The Ethereum Foundation has scheduled the Glamsterdam upgrade to activate on the Sepolia testnet on October 6, 2026. This technical rollout focuses on increasing Layer 1 throughput and adjusting gas accounting models.
Why it matters
The upgrade introduces proposer-builder separation and block-level access lists, which are designed to improve network scalability. These structural adjustments aim to manage resource usage more efficiently across the Ethereum ecosystem.
The upgrade will take place at epoch 353,024 on the Sepolia testnet, targeting improved gas accounting. Meanwhile, ETH futures open interest reached $3.12 billion on Hyperliquid, outpacing the $2.81 billion held in BTC futures.
The players
Ethereum Foundation
This is a non-profit organization that supports the development and growth of the Ethereum network.
Hyperliquid

Market Dynamics
The transition to the Glamsterdam upgrade reflects a broader industry trend toward modularity and improved block-level efficiency in decentralized finance. This development follows the Ethereum Foundation's established roadmap for scaling network performance while preparing for future security standards.
Traders and investors should note the shifting open interest metrics on platforms like Hyperliquid, where ETH futures recently surpassed BTC figures. While the testnet upgrade primarily concerns developers, changes in gas accounting and throughput can eventually influence transaction costs and market demand for ETH.
The takeaway
The Glamsterdam upgrade demonstrates a commitment to refining network performance through technical adjustments like proposer-builder separation. Market participants continue to watch these structural updates closely as they impact Ethereum's position relative to other digital assets.
