Overview
- The Ethereum Foundation warned that wallets, indexers and gas estimators that assume a single fixed gas ceiling will break and must be tested and updated.
- The fork implements EIP-8037, which charges a runtime per-byte state fee for account creation, code deposits and new storage instead of bundling those costs into the old flat model.
- The Glamsterdam rules are scheduled to activate on the Platåberget testnet on Aug. 20, giving developers a longer-lived public environment to run validator and builder deposit workflows.
- The upgrade also enshrines proposer-builder separation and adds Block-Level Access Lists to change how blocks are built, give nodes advance info about accessed state, and enable parallel processing.
- Earlier parameter work showed state-creating actions could become materially more expensive—new account creation roughly 8.5 times and contract deployment near tenfold under reported scenarios—which could raise failure rates for transfers that still use a 21,000 gas hardcode and raise costs for apps that create state.
