Robinhood Chain recorded $2.61 million in protocol revenue on Sept. 5 and $22.45 million over the seven days through Sept. 5, according to DeFiLlama data, as speculation in meme tokens intensified. The Ethereum layer 2 (a secondary network for processing transactions) is built on Arbitrum Orbit and must allocate 10% of net protocol revenue to the Arbitrum ecosystem. Arbitrum received about $2.48 million over seven days for its DAO and developer fund. On Robinhood’s decentralized exchange, or DEX (a crypto trading platform without a central order custodian), Uniswap generated $609,234 in protocol revenue in one day and $3.36 million over seven days. Ethereum’s mainnet, which acts as the settlement layer, received only $1,270 from Robinhood Chain yesterday and $3,550 over the same seven-day period. DeFi researcher Ignas questioned whether a structure in which the application earns heavily while the settlement layer receives little represents a problem for Ethereum. Ignas said Ethereum may be using low fees to bring traditional finance into its ecosystem before raising its share once user migration costs become high, although he said that strategy is not visible in Ethereum’s current roadmap. Arbitrum co-founder Steven Goldfede said Robinhood selected Arbitrum to act as a landlord rather than a tenant, retaining control of its sequencer and collecting most of the fees.
