Uniswap Founder Responds to V4 Fee Switch Controversy, Clarifies Claim of "LP Fees Being Reduced" Is a Misunderstanding

Meta has launched two AI models, Muse Wonder and Muse Wonder Full, stating that they match or outperform top-tier products from OpenAI and Anthropic across multiple benchmark tests, and will be used to boost retention for its Muse assistant. Muse Wonder surpassed Anthropic’s Claude Opus 5.5, Fable 5.1, and OpenAI’s GPT-6 Astra in select technical benchmarks, and is capable of handling complex tasks including lease understanding, financial or health information analysis, and more. Meta Platforms CEO Mark Zuckerberg noted that the company has caught up to the "cutting edge" of artificial intelligence, will continue to invest heavily in AI development, and rejected calls to slow down AI progress. Following the news, Meta’s US stock closed up 3.38% at $742.96, according to market data from BIT (bit.com).

Yuga Labs’ Vice President of Blockchain Quit has issued a reminder that following Blur’s announcement of plans to shut down its website frontend, users should immediately revoke authorizations to Blur’s smart contracts. Quit stated that he has inspected Blur’s current contracts and found no exploitable vulnerabilities, but noted these contracts support upgrades, meaning malicious logic could still be introduced in future iterations. He pointed out that NFTs worth tens of millions of dollars remain authorized to Blur’s contracts, and the security of these assets effectively depends on the Blur team’s operational integrity. The executive added that the Blur team appears to be in the process of disbanding, so he recommends users revoke authorizations via tools such as revoke.cash to mitigate risks from potential contract vulnerabilities or future upgrades. Quit also referenced last month’s exploit of Magic Eden-related contracts, which resulted in millions of dollars in losses, noting he assisted in recovering a significant portion of those funds. That incident underscores the risks of retaining contract authorizations—especially as attackers gain access to more powerful vulnerability-detection tools. Yuga Labs CEO Figge also issued a reminder, emphasizing that Blur’s contracts are upgradeable, and users should revoke authorizations to avoid future security issues.

Beating AI Insight News Brief: Anthropic released a statement saying preliminary evidence shows new security measures have reduced the number of Claude inference tokens extracted by distillation attackers from its platform by approximately 90% to 99%. The company noted attackers typically use networks of fake accounts to bulk-collect model responses, unauthorizedly replicating its capabilities, adding that full inference records are more valuable for training than final answers. The new measures include restricting the transfer of inference records between conversations, models, and accounts, deploying a two-stage classifier to identify and block extraction requests, and rate-limiting or banning accounts that repeatedly attempt such attacks. Anthropic added the classifier has a false positive rate of less than 0.1%, and it has banned tens of thousands of distillation-related accounts, often completing bans within two hours of the start of relevant attacks. Additionally, since September 24, the company has resumed charging for requests blocked by security protections in specific categories such as distillation. Anthropic acknowledged that some developers will need to update their integration methods, and the classifier may also incorrectly block legitimate requests. It remains unclear how long the protective effects will last, and the company has not yet encountered highly sophisticated, sustained circumvention attempts, so it will continue to iterate on its defense measures.

According to HTX market data, BLUR has fallen more than 27% in the past 24 hours, currently trading at $0.0139, due to news that Blur is discontinuing its website frontend. Earlier reports noted that Blur announced its blur.io website frontend will be shut down on November 12, 2026.

Meanwhile, Blend will stop matching new loans on the same day.
