Robinhood's new Ethereum Layer 2 testnet, built on Arbitrum, processed four million transactions in its first week, marking a significant milestone in the company's blockchain ambitions. The testnet, known as Robinhood Chain, is designed to support tokenized equities, ETFs, and other real-world assets, aiming to revolutionize on-chain financial services. CEO Vlad Tenev highlighted the rapid adoption, noting that developers are actively building on the platform, which is structured as a permissionless, high-throughput network. Infrastructure partners such as Alchemy, Layerzero, and Chainlink are already integrated, enhancing the chain's capabilities. Robinhood plans to launch the mainnet later this year, positioning itself as a key player in the tokenized finance sector.
