The phenomenon of fee inversion between the Ethereum mainnet and Layer2 has begun to appear. According to the latest data, the withdrawal cost on the mainnet is actually lower than many L2 solutions—this reversal is indeed worth pondering.

From a logical perspective, the core selling point of Layer2 is to reduce Gas fees and improve transaction speed. However, as the mainnet upgrades and optimizes, and as competition among L2 ecosystems intensifies, the fee structures during certain periods have experienced subtle changes. Some users are beginning to ask: Is L2 still necessary?

In fact, this reflects market self-adjustment. Each optimization of the mainnet narrows the cost advantage of L2, and competition among L2s is also driving down the fee expectations across the entire ecosystem. This pressure will ultimately promote further technological iteration—either L2 continues to optimize its cost structure or seeks differentiated value beyond fees (such as unique ecosystems, cross-chain capabilities, etc.).

While it may seem dramatic in the short term, the long-term multi-chain ecosystem competition is actually healthy.
