Upcoming Ethereum network upgrade following Fusaka, aimed at raising gas limits and repricing gas costs on the main chain.
Ethereum's activation cap of 256 ETH per epoch had 1,282,776 ETH waiting an estimated 22 days, 6 hours on Oct. 15, according to Validator Queue. EIP-8061 would speed exits but keep that limit, so new stakers still idle for about three weeks.
Reality
Crypto's week has U.S. CPI due Oct 14 at a forecast 3.6% and PPI on Oct 15 at 5.3%, with $116.5 million of token unlocks. The 1.7-point gap between them is down from 2.0 on the prior readings, ahead of a Fed meeting where rates are expected to hold.
Reality
Ethereum's fee burn has offset 2.07% of 2026 issuance through Oct. 9, leaving supply about 0.64% higher, ethsupply.fyi data show. A larger gas limit would spread the roughly 2,992 ETH of daily burn needed to cancel issuance across more gas, so it slows supply growth only if blocks actually fill.

Ethereum's Glamsterdam upgrade lifts Sepolia's gas limit to 200 million from about 60 million, a load test for validators. Developers will use the result to size an upgrade that has no mainnet date, while user fees still turn on demand and on how Glamsterdam reprices state.

Curve Finance says Ethereum's Glamsterdam upgrade could make complex DeFi transactions more reliable during congestion. It told crypto.news the test is inclusion speed and fees under load, and that repriced state charges would raise gas for some actions.
Reality
Ethereum will activate Glamsterdam, likely its largest fork since the Merge according to a core developer, on the Sepolia testnet on Oct. 6. It reprices gas and lays groundwork for higher layer-1 gas limits, with no date yet for the Hoodi testnet or mainnet.

U.S. spot Ether ETFs lost a net $118 million in the week to Oct. 2, after taking in about $689.8 million the week before. The selling shrank as the week went on, and with ETH stuck under $2,800, Glamsterdam's Oct. 6 Sepolia activation is the dated event to watch.

Base's Cobalt upgrade went live on September 30 with Validity Transactions, swaps the chain holds privately until set conditions are met. It continues the push toward trading and tokenized assets that Base began in July with its B20 issuer standard.

Talks to reconcile Base's EIP-8130 with Ethereum's EIP-8141 broke down last week. Both chains will now ship their own native smart accounts. Derek Chiang, who co-authored Ethereum's proposal, says wallets carry the burden.
Reality
The Flashblocks cadence and the canonical block time are different numbers, and Base's cheaper-AA figure is measured on one operation on a network built to be thrown away. ERC-8403 moves account recovery into public state.
Reality
L2 pushback on EIP-8141 Frame Transactions keeps native AA out of Hegota's headliner slot for now, and the Ethereum Foundation has dropped its Poseidon hash for standard ones.
