Robinhood Chain processed $1.595 billion in decentralized exchange volume on September 1, jumping 61% from a record of $989 million set just four days earlier, according to DefiLlama data. The two-month-old Layer 2 network now handles more daily DEX activity than several Ethereum scaling solutions that have been operating for years.
The volume surge pushed Robinhood Chain past Ethereum itself in daily fee revenue on the same day, with users paying $3.75 million in transaction fees, data tracked by The Block shows. Most of that volume came from memecoin speculation rather than the tokenized stock trading that Robinhood originally pitched as the chain’s primary use case.
An analysis of the first $9 billion in Robinhood Chain activity found that more than 80% came from memecoin trading. The chain’s rapid growth has been fueled by a 90-day gas subsidy that covers all transaction fees, a promotion that ends September 29. That free-gas model is the single biggest variable in whether these numbers hold into the fall.
Growth No Other Layer 2 Matched
Robinhood Chain’s total value locked surged from $4 million in June to roughly $1.4 billion by late August. No Ethereum Layer 2 has posted that kind of growth curve at the same stage. Cumulative DEX volume crossed $47 billion by mid-August, a total most competing networks took years to reach.
The chain set two all-time highs in four days. DEX volume peaked near $878 million on July 12 during the first memecoin wave, then fell as much as 72% into early August before rebounding sharply. The September 1 record of $1.595 billion more than doubled the earlier peak.
Trading is dominated by Uniswap, which processes most of the DEX activity on the chain. Retail traders have been drawn by Robinhood’s built-in user base of millions of brokerage customers, many of whom already have funded accounts. The combination of an established fiat on-ramp and zero transaction costs created conditions for rapid volume growth that organic crypto-native chains struggled to match.
Robinhood launched the chain as an Ethereum Layer 2 using Arbitrum’s rollup technology in early July. The network was designed to let users trade tokenized versions of stocks alongside crypto assets, positioning Robinhood as a bridge between traditional equities and decentralized finance. In practice, memecoins drove nearly all the early activity.
The stock-token thesis has not panned out yet. While Robinhood does offer tokenized versions of select stocks on the chain, most traders are using the platform to speculate on newly launched memecoins. Several of those tokens have generated controversy. The chain’s FAMI token, paired with the Nasdaq-listed stock ticker of Chinese mushroom seller Farmmi, triggered a 350% surge in Farmmi shares on September 2 after traders conflated the on-chain token with the actual equity. Robinhood said the FAMI token on its chain is not an official stock token.
The September 29 Cliff
The central question hanging over Robinhood Chain is whether it can sustain these numbers once the gas subsidy expires. The promotion has made every transaction free for users, effectively subsidizing memecoin speculation at Robinhood’s expense. Transaction counts, DEX volume, and user totals have never been observed without the subsidy. October data will reveal how much of the early activity reflects genuine demand versus promotional incentives.
For comparison, Base, the Layer 2 operated by Coinbase, took over a year to reach similar daily DEX volume levels. Arbitrum, the second-largest Ethereum Layer 2 by total value locked, typically processes $300 million to $500 million in daily DEX volume. Neither chain offered fee subsidies at the scale Robinhood has deployed.
The risk is that Robinhood Chain’s user base is more mercenary than loyal. When Base launched its own fee subsidies in 2024, daily active users spiked and then fell by more than half once the promotion ended. If Robinhood Chain follows the same pattern, its current volume numbers could look like a peak rather than a starting point.
Robinhood has not disclosed the cost of the gas subsidy or whether it plans to extend the promotion beyond September 29. A company spokesperson declined to comment on future plans for the chain’s fee structure. The lack of clarity has not stopped crypto analysts from speculating that the company may quietly extend the subsidy if volumes drop sharply.
Arbitrum Benefits on the Sidelines
The chain’s success has benefited the broader Arbitrum ecosystem even as Robinhood captures most of the attention. Robinhood Chain settles through Arbitrum’s technology under the Arbitrum Expansion Program, which requires chains settling outside Arbitrum One and Nova to return 10% of net protocol revenue. In July, the first month Robinhood Chain operated on mainnet, licensing fees brought in $360,000 and accounted for 35% of ArbitrumDAO’s total income.
ARB, Arbitrum’s native token, jumped 25% on September 2 after the Robinhood Chain fee data circulated. The token had traded near $0.06 earlier in the summer. The Arbitrum Foundation also reported $6.19 million in first-half income across four revenue lines, with gross margins on protocol revenue exceeding 97%.
For the Ethereum ecosystem, Robinhood Chain’s growth validates the Layer 2 roadmap that has been central to the network’s scaling strategy. But it also raises questions about whether the winning Layer 2 will be one built by crypto-native teams or by traditional financial platforms with existing user bases. Robinhood’s ability to funnel millions of brokerage users onto a blockchain represents a distribution advantage that no crypto startup can match.
