Solana Foundation executive Chase Barker recommended that Robinhood abandon Arbitrum for Robinhood Chain, arguing that Layer 2 networks face inherent performance and fee limitations. He said centralization issues have constrained development and scalability, making L2 infrastructure unsuitable for long-term needs. Barker suggested that Robinhood either build a new high-performance blockchain from scratch or migrate directly to Solana, which he described as a proven public chain capable of addressing scaling challenges facing L2-based solutions.
