Silhouette Launches RFQ Trading System on Hyperliquid Mainnet

Silhouette, a block trading layer on Hyperliquid, has launched its Request for Quote (RFQ) system on the mainnet. The platform initially supports xStocks, a tokenized stock framework by Payward. The system enables 24/7 large-scale trading without a dedicated order book, allowing market makers to compete for quotes. Since its launch in June 2025, xStocks has processed over $40 billion in volume with a current market cap of approximately $620 million.
