Arbitrum quietly completed a "power upgrade" like this.

On January 8th, ArbOS Dia officially launched, and this is no small patch. The new pricing model directly smoothed out gas fee volatility issues, which users who trade frequently can feel the difference in. At the same time, it introduced native mobile signature support—through biometric solutions like Passkeys and FaceID, the user experience of mobile wallets reached a new level.

The significance of this upgrade lies in the fact that while Arbitrum is reducing costs, it's also solving the user experience ceiling of the Web3 application layer. Stable gas fees mean transaction costs are predictable, and biometric support pulls down the barrier to entry for crypto wallets. For both the developer ecosystem and ordinary users, these are tangible improvements. The market hadn't fully reacted at the time, but this type of infrastructure-level optimization often shows its power when applications subsequently explode.
