Offchain Labs has become the center of a heated dispute over the fee structure of Robinhood Chain. The disagreement involves Solana's founders and raises a broader question: should applications that build their own network keep the bulk of the revenue it generates? The exchange is one of the most visible clashes yet over how value should flow when a mainstream financial application moves onto its own blockchain.

Steven Goldfeder, co-founder of Offchain Labs, and Anatoly Yakovenko, co-founder of Solana, took their debate public on X. At issue is Robinhood Chain, which launched in July on the Arbitrum Orbit network, an Ethereum-based blockchain where ETH serves as the gas currency.

Goldfeder posted:

I have a ton of respect for @toly but this is a ridiculous take. On Arbitrum, Robinhood keeps 90% of gas fees. On Solana they would retain 0 and any gas fees they subsidized would come out of pocket. Robinhood chose Arbitrum so they could be a landlord and not a tenant. — Steven Goldfeder (@sgoldfed) September 5, 2026 (https://x.com/sgoldfed/status/2096309115844702213)

Robinhood Chain Fee Model Draws Attention

Robinhood Chain operates with block times of 100 milliseconds and has quickly become a busy network. At its peak in early September, it processed roughly 10.4 million transactions daily, with daily fees totaling about $4.22 million. Average transaction fees rose to approximately $0.40 during periods of network congestion.

These figures have put Robinhood's fee system under scrutiny. Yakovenko criticized it on September 3–4, arguing that it allows the operator to profit from rising transaction costs caused by congestion. His concern is that this creates a fundamentally different incentive from that of blockchain technology, which primarily aims to keep costs low. If an application earns more when fees are higher, the motivation to reduce costs weakens. At stake is how a retail trading platform's millions of customers experience blockchain-based services, since fee levels on the chain ultimately affect what those users pay when they interact with it.

Offchain Labs Defends Arbitrum's Approach

Responding to the criticism, Steven Goldfeder pointed to the revenue-sharing mechanism governing Robinhood Chain. Under the agreement, 90% of revenue goes to Robinhood, while 10% is allocated to the Arbitrum network.

According to Goldfeder, this arrangement gives developers greater control over the economics of their blockchain. Companies can run their own infrastructure and earn revenue based on their own operations. For Offchain Labs, Robinhood Chain serves as a concrete example that a blockchain can sustain a usage-based business model.

Two Different Models for Blockchain Economies

The debate ultimately reflects the structural difference between Arbitrum and Solana. The Arbitrum Orbit model supports an app-chain system in which companies operate their own blockchains and retain a significant share of the income those chains generate. This design is part of a broader app-chain trend, in which projects launch dedicated chains to customize performance, fees, and economics rather than competing for space on a shared network.

Solana takes a different approach: it is a high-throughput network designed to process large volumes of transactions at low cost. Unlike Robinhood Chain, transaction fees are not collected directly by the application but by validators and the network as a whole.

This distinction has made Robinhood Chain a notable case study for the future of blockchain infrastructure. Offchain Labs argues that greater revenue control benefits application developers, while Solana emphasizes network-level economics and low transaction prices.

Robinhood Chain Faces a Key Test

Robinhood Chain now faces the question of whether it can sustain high transaction volumes without elevated fees driving users away. If user behavior remains stable despite occasional higher fees, the model will strengthen the case for application-specific blockchains. Conversely, if users prove highly sensitive to transaction costs, Robinhood's pricing model may come under increased scrutiny. Watchpoints going forward include daily transaction and fee levels on the chain, whether congestion-driven fee spikes recur, and whether other large applications follow Robinhood's app-chain route or deploy on shared networks like Solana.

The dispute between Offchain Labs and Solana therefore extends beyond a single blockchain, addressing a wider question about who should capture the value created by blockchain growth.
