As the number of chains and rollups continues to grow across Web3, many applications are built on different isolated ecosystems. Although some of these applications are deployed across multiple chains and rollups, their liquidity is inevitably fragmented which is inconvenient to users. Moreover, it is troublesome for the users to move their assets across different ecosystems through centralized exchanges or clumsy bridges. To help combat this, decentralized exchanges may have to embrace the shift into cross-chain ecosystems. Since last year, many cross-chain exchange products have launched. Even SushiSwap and Ren Project released their own crosschain DEX applications too.
