Base processes over 10 million transactions per day, with users paying an average fee of only $0.01. If these transactions were executed on the Ethereum mainnet, the ETH fees would exceed $200 million. What is the cost? Transaction value has been transferred — a leading platform retains sequencer revenue, and the fee economy of the mainnet is bypassed. Arbitrum and Optimism are also copying this model. This is the paradox of L2 scaling: they indeed reduce user costs but alter the flow of value within the entire ecosystem. L2 should be Ethereum's scaling solution, but instead, it has become a channel that diverts economic value from the mainnet. This issue warrants serious consideration by the Web3 community.
