EIP-8037/EIP-8038 Glamsterdam
- Published
- Updated
Ethereum developers have paused the Glamsterdam step on the Hoodi testnet after security reviews flagged eight smart-contract assumptions that could be broken by EIP-8037 and EIP-8038. The Ethereum Foundation has opened a review for developers and auditors while the mainnet timetable remains unset.

What it means
Smart-contract teams and auditors now have a concrete checklist: eight gas-related assumptions published by the Ethereum Foundation that projects must test their code against before the fork resumes. Contracts with fixed gas budgets or reserves, the pattern most findings involve, may behave differently after the upgrade even without any code change on their end. Until audits clear these cases, the Hoodi step stays paused and no mainnet date can be set, leaving deployment teams waiting.
A protocol that changes how gas is priced can quietly invalidate contracts that never asked to be touched, which is why several developers pushed back hard. The Curve Finance founder's public plea, 'please don't break the chain,' captures the real tension: optimizing gas accounting at the protocol layer collides with the promise that deployed, immutable contracts keep working as written. Ethereum has resolved this before through delay and patching, not through forcing contracts to adapt.
The next checkpoint is whether audits against the eight published invariants clear the flagged projects, at which point developers can resume the Hoodi testnet step that was paused on November 6. A clean pass would let core developers set a mainnet activation date for Glamsterdam; fresh vulnerabilities would extend the pause further and could force changes to EIP-8037 or EIP-8038 themselves before any date is named.
Market reaction i
Ethereum fell 0.4% in the 4 hours after the first headline, after rising 0.4% in the 2 hours before.
47 prices, one every 30 minutes · The move was larger before the first headline than after: an observation, not an explanation. The market also moves on things nobody publishes.
