Ethereum Glamsterdam Upgrade Reaches Testing Milestone, Gas Limit Target Set to 200 Million

According to the Ethereum Foundation's May 2026 Protocol Cluster update, developers announced major milestones for the Glamsterdam upgrade, with the multi-client development network now live and key components including enshrined proposer-builder separation (ePBS) and EIP-8037 progressing toward deployment readiness. The upgrade, expected to follow the Fusaka upgrade from late 2025, targets Layer-1 scalability improvements and MEV infrastructure formalization.

Developers established a post-Glamsterdam gas limit floor target of 200 million gas, substantially above Ethereum's current capacity of roughly 60 million gas. EIP-8037 introduces a fixed pricing model for state storage designed to keep annual state growth near 60 GiB even under larger block sizes. Several major features including FOCIL, Verkle Trees and expanded account abstraction have been shifted to the later Hegotá upgrade cycle to manage implementation complexity.
