The Ethereum Foundation published a blog, reminding contract developers and auditors to check whether their projects rely on 8 Gas billing assumptions, which will no longer hold due to the adjustments in Gas charging methods in Glamsterdam with EIP-8037 and EIP-8038. The Ethereum Foundation has established a code repository that provides explanations, examples, and keywords for self-checking related to each assumption. Affected projects can contact the team via email.The team is collaborating with several auditing companies and conducting internal audits, but it cannot cover all projects on Ethereum and their on-chain and off-chain code. The Ethereum Foundation announced on October 23 that it has postponed the Glamsterdam upgrade originally scheduled to be activated on the Hoodi testnet, with a new activation time yet to be determined. Ethereum Foundation researcher Toni Wahrstätter stated on October 26 that the reason for the delay was a report from ChainSecurity that revealed issues with EIP-8037 when interacting with certain contracts, and its impact is now largely understood.

According to a report by CryptoSlate, on-chain data company Bitquery analyzed 3,170 wallets that reported profits of at least $100,000 on the token issuance platform Pumpfun from October 2025 to August 2026, involving a total profit of approximately $752.5 million. Among them, only 26% were checked through regular market transactions, 51% involved the sale of tokens transferred from other addresses, 13% exhibited potential collaborative trading patterns, and another 10% could not be clearly classified.The report stated that the tokens transferred in do not generate buy transactions that can be replicated by trading systems, so the profits displayed by the wallets may not be realizable by copy traders. The study has not measured the actual earnings of copy traders, and the token transfers themselves are insufficient to prove the existence of manipulation.

Revoke.cash issued a reminder that due to last week's Magic Eden security incident, Revoke.cash advises users to go to the Auto-Revoking module on their account page to check if there are yellow warning icons on each network; if so, they need to first restore that address to a regular account in other wallet applications, and then upgrade it to a smart account through MetaMask.In addition, users should confirm that all active networks are enabled and ensure that each wallet in the subscription is granted the relevant permissions individually. Revoke.cash added that Ultimate subscription users need to confirm that their wallets meet two conditions for the Auto-Revoking feature to properly protect assets: first, the Auto-Revoking permission must be granted for that wallet in MetaMask; second, the wallet must be upgraded to a MetaMask smart account on the corresponding network. Typically, the second step is automatically completed during the authorization process, but if the address has previously been upgraded to a smart account through other wallet applications, the upgrade may fail.

According to Bloomberg, the UK digital bank Revolut launched the UK's first facial recognition checkout system "Pay with Smile" on September 23, allowing customers to complete payments in-store through facial recognition.This feature operates on the Revolut Register terminal, where users can complete facial identity verification by clicking "Pay with Smile" on the screen during checkout, a process similar to unlocking a smartphone or accessing a banking app. Facial data is end-to-end encrypted, merchants do not store personal data, and users must actively choose to opt-in in the Revolut app settings, with the ability to withdraw consent at any time. Revolut charges a 0% processing fee for Pay with Smile transactions to alleviate the burden on independent merchants.The pilot will take place from September 24 to 26 at three Kiss the Hippo cafes in Bloomsbury, Chelsea, and Soho in London, with plans to roll out the feature to all 12 locations later this year. Sales promotion for the Revolut Register terminal will be launched at the appropriate time.
