Solana’s Toly Hits Back at Arbitrum: Single Sequencer Costs More

This exchange moves beyond headline fee comparisons to expose the true cost drivers in L2 design: spread and fee structure, not just sticker price. Toly's point challenges the narrative that lower nominal fees equal cheaper execution, a distinction that matters for traders and liquidity providers evaluating rollup efficiency. The dispute underscores how sequencer centralization and fee mechanics shape real user costs. Whether Arbitrum's fee model proves more competitive as usage scales is the open question, especially as both ecosystems court institutional flows.
