Robinhood Chain has generated approximately 17,171 ETH, worth $42.58 million, in cumulative onchain revenue during its first 70 days of mainnet operation, according to onchain data reported on September 8.
That works out to an average of approximately $608,000 per day since the network launched on July 1. The revenue is divided between Robinhood Chain and Arbitrum, whose technology underpins the layer-2 network. Approximately 90%, or 15,454 ETH worth $38.32 million, has accrued to Robinhood Chain, while the remaining 10%, equivalent to about 1,716 ETH or $4.26 million, has gone to the Arbitrum ecosystem. The figures highlight how quickly Robinhood Chain has developed an economic footprint following its mainnet launch.
Trading Boom Pushes Chain Revenue Higher
Revenue has accelerated particularly sharply during the network’s second month. Users paid a record approximately $3.75 million in fees on September 1, according to The Block, placing Robinhood Chain ahead of Ethereum and Base on that day’s chain-fee rankings. Separate data showed protocol revenue reaching approximately $2.61 million on September 5 and $22.45 million over the preceding seven days. Trading activity has been the primary driver.
Decentralized exchange volume surpassed $1.5 billion on September 1 and subsequently accelerated above $3 billion per day, with Uniswap capturing the overwhelming majority of trading during peak sessions. Robinhood Chain is also processing millions of transactions daily. Growthepie data cited on September 7 showed approximately 7.5 million transactions and 345,700 active addresses during the latest complete day. However, current activity comes with an important qualification. Robinhood is subsidizing gas fees for eligible Robinhood Wallet transactions during the network’s first 90 days, reducing transaction costs for users and potentially boosting both transaction and address counts.
Arbitrum Captures 10% of Revenue
Robinhood Chain was built using Arbitrum technology, creating a direct economic relationship between the rapidly growing network and the broader Arbitrum ecosystem. Under Arbitrum’s Expansion Program, chains settling outside Arbitrum One and Nova return 10% of net protocol revenue to the Arbitrum ecosystem. That arrangement was already becoming material before Robinhood Chain’s latest surge. Arbitrum DAO reported $6.19 million in total income during the first half of 2026. In July, its first month receiving Robinhood Chain-related payments, Expansion Program licensing fees generated approximately $360,000 and represented 35% of DAO income for the month.
The latest cumulative figures suggest that contribution has increased substantially as Robinhood Chain activity accelerated. There is nevertheless an important distinction between blockchain revenue and Robinhood Markets’ corporate revenue. The reported $42.58 million represents revenue generated at the chain level. It should not automatically be interpreted as $42.58 million appearing on Robinhood’s income statement, particularly because revenue definitions differ between analytics platforms and some activity involves third-party applications. Robinhood Chain’s economics are also unusual relative to Ethereum itself. Recent data showed the network generating millions of dollars in daily revenue while paying only thousands of dollars in settlement costs to Ethereum mainnet.
That structure allows the layer-2 operator to retain much of the economic value created by transaction sequencing while still ultimately settling to Ethereum. The next major test comes when Robinhood’s introductory gas subsidy ends. If transaction volumes and fee generation remain elevated once users bear more of the network’s costs directly, the first 70 days could represent the beginning of a durable revenue stream rather than launch-driven activity. For now, 17,171 ETH in cumulative revenue demonstrates that Robinhood Chain has moved from a new brokerage-backed blockchain to a meaningful fee-generating network in little more than two months.
