Ethereum Rises 8% in a Month, but Arbitrum Soars 135%. Is Robinhood Chain to Blame?

Arbitrum (ARB) surged 135% in a month, outperforming Ethereum's (ETH) 8% gain. The rise is linked to Robinhood Chain, built on Arbitrum, which generated $1.9M in revenue on September 1. ARB holders benefit indirectly through a 10% revenue share to the Arbitrum DAO. As of September 24, ARB is trading around $0.21, while ETH is at $2,694. The SEC's exemption for tokenized U.S. stocks may have also contributed to the rally in Ethereum's layer-two networks.
