Nado has introduced the first tokenized U.S. equities unified margin system, allowing SPYx (S&P 500) and QQQx (NASDAQ-100) to be used as collateral for perpetual contracts. This innovation enables users to trade cryptocurrencies, forex, commodities, and stock perpetual contracts within a single account, leveraging tokenized U.S. equities as margin. The system offers portfolio-based settlement through a unified risk management framework. This development marks a significant milestone in the derivatives market, as it is the first instance of U.S. equity assets being integrated into a multi-asset perpetual contract margin system. Nado's platform now supports U.S. equities as cross-asset unified margin, enhancing capital efficiency in on-chain trading markets.
