BNB Chain Executive Director of Growth Nina Rong said blockchains should focus on sustainable commercial models rather than further reductions in gas fees, arguing that recurring revenue is needed to reinvest in technology and growth. Her Sept. 6 comments followed a dispute over Robinhood Chain’s economics, after Solana co-founder Anatoly Yakovenko said Robinhood’s 10% revenue share with Arbitrum could have funded Solana transaction fees four times over. Offchain Labs co-founder Steven Goldfeder said Robinhood retains 90% of gas-fee revenue on Arbitrum, while a Solana deployment would leave the company to cover any transaction subsidies itself. Robinhood Markets launched its Arbitrum-based Ethereum layer-2 network on July 1 and returns 10% of protocol net revenue under its license, with 8% allocated to the ArbitrumDAO treasury and 2% to the Arbitrum Developer Guild. Applications on the network generated $2.66 million in 24-hour revenue as of Aug. 31, led largely by trading and token-launch applications.
