Robinhood Chain vs Solana debate sparked on September 6. Offchain Labs co-founder Steven Goldfeder and Solana co-founder Anatoly Yakovenko exchanged competing views.
They argued over why Robinhood built its blockchain using Arbitrum technology. The alternative was operating applications directly on Solana.
Why the Robinhood Chain vs Solana debate matters
Goldfeder argued that Robinhood can retain roughly 90% of its chain revenue. This is possible under the Arbitrum Expansion Program. A Solana-based application would pay network fees. It would not receive the underlying chain’s revenue.
“Robinhood chose Arbitrum so they could be a landlord and not a tenant,” Goldfeder wrote.
His comment responded to Yakovenko’s position. Yakovenko said Robinhood could subsidize Solana transaction fees. It could charge users through its own application instead.
The debate followed a sharp rise in Robinhood Chain activity. The network recently collected $6.04 million in daily transaction fees. It retained about $5.44 million after expenses and Arbitrum revenue-sharing.
Robinhood keeps 90% of net revenue, not gross fees
Goldfeder’s 90% figure reflects the Arbitrum Expansion Program’s share. It should not be interpreted as retaining 90% of every gross fee.
Under the program, Robinhood Chain sends 10% of net protocol revenue to Arbitrum. Eight percentage points go to the Arbitrum DAO treasury. Two percentage points fund the Arbitrum Developer Guild.
Net revenue is calculated after relevant network expenses. These include the cost of posting transaction data to Ethereum. Robinhood’s actual retained amount depends on several factors. These include gross transaction fees and Ethereum data costs. Infrastructure expenses and the Arbitrum payment also factor in.
The arrangement has already produced measurable results. Robinhood Chain collected a record $6.04 million in transaction fees. This was during its latest 24-hour reporting period. It retained approximately $5.44 million. The figures show the network keeping about 90% after costs.
The network also generated $20.33 million in revenue over seven days. Maintaining that rate for a full year would produce approximately $1.06 billion. Such annualization is only a projection nevertheless. It is based on a brief period of unusually high activity.
The latest Robinhood Chain fee record followed rapid growth in memecoin trading. Token launches and DEX volume also contributed. GMGN, Pons, and Uniswap accounted for much of the application activity.
Yakovenko says applications can collect fees on Solana
Yakovenko’s argument focuses on the application layer. Robinhood could deploy its services on Solana and subsidize transaction costs. It could charge customers through its interface. This avoids the expense of operating a separate Layer 2 network.
This approach could work for transactions through Robinhood’s application. Brokerages can charge commissions and spreads. They can also charge subscription or service fees. They do not need to control the underlying blockchain.
Goldfeder countered that this model would not capture value from outside activity. Third-party wallets and trading bots can interact directly with blockchain contracts. Decentralized exchanges and token launchpads can also do this.
Robinhood would pay to subsidize its customers’ transactions on Solana. Nevertheless, it would receive none of the network fees from independent users. Solana validators and stakers would receive those fees instead.
On Robinhood Chain, the company operates the sequencing infrastructure. This allows it to collect transaction fees from activity across the chain. This includes transactions that bypass Robinhood’s front end.
Recent data supports Goldfeder’s point about outside activity. Pons and GMGN have become large contributors to Robinhood Chain’s traffic. Many transactions from those applications do not originate through Robinhood’s brokerage interface.
Robinhood Chain still pays Ethereum and Arbitrum
Robinhood does not retain all the value generated by its blockchain. Robinhood Chain is an Ethereum Layer 2 using Arbitrum Orbit. It is not an independent Layer 1.
The network uses ETH as its native gas token. It posts transaction data to Ethereum using blobs. Each transaction includes an execution component. There is also a data-availability component.
The L2 execution fee covers computation on Robinhood Chain. The L1 data fee pays for publishing transaction information to Ethereum. Both components are bundled into the amount presented to users.
Robinhood also pays the Arbitrum ecosystem’s 10% share of net protocol revenue. The “landlord” description refers to Robinhood’s control over its own chain. It does not mean complete independence from outside infrastructure.
Gas subsidies complicate the revenue comparison
Robinhood launched its chain with a 90-day gas subsidy. This applies to transactions through Robinhood Wallet. The subsidy expires on September 29.
The promotion means eligible wallet users do not directly pay gas. Robinhood covers those costs. Nevertheless, the subsidy does not necessarily cover every transaction across the network.
Goldfeder argued that much of Robinhood Chain’s activity now occurs beyond the Robinhood front end. The company can collect fees from those transactions because it operates the chain.
Robinhood Chain’s activity increased rapidly during the subsidy. Its daily DEX volume recently reached approximately $1.71 billion. Total value locked in native protocols stood near $1.17 billion.
The network has also exceeded Solana in daily chain revenue during some periods. Direct comparisons require caution nevertheless. The networks have different cost structures and subsidy models. Fee markets and validator arrangements also differ.
The fee debate will become clearer after Sept. 29
The first major test arrives when the gas subsidy expires. Post-subsidy data will show how many Robinhood Wallet users continue transacting. They must pay their own network costs when that happens.
It will also show whether independent activity remains strong. Pons, GMGN, Uniswap, and other applications have contributed heavily to fee growth.
A Bitquery investigation found Robinhood Chain’s gas price increased roughly 25-fold within 11 days. The report attributed much demand to a limited group of heavily active wallets.
This concentration creates uncertainty over revenue sustainability. A decline in activity from several large addresses could reduce fees. This could happen even if total user numbers continue rising.
Robinhood has not publicly announced whether it will extend the subsidy. It also has not disclosed how network revenue will appear in financial reporting.
There was no verified movement in HOOD, SOL, ETH, or ARB from the founders’ exchange. Linking broader market fluctuations to their comments would be speculative.
The commercial question remains whether owning a Layer 2 produces more value. Deploying an application on an existing Layer 1 is the alternative. Robinhood Chain’s first unsubsidized operating period will provide the clearest evidence.
