Robinhood Chain Fee Debate Expands to Solana, Arbitrum and BNB Chain

The Fee Debate Moves Beyond Transaction Costs

A dispute over Robinhood Chain’s network economics broadened on Sept. 6 into a larger argument about how blockchains should finance their long-term growth. Nina Rong, Executive Director of Growth at BNB Chain, argued in a post on X that sustainable business models deserve priority now, shifting the conversation away from the immediate cost of transactions and toward the financial structures that fund network development.

The exchange traces back to Sept. 4, when Solana co-founder Anatoly Yakovenko observed that Robinhood’s 10% revenue share with Arbitrum could have covered Solana transaction fees four times over — enough, potentially, for Robinhood to offer gasless transactions. Solana’s design keeps per-transaction fees fractions of a cent, which is why the comparison underscores how small base-layer costs are relative to the revenue Robinhood Chain’s applications now generate. Steven Goldfeder, co-founder of Offchain Labs, responded on X:

“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.”

Revenue Sharing Turns Infrastructure Into a Business

The arrangement shows how blockchain infrastructure providers can earn recurring revenue when companies build dedicated networks on top of their technology. It also reflects a broader shift in the layer-2 landscape, where rollup providers such as Arbitrum, OP Labs, and others increasingly license their stacks to enterprises and financial firms rather than competing only for public-network users. According to an ArbitrumDAO factsheet, Robinhood Chain returns 10% of protocol net revenue under the Arbitrum Expansion Program license, with 8% flowing to the DAO treasury and 2% funding the Arbitrum Developer Guild.

Robinhood Markets (Nasdaq: HOOD) launched its dedicated Ethereum layer-2 network on July 1 using the Arbitrum Platform, giving the brokerage control over an environment designed for tokenized assets, trading, and decentralized finance. The company’s mainnet announcement described the network as natively connected to its onchain users and was unveiled alongside products such as Stock Tokens, lending, and perpetual futures.

The distinction between building a chain and operating an application determines where transaction revenue ultimately lands. Because Robinhood built and rolled out its own mainnet, the company retains most of the network’s economics while compensating Arbitrum for the underlying technology — rather than routing all network fees to an independent blockchain.

Blockchains Compete Over Revenue, Users, and Growth

Rong contended that blockchain foundations have spent much of the past five years distributing grants, making investments, and cutting gas fees. Sustaining that approach for another five years, she added, requires blockchain companies to have a solid commercial structure.

“Zooming out on the debate of ‘what’s best for Robinhood’, I really want to point out further lowering gas fee is no longer the highest priority of the blockchain industry,” Rong wrote, adding:

“The real priority of all blockchains today is finding sustainable business model that feeds back into its tech and growth. The business model can be gas fee, rev share and other forms of commercial agreement.”

Trading Apps Generate Most of the Chain’s Fees

Applications on Robinhood Chain generated $2.66 million in 24-hour revenue as of Aug. 31, ahead of Ethereum and Hyperliquid L1 on the same measure. GMGN, Pons, and Uniswap accounted for roughly 88% of that day’s total — a mix weighted toward trading terminals and token launches rather than the tokenized equities the chain was originally built around.

Competition with Coinbase’s Base has increasingly focused on user distribution and recurring activity rather than transaction prices alone. Base has responded with the reach it accumulated across nearly three years, rather than by matching Robinhood Chain’s daily users or trading volume.

Layer-2 networks generally process activity off a base blockchain before using it for settlement, which lets operators adjust fees, performance, and commercial terms. While layer-2 infrastructure can lower transaction costs and expand capacity, Rong’s argument frames the next competitive test differently: whether these networks can convert activity into dependable funding for technology and network growth. How Robinhood Chain’s revenue mix evolves — and whether future enterprise chains adopt similar revenue-sharing licenses — will offer an early read on whether that model can scale across the industry.
