Robinhood launches its new Ethereum Layer 2 blockchain built on Arbitrum's technology stack, triggering a trading frenzy that processes over $568 million in daily volume. Under Arbitrum's Expansion Program, Robinhood Chain returns 10% of its net protocol revenue to the Arbitrum ecosystem. This surge in activity drives a 19% gain for Arbitrum's ARB token, while early transaction metrics far outpace initial revenue projections.
