[Ethereum Sacrifices Over $100 Million in Revenue for Ecosystem Expansion in 2025] In 2025, the Ethereum network demonstrated strong operational performance, processing record-breaking transaction volumes and maintaining dominance in the DeFi market (with the mainnet TVL accounting for 64%). However, the price of ETH fell by 10% throughout the year to below $3,000, decoupling from network activity. Ethereum implemented technical upgrades to reduce transaction fees, promoting L2 network growth and ecosystem expansion, which led to a significant decline in mainnet revenue. In 2025, total L2 revenue dropped by 53% to $129 million, with only $10 million paid to the mainnet, while L2 operators retained approximately $119 million in profits. The potential revenue of the Ethereum mainnet decreased by about $103 million, subsidizing ecosystem expansion.
