Uniswap’s latest version, v4, has witnessed Unichain taking the lead for transaction volume. This milestone marks Unichain’s rapid growth since its launch in February 2025. As of May 2025, Unichain holds an impressive 75% market share, surpassing Ethereum’s declining share below 20%, according to DeFillama data. This dominance is driven by Unichain’s optimized infrastructure: one-second block times and gas fees up to 95% lower than Ethereum’s Layer-1. These advantages, combined with a robust incentive campaign launched in April, have attracted liquidity providers and traders, resulting in over $250 million in total value locked (TVL). Since May 1st, Unichain has handled over $2.613 billion in trading volume, compared to Ethereum’s $1.128 billion. Uniswap’s popularity is also linked to its role as the main engine of Uniswap v4 transactions, highlighting a surge in activity on this new layer-2 network.
