UniChain has emerged as the leader on Uniswap v4, surpassing Ethereum in trading volume. According to data from The Block and Dune Analytics, UniChain now accounts for approximately 75% of the transaction volume on the decentralized exchange's latest iteration. This significantly outpaces Ethereum, which holds under 20% of the volume share on Uniswap v4. UniChain's rise can be attributed to its focus on scalability and lower transaction costs. This makes it an attractive option for traders seeking faster and more affordable DeFi solutions. DeFiLlama data indicates that UniChain boasts a Total Value Locked (TVL) of approximately $800 million. This solidifies its position as the third-largest Layer 2 rollup in terms of TVL, demonstrating growing investor confidence and platform adoption. The shift in dominance highlights the evolving landscape of Layer 2 solutions and their increasing importance in the DeFi ecosystem. ```
