Ethereum has scheduled the Glamsterdam upgrade on Sepolia for Oct. 6. The release brings proposer-builder separation, block-level access lists and revised gas pricing, while the mainnet date remains unset.

Market context is cautious: total crypto market cap is down 1.7% over 24h, BTC dominance is 58.8%, ETH dominance 11.6%. ETF inflows cooled about 80% from Friday, with $64.8M combined across BTC, ETH, SOL and XRP funds on Monday.

Observation: testnet scheduling is a process signal, not a market catalyst yet. Interpretation: with risk appetite muted and yields elevated, Glamsterdam’s impact will depend on whether the upgrade changes fee dynamics and builder economics on mainnet. For now, the takeaway is simple: watch Sepolia execution and any follow-on guidance for mainnet timing.
