Robinhood Chain Posts Record $3.75 Million Daily Fees as Arbitrum DAO Reports $6.19 Million First-Half Income

Robinhood Chain recorded $3.75 million in transaction fees on September 1, marking its highest single-day total since launching on mainnet July 1 and placing it ahead of Ethereum mainnet and Base for the day. The activity also generated more than $1.5 billion in decentralized exchange volume and lifted total value locked above $750 million.

The two-month-old network, built on Arbitrum technology, settles outside Arbitrum One and Arbitrum Nova. Under the Arbitrum Expansion Program, such chains return 10% of net protocol revenue to the Arbitrum ecosystem. That structure directly ties Robinhood Chain’s growth to Arbitrum DAO income.

Arbitrum DAO Posts $6.19 Million in First-Half Income

Arbitrum DAO generated $6.19 million in income during the first half of 2026, according to the Arbitrum Foundation’s unaudited bi-annual progress update covering the period through June 30. Revenue came from four sources: Arbitrum One transaction fees, Timeboost priority-access auctions, Expansion Program licensing fees, and treasury returns.

Gross margins on protocol revenue exceeded 97%, higher than the more than 90% recorded for full-year 2025. At the end of June the DAO held $125 million in non-ARB assets. The network processed 478 million transactions in the half, representing about 18% of its 2.7 billion lifetime total.

Ma added that, based on July figures, third-quarter income is already tracking to exceed the second quarter by more than 40%.

Robinhood Chain Licensing Fees Drive July Contribution

Robinhood Chain went live on mainnet on July 1. In its first full month it generated $360,000 in Expansion Program licensing fees. That amount accounted for 35% of Arbitrum DAO’s income for July.

The chain had previously supported tokenized stocks on Arbitrum One before launching its own network. Its public testnet recorded more than 200 million transactions prior to mainnet. Day-one partners included Alchemy, BitGo, Chainlink and Uniswap. The network also ranked first in Electric Capital’s developer activity ranking less than two weeks after launch.

Record Fee Day and Ongoing Activity

The $3.75 million fee total on September 1 represented an all-time high for Robinhood Chain and the fourth consecutive day of record daily fees in some data sets. Cumulative fees since launch have surpassed $13 million in roughly two months of operation in certain reports.

At the 10% share rate, the September 1 fees translated into roughly $375,000 to $377,000 flowing to the Arbitrum ecosystem that day. Of the 10% allocation, reports indicate an 8% portion directed to the Arbitrum DAO treasury and 2% to a developer fund.

Decentralized exchange volume on the chain exceeded $1.5 billion on the record day, with total value locked clearing $750 million. The network’s EVM compatibility and focus on tokenized real-world assets, including stock tokens, have supported rapid early adoption.

Broader Ecosystem Metrics

In the first half of 2026 the wider Arbitrum ecosystem recorded average monthly stablecoin transfer volume exceeding $70 billion. Arbitrum ranked first by number of tokenized real-world asset deployments, though Ethereum continued to lead by total value locked in that category.

The Expansion Program functions as a licensing framework in which teams deploy chains on Arbitrum technology, pay a share of net protocol revenue, and gain access to the established network’s security and interoperability features. Robinhood Chain’s July contribution and September fee spike illustrate how external chain activity is beginning to diversify Arbitrum DAO’s income beyond native transaction fees on Arbitrum One.
