Arbitrum Surges on Robinhood Chain Activity but Unlock Risk Looms

ARB rallied roughly 30% as Robinhood Chain activity showed rising fees, revenue, volume, TVL, stablecoins, and open interest, offering a more measurable catalyst than a purely promotional narrative. Arbitrum Expansion Program value capture remains unproven, while resistance near $0.15 and a scheduled September 16 unlock create confirmation and supply-pressure risks.
