According to DeFiLlama data cited on April 8, 2025, the trading volume on Ethereum-based decentralized exchanges (DEXs) has nosedived by more than 50% from its December 2024 high. The DEX trading volume, which soared to an all-time peak of $66.5 billion last December, dwindled to $31.5 billion in March 2025, indicating a sharp pullback in activity. This decline echoes a wider slowdown in the DeFi space, spurred by a retreat in memecoin frenzy and changing market trends, even as Ethereum remains a linchpin of decentralized finance.
From Boom to Bust

In December 2024, Ethereum DEXs such as Uniswap, Curve, and SushiSwap enjoyed a surge of activity, propelled by a memecoin trading boom and speculative zeal. The $66.5 billion monthly volume affirmed Ethereum’s dominance as the primary hub for DeFi trading platforms. Yet, by March 2025, that number had shrunk to $31.5 billion, reflecting a significant drop from the feverish trading of late 2024. X posts note a steep reduction in memecoin-driven trades as a leading cause, marking a shift away from the speculative wave that once fueled the ecosystem.
The downturn tracks closely with the collapse of the memecoin craze that had previously driven volumes skyward. In contrast to centralized exchanges (CEXs) like Binance and OKX, which held steadier ground with only a minor dip, Ethereum DEXs suffered disproportionately. DeFiLlama data reveals that while CEXs experienced a manageable decline, DEXs struggled to maintain their earlier pace, underscoring their reliance on speculative momentum.
Uniswap Stays Ahead in Tough Times
Despite the Ethereum DEX volumes slump, Uniswap stands out as the leading Ethereum DEX, logging $23 billion in trading volume for March 2025—over 70% of the total. This impressive figure still represents a sharp fall from its December peak of $48 billion. Uniswap’s continued strength highlights its robust framework and deep liquidity pools, outpacing rivals like Curve and SushiSwap, which saw steeper drops relative to their smaller shares. Even so, Uniswap couldn’t dodge the market-wide contraction that hit Ethereum DEXs hard.
The data paints a striking contrast between DEXs and CEXs. While Ethereum DEX volumes crashed by over 50%, centralized platforms saw a less drastic reduction, suggesting traders may be turning to CEXs for reliability or diverse offerings. This split prompts questions about the sustainability of DEX expansion in a post-speculation era.
Reasons for the Fall
Analysts pinpoint the fading memecoin hype as the main culprit. Late 2024 saw an influx of low-cap tokens flooding DEXs, pumping up volumes, but by early 2025, that energy had dissipated, leaving platforms to rely on organic activity. Ethereum’s steep gas fees, though softened by Layer-2 options like Arbitrum and Optimism, might have also pushed smaller traders away, further curbing volumes. Meanwhile, the Total Value Locked (TVL) in Ethereum DeFi protocols has stayed relatively consistent, indicating the volume decline stems from reduced trading rather than a widespread capital flight.
What’s Next?
As of April 8, 2025, the Ethereum DEX landscape faces a critical juncture. With trading volume at $31.5 billion—still notable but well off its high—the sector must navigate a market less propelled by speculative spikes. Uniswap’s persistent leadership offers a ray of hope, yet the broader downturn signals hurdles for Ethereum-based DeFi. Whether this is a fleeting pause or a lasting change depends on the industry’s capacity to spark renewed interest in a more stable market setting.
