According to CoinMeta, Silhouette has launched the RFQ system on the Hyperliquid mainnet, with the first batch supporting the tokenization of xStocks stocks using Payward. This system allows traders to initiate inquiries regarding xStocks, with market makers bidding for these orders. Settlements are conducted on-chain without any restrictions on volume. xStocks enables trading matching without the need for a separate order book, and tokens with sufficient trading activity can later be migrated to an independent Hypercore market.
