According to CryptoSlate, Ethereum's on-chain transaction volume and DeFi market share hit an all-time high in 2025, but mainnet fee revenue saw a significant decline. Data shows that Layer-2 networks generated a total annual revenue of approximately $129 million, paying only about $10 million to the Ethereum mainnet for settlement and security, while the remaining $119 million was retained by Layer-2 operators. This means Ethereum gave up over $100 million in potential fee revenue this year. Among them, Coinbase's Base network generated over $75 million in revenue, accounting for nearly 60% of total Layer-2 revenue. Due to the Dencun upgrade reducing fees, ETH's price dropped about 10% within the year, weakening its deflationary effect. However, Ethereum's share of TVL in DeFi still increased to around 64%. https://www.(wublock123.com)/index.php?m=content&c=index&a=show&catid=6&id=54445
