ARB Rises Nearly 20% as Robinhood Chain Brings Arbitrum’s Revenue-Sharing Model Back Into Focus
ARB was one of the strongest-performing major Layer 2 tokens over the past week, with the token briefly reaching $0.094 intraday and gaining nearly 20% over seven days. The move followed the launch of Robinhood Chain, a real-world asset-focused Layer 2 built with Arbitrum technology that went live on July 1 at a launch event in London. What caught the market’s attention was not just the chain itself, but the revenue-sharing framework behind it. Under Arbitrum’s Expansion Program, or AEP, certain Orbit chains that settle outside Arbitrum One or Nova must send 10% of net protocol revenue back to the Arbitrum ecosystem, with 8% going to the ArbitrumDAO treasury and 2% to the developer guild. The mechanism has existed since January 2024, but Robinhood Chain is the first large-scale project to give that structure visible commercial weight. Still, the current revenue base remains small. Citing Dune data, the source article said Robinhood Chain had generated about $147,000 in protocol revenue as of publication, or roughly $146,000 after Ethereum L1 settlement costs. That means the immediate portion flowing back to Arbitrum is limited, and the recent ARB rally appears tied more to a repricing of AEP’s future potential than to any meaningful near-term cash flow.
