Robinhood Chain reportedly crossed $100 billion in cumulative decentralized exchange (DEX) trading roughly 100 days after its July 1 mainnet launch. Reports attribute much of the rapid rise to a September surge: one cited more than $53 billion in DEX trades that month.
6 But October’s slower trading pace points to a more cautious conclusion: cumulative volume shows how much was traded, not whether the activity is durable or broadly adopted.
A fast milestone, led by a concentrated surge
Robinhood Chain is described in reporting as an Arbitrum-based layer-2 network. Its $100 billion milestone arrived about three and a half months after mainnet launch.

September was a major contributor. One report put that month’s DEX volume above $53 billion, while another characterized the milestone as arriving after an exceptional month.

8 These figures support the broad picture of a sharp burst of trading, though the reports do not provide enough detail here to reconcile every monthly total or establish what share came from particular token categories.
Cumulative trading volume is a measure of turnover, not the amount of money deposited on the chain, the number of distinct people trading, or revenue earned. The available reporting supports the volume milestone, but does not substantiate the separate claim that Robinhood Chain led layer-2 networks in daily active traders. Those measures should not be treated as interchangeable.
October’s pace was slower—and fee capture matters
The October 1–13 figures reported by Memeburn show about $13.2 billion in DEX volume, or roughly $1.02 billion per day. The same report said that pace was 46% below September’s average.
8 That is a meaningful slowdown after the month that helped drive the cumulative total upward.
The report also listed $41.9 million in app fees for October 1–13, equivalent to about $0.32 per $100 traded. For comparison, its July figures were $110.7 million in fees on $15.3 billion of DEX volume, or $0.72 per $100.
8 These figures suggest that volume alone may overstate the economic value of activity: fee generation depends not only on how much is traded, but also on how much revenue trading apps capture.
What the milestone does—and doesn’t—say about sustainability
The reported data establish rapid growth and a sharp October slowdown; they do not settle whether activity will persist. Cumulative volume keeps rising when trades occur, even if the daily pace is declining. It also does not, by itself, show how many traders are returning, how activity is distributed across applications, or whether fee income can support the ecosystem over time.
Robinhood’s third-quarter earnings event is scheduled for October 27.
45 For assessing the chain’s durability, useful signals will include whether trading activity and fee generation hold up beyond the September spike, and whether growth is spread across different kinds of use rather than concentrated in a brief burst.
The clearest takeaway is therefore mixed: Robinhood Chain reached a striking DEX-volume milestone quickly, but October’s lower daily pace and July-to-October decline in fees per dollar traded are reasons not to equate $100 billion in turnover with proven, lasting adoption.
