A debate over Robinhood Chain's network economics expanded in early September into a broader dispute about how blockchains should fund long-term growth. BNB Chain Executive Director of Growth Nina Rong argued that sustainable business models should now take priority, shifting attention from immediate transaction costs to the financial structures supporting network development.
The discussion began after Solana co-founder Anatoly Yakovenko remarked that Robinhood's 10% revenue share with Arbitrum could have covered Solana transaction fees multiple times over, potentially allowing Robinhood to offer gasless transactions. Offchain Labs co-founder Steven Goldfeder responded by noting that on Arbitrum, Robinhood retains 90% of gas fees, while on Solana they would retain none and any subsidized fees would come out of pocket.
Revenue Sharing as Infrastructure Funding
Robinhood Markets launched its dedicated Ethereum layer-2 network on July 1 using the Arbitrum Platform. Under the Arbitrum Expansion Program license, Robinhood Chain returns 10% of protocol net revenue, with 8% going to the DAO treasury and 2% funding the Arbitrum Developer Guild.
This arrangement illustrates how blockchain infrastructure providers can earn recurring revenue when companies build dedicated networks using their technology. 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.
Shifting Industry Priorities
Rong argued that blockchain foundations have spent much of the past five years distributing grants, making investments, and cutting gas fees. She contended that sustainable commercial structures now matter more than further transaction-cost reductions.
"The real priority of all blockchains today is finding sustainable business model that feeds back into its tech and growth," Rong wrote, noting that business models can take the form of gas fees, revenue sharing, and other commercial agreements.
Network Activity and Competition
Applications on Robinhood Chain generated $2.66 million in 24-hour revenue as of August 31. Trading terminals and token launches, including GMGN, Pons, and Uniswap, produced about 88% of that day's total, rather than the tokenized equities the chain was built around.
Competition with Coinbase's Base has increasingly centered on user distribution and recurring activity rather than transaction prices alone. Layer-2 networks process activity away from a base blockchain before using it for settlement, allowing operators to adjust fees, performance, and commercial terms. Tokenized equity trading reached nearly $3 billion in weekly volume during August, with Robinhood Chain, BNB Chain, and Solana handling significant portions of that volume.
