• 10% of Robinhood Chain’s net protocol revenue flows back to the Arbitrum ecosystem

---

Arbitrum’s ARB token jumped 19% in 24 hours on July 9, making it the top performer among the top 100 cryptocurrencies. The move was driven by strong early activity on Robinhood Chain, which launched publicly just one week ago.

Robinhood Chain is built on Arbitrum’s Layer-2 infrastructure. On Wednesday alone, the new chain processed $568 million in daily trading volume, according to blockchain data from Entropy Advisors. It had already logged over $350 million by Thursday.

Much of that activity came from memecoin trading. Stablecoin balances on the network also climbed quickly, crossing $260 million in the first week.

The activity is generating real revenue for the Arbitrum ecosystem. Under the agreement, 10% of Robinhood Chain’s net protocol revenue goes back to Arbitrum, split between the DAO treasury and the Developer Guild.

Brendan Ma, head of investment strategies at the Arbitrum Foundation, posted on X that based on Wednesday’s activity alone, Robinhood is “run-rating at more than $12.5 million in annualized revenue already.” He also noted that most tokenized real-world asset activity has yet to arrive on the chain.

Crypto analyst Michaël van de Poppe weighed in on X, saying he was “very pleased to see the strength in $ARB currently.” He pointed to momentum from both Robinhood Chain activity and broader Ethereum network strength, and identified a “massive bullish divergence” on ARB’s USD and BTC pairs. He said he expected “a lot more momentum coming into the price action” in the coming weeks.

I’m very pleased to see the strength in $ARB currently.

It’s taking some momentum due to the strength on the Robinhood chain and the activity on Ethereum in general.

There’s a massive bullish divergence on the USD and $BTC pairs on this one, so I would expect to see a lot more… https://t.co/fyym17tqn0 pic.twitter.com/xKetwE0XNK

Early Numbers Beat Forecasts

An April report from FalconX had projected Robinhood Chain would generate around $1.1 million in transaction fees in its first six months. The chain has already blown past that pace in its opening days.

FalconX also projected that revenue could grow to $60 million annually by 2030 as users expand beyond tokenized stocks into DeFi and other onchain applications.

Robinhood unveiled the chain at a London event last week. Alongside the launch, the brokerage announced plans to expand tokenized U.S. stock access to customers in over 120 countries and launched a DeFi savings vault using the Morpho lending protocol.

Price Levels to Watch

ARB is trading back toward a descending trendline that has capped recovery attempts since the start of the year. A close above that level could open a move toward the $0.10–$0.11 resistance zone, then the $0.14 area.

If the rally stalls, the $0.08 support level is where traders are watching for signs of renewed accumulation.

Brendan Ma noted that most tokenized real-world asset activity tied to Robinhood Chain has not yet arrived on the network.
