Robinhood CEO Vlad Tenev announced that the Arbitrum-based Ethereum Layer 2 network, Robinhood Chain, processed 4 million transactions during its first week of public testing. The network aims to support tokenization of real-world assets and on-chain financial services, with integration from partners like Alchemy, LayerZero, and Chainlink. The mainnet is expected to launch later this year to enable 24/7 trading with near real-time settlement.
