According to Matt Hougan, Robinhood is actively evaluating whether to use Solana or Arbitrum as the blockchain backbone for its upcoming service that will allow European retail investors to trade US stocks. This development highlights the growing institutional adoption of blockchain technology in traditional finance, with a focus on transaction speed, costs, and scalability—key factors for crypto market performance. The decision between Solana and Arbitrum could influence network adoption rates and token demand, making both assets important to watch for traders. The long-term outlook for crypto remains driven by crypto-specific fundamentals rather than macroeconomic rate changes, reinforcing the importance of blockchain utility in global financial services (source: Matt Hougan on Twitter, May 7, 2025).
