Robinhood Chain transaction costs have reached roughly $0.40 on average, prompting Solana co-founder and Solana Labs chief executive Anatoly Yakovenko to criticize the network’s congestion-based fee model. Data showed the chain generated $4.22 million from about 10.4 million transactions in a single day, while its current median cost of $0.24 ranked highest among 27 tracked chains. Yakovenko argued that Robinhood should monetize its frontend through a 50-to-80-basis-point spread rather than benefit from congestion, and said the 10% share of protocol net revenue paid to the Arbitrum ecosystem could have covered Solana fees roughly four times over. Robinhood Chain launched on July 1, 2026, as an Ethereum Layer 2 using Arbitrum technology and ETH for gas. Its fees are driven by congestion rather than a fixed posted rate, and the network briefly stalled block production while users continued paying transaction costs. Robinhood’s wallet promotion covers eligible in-app swaps above $0.50 through September 29, but not all onchain activity. Grayscale has named Robinhood Chain among the three leading venues for tokenized stock trading, alongside BNB Chain and Solana. Gnosis co-founder Martin Köppelmann challenged Yakovenko’s argument, noting that Robinhood earns money rather than providing the service for free.
