Arbitrum’s ARB Extends Weekly Slide After Security Council Takes Emergency Action

Arbitrum’s license fees brought in about $4.75 million or 87% of the total revenue, while transaction fees contributed $507,000, and treasury income amounted to $181,000.

• ARB has fallen 12% in the past week despite rising 47% in the past month.
• The Arbitrum Security Council halted new Stylus contract activations on Arbitrum One and Nova due to increasingly sophisticated attacks.
• The Foundation said no vulnerability that could steal user funds has been found, so existing Stylus contracts remain live.

Arbitrum (ARB) extended its one-week drop after emergency action by the network’s Security Council. The token traded in the red on Sunday, down about 12% in seven days.

In a report on the action, the Arbitrum Foundation said the Council paused new Stylus contract activations on Arbitrum One and Nova on Thursday. It moved at 11:30 a.m. ET. Live contracts continue to run. None of them mature before Aug. 20, 2027, the Foundation said.

The pause applies to new contracts and apps that require a new activation to update. The Foundation said it is going after hand-built WebAssembly programs that circumvent the normal Stylus toolchain. It said such AI-assisted tools have made attacks on those programs more sophisticated.
