Arbitrum to receive 10% of fees from Robinhood Chain and other Layer 2s built with its technology

Jul 9, 2026

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.

▪Every Layer 2 chain built with Arbitrum's technology that settles outside of Arbitrum One or Nova must return 10% of its net protocol revenue to the Arbitrum ecosystem.
