In the long post released on September 6, 2026, Ignas immediately threw out a set of shocking numbers: on a certain trading day, Robinhood L2 earned about $6 million in fees on its chain, while on the same day, it only paid about $722 to the Ethereum L1 settlement layer. The contrast of 6 million to 722 is not an ordinary income gap, but rather a deliberately magnified comparison—Robinhood and the Arbitrum ecosystem take away the vast majority of cash flow; Robinhood L2 even gives only about 10% of the fees to Arbitrum, keeping the remaining majority for itself, and the meager settlement fees that actually flow to Ethereum L1 are described by multiple media outlets as “insignificant” “crumbs.” Ignas regards this as a model of the Ethereum rollup-centric route: L1 paves the way for L2 through extremely low settlement fees, just like Uber initially built its user base by burning subsidies, pushing up traffic and transaction volume first, and discussing how to make money later. However, when L2 rolls out huge fees on its own ledger and locks value firmly in the hands of applications and operators, what is left for Ethereum L1? Ignas raises a direct question: under this structure of L2 prosperity and L1 only collecting settlement fees, is Ethereum L1 quietly losing its ability to capture direct value?
Contrast of 6 million to 722 dollars
Ignas did not just throw out the phrase “L1 is subsidizing L2” and walk away; he analyzed a day’s earnings from Robinhood L2. On that day, this chain collected about $6 million in fees in its own network, while the cost recorded to Ethereum L1 for settlement was only $722. When the numbers are placed side by side, the structure is immediately exposed: the vast majority of payments come from Robinhood users, remaining in the L2 controlled by Robinhood and circulating, with L1 only involved at the last moment, treated as a cheap and safe “proof space” with a little money paid. As a result, multiple media outlets used the term “crumbs” to describe the direct income Ethereum received from this business, while Ignas views this as a model for value distribution in the L2 era.
Breaking it down further is even more shocking. Robinhood L2 gave about 10% of this $6 million to the Arbitrum ecosystem as a share of earnings for the underlying technology and network, while the vast majority was retained by Robinhood itself, with only a tiny sliver flowing towards Ethereum L1 in the form of compressed data publishing fees. The rollup model allows massive transactions to be executed within L2, only writing the packaged data (such as blobs) back to L1, successfully compressing the gas costs that need to be paid and simultaneously flattening the direct revenue curve of L1—within this design, L2 is the charging window, Arbitrum is the “upstream supplier,” and Ethereum L1 is squeezed to the end of the accounting chain, only capable of proving its economic existence through this type of reduced settlement fee.
Ignas questions Ethereum working for L2
In front of this flattened income curve as a “settlement layer,” Ignas directly presented a striking contrast: on a certain day, Robinhood L2 earned about $6 million in fees, and on the same day only paid $722 in settlement fees to Ethereum L1. Robinhood retained the vast majority of the income on its books, giving about 10% to the Arbitrum ecosystem, while that small piece that actually flows to Ethereum L1 was simply described by the media as “crumbs.” Ignas likened this structure to Uber's early subsidy growth—where the platform burned money madly at low prices for scale, except in Ethereum's version, the “discounts” are the settlement fees of L1, while various L2s sitting at the front desk enjoying high revenues and high growth stories.
What Ignas grasped is not merely the quirky gap of 6 million to 722 dollars, but the longer-term logic of value distribution behind it: under the rollup-centric model, most transactions and fees remain stuck in L2, only throwing the packaged data back to L1, leading to a passive shrinkage of Ethereum L1’s direct economic returns. Supporters may argue that L1's value should be reflected in the value storage and security premium of ETH as an asset, without needing to rely on high fees; however, Ignas's implicit question is, if this pattern continues, L1 could end up being just an open “public ledger,” rather than a foundational asset with strong cash flow that can share growth dividends with L2.
