The Ethereum Foundation has published guidance on EIP-8037/EIP-8038, noting that ChainSecurity found some projects could break after upgrading.
According to an announcement from the Ethereum Foundation on November 6, 2026, the two EIPs change how gas is charged for certain operations and how state gas is accounted for. During reviews over the past few weeks, ChainSecurity found that changes introduced by these EIPs would break certain invariants that a small number of projects rely on, creating a risk of vulnerabilities after upgrading.
· The changes affect projects that rely on these invariants, not all contracts; the announcement did not provide a project-by-project list.
· Both EIPs are still progressing as part of the Glamsterdam upgrade. Refer to the official announcement for the final timeline and details.
Do any of your contracts rely on fixed assumptions about state gas?
