Glamsterdam

Ethereum developers have merged a fix for a flaw in the upcoming Glamsterdam upgrade that could have credited ETH intended for new validators to builders instead. No losses have been reported, and client teams must now implement the revised deposit rules before the upgrade can move closer to mainnet.

Ethereum developers have delayed the Glamsterdam upgrade on the Hoodi test network after security researchers raised concerns about proposed gas accounting changes. The issue could affect how existing smart contracts handle failed transactions, while no new Hoodi activation date has been announced.

The crypto market advanced to $2.77T as Bitcoin traded near $83K, supported by a softer dollar, firmer equities and improved risk appetite. JPMorgan also added BTC to its long term return forecasts for the first time, while major industry updates from Ethereum, Visa, Mesh, SkyAI and Mt. Gox kept market attention active.

Ethereum’s Glamsterdam upgrade has lifted Sepolia’s processing allowance from about 60 million gas to nearly 200 million gas as developers test higher-capacity block design. Early sampled blocks used only 26% to 46% of the available allowance, while a short finality period showed strong testnet participation.

Ethereum developers released a late Prysm update to align validators with Sepolia’s planned 200 million gas limit under the Glamsterdam upgrade. The test is designed to show whether validators can reliably process blocks more than three times larger than Sepolia’s prior default.

Ethereum developers have confirmed key testing dates for the Glamsterdam upgrade while warning that disposable builder identities could disrupt Sepolia block production. The issue does not threaten mainnet funds, but it could complicate infrastructure testing before the upgrade moves closer to Ethereum activation.

Ethereum and Coinbase backed Base have stopped efforts to merge their next generation wallet standards after months of discussions. The decision leaves cross network wallets and apps preparing to support EIP 8141 on Ethereum and EIP 8130 on Base.
