[Robinhood as Landlord, Ethereum as Security Guard: An ARB L2 Brings Mainnet Settlement Fees Close to Zero] BlockBeats News, September 6: According to DefiLlama data, amid the Meme token speculation frenzy, Robinhood Chain recorded $2.61 million in protocol revenue yesterday and $22.45 million in protocol revenue over the past 7 days. As an Ethereum L2 based on Arbitrum Orbit, Robinhood Chain is required to allocate 10% of its net protocol revenue to the Arbitrum ecosystem. Over the past 7 days, Arbitrum, which provides the tech stack, received approximately $2.48 million (DAO + developer fund). As a DEX, Uniswap on Robinhood generated $609,234 in protocol revenue yesterday and $3.36 million over the past 7 days. Notably, Ethereum mainnet, serving as the settlement layer, earned minimal revenue. According to GrowThePie data, Robinhood Chain paid $1,270 in settlement fees to Ethereum mainnet yesterday and a total of $3,550 over the past 7 days. This phenomenon has sparked heated discussions within the community. Renowned DeFi researcher Ignas pointed out that this structure—where platforms make significant profits while the settlement layer earns almost nothing—raises the question of whether this is an issue for Ethereum. Ethereum might currently be using low "rent" to attract TradFi into its ecosystem, with plans to increase fees once user migration costs become sufficiently high. If the official roadmap indeed includes a strategy of "first attracting a large number of L2s, then monetizing L1 after switching costs rise," this could be bullish for ETH. However, such a strategy is not evident in Ethereum's current roadmap. Arbitrum co-founder Steven Goldfede commented that Robinhood chose Arbitrum to be a landlord, not a tenant. By controlling its own sequencer, Robinhood keeps the majority of the fees in its own pocket.
