Ethereum delays Glamsterdam test after security devs flag risk to existing contracts

Grade Bbearish AI signal$ETH

Ethereum developers have postponed the Glamsterdam upgrade on the Hoodi testnet after security researchers identified potential changes to how existing smart contracts handle failed transactions. The concerns center on EIP-8037 and EIP-8038, which could alter gas accounting and cause some contract operations to succeed or fail differently under the proposed rules; no replacement date has been announced. The delay could pressure short-term sentiment around ETH and Ethereum's upgrade timeline, although developers say the findings do not indicate that existing contracts are currently being exploited.

Bullish strength: 25/100

Developers postponed the upgrade to investigate potential smart-contract security risks before deployment.
The findings do not establish that a major production protocol is exploitable.
Glamsterdam previously completed its Sepolia testnet activation on October 6.

Bearish strength: 75/100

Security concerns forced the postponement of the planned Hoodi testnet upgrade.
No replacement date has been announced, and Ethereum mainnet activation remains unconfirmed.
Proposed gas-accounting changes could cause existing contracts to handle failed transactions differently.
Creating a new storage slot could require 110,020 gas under the described conditions, compared with 22,100 under the old rules.

Ethereum Delays Glamsterdam Testnet Activation Over EIP-8037 Risks

Ethereum has delayed activation of the Glamsterdam upgrade on the Hoodi testnet, which had been scheduled for October 26. The delay follows concerns raised by ChainSecurity over EIP-8037's proposed gas repricing mechanism. The firm said the change could cause smart contracts to permanently record failed operations and disrupt compatibility with existing mainnet contracts. During the 248th All Core Devs Execution meeting, core developers cancelled the planned fork, including a proposal to raise the gas limit to 200M. Hoodi does not yet have a new activation date. The testnet delay also pushes back the expected mainnet upgrade timeline, which had previously targeted early to mid-December. ETH market participants are watching for further Hoodi and EIP-8037 updates.

BTCUSD: Bitcoin Steadies Below $82,000 as ETF Flows Reverse Sharply. When Bottom?

Bitcoin steadied near $81,700 after falling more than 4.5% from Wednesday's peak above $84,800, as sharply reversing ETF demand added pressure ahead of Friday's options expiry. Spot Bitcoin ETFs recorded $635.6 million in net outflows Thursday, including $254.1 million from BlackRock's IBIT, while approximately $1.3 billion in Bitcoin options approached expiry with a reported max-pain level of $82,000. Bitcoin could face further downside toward $80,000 if buyers fail to defend support, while reclaiming $82,000 may signal an initial recovery.

Highlight Clip: Arthur Hayes: HYPE Could Significantly Underperform ETH and ZEC

Arthur Hayes warns that Hyperliquid's HYPE token could significantly underperform ETH and ZEC as competition intensifies and the perpetual DEX sector becomes a crowded consensus trade. Hayes acknowledged Hyperliquid's genuine market demand but said its investment risk-reward appeal has declined, and he previously disclosed selling all his HYPE and NEAR holdings. HYPE could face relative performance pressure if competition increases and investors favor alternative crypto assets, though Hayes's track record warrants caution when interpreting his forecasts.
