Arbitrum paused part of its own smart-contract platform, and it blamed AI-assisted attackers.

🧠 In plain words
Per CryptoSlate, Arbitrum's Security Council halted new activations of Stylus programs on Arbitrum One and Nova on October 2. Stylus lets developers write contracts in languages like Rust that compile to WebAssembly instead of Solidity. The council said attackers were using AI-assisted methods to hand-craft WebAssembly programs outside the standard toolchain. Think of a building that keeps its main doors open but locks a side entrance after someone tests the lock with a new tool. Solidity contracts are unaffected and existing Stylus programs run until they expire.

✅ What it means for you
• Arbitrum says the known bugs threaten chain liveness, meaning possible outages, and that it found no way to steal user funds.
• Stylus apps keep working, but updates needing fresh activation are blocked until the council reopens them. No date has been given.
• $ARB is down about 2.8% today and 11.3% on the week, per CoinGecko.

Takeaway: a precaution, not an exploit. The new detail is that AI tooling is now in the attacker's kit.
