Blur announced it will shut down its frontend on November 12, leaving only the protocol to operate on-chain. Yuga Labs executives immediately warned that millions of dollars worth of NFTs still have authorized access to Blur’s contract, and future upgrades could introduce malicious logic.

Number one digital trading platform Blur has officially announced that its frontend marketplace will be shut down on November 12, 2026, while its protocol will continue operating on the Ethereum chain. Shortly after, senior executives from Yuga Labs, the parent company of Bored Ape Yacht Club (BAYC), urgently posted on X, advising all NFT holders to immediately revoke their authorization to Blur’s contracts to avoid potential malicious logic being introduced in future contract upgrades.
Blur frontend disabled, protocol still active
Blur has posted an official announcement on X, stating that this suspension only affects the Blur frontend website, while the underlying market protocol continues to operate on-chain, and the BLUR token retains its fee switch governance rights. Meanwhile, Blend, Blur’s NFT lending protocol, also ceased matching new loans on the same day. Borrowers must repay their loans by November 12 or choose to default. Blur has stated that after the suspension, it will provide frontend tools to help users withdraw assets from Blend.
After the announcement, the price of BLUR dropped. According to OKX market data, BLUR is currently trading at $0.0194, down 7.75% over the past 24 hours.

This deprecation only applies to the frontend.
The Blur marketplace protocol will remain operational on-chain, and $BLUR will continue to control its fee switch.

Yuga Labs: Multi-million-dollar NFTs remain exposed to licensing risks
Approximately two hours after Blur’s announcement, Yuga Labs’ Blockchain Vice President Quit posted on X, warning users to immediately revoke permissions via revoke.cash or similar tools. Quit noted that he had reviewed Blur’s current contracts and found no exploitable vulnerabilities, but these contracts are upgradeable, meaning malicious logic could still be introduced in the future.
According to estimates, there are still NFTs with a total value in the millions of dollars that have granted open authorization to the Blur contract, and the actual security of these assets relies entirely on Blur team’s operational safety. He noted that the team appears to be dissolving, and the risk cannot be ignored.
Yuga Labs CEO Figge also expressed the same view, reiterating that Blur contracts are upgradeable and reminding users to revoke approvals to avoid future security issues.
Because this is happening, it’s really important to revoke your approvals on Blur
Blur has upgradable contracts

Magic Eden’s Lesson: Never Leave Contract Approvals Active
The warning about Quit is not unfounded. Last month, a vulnerability exploited in a Magic Eden-related contract resulted in the loss of millions of dollars; Quit personally helped recover a significant portion of those funds. This incident clearly demonstrates that, in an era where attackers possess increasingly powerful vulnerability-exploitation tools, maintaining contract approvals is equivalent to entrusting the security of your assets to the goodwill of the development team.
How should users operate?
Users who hold NFTs that have interacted with Blur can revoke authorization through the following steps:
① Visit revoke.cash (must be connected to the same wallet)
② Search for Blur-related contract addresses
③ Revoke approval one by one
If you haven't traded NFTs on Blur before, no special action is typically required. However, due to the less transparent authorization mechanisms in NFT marketplaces, all holders of high-value NFTs are advised to review their wallet authorization status once.
Blur also reminds users to be cautious of fake accounts and false announcements impersonating Blur.
