[Nado Pioneers Tokenized US Stock Unified Margin, Enabling On-Chain Cross-Asset Trading] According to TechFlow, on June 9, Nado announced the launch of the industry's first tokenized US stock unified margin system. SPYx (S&P 500) and QQQx (Nasdaq 100) are now supported as perpetual contract margins. Users can use tokenized US stocks as collateral within a single Nado account to trade cryptocurrencies, forex, commodities, and stock perpetual contracts, with portfolio settlement conducted through a unified risk management system. This marks the first time in the derivatives market that US stock assets have been integrated into a multi-asset perpetual contract margin system. Nado thus becomes the first trading platform to support US stocks as unified cross-asset margin, bringing prime broker-level capital efficiency to the on-chain trading market.
