> Thirteen real contract cases have been identified, and developers will review additional contracts this week.

Ethereum core developers have postponed the Glamsterdam upgrade on the Hoodi testnet after EIP-8037 raised compatibility and security concerns for smart contracts, delaying a test of the protocol change.

Reported problems center on how contracts handle gas during transaction execution. Remaining gas may increase in some cases, causing gas-counting logic to underflow and revert a transaction, or activate a code path that should not run while making the transaction appear successful. Some contracts may also underestimate gas use because they do not correctly calculate consumption during a call.

Thirteen real cases have been identified, and responsible disclosure is underway with affected projects. Developers will review additional contracts this week and assess possible fixes. The work may require application developers, core developers, auditors and node operators; in the worst case, the protocol specification could need changes.

The review will continue this week.
