Solana co-founder Toly pushed back against Arbitrum co-founder Steven Goldfeder’s claim that crypto users should not fall into a “narrative trap” of simply comparing on-chain transaction fees. Toly said Arbitrum currently has wider bid-ask spreads and higher fees, arguing that the cost represented by Arbitrum’s 10% fee take alone exceeds sandwich trading rates. Including the worse spread, he estimated total costs are about 10 times higher. He added that a single-sequencer model focused on maximizing shareholder interests cannot beat permissionless market competition. Goldfeder had argued that Arbitrum One and Robinhood Chain actively defend against harmful MEV such as frontrunning, while some chains marketed as low-fee may impose higher hidden MEV costs on retail users through frontrunning and sandwich attacks.
