Arbitrum pauses new Stylus activations due to AI-assisted attack risks
On October 2, 2026, Arbitrum's Security Council temporarily halted new Stylus contract activations on Arbitrum One and Nova as a precaution against increasingly sophisticated AI-assisted attacks targeting WebAssembly programs. Existing Stylus applications remain operational, and the restriction does not affect other contract deployments. The Council implemented this measure by raising the activation gas requirement to a prohibitively high level.
Key points
- Arbitrum's Security Council pauses new Stylus activations to mitigate AI-assisted attack risks.
- Existing Stylus applications continue to function without disruption.
- The activation gas requirement was increased to prevent new Stylus contract activations.
