Robinhood vs. Vitalik: Why the trading app is building it own L2 while Ethereum founder cools on them

In the ongoing debate within the cryptocurrency community, the contrast between Robinhood and Vitalik Buterin highlights a crucial divergence in perspectives. Robinhood, the popular trading app known for democratizing access to financial markets, is making strategic moves to enhance its platform by developing its own Layer 2 (L2) solution. This initiative aims to improve transaction speeds and reduce costs for its users, ultimately seeking to create a more efficient trading environment. On the other hand, Vitalik Buterin, the co-founder of Ethereum and a prominent figure in the blockchain space, has recently expressed a cooled relationship with the popular trading app. His skepticism may stem from concerns about the implications of centralized trading platforms on the broader goals of decentralization and the ethos of the cryptocurrency movement. This situation raises important questions about the future of trading platforms, the evolving relationship between centralized and decentralized finance, and what these developments mean for the overall landscape of blockchain technology and user experience. source: https://www.coindesk.com/tech/2026/02/19/robinhood-testnet-l2-logs-4-million-transactions-following-vitalik-questions-of-ethereum-s-rollup-roadmap
