- ARB is the strongest performer among the 100 largest cryptocurrencies over the past 24 hours.
- Robinhood Chain runs as a dedicated Arbitrum chain and sends 10% of net protocol revenue back to the ecosystem.
- Ethereum’s payment from the same chain fell while gross revenue multiplied.
- Futures open interest rose with the price, pointing to fresh long positions.
Arbitrum’s ARB token climbed roughly 27% over 24 hours to trade near $0.1092 on Tuesday, the biggest gain in the top 100 by market value, after Offchain Labs co-founder Steven Goldfeder disclosed that Robinhood Chain’s 24-hour transaction revenue had moved past $2 million. Robinhood Chain is built as a dedicated Arbitrum chain, and under the Arbitrum Expansion Program it routes 10% of its net protocol revenue back into the Arbitrum ecosystem. The token has spent most of 2026 within a short distance of $0.0704, the floor of its current range, so a third-party chain producing measurable, recurring fees gave the market something it has not had a way to price all year.
JUST IN: Robinhood Chain generated more than $1M in fees over the last 24 hours

The Arbitrum account posted the $1 million milestone on Sunday. Goldfeder’s figure, published a day later, showed the chain had roughly doubled that in the following 24 hours.
Nine days took gross revenue from $54,676 to over $1 million
The revenue curve explains the move better than the price chart does. ARK Invest analyst Lorenzo Valente calculated that gross chain revenue on Robinhood Chain rose from $54,676 on 22 August to $1,087,896 on 30 August, close to a twentyfold increase in nine days. Arbitrum’s share went from about $5,400 to roughly $108,000 across the same window. Goldfeder’s Monday figure of more than $2 million in a single day was itself up from around $1.22 million twenty four hours earlier.
At that run rate, Arbitrum’s cut annualises near $73 million. Back in early July, the Arbitrum Foundation’s Brendan Ma extrapolated from the chain’s first full trading day and arrived at just over $12.5 million annualised. The distance between those two numbers is what traders spent Monday and Tuesday repricing.
Arbitrum’s share is shown as 10% of gross for comparability. The Expansion Program fee applies to net protocol revenue, so the actual figures sit below these. Sources: ARK Investment Management, based on Blockworks onchain data, for 22 and 30 August; Steven Goldfeder for the latest 24-hour figure.
Ethereum was paid less on 30 August than on 22 August
The most revealing number in the ARK data is not the growth rate. Ethereum’s settlement cost from the same chain fell from $247.79 on 22 August to $155.30 on 30 August, while gross revenue multiplied twenty times. Valente put the correlation between Ethereum’s cut and Robinhood Chain’s gross revenue over 16 to 30 August at minus 0.22.
The structures behind the two payments are not comparable. Ethereum charges a settlement cost, not a revenue share. A rollup posts compressed transaction data and validity proofs to Ethereum at a price set by Ethereum’s blob market, and that data footprint stays roughly the same whether the chain above it earned $50,000 or $1 million that day. Expressed as a share of gross revenue, Ethereum’s take dropped from 45.3 basis points to 1.4.
Arbitrum’s license does the opposite. The Expansion Program fee is a percentage of revenue, so the payment tracks activity directly. That single design difference is why a Robinhood Chain revenue print moves ARB and leaves ETH untouched.
The 10% splits into 8 and 2 before a holder sees anything
The fee share is not one pool. Goldfeder has described the structure as 8% going to the treasury controlled by tokenholders through the Arbitrum DAO, with 2% funding development through the Developer Guild. Any chain built on the Arbitrum Orbit stack that settles outside Arbitrum One owes this share by default.
Two conditions sit alongside those figures. Holders receive no direct distribution, since the money accrues to a treasury whose spending runs through governance votes. Robinhood has also been covering network fees for the chain’s first 90 days, a subsidy that started on 8 July and runs to roughly late September, which means every usage figure published so far describes a market where transacting is free.
$0.1202 lasted minutes, $0.0980 lasted the close
The daily candle is more informative than the percentage headline. ARB opened at $0.1094, spiked to $0.1202 and settled back near $0.1086, leaving a long upper wick. A wick that size means buyers drove the price up and met heavy selling near the top, so the highest prices of the session found no support.
Where it stalled is the useful part. The $0.1200 area sits just above the 0.618 retracement of the fall from $0.1496 to $0.0704, which lands at $0.1134, and the price closed back underneath it. Volume reached 373.71 million ARB, the heaviest session on the visible chart, so this was a rejection on real participation rather than a thin order book.
The 200-day average at $0.0980 carries the most weight. ARB traded beneath it through the summer, and a daily close above it marks the first time since May that the token has been priced above its longer-term trend. Holding that level through the week is the practical test of whether this repriced or simply spiked.
Open interest rose 10% while altcoin season hit a 90-day low
Derivatives data argues against reading this as a squeeze. Open interest in ARB futures rose more than 10% in step with the price, a combination that indicates traders opening fresh long positions rather than shorts being forced out of existing ones. Annualised funding sat near 8%, elevated but well short of the levels that mark a crowded, expensive trade.
The wider market was not helping either. The Altcoin Season index fell to 26 out of 100, its lowest reading in more than 90 days, and Bitcoin drifted around $78,000, down slightly on the day and on the week. ARB moved on its own.
Three dates now carry the story
The 90-day fee subsidy expires in late September, and that is the first real measurement of how much volume survives once users pay for their own transactions. The Arbitrum DAO then has to decide what to do with a treasury inflow running near $200,000 a day, and those governance proposals determine whether the fee share becomes value for holders or stays a balance sheet entry. Tokenized real-world asset activity, the segment FalconX built its $60 million by 2030 revenue projection around, has still not started in earnest.
Security researchers flagged wallet drainers, honeypot contracts and impersonation schemes on Robinhood Chain within days of the July launch, and that exposure grows with volume rather than shrinking. A chain clearing over $2 million in daily fees is a far more attractive target than one clearing $50,000, and Robinhood’s handling of that will shape whether institutional flow ever follows the memecoin flow onto the network.
