‘Landlord, Not a Tenant’: Arbitrum and Solana Founders Just Fought Publicly Over Robinhood’s Chain Fees — and the Numbers Explain Why

Two of the biggest names in blockchain had a very public argument this weekend over a simple question with a lot of money attached: when Robinhood built its own chain, who should keep the fees?

By David Chen | September 6, 2026

On September 5 and 6, Steven Goldfeder, co-founder of Offchain Labs (the company behind Arbitrum), and Anatoly Yakovenko, co-founder of Solana, traded barbs on X over why Robinhood built its blockchain on Arbitrum technology instead of simply running its applications on Solana. The backdrop: Robinhood Chain just recorded 6.04 million USD in daily transaction fees — and under its deal with the Arbitrum ecosystem, Robinhood keeps the overwhelming majority of that.

The Hook: A Record Fee Day Lit the Fuse

Robinhood Chain has become one of the hottest networks in crypto almost overnight, driven by memecoin trading, token launches and decentralized exchange activity — with apps like GMGN, Pons and Uniswap generating much of the volume. In its latest 24-hour reporting period, the network collected a record 6.04 million USD in transaction fees and retained roughly 5.44 million USD after expenses and its revenue-sharing obligation, according to data cited by crypto.news. Over seven days, the chain generated about 20.33 million USD in revenue.

That money is the prize. And it is why the founders of two competing ecosystems are arguing about who deserves it.

The Evidence: How the 90 Percent Deal Actually Works

Goldfeder’s claim — that Robinhood “keeps 90%” — refers to the Arbitrum Expansion Program, and the details matter. Under the arrangement:

• Robinhood Chain sends 10 percent of its net protocol revenue to the broader Arbitrum ecosystem.
• Eight percentage points of that go to the Arbitrum DAO treasury.
• Two percentage points fund the Arbitrum Developer Guild, which backs ecosystem builders.
• Net revenue is calculated after network expenses — including the cost of posting transaction data to Ethereum.

So it is not 90 percent of every gross fee users pay; it is 90 percent of what remains after costs. Still, the recent numbers show the chain keeping roughly 90 percent after expenses and allocations — a striking outcome for a network that is only months into its existence.

The Core Conflict: Landlord or Tenant?

Yakovenko’s argument focuses on the application layer. In his view, Robinhood did not need its own chain at all: it could have deployed on Solana, subsidized transaction costs for its customers, and charged users through its own interface — commissions, spreads, subscriptions or service fees. No expensive Layer 2 network to operate.

Goldfeder’s rebuttal, in what is already the most-quoted line of the debate: “Robinhood chose Arbitrum so they could be a landlord and not a tenant.” On Solana, he argued, Robinhood would retain none of the network’s fee revenue, and any gas fees it subsidized would come straight out of its own pocket.

Here is the crux for DeFi users: app-layer fees only capture activity that flows through Robinhood’s own front door. Third-party wallets, trading bots, decentralized exchanges and launchpads interact with the chain’s contracts directly. If Robinhood were a tenant on Solana, independent activity would enrich Solana validators and stakers — not Robinhood. As the landlord of its own chain, every app on the network, not just Robinhood’s, feeds its revenue.

Market Implications: The Business Model Experiment Everyone Is Watching

If Robinhood Chain sustained its current pace for a full year, it would generate on the order of 1.06 billion USD in annual revenue — though that annualization is only a projection built on an unusually hot, brief period of activity, and it deserves heavy skepticism. The more durable takeaway is structural: the Arbitrum Expansion Program’s revenue-sharing model (10 percent to the ecosystem, 90 percent to the chain operator) is now a proven template that other financial brands may copy when weighing where to build.

For ARB holders, the debate cuts both ways. The DAO treasury’s cut grows with Robinhood Chain’s success, tying Arbitrum’s fortunes to real fee revenue rather than speculation. For Solana supporters, the counterargument is that raw activity and users matter more than any single deal. For context, ether traded near 2,482 USD and solana around 106 USD at the time of this report’s price snapshot.

The Verdict: The Fees Settled the Argument Before It Started

Yakovenko is right that companies can monetize at the application layer without owning infrastructure. But Goldfeder’s landlord analogy explains why Robinhood made the choice it did: when your chain prints millions in daily fees, owning the railroad beats renting space beside it. The real test comes when the memecoin frenzy cools — and we find out whether record fee days were the norm or the honeymoon.
