About Arcus
Arcus is a decentralized exchange built in partnership with Robinhood Chain, combining brokerage-scale consumer experience with DeFi-native infrastructure. Users get one self-custodial account to trade Stock Tokens (spot, with zero fees, 24/7) and cross-margined perpetual futures across equities, crypto, commodities, and indices, with up to 50x leverage. The platform offers 95+ markets including 80+ US and international equities, indices like SPY and QQQ, commodities, and major crypto assets such as BTC, ETH, and SOL. Arcus is described as the next chapter for the team that built dYdX, with dYdX Chain continuing to operate separately while Arcus introduces new asset classes on a chain purpose-built for high-throughput trading. It provides API trading with order management, account data, and market feeds, and is not available to users in the United States, United Kingdom, Canada, or other restricted jurisdictions.
