Robinhood Chain collected $4.5 million in transaction fees on September 3 while paying Ethereum roughly $398 to post the day's data and proofs, according to a Bitquery investigation. The gap shows how little Layer 1 settlement can cost even during heavy activity on an Ethereum Layer 2, though a separate analysis argues that L2 transaction growth and Ethereum's direct fee capture can diverge sharply.
A $4.5 million day cost $398 to settle
Bitquery found that Robinhood Chain charged users $4,503,705 on September 3 while roughly $396 went toward posting data to Ethereum and another $2 covered proving costs. That produced a fee-to-settlement-cost ratio of about 11,400 to one.
Bitquery examined the chain from its first block on April 30 through September 3 and counted roughly 597 million transactions across 54 million blocks, generating about $23 million in cumulative fees. Around 70% of those fees arrived from August 24 onward, once the network's base fee moved off its 0.02 gwei floor. Daily fees jumped from $54,701 on August 22 to $4.50 million on September 3 as gas consumption roughly tripled.
Bitquery cautioned that the difference is not Robinhood's profit, since its calculation excludes staff, hardware, and other operating costs. Nor does the $398 represent revenue to an entity called Ethereum — it measures only Robinhood Chain's cost of using Ethereum for settlement.
Cheap blobs, but real trade-offs
Robinhood Chain runs as an Arbitrum Layer 2 on Ethereum, using ETH as its native gas asset and posting transaction data through Ethereum blobs, a mechanism Ethereum built specifically to lower settlement costs. South Korea's Digital Asset separately cited roughly $49,000 in cumulative on-chain costs paid to Ethereum since late April, averaging close to $370 per day.
L2Beat says only two whitelisted validators can currently challenge Robinhood Chain's state updates, and the chain runs a centralized sequencer that can extract MEV from transaction ordering. The network was securing roughly $2.99 billion in value at L2Beat's latest check, with about 114 user operations per second.
Arbitrum takes a cut too
Under its Arbitrum Expansion Program license, Robinhood Chain must return 10% of net protocol revenue to the Arbitrum ecosystem. The Arbitrum Foundation said Expansion Program licensing fees reached $360,000 in July, accounting for 35% of ArbitrumDAO income that month.
Bitquery also found that eight contract addresses drove 79% of the September 3 gas-demand increase, including one swap router that alone handled 1.7 million transactions and paid about $1.1 million in fees. By September 10, Robinhood Chain's gas revenue had fallen to roughly $944,000, showing the September 3 spike was not a stable daily rate.
