Woofun AI reports that the Ethereum Foundation has issued a critical warning to L1 contract maintainers regarding impending gas repricing mechanisms tied to the Glamsterdam upgrade, specifically driven by EIP‑8037 and EIP‑8038.

Scheduled for Q4 2026, with key milestones marked by August 25, 2026, the upgrade targets a tiny group of contracts identified through historical mainnet activity simulations. The Foundation has initiated direct outreach to affected builders, noting that while the vast majority of code remains stable, specific legacy implementations risk functional degradation without intervention.

Structurally, the update imposes new costs for creating and accessing state, a necessary correction given that Ethereum's state has grown significantly since the Berlin fork in 2021.

Woofun AI data shows that these adjustments align gas charges with actual computational work, addressing inefficiencies accumulated over years of network expansion.

The technical overhaul supports a performance target enabling roughly a 3x increase in base throughput, yet contracts relying on hardcoded gas values or outdated assumptions face immediate obsolescence risks. Increasing the gas limit resolves most highlighted concerns, but developers maintaining sensitive contracts are urged to review their implementations promptly to prevent breakage.

Glamsterdam merges the Amsterdam execution layer upgrade with the Gloas consensus layer upgrade, forming a coordinated push following the Fusaka upgrade. This reorganization of transaction processing and database management is expected to pave the way for more efficient L1 operations, marking a definitive shift in network scalability.
