Robinhood Chain's $568M day hands Arbitrum a 19% glow-up — now do it again tomorrow

Arbitrum's ARB token climbed 19% over 24 hours to lead gainers in the top 100 cryptocurrencies after Robinhood Chain, built on Arbitrum's technology stack, logged $568 million in daily trading volume on Wednesday and more than $350 million through Thursday, according to blockchain data from Entropy Advisors. Bitcoin ($BTC) edged 1.5% higher above $63,000, trading at $64,038.99, while ether ($ETH) rose 0.5% in an otherwise muted session. ARB touched a two-week high of $0.085 before retracing to around $0.083, with daily volume up 118% to $105 million.

Much of the activity on Robinhood Chain, which opened to the broader public one week ago at Robinhood's London event, was driven by memecoin trading, while stablecoin balances on the network climbed above $260 million within its first week. Under the arrangement, 10% of Robinhood Chain's net protocol revenue flows back to the Arbitrum ecosystem, split between the tokenholder-controlled DAO treasury and a developer allocation. Arbitrum developer Steven Goldfeder specified that 8% of fees collected on Robinhood Chain and other Arbitrum L2s are directed to the tokenholder-controlled treasury and 2% to development, while 100% of fees collected on Arbitrum One go to the Arbitrum treasury. Robinhood's DEX trading volume hit a record $560 million on July 8, with DefiLlama showing App Fees of $2.36 million that day and $2.12 million on July 9.

Brendan Ma, head of investment strategies at the Arbitrum Foundation, wrote on X that "Based on just yesterday's activity, Robinhood is run-rating at more than $12.5 million in annualized revenue already," adding that most activity tied to tokenized real-world assets has yet to arrive. An April FalconX report had projected the chain could generate about $1.1 million in transaction fees in its first six months and roughly $60 million in revenue for Robinhood. Robinhood separately announced it would expand tokenized U.S. stock access to customers in more than 120 countries, launched a DeFi-powered savings vault offering yields through lending protocol Morpho, and outlined plans to extend its crypto business into AI-powered trading and additional asset classes.

Despite the price recovery, ARB's Relative Strength Index climbed to 54, edging into bullish territory, and supply-side pressure remains. In July, 92.63 million ARB worth approximately $7.6 million will enter circulation through scheduled unlocks, underscoring the inflationary backdrop
