The race for ecosystem development among Layer 1 chains could lead to user fragmentation. As chains compete to attract developers and users with unique features, interoperability remains a challenge. Distinct protocols, wallets, and dApps create silos, forcing users to navigate multiple ecosystems, each with its own learning curve and tools. This fragments liquidity, attention, and adoption, as users may stick to one chain for convenience, missing broader opportunities. Cross-chain solutions like bridges or interoperability protocols aim to mitigate this, but they introduce complexity and security risks. A unified user experience across chains is critical to prevent fragmentation and ensure seamless adoption, but achieving it requires collaboration over competition.
