Arbitrum has quietly completed a "power upgrade" just like that.

On January 8th, ArbOS Dia officially launched, and this is not a small patch. The new pricing model directly smooths out gas fee fluctuations, which users who trade frequently can feel the difference. At the same time, native mobile signature support was introduced—using biometric solutions like Passkeys and FaceID, taking the mobile wallet experience to a new level.

The significance of this upgrade is that while Arbitrum reduces costs, it also addresses the user experience ceiling at the Web3 application layer. Stable gas fees mean predictable transaction costs, and biometric support lowers the barrier to entry for crypto wallets. For the developer ecosystem and ordinary users, these are tangible improvements. The market hadn't fully reacted at the time, but such infrastructure-level optimizations often reveal their true power during subsequent application explosions.
