# Ethereum Daily — October 1, 2026

# Ethereum Daily — October 1, 2026

This edition covers roughly the last 24–48 hours (September 29–October 1) and is diffed against [yesterday's post](https://julienberanger.com/eth-daily-2026-09-29).

**Roadmap.** Real movement here. Glamsterdam's Sepolia testnet run, still targeted for October 6 at 13:53 UTC, hit a round of newly surfaced issues: Devnet-9 testing produced unplanned non-finality that developers are still tracing to client compatibility and consensus-layer changes tied to enshrined proposer-builder separation (ePBS); EIP-8037's state-gas accounting showed edge cases in nested execution calls, prompting revised repayment logic; and EIP-7928 (Block-Level Access Lists) ran into a compatibility snag with legacy zero-nonce accounts that still hold storage, which a new companion proposal, EIP-8253, is meant to patch. Separately, developers flagged a builder-attack vector in ePBS on the September 17 dev call: because Sepolia test ETH is free, an attacker could spin up thousands of fake builders, win block auctions with inflated bids, and then withhold payloads — potentially stalling the testnet. Client teams had a September 29 deadline to ship Sepolia-ready software, leaving only a compressed seven-day security review versus Ethereum's usual fourteen. Devnet-11 is the next checkpoint before Sepolia goes live. October 6 "is not guaranteed," and mainnet remains a Q4 2026 target with no firm date.

**Governance.** No major new development since yesterday.

**Institutional and corporate adoption.** Chainlink unveiled Fulcrum, an institutional financing platform that coordinates repurchase (repo) transactions across public and private chains, at Sibos 2026 — where co-founder Sergey Nazarov is presenting alongside major banks. It's aimed at pulling more institutional repo and financing flow onto crypto rails, including Ethereum-based infrastructure. No fresh corporate ETH-treasury purchases surfaced in the last day.

**Stats.** ETH is trading around **$2,680–$2,688**, roughly flat to up about 0.4% on the day, still capped below resistance near $2,825–$3,000, with the 200-day EMA support sitting at $2,272. Derivatives positioning keeps unwinding: futures open interest fell to **12.49 million ETH**, the lowest since March 1, down roughly 1.46 million ETH since early July even as price has held up. ETF flows flipped negative: after a $17.1M inflow on September 28, spot ETH ETFs posted a $2.8M net outflow on September 29 — BlackRock's ETHA led exits at $8.94M, partly offset by Grayscale's Ethereum Mini Trust at +$12.83M — snapping the seven-day inflow streak. Outflows then widened sharply on September 30 to **$59.6M**, led by Fidelity's FETH (~$26.6M) and Grayscale's newer ETH fund (~$25.5M): two straight down days after a strong September. Macro backdrop: August core PCE inflation cooled to 3.4% YoY, below the 3.7% forecast, which markets read as mildly dovish, though it hasn't yet pulled ETF flows back positive. Broader DeFi market cap ticked up 0.6% to $88.6B.
