Robinhood: Built its own L2 platform on Ethereum due to its emphasis on security and liquidity.

According to Mars Finance, on January 11th, Johann Kerbrat, head of Robinhood's crypto business, stated that the company chose to build its Ethereum Layer-2 network on Arbitrum, rather than launching a separate Layer-1, primarily because it wanted to directly access Ethereum's security, decentralized nature, and EVM ecosystem liquidity, allowing it to focus on core products such as stock tokenization. Robinhood's own L2 is currently in its private testnet phase, and its tokenized stocks have already been deployed on Arbitrum One, enabling seamless migration of assets and liquidity when launching on new chains. To date, the number of Robinhood's tokenized stocks has expanded from approximately 200 initially to over 2000. (CoinDesk)
