpectedly under the revised gas rules. These potential effects have made compatibility an important consideration as developers assess the planned testnet upgrade.
ChainSecurity has identified 13 real-world cases related to the risks. The cases provide concrete examples for developers to examine as they evaluate the potential consequences of implementing EIP-8037 and EIP-8038.
Developers Assess the Upgrade Specification
The delay gives developers an opportunity to review the findings and determine whether the current upgrade specification adequately addresses the identified risks. The review includes consideration of whether changes to the specification are necessary before the planned fork proceeds.
The issues involve the interaction between proposed gas changes and existing contract behavior. This makes it important to assess not only how the changes are intended to work, but also whether contracts relying on existing assumptions could encounter failures or unexpected execution outcomes.
The reported delay concerns the planned financial Glamsterdam fork on the Hoodi testnet. The available information does not specify a revised activation date or confirm that changes to EIP-8037 or EIP-8038 have been finalized.
According to Wu Blockchain, developers are still reviewing whether the upgrade specification needs to change following ChainSecurity's findings. The 13 real-world cases identified by ChainSecurity remain a key part of that assessment.
