Glamsterdam On Track For December

The Ethereum Foundation published the September edition of its monthly all-Protocol sync, detailing the latest progress on the upcoming Glamsterdam and Hegotá upgrades. Glamsterdam testing is accelerating, with the team successfully deploying new benchmarking infrastructure that has reduced investigative loops from two weeks to a single day, while multi-client devnet testing continues to refine client resilience and circuit-breaker performance. The tentative schedule points toward a December mainnet upgrade, following public testnet deployments in October.

Meanwhile, Hegotá development has moved into its headliner phase with the launch of dedicated FOCIL and Frames devnets. Research efforts are now tackling the technical integration of these two mechanisms, while broader roadmap work focuses on a staged post-quantum migration plan. The Foundation also highlighted a new formal verification loop that leverages AI-driven assembly generation, demonstrating a path toward a verifiable Ethereum protocol stack that could fundamentally change how core client code is written and secured.
