Ethereum developers postponed the Glamsterdam upgrade on the Hoodi testnet after flagging 13 security risks tied to existing smart contracts.

The Glamsterdam upgrade has launched on Ethereum's Sepolia testnet, one of the last major rehearsals before it reaches the main network.

The zero-knowledge system lets users fund an Ethereum vault and authorize spending without tying their identity to individual API requests.

The Tom Lee-linked treasury company now holds more than 4.9% of ether's circulating supply, with total crypto, cash and other investments at $17.2 billion.
In a September 27 blog essay, Ethereum's co-founder said work after next year's upgrade will center on advanced cryptography and quantum-safe designs.

The company disclosed 5,983,940 ETH, 212 BTC and $714 million in cash and securities, putting the combined value of its holdings at $17.1 billion.

The network behind ONE will move to Ethereum, urging users to exit contracts by Sept. 10.

Initial $10.36B inflow reflects existing Grayscale assets migrating, not fresh buying.
Chinese mining pool founder reverses bearish stance, puts remaining funds into ETH.

Grayscale will sell staking rewards at least quarterly for ETHE, GSOL and GAVA, funding cash distributions.
Sygnum analyst says the 43-day wait for Ethereum staking is driven by protocol mechanics, not just investor demand.

Corporate miner Bitmine adds to its Ethereum treasury, reaching 5.7 million ETH.

A newly created Ethereum wallet has accumulated more than $28 million worth of ETH, on-chain data shows.

Calls to tax staking rewards or seek funding from large holders for initiatives like EthLabs are rekindling community tensions.

ConsenSys founder argues Ethereum's evolution aligns with permissionless infrastructure for global finance.

Bitmine buys 126,971 ETH worth $214M, its largest purchase of 2026, as Tom Lee dismisses market selloff.

On-chain data reveals a large holder sold $188M before the crash and repurchased at lower prices.

Consensys CEO Joe Lubin says recent Ethereum Foundation staff reductions and departures do not signal a crisis, but indicate a needed shift in focus.
