Arbitrum’s ARB token rose 19% over 24 hours, leading gains among the top 100 cryptocurrencies, as Robinhood’s new blockchain saw a sharp burst of onchain trading activity. Robinhood Chain processed more than $568 million in daily trading volume on Wednesday, according to blockchain data cited by CoinDesk.
The move matters because Robinhood Chain is built on Arbitrum’s technology stack, linking the brokerage’s early onchain activity to the broader Arbitrum ecosystem. Under the agreement, 10% of Robinhood Chain’s net protocol revenue is directed back to Arbitrum, split between the DAO treasury and the Developer Guild.
CoinDesk reported that much of the early trading was driven by memecoin activity, while stablecoin balances on the network rose above $260 million within its first week. The chain also logged more than $350 million in volume so far on Thursday, extending its strong start after becoming available to a broader public audience a week earlier.
Robinhood introduced the chain at a London event as part of a larger crypto expansion. The brokerage also announced plans to broaden access to tokenized U.S. stocks for customers in more than 120 countries, launch a DeFi-powered savings vault using Morpho, and expand into areas including AI-powered trading and additional asset classes.
FalconX had previously projected Robinhood Chain could generate about $1.1 million in transaction fees during its first six months. CoinDesk also cited FalconX’s forecast that transaction-related revenue could reach $60 million annually by 2030 if users move beyond tokenized stocks into DeFi and other onchain applications.
