Ethereum's Layer 2 solutions, like Optimism, Arbitrum, and zkSync, face user fragmentation challenges. These rollups operate independently, creating separate ecosystems with distinct liquidity pools, dApps, and user bases. This fragmentation can lead to poor user experiences, as assets and data are siloed across chains, requiring complex bridging solutions that increase costs and risks. For example, moving tokens between Layer 2s often involves high gas fees and delays, discouraging seamless interaction. Additionally, developers must choose which Layer 2 to build on, splitting resources and potentially limiting dApp adoption. While initiatives like the Superchain aim to unify Optimism-based rollups, interoperability remains a hurdle. Without standardized protocols or robust cross-chain solutions, user fragmentation could hinder Ethereum's scalability and ecosystem cohesion, despite Layer 2s' ability to reduce mainnet congestion.
