Security auditing firm Dedaub is investigating gas-related risks in the proposed Ethereum Glamsterdam upgrade alongside ChainSecurity and internal audits

Vitalik Buterin defined Ethereum's core priorities using the acronym CROPS, standing for censorship and capture resistance, open source, privacy, and security

Vitalik Buterin identified post-quantum security, base-layer ossification, and strict limits on in-protocol rewards as technical requirements for Ether to function as a store of value

Vitalik Buterin stated on November 8, 2026, that the EIP-1559 fee-burning mechanism should remain active even if fee burns indefinitely cover less than 10% of new issuance breakeven levels

Network metrics reported on November 8, 2026, showed that EIP-1559 fee burns covered approximately 2.07% of new Ether issuance, leading to net supply growth

The planned October 26, 2026 activation of the Hoodi testnet with a 200 million gas-limit increase was postponed on October 22, 2026 pending resolution of security and gas accounting issues

On November 6, 2026, Ethereum Foundation developer Marius van der Wijden published an appeal asking application developers and auditors to evaluate eight gas invariants and report repair options for affected smart contracts

EIP-8037 raises gas costs for creating persistent state data, causing immutable smart contracts with fixed gas budgets or gas introspection checks to run out of gas and potentially lock user funds permanently

Proposed INV-8 rules for EIP-7702 delegation mean pre-execution gas failures can roll back nonce updates while keeping block inclusion, exposing valid authorizations to front-running and unauthorized contract ownership initialization

Ethereum core developers are evaluating proposed gas repricing changes in the upcoming Glamsterdam upgrade under EIP-8037 and EIP-8038 to control node state growth while supporting higher throughput

An open specification proposal, PR #12581, would prevent gas readings from increasing to address transaction subtraction issues under EIP-8037

Under the Glamsterdam upgrade proposal, creating a cold storage slot increases from 22,100 gas under Osaka to 110,020 total gas, comprising 12,100 execution gas and 97,920 state gas

On November 7, 2026, Ethereum community advocate Ryan Berckmans reversed his prior support for immediate activation of the Glamsterdam upgrade, stating the community failed on design and due diligence regarding gas opcode repricing

ChainSecurity's October 13, 2026 research indicates that changed state gas costs can cause a contract to record an underfunded operation as permanently unsuccessful, removing its retry path

A November 6, 2026 appeal from the Ethereum Foundation indicated that mainnet activation for the Glamsterdam upgrade remains unset

The Ethereum Foundation stated that the Hoodi testnet fork of the Glamsterdam upgrade will not proceed until smart contract gas issues are resolved

The Ethereum Foundation called for smart contract checks after security audits raised concerns regarding Glamsterdam upgrade proposals

An October 13, 2026 ChainSecurity report found EIP-8037 and EIP-8038 break smart contracts when external calls fail, tied to eight smart contract invariants

The implementation of the Glamsterdam upgrade on the Ethereum Hoodi testnet remains paused, with no confirmed mainnet activation date set as of November 6, 2026

The Ethereum Foundation outlined the Glamsterdam upgrade's layer-1 scaling features in a blog post published on September 28, 2026

Ethereum core developers delayed the implementation of the Glamsterdam upgrade on the Hoodi testnet until security concerns involving eight smart contract invariants are resolved
