Arbitrum Pauses New Stylus Activations in Emergency Security Action
Arbitrum paused new Stylus activations and kept existing Stylus contracts running and renewing. The action also added a BoLD guard that can delay unconfirmed withdrawals if it accepts contradictory proofs. The temporary measure covers Arbitrum One and Nova, while Solidity deployments remain operational.
What this rests on
What it means
Each sentence links inside to the piece that supports it.
For users and developers on Arbitrum One and Nova, the immediate change is that new Stylus activations are paused while existing Stylus contracts continue to operate. Solidity deployments are still operational, so the pause does not touch that part of the network activity.
In practice, the network has added a BoLD guard that can delay withdrawals that have not been confirmed if it accepts contradictory proofs. That means the withdrawal path now has an extra condition that was not described before, while already active Stylus contracts can still run and renew.
