Arbitrum and Solana Co-Founders Clash Over Robinhood's Chain Fee Model

Arbitrum's co-founder Steven Goldfeder and Solana co-founder Toly are engaged in a heated debate over Robinhood's Chain fee model and underlying network choice.

Toly claims that the 10% revenue share paid to Arbitrum by Robinhood is enough to cover four times the transaction fees on the Solana chain, implying that deploying on Solana would significantly reduce user gas costs.

Goldfeder counters that Robinhood can retain around 90% of gas income when running on the Arbitrum architecture, which he argues is why they chose it. He emphasizes that this choice allows them to be 'landlords, not tenants.'

Toly disputes this by suggesting that Robinhood could charge users fees directly and use a cheaper underlying network, but Goldfeder retorts that many on-chain activities do not pass through the Robinhood frontend, meaning they would miss out on revenue from these external activities.
