Arbitrum has recently rolled out exciting updates to its fee system with the introduction of dynamic pricing, making transactions fairer, more predictable, and better suited for real-world use. This change builds directly on the ArbOS Dia upgrade that went live in early January 2026.
Previously, gas fees on Arbitrum could spike sharply during busy periods, much like surge pricing in ridesharing apps. The old system relied on a single gas target and adjustment window, which sometimes led to unpredictable costs when demand surged.
With the Dia upgrade, Arbitrum shifted to a smarter approach: multiple higher gas targets tracked over several longer adjustment windows. Instead of one simple number, the final fee comes from combining these factors. This smooths out spikes, shortens how long high fees last, and keeps things stable even under heavy traffic. They also raised the minimum L2 base fee slightly from 0.01 gwei to 0.02 gwei to discourage spam and help balance network revenue.
Even more importantly, Dia lays the groundwork for full dynamic pricing. It now tracks real resource usage—like compute power, storage access, storage growth, and history growth—separately, rather than lumping everything into one “gas” unit. This means users pay only for what they actually use, creating a more efficient system that reflects true network bottlenecks.
The result? Builders get a reliable platform for apps, enterprises enjoy consistent costs during peak times, and everyday users face fewer surprises. It’s a big step toward sustainable scaling—potentially unlocking much higher throughput in the future without wild fee swings.
As shared from the official Arbitrum channel, this is about building an onchain platform where fees support growth, not get in the way. You only pay for what you use, and that’s how strong capital markets—and great user experiences—thrive on Arbitrum
