The dispute around Robinhood Chain’s economics widened on Sept. 6. What started as a comment about transaction fees became a broader argument about how blockchains should pay for their own development. In a post on X, Nina Rong, Executive Director of Growth at BNB Chain, said network operators should focus on sustainable business models. The cost of each transaction, she suggested, is no longer the main issue.
From fees to revenue sharing
The exchange began after Solana co-founder Anatoly Yakovenko calculated on Sept. 4 that Robinhood’s revenue share arrangement with Arbitrum could have covered Solana transaction fees four times over. That amount, he said, might have been enough for Robinhood to offer gasless transactions.
Steven Goldfeder, co-founder of Offchain Labs, pushed back in a separate X post. His point was about control. On Arbitrum, Robinhood keeps most gas fees. On Solana, it would receive nothing and any fee subsidies would come out of the company’s pocket. Robinhood, he said, chose Arbitrum so it could act more like a landlord than a tenant.
An ArbitrumDAO factsheet explains the revenue mechanism. Robinhood Chain returns 10% of protocol net revenue under the Arbitrum Expansion Program license. The DAO treasury receives 8%. The remaining 2% goes to the Arbitrum Developer Guild.
Robinhood Markets introduced its Ethereum layer-2 network on July 1. It runs on Arbitrum Platform. The exchange described the network as a space built for tokenized assets, trading, and decentralized finance. Products announced at mainnet include Stock Tokens, lending, and perpetual futures.
A different view on blockchain funding
Rong’s response frames the debate in wider terms. She argued that blockchain foundations have spent much of the last five years giving out grants, making investments, and lowering gas fees. That approach, she said, cannot continue for another five years without a stronger commercial structure.
She acknowledged that lowering gas fees may be good for individual apps. But she called it no longer the highest priority for the industry as a whole. The real task, in her view, is finding a business model that puts money back into technology and growth. That model can take different forms, including gas fees, revenue share agreements, or other commercial deals.
What the early revenue data shows
Robinhood Chain’s early revenue data supports some of the pressure behind that argument. On Aug. 31, applications on the chain brought in about $2.66 million in 24-hour revenue. That was more than Ethereum and Hyperliquid L1 reported for the same day. The bulk came from three apps: GMGN, Pons, and Uniswap contributed about 88% of the total. The mix skews toward trading terminals and token launches rather than the tokenized equity products the chain was meant to highlight.
Competition with Coinbase’s Base now seems less about transaction prices and more about user distribution. Base has been running for close to three years and tends to lean on accumulated reach. Robinhood Chain has drawn attention for daily users and trading volume, but Rong’s point suggests that user numbers alone will not decide the next round of competition.
Can layer-2 activity finance growth?
Layer-2 networks operate away from a main blockchain and use it mainly for settlement. That setup gives operators room to change fees, improve performance, and set their own commercial terms. It can cut costs and raise capacity. The open question is whether those networks can turn activity into steady funding for future development. Rong’s comment pushes that question to the center of the debate. Robinhood Chain’s model, with its split between app revenue and Arbitrum licensing, is one possible answer. Whether it holds up over time may define how blockchain platforms talk about growth.
