eip-8037

The Ethereum Foundation published a blog, reminding contract developers and auditors to check whether their projects rely on 8 Gas billing assumptions, which will no longer hold due to the adjustments in Gas charging methods in Glamsterdam with EIP-8037 and EIP-8038. The Ethereum Foundation has established a code repository that provides explanations, examples, and keywords for self-checking related to each assumption. Affected projects can contact the team via email.The team is collaborating with several auditing companies and conducting internal audits, but it cannot cover all projects on Ethereum and their on-chain and off-chain code. The Ethereum Foundation announced on October 23 that it has postponed the Glamsterdam upgrade originally scheduled to be activated on the Hoodi testnet, with a new activation time yet to be determined. Ethereum Foundation researcher Toni Wahrstätter stated on October 26 that the reason for the delay was a report from ChainSecurity that revealed issues with EIP-8037 when interacting with certain contracts, and its impact is now largely understood.

Due to the ChainSecurity report revealing compatibility and security issues with EIP-8037 and certain smart contracts, core developers decided last week to postpone the Hoodi testnet upgrade to Glamsterdam. The issues identified so far include: the remaining Gas during transaction execution may increase, leading to underflow in some Gas counting logic and triggering rollbacks, or causing code paths that should not be executed to be triggered, making the transaction appear successful. Additionally, some contracts may underestimate usage due to the inability to correctly calculate Gas consumption during calls.ChainSecurity previously stated that 13 real cases have been identified and they are responsibly disclosing this information to the affected projects. Toni Wahrstätter mentioned that this week they will further investigate the relevant contracts and assess subsequent solutions, which may require collaboration among application developers, core developers, auditors, and node operators. In the worst-case scenario, adjustments to the protocol specifications may be necessary. He reminded application developers and auditors to check the compatibility of contracts with EIP-8037 and EIP-8038 and to report issues in a timely manner.

On October 22, the smart contract security company ChainSecurity announced that the Glamsterdam hard fork on the Ethereum Hoodi testnet has been postponed. Researchers stated that security impacts have been found in existing contracts and identified 13 real cases, and they are currently conducting responsible disclosure with the affected projects. The announcement requests teams to review the contracts, and the Ethereum Foundation is assessing the scope of the impact; the announcement did not name the projects, provide contract addresses, or give an alternative fork date.The related issues involve contracts that continue execution after capturing failed external calls. Under the reviewed gas changes, the failure handler may complete execution, whereas it would previously roll back due to gas exhaustion. The caller can deliberately provide insufficient gas to complete the target operation, but enough to allow the outer contract to record a permanent failure, causing operations that could have been retried to lose their recovery path.The technical disclosure reviews EIP-8037 and EIP-8038 from the version specification dated October 13, where the gas examples described are for proposed execution behavior. The state-gas reservoir will be fully passed with the call, and forwarding restrictions apply to execution gas, with gasleft() only reporting the execution balance. According to the reviewed rules, clearing storage slots that start at zero at the beginning of a transaction can replenish up to 97,920 execution gas; intermediary contracts may also credit back the accounted state-creation fees upon REVERT and return them to the caller.

Ethereum co-founder Vitalik Buterin commented on the issue of Ethereum state storage, stating that even if users store data themselves, the blockchain only stores hashes, and transactions only include proofs, it still requires storage and updating of the data used to verify the proofs, and this data ultimately becomes almost as large as the state itself; Vitalik mentioned that there are solutions to the relevant issues, but they involve a large number of components and require trade-offs compared to the current Ethereum.Previously, DeFi content writer marilyn100x.eth stated that Ethereum has a state storage problem, where developers pay a one-time fee to write data, while nodes bear the long-term storage costs. However, EIP-8037 does not involve time-weighted rent or ongoing fees, but significantly increases the upfront gas costs for new contracts, accounts, and storage slots to control state growth during the scaling process.

The Ethereum Foundation disclosed the results of a recent interoperability meeting held by core developers in the Svalbard archipelago of Norway and updated the key technical progress for the next phase upgrade, Glamsterdam. During the meeting, multiple client teams collaborated on network scalability and execution layer optimization, making progress in several directions. Developers confirmed that based on the comprehensive results of ePBS, BAL optimization, and the EIP-8037 repricing mechanism, a consensus on the "trusted path" after Glamsterdam has been reached.In terms of the execution layer, ePBS (External Proposer Separation Architecture) has been stably running in the multi-client Glamsterdam-devnet, and the external block builder process has completed end-to-end testing, covering almost all client implementations. Meanwhile, EIP-8037 has been finalized, establishing the fixed cost_per_state_byte model, and complete repricing parameter output has been achieved in bal-devnet-6. The scalability direction Hegotá has also made progress. The FOCIL-related prototype has a runnable implementation, and the scope of account abstraction (AA) requirements has been defined, with the next phase entering the multi-client development network verification stage.Current development focus remains on the final implementation of Glamsterdam while advancing the Hegotá scalability design and subsequent Strawmap route evolution. The development network is online, and functionalities such as FOCIL are expected to continue deepening in the next phase of testing. At the organizational level, this interop meeting also marks the formal initiation of leadership structure adjustments within the Protocol Cluster. The new leaders include Will Corcoran, Kev Wedderburn, and Fredrik. Will Corcoran is responsible for zkVM proof and post-quantum consensus coordination, Kev Wedderburn leads zkEVM development, and Fredrik is in charge of protocol security and the Trillion Dollar Security project.Original Protocol Cluster leadership team members Barnabé Monnot and Tim Beiko will gradually step back from management roles, and Alex Stokes is entering a leave period. The foundation stated that during its term, the Protocol has completed modular advancement and facilitated the launch of the Fusaka upgrade (December 2025), introduced PeerDAS, and enhanced mainnet gas capacity.

The Ethereum Foundation published a summary of the Soldøgn Interop work, which has now basically completed the key goals of the Glamsterdam upgrade, including reaching consensus on the post-upgrade 200 million Gas Limit lower bound, achieving stable operation of the ePBS external Builder process, and finalizing the EIP-8037 Gas repricing parameters.The focus of the Glamsterdam upgrade is to enhance security by increasing the Gas Limit to expand Ethereum's throughput, while EIP-8037 will prevent state bloat caused by a high Gas Limit by raising the cost of state creation. The Ethereum Foundation also stated that most clients have completed stable operation on glamsterdam-devnet-2 and successfully tested the entire external Builder process. Additionally, substantial progress has been made on FOCIL, native account abstraction, and Hegotá upgrade-related features. In the coming weeks, core developers will continue to advance client hardening, testing improvements, and code merging, with final parameters to be publicly confirmed in the AllCoreDevs meeting.
