Key Takeaways
- Nina Rong said lower gas fees are no longer the industry’s priority.
- Robinhood retains 90% of protocol net revenue while sharing 10% with Arbitrum.
- The dispute exposed competing approaches to funding blockchain growth.
Robinhood Fee Debate Moves Beyond Transaction Costs
A debate over Robinhood Chain’s network economics expanded on Sept. 6 into a wider dispute about how blockchains should fund long-term growth. BNB Chain Executive Director of Growth Nina Rong argued in a post on X that sustainable business models should now take priority, shifting attention from the immediate cost of transactions to the financial structures supporting network development.
The exchange began after Solana co-founder Anatoly Yakovenko remarked on Sept. 4 that Robinhood’s 10% revenue share with Arbitrum could have covered Solana transaction fees four times over, potentially allowing Robinhood to offer gasless transactions. Offchain Labs co-founder Steven Goldfeder 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 illustrates how blockchain infrastructure providers can earn recurring revenue when companies build dedicated networks using their technology. An ArbitrumDAO factsheet states that Robinhood Chain returns 10% of protocol net revenue under the Arbitrum Expansion Program license, with 8% going 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 built for tokenized assets, trading, and decentralized finance. The company’s mainnet announcement described the network as natively connected to its onchain users and announced alongside products such as Stock Tokens, lending, and perpetual futures.
The difference between building a chain and operating an application shapes where transaction revenue ultimately goes. Robinhood’s public mainnet rollout allowed the company to retain most of the network’s economics while compensating Arbitrum for the underlying technology, rather than directing all network fees to an independent blockchain.
Blockchains Compete Over Revenue, Users, and Growth
Rong argued that blockchain foundations have spent much of the past five years distributing grants, making investments, and cutting gas fees. Doing that for another five years requires solid commercial structure for blockchain companies, she added.
“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, noting:
“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 produced about 88% of that day’s total, a mix weighted toward trading terminals and token launches rather than the tokenized equities the chain was built around.
Competition with Coinbase’s Base has increasingly centered on user distribution and recurring activity, not transaction prices alone. Base has answered with the reach it accumulated across nearly three years rather than matching Robinhood Chain’s daily users or trading volume.
Layer-2 networks generally process activity away from a base blockchain before using it for settlement, allowing operators to adjust fees, performance, and commercial terms. <a href="https://www.bitcoin.com/get-started/blockchain-tech/layer-2s-scaling/bitcoin-layer-2-solutions/” rel=”nofollow noopener” target=”_blank”>Layer-2 infrastructure can reduce transaction costs and expand capacity, but Rong’s argument places the next competitive test on whether those networks can convert activity into dependable funding for technology and network growth.
