Users of Robinhood Chain paid a record transaction fee of US$3.75 million on September 1. This allowed the network, which had only been launched for two months, to surpass the Ethereum Main Network and Base on that day, and every dollar spent earned a revenue share for the underlying technology stack it runs, Arbitrum.
Decentralized Exchange (DEX) trading volume exceeded US$1.5 billion, and the total locked position value exceeded US$750 million.
US$3.75 million is the highest in history for the chain since it was launched on the main network on July 1. Robinhood Chain surpassed the Ethereum main network and Base that day.
On September 1, the transaction volume of decentralized exchanges exceeded US$1.5 billion, also setting a record. The total locked position value is slightly over $750 million.
Robinhood Chain's public test network had processed more than 200 million transactions before it was launched on the main network. Before launching his own chain, Robinhood had been issuing tokenized shares on Arbitrum One.
Robinhood Chain ranked first in Electric Capital's developer activity ranking less than two weeks after its launch. On July 21, Alchemy CEO Nikil Viswanathan announced the achievement on X.
The chain's EVM compatibility and first-day partners provide developers with a familiar build environment. These partners include Alchemy, BitGo, Chainlink and Uniswap.
Robinhood launched the Mainnet during a keynote speech in London on July 1.
Johann Kerrat, general manager of Robinhood's cryptocurrency and international business, said at the time: "We combine the best parts of traditional finance and DeFi."
License fees of $360,000 in July accounted for 35 percent of DAO revenue.
Arbitrum Expansion Plan is the mechanism that links Robinhood's expenses to Arbitrum Balance Sheet. Chains that run on the Arbitrum stack but settle outside Arbitrum One or Arbitrum Nova are required to return 10% of their net agreement revenue to the Arbitrum ecosystem.
Robinhood Chain's license fees for July (its first full month) totaled $360,000. This figure accounted for 35% of Arbitrum DAO's monthly revenue.
The expansion plan is similar to a franchise. The team launches its own chain on Arbitrum's technology, pays license fees, and gains the security and interoperability of a mature network.
DAO generated revenue of US$6.19 million in the first half of 2026. The four sources are Arbitrum One transaction fees, Timeboost priority access auction, expansion plan license fees, and treasury revenue.
The gross profit margin on agreement revenue exceeds 97%, up from more than 90% in 2025. As of the end of June, the DAO's treasury held $125 million in non-ARB assets.
This chart is from the Arbitrum DAO financial panel in the first half of 2026 progress update released by the Arbitrum Foundation on September 2, 2026.
Robinhood Chain was launched after the report window closed. The impact is reflected in the numbers for July and beyond, rather than in the total data for the first half of the year.
Brendan Ma, head of investment strategy at the Arbitrum Foundation, said: "Amid the industry's overall market downturn, ecosystem growth has accelerated since the end of the first half."
Regarding July data, Ma said that revenue in the third quarter is already expected to increase by more than 40% from the second quarter.
