Ethereum Glamsterdam: What Developers Tested at Soldøgn

The article covers Ethereum’s Glamsterdam devnet stress-testing during the Soldøgn sprint, where client teams, builders, and protocol researchers pushed high transaction loads and builder bidding behavior to expose bugs before public testnets and mainnet. Glamsterdam-devnet-7 reportedly held up under heavier load, but builder issues emerged: Geth Builder and Nethermine were not consistently winning bids, highlighting integration and competitiveness risks in the MEV/block-building pipeline. The sprint also focused on gas semantics, including a proposed rename from “regular gas” to “execution gas” under EIP-8037, and on final repricing values that must be settled before DevNet-8. Teams are targeting early August for DevNet-8, which will require mandatory EIP-8070 engine API changes. Overall, the piece is constructive for Ethereum infrastructure but flags near-term implementation churn for wallets, rollups, builders, and node operators.
