📰 Solana co-founder Toly again went head-to-head with Arbitrum co-founder Steven Goldfeder, and this time they were arguing the same old point: don’t just look at the surface fee.

Toly’s point was very straightforward: Arbitrum now has a wider bid-ask spread and higher fees; if you only count the 10% cut in the fee, the cost is already higher than the sandwich trading fee rate, and when you factor in the worse spread, he estimates the overall cost can be about 10 times higher.

💡 Steven’s view wasn’t unreasonable either. He emphasized that both Arbitrum One and Robinhood Chain are designed to prevent front-running and harmful MEV. Many people like to talk about “low fees,” but in the end retail users may be slowly eaten away by hidden costs like front-running and sandwich attacks.

Honestly, the essence of this debate is not who is louder, but whether everyone cares more about the “visible fee” or the total amount spent on the whole transaction. As for the single-sequencer model, Toly directly said it can never beat permissionless market competition.

🤔 At times like this, when looking at a chain, you really can’t just stare at one number. Would you trust something that is “cheap but may have hidden losses,” or “a bit more expensive but has a more stable mechanism”?
