Arbitrum deployed its ArbOS 61 'Elara' upgrade on August 20, introducing optional compliance screening tools that Orbit chain owners can control on their dedicated networks.

Ring Protocol has integrated Orbs-powered infrastructure to support decentralized limit and TWAP orders across Ethereum, Base, Arbitrum, and BNB Chain, bringing advanced trading features typically found on centralized exchanges to decentralized platforms.
Robinhood Markets launched Robinhood Chain, an Ethereum layer-2 blockchain built on Arbitrum technology for tokenized stocks and real-world assets.

Arbitrum announced that all Layer 2 chains built with its technology that settle outside of Arbitrum One or Nova will pay 10% of net protocol revenue to the Arbitrum ecosystem.
