Glamsterdam Upgrade Set for Oct 6: Ethereum Developers Confirm Readiness Test
Ethereum's major upgrade, Glamsterdam, is scheduled for activation on the Sepolia test network on October 6, 2026. This upgrade changes both the consensus and execution layers of the protocol.
The current state of the client software requires developers to test on pre-release versions and devnets, with a key test (Devnet-11) starting September 14 to confirm readiness.
User preparation is crucial for those staking their own ETH. They should monitor client updates and ensure both execution and consensus clients are updated before the fork.
