ChainCatcher 消息，Arbitrum 联合创始人 Steven Goldfeder 与 Solana 联合创始人 Toly 围绕链上交易费用、MEV 防护及单一排序器模式展开争论。
Steven 表示，不能仅比较表面手续费。Arbitrum One 和 Robinhood Chain 会主动防范抢跑及大部分有害 MEV，而部分宣称手续费更低的链，存在更高的 MEV 成本，包括针对散户的抢跑。他表示，宁愿预先支付明确的费用，也不愿为了较低手续费而承担抢跑、三明治攻击等隐性损失。
Toly 则反驳称，Arbitrum 目前的买卖价差更不利，手续费也更高。仅其从手续费中抽取的 10% 分成，折算成基点后的成本就已超过三明治攻击损耗率，据其估算约为后者的 10 倍，且尚未计入价差影响。他强调：“一个追求股东价值最大化的单一排序器，永远无法胜过无需许可的竞争。”
