The ArbOS Dia Upgrade is Now Live on Arbitrum

On Thursday, the Arbitrum team announced via X that the ArbOS Dia upgrade is now live on Arbitrum. The Dia upgrade brings Arbitrum into the next generation of Ethereum-aligned execution changes while advancing four product narratives that matter to companies shipping at scale:

  • Smoother gas prices on Arbitrum One & Nova

  • A foundation for more throughput with similar hardware

  • Mobile & enterprise-grade authentication tools

  • Continued alignment with Ethereum’s Fusaka-era EVM

Dia includes pricing updates for Arbitrum One to reduce the severity, frequency, and duration of high L2 gas prices during elevated demand.

Arbitrum is a suite of scaling solutions on Ethereum that utilize Optimistic Rollup. It allows users to enjoy faster speed and cheaper transaction costs when interacting with web3 dApps. ARB, the native coin of the Arbitrum network, is down 0.76% today and is trading at $0.2086.
