Aerodrome processed $4.037 billion in seven-day DEX volume on Base, according to DefiLlama data reviewed on May 27, 2026, at 13:32 UTC, or 6:32 a.m. Pacific Time. The same DefiLlama protocol page showed Aerodrome with $14.188 billion in 30-day DEX volume and $671.7 million in 24-hour DEX volume, all on Base.
The weekly Base-Ethereum comparison is also supported directly by DefiLlama’s chain dashboards. At the same review cutoff, DefiLlama’s Base page showed $7.796 billion in seven-day DEX volume, while DefiLlama’s Ethereum chain page showed $6.99 billion in seven-day DEX volume. That puts Base ahead of Ethereum L1 by roughly $806 million in that rolling seven-day window.
DefiLlama Data Supports a Base-vs-Ethereum L1 Flip
The comparison is limited to Base chain DEX volume versus Ethereum chain DEX volume on DefiLlama. It does not include a combined “Ethereum ecosystem” total, and it does not aggregate other rollups such as Arbitrum, Optimism, Polygon, zkSync or any other L2 into Ethereum’s side of the comparison.
Social-market accounts including Today in DeFi and aixbt highlighted the same narrative, saying Base had flipped Ethereum in weekly DEX volume and that Aerodrome alone processed about $4 billion. Those posts are useful as market-context commentary, but the numerical basis for the article is DefiLlama’s direct dashboard data, not social attribution.
Structural Reading Should Stay Measured
The data supports a time-bound conclusion: Base was ahead of Ethereum L1 in rolling seven-day DEX volume at the May 27 review cutoff, while Aerodrome accounted for more than half of Base’s reported weekly DEX activity. It does not prove a permanent migration of liquidity, a durable execution-layer replacement or a sustained change in Ethereum’s role.
The cleaner interpretation is that Base captured a stronger short-term execution window, with Aerodrome serving as its main liquidity venue. Whether that becomes a lasting market-structure shift will depend on repeat weekly volume, liquidity depth, trading retention and fee conditions, not a single rolling dashboard snapshot.
