Base's revenue split is worth examining closer. The layer 2 captures roughly 92% of the fees it collects, while only paying Ethereum for blob space—the cost difference reveals a pretty sharp margin advantage. This highlights how Base's architecture actually pencils out economically compared to settling data with Ethereum. The fee arbitrage here isn't accidental; it's baked into how the chain scales. Worth noting as these economic models shape which chains attract liquidity and volume long-term.
