Arbitrum just rolled out its 'Dia' upgrade—a solid step forward for the network. The update tackles two major pain points: it stabilizes gas fees so users won't get hit with crazy spikes, and brings mobile authentication to the table through Passkeys and FaceID support. This kind of infrastructure improvement matters because it directly impacts user experience, especially for those accessing the network on mobile devices. The combination of predictable gas costs and smoother mobile onboarding could make a real difference in adoption.
