Ethereum Glamsterdam Upgrade Advances in Final Devnet Tests as ETH Holds Near $1,700

Ethereum's Glamsterdam upgrade entered final internal devnet testing on June 16-17 2026, validating all planned EIPs ahead of public testnets. The overhaul, Ethereum's largest since the Merge, follows the Fusaka upgrade of December 2025 and targets mainnet activation in the second half of 2026. Core changes include enshrined Proposer-Builder Separation (EIP-7732), Block-Level Access Lists (EIP-7928), gas repricing, and a proposed 200 million gas limit designed to cut fees up to 78.6% and reach 10,000 TPS. ETH trades near $1,700 after a 40%+ year-to-date decline, with long-term network improvements expected to support competitiveness versus other L1s.
