Arbitrum, Solana founders spar over Robinhood Chain fee model

The dispute highlights a fundamental tension in L2 economics: whether chains should prioritize low user fees or capture more revenue for the base layer. Goldfeder's framing of Robinhood as a 'landlord' versus Toly's cost comparison suggests the real issue is who profits from user activity, not just the headline fee split. This matters for other appchains or enterprises considering their own L2s, as the model's sustainability depends on whether revenue-sharing arrangements align incentives across layers. The open question is whether such fee structures will attract or deter future partners, and whether Arbitrum's approach becomes a template or a cautionary tale.
