The crypto protocol dYdX has undergone a rebranding, officially becoming Arcus, and announced its integration into Robinhood's new blockchain ecosystem. Together, they will launch a decentralized exchange (DEX) that supports perpetual contracts and tokenized stock trading. This partnership tightly couples a traditional retail trading platform with a DeFi derivatives protocol, potentially offering retail users more accessible on-chain financial products.

Key Highlights
Arcus (formerly dYdX) will serve as one of the core protocols on Robinhood's new chain, providing a high-performance perpetual contract matching engine. The tokenized stock feature will allow users to trade on-chain versions of traditional equity assets directly through the DEX, bridging the gap between TradFi and DeFi. Specific launch timelines and supported asset ranges have not yet been disclosed.
