Wu said that CryptoRank data shows that only three Ethereum L2 chains had single-day fee revenue of more than $5,000 on January 14, namely Base (about $147,000), Arbitrum (about $39,000) and Starknet (about $9,000). Among them, Base's revenue accounts for nearly 70% of the total Ethereum L2 revenue, showing a clear lead. The combined revenue of all remaining L2s is just over $15,000.
