Robinhood developed its own chain based on Arbitrum and has been operating it successfully, giving new life to L2 solutions that even Vitalik had declared dead and abandoned. The $ARB token surged 50% overnight because, according to the documentation, Robinhood is required to return 10% of its protocol revenue to Arbitrum. Since Robinhood launched on July 8th, its average daily revenue has been around $100K, meaning Arbitrum could earn $10K daily. However, yesterday, Robinhood's revenue skyrocketed to $1.92M, which means Arbitrum could earn $190K. Although, to be honest, even if all this money were used to buy back $ARB tokens, it would still be a drop in the ocean. But on one hand, Robinhood's revenue expectations are still growing, and on the other hand—and more importantly—in the crypto world, how much money you make is less important than whether you have the ability to make money. Either way, a price pump is always a good thing. That said, the one feeling the most pain from this wave is $OP. After all, it’s the OG of one-click chain deployment. First, it lost a major client, Base, and now it couldn’t secure Robinhood. But looking at Base’s experience, it’s understandable. Being based on $OP meant development and upgrades were constrained by OP’s own progress. Most importantly, Base had to continuously share profits with OP. For context, Base only gave OP a mere 2.5% profit share, and in return, OP subsidized Base with 120M tokens. Meanwhile, Robinhood is giving Arbitrum a full 10% without receiving any subsidies. In comparison, Robinhood does seem like it got the short end of the stick. Especially since Robinhood is a publicly listed company, it will inevitably face shareholder scrutiny in the future. So, we can pretty much guess how this ‘marriage’ will end.