The gamble of turning the execution layer into a settlement layer
From a singular execution layer to a dual structure of “L1 settlement + L2 execution,” Ethereum's roadmap over the years has been paving the way for rollup-centric solutions: L2 handles the vast majority of transactions within their respective networks, only packaging the compressed data on-chain, while L1 relegates to a settlement layer and data availability layer. In other words, the transaction volume originally crammed into the Ethereum mainnet has been systematically diverted, with L1 no longer pursuing to keep every user interaction recorded on its own books, but actively outsourcing execution to L2, trading off lower settlement costs in exchange for overall scalability and ecological size.
The story seen by supporters is quite simple: the real value lies not in the high gas fees for each transaction, but in ETH’s role as collateral asset and value storage tool—so long as all L2s eventually return to Ethereum for settlement, the security premiums and asset status will continuously accumulate, and L1 will not need to rely on “congestion taxes” to make money. However, critics see a different curve: after a large number of transactions and fee migrations to L2, the basic fee income of L1 has been compressed, hedging the profit-sharing space with ecological participants, and its bargaining power is quietly being weakened. In cases like Robinhood L2, where L2 and the upper-level ecosystem take the bulk while Ethereum only receives a settlement “crumb,” this strategy of turning the execution layer into a settlement layer seems more like a gamble on whether the future security premium of ETH can cover the current cash flow yield.
Robinhood and Arbitrum taking a cut from Ethereum
On the day pointed out by Ignas, the approximately $6 million in fees from Robinhood L2 was broken down into an extremely asymmetrical profit-sharing table: about 10% was allocated to the Arbitrum ecosystem as a “platform share” for the technology and community that the chain relies on; the remaining nearly 90% stayed within the Robinhood system, becoming a new source of cash flow for this traditional brokerage after it pivoted to the chain. What was left for Ethereum L1 was just the approximately $722 in fees during the settlement—referred to as “crumbs” by multiple media outlets. The underlying resources that enable this L2 to operate and be packaged by Robinhood as “its own chain” is precisely the final settlement security and data availability provided by Ethereum; all transactions still need to return to this public ledger for stamping confirmation.
This profit-sharing structure puts the incentives of all three parties on display: Robinhood now has sufficient reason to continuously push the proportion of on-chain transactions in its products; for every additional transaction, the vast majority of the fees go into its own pocket; the Arbitrum ecosystem, as the technology and brand provider, can also gain continuous income from that 10% cut, making it profitable to partner with Robinhood to grow the transaction volume of this L2. Only Ethereum L1, which bears the critical functions of security and settlement, can only monetize directly through settlement fees of the magnitude of about $722, placing it in a passive position as it can merely hope that the value storage and security premium of ETH as an asset will make up for this gap in the longer term.
Ethereum's next step left to the market
The approximately $6 million in fees earned by Robinhood L2 on a single day and the roughly $722 paid to Ethereum L1 as settlement fees is just an extreme sample of the current landscape: most trading executions and fee revenue are intercepted by the L2 network, with L1 as the settlement layer and data availability layer, only receiving what multiple media outlets call “crumbs.” This clearly puts pressure on Ethereum L1’s direct cash flow, yet it also nails it more firmly into the position of a “public settlement layer”—security, consensus, and ledger are more akin to an infrastructure service rather than a high-profit charging machine. Going forward, Ethereum may only have two paths to take: one is to follow the narrative long emphasized by supporters, viewing ETH as the cornerstone for value storage and network security, allowing L1’s value to be more reflected indirectly through asset prices and security premiums, rather than hoping to extract more taxes from every transaction like those of Robinhood L2; the other is to acknowledge the current weakness in value capture and attempt to adjust the fee structure and the L1-L2 profit-sharing mechanism in the future, allowing the settlement layer to gain a more pronounced income distribution without stifling scalability. Ignas's questioning has laid this contradiction on the table, and the discussions within the community and among researchers regarding the value distribution between L1 and L2 are still far from reaching a consensus. After more instances of “Robinhood L2” appear, whether the market will force a value reconstruction through capital flows and project choices or whether Ethereum will continue to bet on the long-term premium of ETH itself to hedge against thin cash flows will ultimately be answered by time and price.
