xStocks has announced the launch of xChange, a unified execution layer designed to integrate tokenized stock liquidity across Ethereum and Solana. The platform employs an atomic settlement mechanism, ensuring trades are either fully executed at quoted prices or not executed at all, eliminating the risk of partial fills. xStocks assures that all assets are fully collateralized and pegged 1:1 with underlying U.S. stocks, with prices anchored to real-time public markets.
